- ABSTRACT 52 us. Cl ..l56/51 Stripes are pp to i sulated Wire by passing it between two [5 1 Int CL "01b 19/04 endless belts at least one of which carries ink or transverse 58] Field 101/3646 marking areas. The belts are canted at opposite angles so that the wire is caused to roll across the printing surface.
- SUMMARY l have invented an apparatus formarlging a continuously advaneing strand comprising two endless beltsthat roll. the strand as it passes between them.
- first endless belt has a surface adjacentto the strand and advancing in a line having afirst component with the same speedand direction as, the strand and a second component with adirectiontransverse of the strand.
- My apparatus also-comprises asecond endless belt with a surfacefacinggthe surface of i the first beltand advancing in a line having-one component with the same speed anddirectionas the strandand another component transverse of the strand but in a-direction opposite to the direction of the second component of thefirst endless belt.
- the surface of at least one of thebe'lts comprises printing areas that engage .the strand and the apparatus also comprises means for applying marking composition to these areas and means for guiding the strand between lthe .belts so that itis rotated byibelt friction and urged to roll over the, printing areas and be marked by them.
- my apparatus will roll 'tfi strand substantially 360 so that where theprinting.areasfwhich, preferably, are straight edged, are normal tothe line of advance of the strands the markings will take the form of circular stripes around the strand circumference and where the printing areas are oblique to the lines of advance oftlre strands they will produce helical stripes.
- the printing areas may be raised, intaglio, or smooth for offset marking, and marking areas may be comprised on both of the belts. In the latter case each belt may have a different color composition or ink or one or both beltsmay have different inks applied to different of its printing areas.
- FIG. 6 shows a side view of an embodiment of a feature of w my invention.
- FIG. 7 shows a plan of the steps in the method of my invention.
- FIG. 8 shows a side view of an'element of FIG. 7.
- My invention features a structurewherein the belts 13, 14 are not in alignment but are oppositely canted to the line of advance of the strand 11, which is being urged forward by a takeupapparatus, not shown in the drawing.
- the takeup apparatus may comprise a capstan and takeup reel but it may also comprise some manufacturing apparatus, such as a strander, and the strand may be paid into the apparatus 10 from a storage reel but my invention has particular utility where the strand 11 is supplied directly from some manufacturing step such as insulation extrusion.
- the belts-l3, 14 are canted they have the effect of twisting the strand 1] around its own axis and rolling it over the surface of the belts. This comes about because the motion of the surface of each of the belts 13, 14 facing the strand comprises one component having the same speed and direction as the strand and one component normal to the strand direction.
- the normal component has a direction to the left, looking downstream of the strand movement, and the belt 13 a component to the right so that, again looking downstream, the strand, while it is gripped by the belts, is twisted clockwise as indicated by the arrow a.
- the strand is released downstream of the belts it is free to untwist as indicated by the arrow b.
- insulated electrical wires I have found that the necessary twist can be applied by my apparatus without overtwisting or otherwise damaging the strand.
- the apparatus 10 applies the circular, spaced apart, marks 12 to the strand 11 by means of raised printing areas 17-17 on the lower belt 14 that have straight edges 18, 19 normal to the axis of advance of the strand 11. Since the belt 14 is canted by an angle a from the strand 11 the edges 18, 19 are required to form the same angle a with a line normal to the motion of the belt 14.
- the upper belt 13 is not used for printing but serves merely to guide and twist the strand 11. Raised areas 21-21 on the belt 13 are positioned to contact the strand 11 at points between the stripes 12 so as not to smear the latter, but, as shown in FIG.
- a marking composition 22, different, if desired, from the color of the composition 16 may be applied to the areas 21 to apply additional stripes.
- the composition 22, 16 are applied respectively to the areas 21, 17 by inking rolls 23, 24 which are coated by rolls 26, 27 in a known manner.
- Apparatus of the type shown for transferring marking composition to inking rolls is commercially available, and this and other known types of ink transfer apparatus can be used within the scope of my invention of which it does not comprise a novel feature.
- Suitable marking compositions may be designated as inks, paints, lacquers etc. but I have used the words ink and printing broadly within this specification to designate the marking composition of whatever type and the transfer area for transferring this composition to the strand surface.
- the belt 13 is mounted on rolls 28, 29 and the belt 14 on rolls 31, 32 of which the rolls 29 and 32 are driven by means of gears 33, 34, sprockets 36, 37, 38 and chains 39, 40 or other gear means of which many known types and combinations are available.
- the sprocket 38 is synchronized with the takeup for the strand 11 by known types of apparatus, not shown, to drive the belts 13, 14 to have the component of their motion that is parallel with the strand l1 advance at the speed of the strand.
