Abstract (en)
To produce scouring pads and the like a stencil 11 is pressed against an open-cell foam sheet 10 so that the foam projects through holes 12 in the stencil, a hardenable resin is applied and upon removal of the stencil and hardening of the resin forms dots embedded in the surface. The foam can be laminated to a fabric backing and the dots may be bonded to the backing. A thin thermoplastic film on the working surface allows use of weak foam material without interfering too much with the abrasive action.
