Abstract

Abrasive belt with an abrasive-grain layer on a base containing a textile material, and with a joint extending transversely to its longitudinal direction. The latter contains a joining strip in a rebate on the side of the base facing away from the abrasive-grain layer. A set of parallel threads of the textile material extends transversely to the joint. To increase the quality of the joint, the textile material used is one in which the set of parallel threads forms a non-interwoven layer. This thread layer is arranged on the side of the textile material facing the abrasive-grain layer. This layer is held together by a further layer arranged on its side facing away from the abrasive-grain layer. Since the rebate is located in this further layer, the threads responsible for transmitting the longitudinal tensile forces and extending transversely to the joint remain unaffected.

Description

Die Erfindung betrifft ein Schleifband mit einer Schleifkornschicht auf einer ein textiles Material enthaltenden Unterlage und mit einer quer zu seiner Längsrichtung verlaufenden Verbindungsfuge, die ein Verbindungsband in einer Ausfalzung auf der der Schleifkornschicht abgewandten Seite der Unterlage enthält, wobei eine Schar von zueinander parallelen Fäden des textilen Materials quer zu der Verbindungsfuge verläuft.The invention relates to an abrasive belt with a layer of abrasive grain on a base containing a textile material and with a connecting joint running transversely to its longitudinal direction, which contains a connection belt in a fold on the side of the base facing away from the abrasive grain layer, wherein a family of parallel threads of the textile Material runs across the joint.

Es ist bekannt, die miteinander zu verbindenden Ränder eines Schleifbands im Bereich der Verbindungsfuge mit einem Verbindungsband zu überbrücken, das in der rückseitigen Ausfalzung des Bandes an Ort und Stelle aus erhärtetem Material gegossen (US-PS 4215516) oder vorgefertigt eingeklebt wird (FR-PS 928 656). Für die Herstellung der Ausfalzung wird ein Teil der Unterlage einschließlich des darin enthaltenden Gewebes entfernt, so daß der verbleibende Teil geschwächt wird. Auch wenn die Ausfälzung sich nur über einen geringeren Teil als die Hälfte der Gewebedicke erstreckt oder wenn die Ausfälzungsflächen geneigt verlaufen (US-PS 3 154 897), läßt sich nicht vermeiden, daß auch die quer zur Fuge verlaufenden Fäden des Gewebes in denjenigen Bereichen unterbrochen oder mindestens geschwächt werden, in welchem sie im Bereich eines Bindungspunktes unter den quer zu ihnen verlaufenden Fäden hindurchgehen. Häufig verzichtet man, um diese Schwächung zu vermeiden, auf eine vollständige Einsenkung des Verbindungsbandes in der Ausfalzung, was aber den Nachteil hat, daß das Verbindungsband rückseitig über die Bandoberfläche störend vorsteht.It is known to bridge the edges of an abrasive belt to be connected to one another in the region of the connecting joint with a connecting belt which is cast in place in the rear fold-out of the belt from hardened material (US Pat. No. 4,215,516) or pre-glued (FR-PS 928 656). For the production of the fold-out part of the base including the tissue contained therein is removed, so that the remaining part is weakened. Even if the fold-out extends only over a smaller part than half the fabric thickness or if the fold-out surfaces are inclined (US Pat. No. 3,154,897), it cannot be avoided that the threads of the fabric running transverse to the joint are also interrupted in those areas or at least weakened, in which they pass in the area of a tie point under the threads running transversely to them. Often, in order to avoid this weakening, the connecting band is completely countersunk in the rebate, but this has the disadvantage that the connecting band protrudes on the back over the band surface.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Schleifband der eingangs genannten Art zu schaffen, in welchem die genannte Schwächung durch die Ausfalzung der Verbindungsfuge vermieden oder vermindert wird.The invention is therefore based on the object of providing an abrasive belt of the type mentioned in the introduction, in which the weakening mentioned is avoided or reduced by the fold-out of the connecting joint.

Die erfindungsgemäße Lösung besteht darin, daß die Schar von zueinander parallelen, quer zur Verbindungsfuge verlaufenden Fäden eine nicht verwebte, auf der der Schleifkornschicht zugewandten Seite des textilen Materials gelegene Schicht bildet, die durch eine auf ihrer der Schleifkornschicht abgewandten Seite befindliche weitere Schicht zusammengehalten ist, in welcher sich die Ausfalzung für die Bandverbindung befindet.The solution according to the invention consists in that the family of mutually parallel threads running transversely to the connecting joint forms a non-woven layer on the side of the textile material facing the abrasive grain layer, which is held together by a further layer on its side facing away from the abrasive grain layer, in which the fold for the band connection is located.

