Automatic wasteless transfer winding apparatus

Claim 1

An automatic wasteless transfer precision winder apparatus for winding up continuously advancing yarn, said apparatus comprising: a. a pair of spaced chucks with pirns operatively mounted and connected to independent drive means for rotating said pirns, b. guide means for guiding the yarn to one of said pair of pirns, c. automatic movable transfer yarn means comprising a pair of transfer arms for alternately transferring the yarn from a full pirn to an empty pirn, each arm having a rotatively adjustable collar with a peripherally protruding lug guide means nearer one end of each transfer arm, and a cone-shaped guide means nearer the opposite end of each transfer arm, means for moving said transfer arm whereby said cone-shaped guide means intersects the path of yarn movement for alternate transfer of the yarn from the full pirn to the empty pirn upon a predetermined length of yarn being wound on the full pirn, said protruding lug guide means being so positioned as to control the length of a transfer tail upon transfer of the advancing yarn from said full pirn, a severing means for severing said advancing yarn upon transfer of yarn from said full pirn to said empty pirn, and d. automatically electrically sequencing circuitry means for interrelating said advancing yarn with said drive means and said yarn transfer means.
