The roller leather of the traditional computer flat knitting machine will have the problem of excessive tension and hair breakage during weaving, especially when weaving yarns with insufficient strength such as cashmere, the hair breakage is more serious. The existing roller leather will have a functional groove on the outer surface to achieve the purpose of releasing tension. The working principle of the existing roller leather is as follows: when the two rollers rotate relative to each other, the surfaces of the two roller leather bodies rotate relative to each other to pull the fabric normally; when the functional groove is opposite to the surface of the roller leather body, part of the traction force is released on the fabric; when the functional groove is opposite to the functional groove, the traction force on the fabric is released. The roller leather body continues to rotate, and different parts are periodically opposite to each other, so that the traction force of the roller on the fabric is kept within a certain range, thereby solving the problem of excessive traction force of the existing roller leather on the fabric.
