<p>Individual tufts of bristles are picked from a supply of pre-cut bristles having rounded utilization-side ends and transferred to a vice (24). The vice (24) 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 (10) are held in the through holes of the vice (24) with their ends projecting on both sides, a die member (26) having a profiled face (28) is advanced into engagement with the ends of the bristles to move them axially through the holes of the vice (24) 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 (28). The tufts of bristles (10) are now clamped in the vice (24) and transferred to the brush body head (22) to be implanted therein.</p> |
