US 4,049,006 A · Hair-weaving device

Abstract

A hair-weaving machine includes two endwise juxtaposed threaded shafts having a gap formed therebetween and two arms provided with grippers which may be rotated in a clockwise and anticlockwise directions around the shafts, respectively. As the arms are slowly advanced in the same directions longitudinally along the respective shafts, one arm with its gripper pushes a needle-attached thread through an endportion of a hairpiece and past a strand of hairs, while the other arm and its associated gripper grips the needle after the latter has been pushed through the endportion of the hairpiece and past the strand of hairs, and returns the needle and its associated thread subsequently to the first arm. The next action of the first gripper arm results in a complete loop being formed around the hairpiece endportion and the strand of natural hairs, subsequent loops being formed as the arms are advanced longitudinally along the respective shafts. A spool with a torsion spring attached to the frame of the machine keeps the thread tout at all times, which results in the formation of tight loops.

Dependent claims

A hair-weaving machine for attaching a hairpiece having an endportion to a strand of hairs comprising:

first holding means for gripping and forcing a needle having a thread attached thereto through the end portion of said hairpiece past the strand of hairs, the needle being releasable from said first holding means upon having been forced through said endportion of said hairpiece and past the strand of hairs;
second holding means for gripping the needle upon the latter having been forced through said endportion of said hairpiece and past the strand of hairs, and for guiding the needle to said first holding means, the needle being releasable from said second holding means upon being in the vicinity of said first holding means and grippable by the latter upon release from said second holding means;
and
thread-tension producing means for creating a tension in a needle-attached thread so that a tight loop of the thread is formed around at least part of said endportion of said hairpiece and at least part of the strand of hairs upon the needle being forced through the endportion of said hairpiece and past the strand of hairs at least a second time.
