14 Claims

1. A brush comprising a support (12) made of a plastically deformable plastic material for disposing bristle clusters (13) thereon, the support (12) having a plurality of cluster holes (14) each serving to accommodate one bristle cluster (13), the bristle clusters (13) each being fixed in a cluster hole (14) by means of clips (16, 40) having a length l greater than a diameter D of the cluster hole (14) so as to form clip projections (23, 24) formed on both longitudinal ends (37, 38), and the clips (16, 40) being provided with discontinuous structural elements (30, 42) at least in an area of the clip projections (23, 24) on at least one longitudinal side (21, 22; 43, 44) disposed essentially parallel to a cluster hole axis, the clip projections (23, 24) provided with the structural elements (30, 42) being pressed into and thereby embedded in the plastic material of the support (12) so as to fix the bristle clusters (13), wherein the structural elements (30, 42) are disposed at a distance to the longitudinal edges (18, 46, 47) of the clips (16, 40), wherein the structural elements (30, 42) have both a valley (35, 47) and a peak (36, 48) relative to a base surface (50, 49) of the longitudinal side (21, 22; 43, 44), wherein the valley (35, 47) at least partially surrounds the peak (36, 48).