- the method by which circular marks are applied by the apparatus 10 is shown in FIG. 2 where, for the sake of clarity, the strand is shown without any ink being applied to the upper belt. As seen in FIG.
- a mark 41 applied by a raised area 42 has just become visible in the side view while a mark 43 applied by a raised area 44 shows a greater extent due to the twisting of the strand 10 by the belts.
- a mark 43 applied by a raised area 44 shows a greater extent due to the twisting of the strand 10 by the belts.
- each of the marks is greater until the final mark 46 made by the raised area 47 makes a complete circle around the strand.
- the width of the belts 13, 14 and of the printing areas 17 need be no greater than 1r Dcosa where D is the diameter of the strand 11, but I prefer to add to this width to provide for normal tolerances and also to permit the use of a single set of belts for strands of different diameter.
- the width of the belts can be further narrowed, however, by providing printing areas on the upper belt which register with the areas of the lower belt, requiring each belt to print only a semicircle. In the structure of FIG. 1 this would be accomplished by shifting the phase of the areas 21 to register with the areas 17 and coating the areas 21 with the same ink 16, as with the rolls 23, 26, 27.
- the belts 13, 14 may comprise a rubberized fabric but they may be steel or have steel ribbon backing or a reinforcement of steel wires to provide sufficient rolling pressure to the strand 11. This pressure may also be supplied by backing rolls 47-47 (FIG. or smooth surfaced backing plates, not shown.
- FIG. 3 I have illustrated an intaglio marking apparatus where belts 48, 49 are steel and marking areas 51-51 are etched into the surfaces of the belt 49 to hold a suitable gravure type ink.
- Offset printing in accordance with my invention is exemplified by the apparatus of FIG. 5 where the ink is transferred to a rubber belt 52 from a transfer roll 53 which is wetted in the known lithographic manner by the rolls 54 from a water tank 56 and inked by the rolls 57 from an ink supply tank 58.
- the distance d normal to the strand, between stripes should equal n-D where D represents the strand diameter.
- a left hand helix may be marked by sloping the printing stripes in the opposite direction and a pattern of crossing helices or other marking may, of course, be printed by my apparatus.
- FIG. 6 will permit the application of different colored stripes when only one of the belts is used for printing.
- a lower belt 63 with raised stripes 64 has some of the printing areas of the stripes coated with one color ink 66 from a half cylinder roll 67 and other areas coated with an ink 68 from a half cylinder roll 69.
- Multiple colors can also be applied by passing a strand through more than one of the apparatus 10 in tandem, each supplied with a different ink, and having the belts synchronized to avoid overlapping of the markings.
- the use of two belt printers of my invention in tandem, each supplied with a different ink has an important advantage even when only one color code is applied to any single wire, for it permits a change in the color code without interrupting the manufacturing operation. To change colors in this method the upper belt assembly of one apparatus is lifted at the same time that the other is lowered.
- conductors 71, 72 (FIG. 7) are paid from mounted reels 73, 74 past guide sheaves 77, 78 into an extrusion machine 79 where both the conductors are covered with polymeric insulation of the same color and composition to emerge as insulated conductor strands 81, 82.
- the strands 81, 82 pass through a cooling trough 83 in the customary manner whereafter the strand 81 passes through a double belt marking apparatus 84 of the type hereinabove described wherein the strand 81 is temporarily twisted and marked with the desired coding.
- the strander 87 comprises a takeup reel 88, capstan 89 and guide sheaves 91-94.
- Stranders of the type described are commercially available and other suitable stranders are also known that can be used in the practice of my invention.
- Marking of the strand 81 by the apparatus 84 will suffice to distinguish the members of the pair 86 from each other. Where further coding is desired, distinguishing marking can be applied to the strand 82 by an apparatus 96 similar to the apparatus 84. Where it is desired to change the coding without interrupting the extrusion and stranding operations I have provided additional marking apparatus units 97, 98 which can be brought into operation when the units 81, 82 are deactivated, without interruption of the manufacturing process, as shown in FIG. 8.
- Apparatus for marking continuously advancing strand comprising:
- D. means applying marking composition to said areas
- E. means guiding said strand between said belts whereby said strand is rotated by the belt friction in said transverse components and urged to roll over said printing areas and be marked thereby.
- both of said belts comprise printing areas.
- An apparatus of claim 1 comprising means applying different color compositions to different of said areas.
- both of said belts comprise printing areas.
- An apparatus of claim 2 comprising means applying different color compositions to different of said areas.
- An apparatus of claim 3 comprising means applying different color compositions to different of said areas.
- An apparatus of claim 4 comprising means applying different color compositions to different of said areas.
