<p>ABRASIVE BRUSHES AND METHODS OF MAKING SAME An elongate, abrasive strip element is produced by winding an abrasive monofilament, or bundles thereof, back and forth in a zigzag pattern from side to side of the strip, and chain stitching together adjacent transverse sections of the monofilament, or bundles therof. The resultant strip is easily rolled or coiled about a transverse axis, but resists bending about a longitudinal axis, whereby it can be manipulated readily to form brush faces of various configurations. The warp yarns which are used to produce the chain stitches may be produced on a knitting machine which can be cammed to vary the number of stitches between adjacent-transverse strands of the monofilament wefts, thereby selectively to vary the density of the brush faces produced from the strips, and also to vary the configuration of the abrasive strip itself (i.e to produce it in linear form, circular, truncated-conical, etc.). The linear form of the strip may be severed medially of its edges to form two, identical bristle strips, each of which may be wound in convolute form, for example, and may be embedded at one side (e.g. by molding) in an elastomeric base to form a disc type brush. Other brush conconfigurations are also disclosed.</p> |
