  • Patent number: 4648249
    Abstract: A needle selecting arrangement for a knitting machine with a knitting and stitching transmitting cam and a plurality of electromagnetic selecting elements, the arrangement comprises a plurality of spring biased needles each having a needle shaft; comprising at least one switchable displacement cam part arranged to move in front of the knitting and stitching transferring cam; a plate cover having a lower edge and a plurality of openings which are arranged in a stepped manner in association with the selecting elements and normal to a needle bed plane; an arresting rail provided with a plurality of grooves; a plurality of plates having a first side which faces toward the needles and provided at the first side with a substantially spherical end arranged to abut against the needle shaft and with a plate foot cooperating with the displacement cam part, each of the plates having an opposite second side which is fork-shaped and is provided with cam projections for tensioning against the lower edge of the plate cover

  • Patent number: 4283926
    Abstract: The flat knitting machine having two pairs of consecutively arranged needle beds and a plurality of knit carriages circulating in one direction above the needle beds and each supporting adjustable control bars cooperating with stationary control plates arranged between the pairs of needle beds, includes a control device for controlling the position of the control bars by means of a plurality of parallel tracks formed in respective control plates to guide the assigned control bar in a plurality of control positions. The ends of respective tracks are arranged in different consecutively arranged sections and each section movably supports a pair of switching flaps or guides activated by separate control members. The control guides in each section are activated simultaneously and independently from one another so that when the advancing control bars leaves one section the latter is ready for readjustment according to the desired position of the control bar in the subsequent carriage.

  • Patent number: 4154067
    Abstract: A knitting machine is comprised of a first pair of cooperating flat needle beds and a second pair of cooperating flat needle beds positioned behind the first. Cam slides are provided with cams for controlling the motions of the needles in the needle beds. The cam slides are mounted for travel in a single direction along a closed path extending around the two pairs of needle beds. At least one, but preferably all, of the cam slides is provided with cam arrangements capable of causing needles to perform normal-knitting motion, loop-delivery motion for loop transfer and also loop-acceptance motion for loop transfer. As the cam slide makes one trip in one direction along one pair of needle beds, it can cause loops to be transferred in both directions during the single trip. When a switchover to normal knitting is to be made, the cam slide need not be replaced but is merely reset for normal knitting.
