  • Patent number: 11891734
    Abstract: A compound needle (13) for knitting machines, which is optimised in respect of stiffness, strength and service life and whose needle (1) has at least one hole (7) with which a functional element (8) of the slider (2) engages when the slider (2) is in its working portion (24). The functional element (8) connects operatively in such a way with the hole (7) in the needle (1) that it limits the freedom of movement of the slider (2) relative to the needle (1) to the slider's working portion (24)—i.e. prevents the slider from leaving the working portion (24) at the position of the functional element (8).

  • Patent number: 11725313
    Abstract: A method and a knitting device for plating with compound needles on a circular knitting machine is described herein. At least two yarns are inserted into the hook area of a compound needle. A sinker is moved in such a way relative to a knock-over edge disposed immovably on a cylinder that the sinker, by way of a guide means, guides at least one of the yarns further into the hook area of the compound needle, in the direction of the needle shank, and in doing so keeps the yarns separated. The sinker furthermore moves, in the longitudinal direction and the elevational direction, in such a manner relative to the knock-over edge that the guide means performs a movement which, at least section-wise, tracks at least one yarn.

  • Patent number: 11668029
    Abstract: A device and a method for handling weaving accessories are described herein. The device comprises at least one holding element for a weaving accessory. The at least one holding element comprises a contact surface for a weaving accessory. The greater extension of the contact surface defines the longitudinal direction of the holding element and the lesser extension of the contact surface defines the lateral direction of the holding element. The at least one holding element is arranged pivotably around a first axis, which extends at a right angle to the holding element's longitudinal direction. A weaving accessory at the holding element's contact surface can thus be moved from a pick-up position to a drawing-in position by pivoting the holding element around the first axis.

  • Patent number: 11578436
    Abstract: A knitting machine part comprises a plurality of tool guides, each for one knitting tool. Each tool guide has a hardened region. The majority of the hardened regions are formed to be integral without seams or joints which transition integrally into adjacent, non-hardened regions. At least one hardened region of the knitting machine part is formed by a non-integral region, in that a hardened, separate component is arranged there, which forms the non-integral hardened region. The component can be designed as an insert part and inserted in a receptacle recess. The integral regions are preferably formed by induction hardening of a knitting machine part which is not yet hardened, wherein a separate hardened component can be arranged in each insufficiently hardened region in order to provide a hardened, non-integral region.

  • Patent number: 11464267
    Abstract: A device (40) and a method is described for handling fragments (10) of a broken needle (11), for example in the context of a needle exchange of a broken needle (11) for a new needle (17). The fragments (10) of the broken needle (11) are arranged in a container (16) in a predetermined position. An image (32) of the fragments (10) of the broken needle (11) is then recorded with the aid of a camera (23). The recorded image (32) is stored for documentation (32) at at least one storage location and/or analysed as to whether all the fragments (10) of the broken needle (11) are present. After recording the image (32), the container (16) is closed in order to avoid the fragments (10) of the needle (11) being lost away from the sewing workstation.

  • Patent number: 11414792
    Abstract: In the method according to the invention, a wire (11) provided with teeth (15) passes sequentially through a first inductor (16) and a second inductor (18). The inductors (16, 18) function at different frequencies and generate different temperatures. The first inductor (16) heats in particular the base section (17), which is not to be hardened, to a high temperature below the austenitizing temperature range. The second inductor (18) heats the teeth (15) to a still higher second temperature within the austenitizing temperature range. Defined, hardened teeth of consistently high quality result at quenching.

  • Patent number: 11203824
    Abstract: A machine knitting tool and in particular a machine knitting needle has a shank extending in the longitudinal direction. The machine knitting tool has a stitch-forming portion directly adjacently to a front end and a drive portion directly adjacently to a rear end. At least in the drive portion, an underside of the shank does not have any indentations or recesses and extends along a plane. The shank in the drive portion forms at least one rib portion with a rib height, which is at most 1.1 mm. In addition, the shank in the drive portion forms at least one support elevation, which extends in the height direction beyond the rib height of the at least one rib portion and has an elevation height at its point of maximum height.

  • Patent number: 11028513
    Abstract: A handling unit (10) comprises a loop gripper module (11) and a clamping device (12), which has a frictionally engaged connection with the sliders (24-33) of the loop gripper module (11). The sliders (24-33) are lightly clamped in corresponding slots of the clamping device and cannot, even if shaken, slip against one another and in particular they also cannot slide out of the loop gripper module (11). Thus, the sliders are all at the same position, and need not be moved back by hand during mounting. For example, in order to remove clamping device, which is in the form of a plastic clip, the clamping device need only be pressed onto the loop gripper module or be pulled away from the loop gripper module. When this force is applied, the plastic clip is lifted from the sliders (24-33) in a rotating movement.

  • Patent number: 10988863
    Abstract: A card wire has consecutive teeth spaced apart in the longitudinal direction by a pitch. The teeth are bounded in the longitudinal direction by a tooth face on a first side and by a tooth back on a second side. Looking downwards in the height direction of the card wire, the tooth face and the tooth back of consecutive teeth merge in a tooth base and, looking upwards in the height direction, form a tooth tip. The tooth depth is defined by the greatest distance, in the height direction of the card wire, from the tooth tip to the tooth base. The ratio of pitch to tooth depth is less than 1.1. An interspace, measured at right angles to a tangent to an inflection point between tooth back and tooth base, between this inflection point and the opposite tooth face is greater than a quarter of the pitch.

  • Patent number: 10934642
    Abstract: A loop-forming process includes moving a plurality of system components (11, 12) relatively to a needle bed (14). The system components (11, 12) contact threads (23) for forming loops. At least one spacer (10) is placed between at least two adjacent system components (11, 12) of the plurality of system components (11, 12) and defines the distance (21) between the two adjacent system components (11, 12), the spacer (10) being in mechanical contact to the two adjacent system components (11,12). The spacer (10) is placed away from and does not contact threads (23) and is moved with respect to the needle bed (14). The spacer (10) is also moved with respect to both of the two adjacent system components (11, 12) at least for a period of time during the loop forming process. An equivalent device is also disclosed and claimed.