Die Erfindung beruht auf der Erkenntnis, daß bei der Verwendung einer bestimmten Art von textilen Flächengebilden das als solches in Schleifbändern bekannt ist (EP-PS 0 045 408; DE-PS 2 333 980) die schichtförmige Anordnung der verschiedenen Fadenlagen in der Schleifbandunterlage die Möglichkeit gibt, diejenige Fadenlage, die für die Übertragung der Längszugkräfte im Schleifband hauptsächlich verantwortlich ist, in der der Schleifkornschicht zugewandten Unterlagenschicht anzuordnen und die Ausfalzung für die Schleifbandverbindung im wesentlichen in der anderen, rückseitigen Schicht des textilen Flächengebildes vorzusehen und dadurch die für die Übertragung der Längszugkräfte verantwortliche Fadenlage vor einer Schwächung durch die Ausfalzung vollständig oder weitgehend zu bewahren.The invention is based on the knowledge that when a certain type of textile fabric is used, which is known as such in abrasive belts (EP-PS 0 045 408; DE-PS 2 333 980), the layered arrangement of the different thread layers in the abrasive belt underlay offers the possibility there, the thread layer which is mainly responsible for the transmission of the longitudinal tensile forces in the sanding belt, to be arranged in the backing layer facing the abrasive grain layer and to provide the rebate for the sanding belt connection essentially in the other, rear layer of the textile fabric, and thereby for the transmission of the longitudinal tensile forces To fully or largely protect the responsible thread position from weakening due to the folds.

Während das textile Material im Zusammenhang der Erfindung stets eine Schicht mit quer zur Verbindungsfuge laufenden Fäden, die für die Übertragung der Längszugkräfte des Schleifbandes verantwortlich ist, enthalten muß, besteht in der Auswahl derjenigen Schicht, die die Fäden der erstgenannten Schicht zusammenhält und rückseitig von dieser angeordnet ist, weitgehende Freiheit. Vorzugsweise wird aber auch diese Schicht von einem Fasermaterial, vorzugsweise einer quer zu den Fäden der erstgenannten Schicht verlaufenden Fadenschar, gebildet, wobei die Schichten durch beliebige Mittel verbunden sein können, vorzugsweise aber in der Art eines Nähgewirks (wie dies beispielsweise in der EP-PS 0 045 408 und der darin bezeichneten Literatur beschrieben ist).While the textile material in the context of the invention must always contain a layer with threads running transversely to the connecting joint, which is responsible for the transmission of the longitudinal tensile forces of the abrasive belt, there is the choice of the layer which holds the threads of the first-mentioned layer and on the back thereof is arranged, extensive freedom. However, this layer is preferably also formed from a fiber material, preferably a family of threads running transverse to the threads of the first-mentioned layer, the layers being able to be connected by any means, but preferably in the manner of a knitted fabric (as is the case, for example, in EP-PS 0 045 408 and the literature described therein).

Bei normal breiten Schleifbänden können die Kettfäden des textilen Materials in Längsrichtung des Bandes verlaufend die Schar der zueinander parallelen Fäden bilden; in diesem Fall ist im allgemeinen nur eine Verbindungsfuge vorgesehen.In the case of sanding belts of normal width, the warp threads of the textile material running in the longitudinal direction of the belt can form the family of threads parallel to one another; in this case only one connecting joint is generally provided.

Wenn es sich jedoch um ein Schleifbreitband handelt, dessen Breite größer ist als die Herstellungsbreite üblicher, für die Verwendung der Unterlage verwendete Textilbahnen, ist eine Mehrzahl von Verbindungsfugen vorgesehen, wobei die Schar der zueinander parallelen, quer zu den Verbindungsfugen verlaufenden Fäden von den Schußfäden des textilen Materials gebildet ist.However, if it is an abrasive wide belt, the width of which is greater than the production width of conventional textile webs used for the use of the underlay, a plurality of connecting joints is provided, the family of parallel threads running transversely to the connecting joints being separated from the weft threads of the textile material is formed.

Die Angabe, daßdie für die Übertragung der Längszugkräfte verantwortlichen Fäden quer zur Verbindungsfuge verlaufen, dient lediglich zu deren Identifizierung, nicht aber zur Angabe eines bestimmten Winkels zwischen diesen Fäden und der Verbindungsfuge. Insbesondere ist es nicht erforderlich, daß ein rechter Winkel zwischen diesen Fäden und der Verbindungsfuge besteht. Ebenso wenig brauchen diese Fäden genau in Längsrichtung des Schleifbandes zu verlaufen.The statement that the threads responsible for the transmission of the longitudinal tensile forces run transversely to the connecting joint serves only to identify them, but not to indicate a specific angle between these threads and the connecting joint. In particular, it is not necessary that there be a right angle between these threads and the connecting joint. Nor do these threads need to run exactly in the longitudinal direction of the grinding belt.

