Abstract

A method for manufacturing a fibrous product comprising rotating in synchronism, a first roll having a first cutting blade and a first abutment and a second roll having a second cutting blade and a second abutment so that the first cutting blade is opposed to the second abutment and the first abutment is opposed to the second cutting blade. The first and second rolls are in parallel with each other to have roll axes a distance apart from each other. A fibrous product is fed between the first and second rolls so that the product is cut only halfway through the thickness from one side thereof with the product held between the first cutting blade and the second abutment and the product is also cut only halfway through the thickness from the other side thereof with the product held between the first abutment and the second cutting blade.

Claims (3)

1. A method for manufacturing a fibrous product comprising:
rotating a first roll having a first cutting blade and a first abutment and a second roll having a second cutting blade and a second abutment in synchronism with each other so that the first cutting blade is opposed to the second abutment and the first abutment is opposed to the second cutting blade, the first roll and the second roll being installed in parallel with each other to have roll axes a distance apart from each other; and feeding a fibrous product between the first roll and the second roll so that the fibrous product is cut only halfway through the thickness from one side thereof with the fibrous product held between the first cutting blade and the second abutment and the fibrous product is also cut only halfway through the thickness from the other side thereof with the fibrous product held between the first abutment and the second cutting blade.
2. The method for manufacturing a fibrous product according to claim 1, wherein the fibrous product includes a substrate sheet and two fiber bundle layers disposed on and locally bonded to two sides of the substrate sheet, respectively, wherein one of the fiber bundle layers is cut by the first cutting blade and the other is cut by the second cutting blade.
3. The method for manufacturing a fibrous product according to claim 2, wherein the fibrous product is a cleaning article in which the fiber bundle layers thus cut have an effect of collecting dust.
