  • 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.

  • Patent number: 10753024
    Abstract: A sewing machine needle includes a blade extending substantially in the needle's longitudinal direction, an eye, which passes through the needle substantially in its elevational direction, and a scarf, which extends along the needle behind the eye. Compared with the contour of the blade, the scarf contour is recessed in the needle's elevational direction. At least in part of the scarf's extension along the needle, the scarf contour in a sectional plane perpendicular to the needle's longitudinal direction is substantially an arc of a circle. The circular-arc-shaped area covers a first angular portion of the needle's circumference. In this part of the scarf's extension along the needle, the radius of the substantially circular-arc-shaped contour in this first angular portion of the needle's circumference is between 35% and 100% of the needle's maximum lateral reach. The needle's lateral direction is perpendicular to its longitudinal and elevational directions.

  • Patent number: 10731282
    Abstract: The invention relates to a gripper for a tufting machine, which has a gripper body and an insert. In the longitudinal direction, the gripper has a holding section and a guiding section. At the end further away from the holding section, in the longitudinal direction, the guiding section terminates in a hook which has an inner side in which a joint gap is arranged between the gripper body and the insert. According to the invention, the gripper is characterised in that a stop means, against which the insert abuts in the longitudinal direction towards the holding section, is arranged on the gripper body in the gripper's guiding section in order to limit the size of the joint gap in the inner side of the hook.

  • Patent number: 10487429
    Abstract: The tool (10) for textiles according to the invention consists of chromium steel, into which carbon has been embedded in locally varying amounts during a carbonizing process. Thermal treatment achieves a formation of martensite with the maximum achievable hardness, in particular in those zones in which larger carbon fractions have been introduced. A tool for textiles with zones of differing hardnesses can thus be produced without having to subject the individual zones with differing hardnesses to different process conditions during the production process. The hardness is controlled on the basis of the degree of deformation of the tool for textiles.

  • Patent number: 10190239
    Abstract: A textile part is configured for producing a composite-material element (11) or a composite-material body (12). The textile part (10) has a reinforcing system (15) including reinforcing warp threads (16) and reinforcing weft threads (17), and a binding system (25) with binding warp threads (27) and binding weft threads (26). The reinforcing system (15) has at least one first portion (20), into which the reinforcing threads (16, 17) are interwoven with one another directly for binding to facilitate withstanding high mechanical. The reinforcing system (15) also has at least one second portion (21), in which the reinforcing threads (16, 17) form binding-free crossover locations (22) preferably laid on one another in a drawn-out state to constitute a laid structure surrounded by the binding threads (26, 27). The laid structure of the reinforcing system (15), ensures particularly good draping and deformation capability at this location of the composite material.
