Abstract
Individual tufts of bristles are picked from a supply of pre-cut bristles having rounded utilization-side ends and transferred to a vise. The vise has a number of through holes arranged in a pattern corresponding to that of the tufts on the finished tooth brushes. While tufts of bristles are held in the through holes of the vise with their ends projecting on both sides, a die member having a profiled face is advanced into engagement with the ends of the bristles to move them axially through the holes of the vise and with respect to each other until both ends of the bristles are aligned in parallel planes corresponding in shape to that of the profiled face. The tufts of bristles are now clamped in the vise and transferred to the brush body head to be implanted therein.
