Abstract
A circular ladies hosiery knitting machine is provided having a conventional rotatable needle cylinder and dial. The dial includes radially movable transfer jacks which, when fully extended, cooperate with the needles to form loops on the jacks. A selectively operable device positions a de-looper element in the path of loops carried by the transfer jacks whereby the loops are lifted out of engagement with the jacks without the jacks having to be retracted.
Claims3
An apparatus for terrying yarn comprising:
- a circular ladies hosiery knitting machine including:
- (a) a latch needle cylinder and a dial rotatable about a common axis;
- (b) a plurality of latch needles supported by said cylinder and movable therewith as the cylinder rotates, said needles being adapted to be reciprocated in a direction parallel to said axis to knit yarn into a fabric;
- and
- (c) a plurality of transfer jacks radially oriented with respect to said dial and movable therewith as the dial rotates, said jacks being adapted to be extended and retracted with respect to the dial in a plane normal to the direction of reciprocation of said needles, said jacks, when extended, cooperating with the needles to form loops of yarn on the jacks, said loops being movable in a circular path as the jacks rotate with the dial;
- and
- a de-looping arrangement adapted to be moved between operative and inoperative positions, said arrangement in the operative position being located in the path of movement of the loops carried by said extended jacks thereby engaging said loops to separate them from the jacks and said arrangement in the inoperative position being located out of the path of movement of the loops carried by said extended jacks thereby permitting said loops to be knitted into the fabric.
