| Abstract: |
A flexible and resilient abrading or detergent pad as a cleansing, scouring and smoothing or finishing device having a pervious and knitted outer covering of synthetic yarn and an engaging core of synthetic plastic sponge frictionally biased against the inner surfaces of the covering walls, the transverse edge areas of the covering and core being compressed and integrated for anchorage of the core to the covering. For manufacture, the sponge core is inserted into the sleeve, the assembly compressed and the transverse edge areas of both covering and core while under compression integrated or connected while under further compression at such areas. Trimming of the reduced and integrated or connected edges takes place following said procedures.

I claim:
1. A yieldable, compact, unitary, pervious, shape-retaining and flexible abrading pad comprising: a main compressed and resilient plastic sponge core body, said body being compressed throughout the full area thereof, and a pervious and abrasive plastic cover forming a tight-fitting against the walls of the said compressed and resilient sponge throughout the full respective areas thereof, said compressed and resilient sponge core body and said tight-fitting cover having corresponding transverse edge areas connected and reduced into strip form for anchorage connection to prevent shifting at such areas between said sponge core body and the cover when the pad is in use, the frictional connection between other areas of said sponge core body and said cover also preventing separation thereabout, said cover having top and bottom walls and connecting longitudinal edge areas formed of a continuous knit.
