Method for manufacturing wiper rubber part for windshield wiper of glass pane of vehicle, involves providing wiping rubber extrusion, and introducing particles into portions of wiping rubber extrusion through fabric strips

摘要

The method involves providing a wiping rubber extrusion (1) in form of a strand with a wiping lip portion and a mounting portion. Particles (5) e.g. thermoplastic polymer particles and/or sliding friction-lowering particles, are introduced into portions (2c, 2c') of the wiping rubber extrusion through fabric strips (21, 21') provided with the particles. The particles are held in stitches of the fabric strips. Pressure (p) is exerted on the fabric strips and the portions of the rubber extrusion. The pressure is exerted by pressing rollers (22, 22') e.g. pressing rolling system. Independent claims are also included for the following: (1) a wiper rubber part (2) a windshield wiper.
