Apparatus and method for raising a fluffy surface on cloth

摘要

A method for obtaining a fluffy surface on cloth on which short fluff is thickly and uniformly formed. In this fluff-raising process there is no deterioration of the cloth such as undue heating of cloth or the cutting off of raised fibers. The method includes the conveying of the cloth between a working rotary member formed of a cylindrical grindstone and a pressure-contact member having a cooperating circular arc-shaped concave surface portion with which a part of a peripheral surface of the working rotary member is cooperatively engaged. The pressure-contact member is disposed in such a manner that the circular arc-shaped concave surface portion thereof faces closely to the adjacent part of the peripheral surface of the working rotary member. A hydraulic pressure is applied from the circular arc-shaped concave side of the pressure-contact member to the cloth, while the cloth is conveyed by rotation of the working rotary member, so that the cloth is brought into close contact with the peripheral surface of the working rotary member.
