  • Patent number: 5678501
    Abstract: A linking machine in which three stepper motors are provided which adjust the opening width between the two rails of a conveyor, the height of the rails of the conveyor, and the vertical position of an edge trimmer with respect to the plane of transport of the socks. The stepper motors are actuated by drivers from a microprocessor which, in its turn, can be controlled via a keyboard. The keyboard is connected with a display which displays the data of each individual adjustment as well as the data of the program selected.

  • Patent number: 5513782
    Abstract: A device for a stocking turning machine for automatically separating only partially turned stockings from completely turned stockings.Each stocking which leaves the automatic stocking turning machine is conducted by a chute into a pneumatically operating ejection tube which bears two photocells with corresponding reflectors. The adjustable distance between the two photocells is such that when the stocking in question has been completely turned, its toe and the stocking welt simultaneously darken the two photocells. A cylinder is then actuated in such a manner that a guide chute which is connected to it assumes a deflection position shown in solid lines in the drawing, whereby the stocking falls into the container, whereupon the guide chute again returns into its starting position.

  • Patent number: 5415330
    Abstract: A feeder for guiding stockings in a looping machine includes a mechanism for rapid adjustment of the opening width between two mutually facing guide bars provided with two horizontal mutually parallel rods loaded by respective springs pressing the rods against an actuating element mounted rotatably about a horizontal axis running perpendicular to the rods and provided with an angularly displaceable grip for displacing the rods and one of the guide bars connected fixedly therewith toward and away from the other guide bar.

  • Patent number: 5398626
    Abstract: A chain feeder for a looping machine for closing a toe portion of a stocking formed of elastic yarns includes two identical bars forming a slot therebetween for receiving a folded toe portion of the stocking to be sewn, each bar having a first segment starting at a distance after an inlet of the feeder and diverging downwards and passing into a second segment running parallel to the upper side of the bar, so that the first segments of the bars form a slanted plane interrupted by a slot receiving the stockings in which the finer rows of elastic yarn at the toe portion are gradually stretched upon advancing along the slot.

  • Patent number: 4509666
    Abstract: A stocking turning device comprises a pair of belts (9, 10) of a lower pair, which grip the toe of a previously-sewn stocking having an indent or pocket at its closed end, and fit it on to a flat bar or batten (6) disposed vertically. The belts (11, 12) of an upper pair stop immediately the free edge of the stocking top is no longer grasped by the lower pair of belts.

  • Patent number: RE29492
    Abstract: In order to allow the so called "casual" impaling of the edges of the binding strip and of the knit-wear article on the points of the rotary dial of a linking machine, the strip is formed at its opposite longitudinal edges with tabs which are superimposed on the inner face of the binding strip before the latter is bent to channel shape. Thicker end portions are formed on the free longitudinal edges of said tabs in order to permit semi-automatic impaling of the binding strip onto the points using guides provided with through slots directed towards the annular path of the points. A further guide allowing a semi-automatic impaling of the article edge to be sewn to the binding strip, may be also provided.
