  • Patent number: 5560228
    Abstract: In a textile machine, in particular in a knitting machine, with controlla working elements and an arrangement for selecting the working elements, the working elements are held in their initial position by a holding magnet and are selectively released from their initial position by an electromagnetic control system. In order to obtain a textile machine with a simple design, capable of being driven at high working speeds but in a reliable and safe manner, at least one holding magnet is rigidly fixed to the part of the textile machine that carries the working elements. A direct contact between the working elements and the moving control system is thus avoided, so that a contactless selection of the working elements is made possible.

  • Patent number: 5201198
    Abstract: A slider needle for knitting machines has a needle body (1) with a hook (2), a slider (3) arranged to move in the needle body (1) and a swinging member articulated on the needle body (1) behind the hook (2). To avoid excessive travel when forming a stitch and to ensure the separation between the old stitch and the strand newly fed in, there is a spring (10) in the needle body which causes the swinging the member (4) to move away from the hook (2) so that one lateral edge (7) of the swinging member (4) is almost vertical.

  • Patent number: 4679412
    Abstract: In a method of determining and correcting the length of a piece of knitting eing produced on an electronically controlled flat knitting machine, the particular length of the piece of knitting which is being produced is continuously monitored by means of a sensor which supplies a value for the determined actual length to a control circuit where the value is compared with an instantaneous, programmed desired length value, and the determined real length value and the result of the comparison are used to control the stitch length in the following courses and/or the shape and/or type of knitting and pattern of the rest of the piece of knitting. by this means it is possible to produce constant-length pieces of knitting of the same shape, independently of changes in the technical knitting parameters, and controlled by the determination of the relevant actual knitted length of the piece of knitting.

  • Patent number: 4448045
    Abstract: A slider needle for knitting machines, particularly flat knitting machines, omprises a needle body with needle hook and at least one needle butt, and a slider equipped with slider foot and mounted to be displaceable relative to the needle body. In order to ensure trouble-free and reliable separation of the old stitches from newly laid yarn a short swivel detent is mounted on the needle body behind the needle hook. The length and shape of this swivel element is chosen so that in the normal position of the needle, with the needle hook closed by the slider, the swivel detent is masked by the slider in the vertical direction, while when the needle hook is open the swivel detent projects proud of the needle body and above the slider in both its end positions.
