    Abstract: 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 thereof. 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 configurations are also disclosed.

    Abstract translation: 细长的研磨条形元件通过以一种锯齿状图案从该条带的一侧到另一侧前后缠绕研磨单丝或其捆,并将该链条拼接在单丝或其捆的相邻横截面上来制造。 所得的带材易于围绕横向轴线卷绕或卷绕,但是抵抗围绕纵向轴线的弯曲,由此可以容易地操作以形成各种构造的刷面。 用于生产链式线迹的经纱可以在能够被凸轮改变单丝纬纱的相邻横向股线之间的线圈数的针织机上制造,从而有选择地改变由单丝纬纱产生的刷面的密度 并且还可以改变研磨条本身的构型(即,以线形形式,圆形,截锥形等)。 条带的线性形式可以在其边缘的中间被切断以形成两个相同的刷毛条,每个可以以卷曲形式缠绕,例如,并且可以在一个侧面(例如通过模制)嵌入弹性体基部 以形成盘式刷。 还公开了其它刷子构造。