Die Verbindungsfuge kann einen beliebigen Verlauf haben. Sie muß nicht unbedingt gradlinig sein, sondern kann beispielsweise auch gewellt oder gezackt sein.The connection joint can have any course. It does not necessarily have to be straight, but can also be wavy or jagged, for example.

Die Ausfalzung kann im Querschnitt durch die Fuge rechtwinklig begrenzt sein. Sie kann auch an jedem der beiden zu verbindenden Ränder keilförmig schräg oder bogenförmig verlaufen. Sie hat zweckmäßigerweise in Längsrichtung der Fuge konstanten Querschnitt; jedoch kann man die Ausfalzung auch aus einer Reihe hintereinander angeordneter Nuten zusammensetzen, die in Längsrichtung des Bandes oder in Längsrichtung der quer zur Fuge verlaufenden Fäden verlaufen, wie dies an sich bekannt ist.The fold-out can be limited at right angles in cross-section by the joint. It can also run at either of the two edges to be connected in a wedge-shaped incline or arc. It expediently has a constant cross section in the longitudinal direction of the joint; however, the rebate can also be composed of a series of grooves arranged one behind the other, which run in the longitudinal direction of the band or in the longitudinal direction of the threads running transversely to the joint, as is known per se.

Die Erfindung wird im folgenden näher unter Bezugnahme auf die Zeichnung erläutert, die ein vorteilhaftes Ausführungsbeispiels in einem schematischen Querschnitt durch eine Schleifband-Verbindungsfuge veranschaulicht.The invention is explained in more detail below with reference to the drawing, which illustrates an advantageous embodiment in a schematic cross section through an abrasive belt connection joint.

Die Schleifkornschicht 1 wird getragen von einer flexiblen Unterlage, die als tragendes Textilmaterial ein Nähgewirk enthält, das aus zwei Schichten besteht, von denen die obere, unmittelbar unterhalb der Schleifkornschicht 1 gelegene Schicht eine Schar von Fäden 2 enthält, die etwa in Längsrichtung des Schleifbandes verlaufen, während die zweite, darunter gelegene Schicht aus quer zu den Fäden 2 verlaufenden Fäden 3 besteht. Bei 4 enthält das Schleifband eine quer zu seiner Längsrichtung und quer zur Zeichenebene verlaufende Verbindungsfuge, die daher auch quer zur Richtung der Fäden 2 verläuft. Die Verbindung wird vermittelt durch ein Verbindungsband 5, das eingelegt ist in eine Ausfalzung der beiderseits der Fuge miteinander zu verbindenden Ränder. Die Tiefe der Ausfalzung gleicht der Dicke des Verbindungsbandes 5, so daß dieses vollständig darin enthalten ist. Dies ist vorteilhaft aber nicht in allen Fällen unbedingt erforderlich.The abrasive grain layer 1 is supported by a flexible base, which contains a sewing fabric as a supporting textile material, which consists of two layers, of which the upper layer immediately below the abrasive grain layer 1 contains a family of threads 2 which run approximately in the longitudinal direction of the grinding belt while the second, Darun ter layer consists of threads 3 running transversely to the threads 2. At 4, the abrasive belt contains a connecting joint running transversely to its longitudinal direction and transversely to the plane of the drawing, which therefore also runs transversely to the direction of the threads 2. The connection is mediated by a connecting band 5, which is inserted into a rebate of the edges to be connected to one another on both sides of the joint. The depth of the fold is equal to the thickness of the connecting band 5 so that it is completely contained therein. This is advantageous but not absolutely necessary in all cases.

Die Tiefe der Ausfalzung gleich der Dicke der von den Fäden 3 gebildeten Schicht, so daß nur das dieser Schicht angehörende Material bei der Herstellung der Ausfalzung entfernt wurde, während die von den Fäden 2 gebildete Schicht unverletzt ist. Die Zugkräfte können unmittelbar von den Fäden 2 der einen Fugenseite auf das Verbindungsband 5 und von diesem auf die Fäden 2 der anderen Verbindungsseite übertragen werden.The depth of the folds is equal to the thickness of the layer formed by the threads 3, so that only the material belonging to this layer was removed during the production of the folds, while the layer formed by the threads 2 is undamaged. The tensile forces can be transmitted directly from the threads 2 on one side of the joint to the connecting band 5 and from there to the threads 2 on the other side of the connection.

Die Erfindung führt zu einer Fugenverbindung hoher Belastbarkeit und Sicherheit.The invention leads to a joint connection of high resilience and security.

Der Aufbau des Verbindungsbands 5 sowie die Technik seiner Verbindung mit dem Schleifband können von bekannter Art sein.The structure of the connecting belt 5 and the technology of its connection to the grinding belt can be of a known type.
