Abstract
The present invention relates to a bristle finishing fork for isolating bristles affixed to a toothbrush head within a bristle finishing region comprising two elongated prongs having tips spaced at a distance 'A' defining the width of the bristle swath to be isolated, wherein starting at said tip, the distance between the prongs increases to a distance 'B' defining the sidewall of the bristle finishing region. The present invention still further relates to a device for isolating and end-rounding bristles affixed to a toothbrush head within a bristle finishing region comprising: (a) a means for holding a toothbrush with bristles affixed thereto; and (b) a bristle finishing fork comprising two elongated prongs having tips spaced at a distance 'A' defining the width of the bristle swath to be isolated, wherein starting at said tip, the distance between the blades increases to a distance 'B' defining the sidewall of the bristle finishing region, whereby said fork has a backwards and forwards motion, in such a way that the tip of said prongs can be introduced between toothbrush bristles through a parallel relative motion between fork and brush, so that the swath of bristles to be isolated are positioned in said bristle finishing region; and (c) a means for rounding the distal ends of the bristles positioned in said bristle finishing region.
