Method and knitting device for plating on a circular knitting machine equipped with compound needles
Patent number: 11725313Abstract: 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.Type: GrantFiled: May 28, 2020Date of Patent: August 15, 2023Assignee: Groz-Beckert KGInventors: Martin Wörnle, Roland Simmendinger -

Patent number: 11668029Abstract: 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.Type: GrantFiled: June 15, 2020Date of Patent: June 6, 2023Assignee: GROZ-BECKERT KGInventors: Christian Gerth, Stefan Kailer, Bernd Pfeffer, Michael Acker, Karl-Heinz Gesing

Patent number: 11578436Abstract: 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.Type: GrantFiled: January 31, 2019Date of Patent: February 14, 2023Assignee: GROZ-BECKERT KGInventors: Rainer Krauss, Markus Settegast

Patent number: 11414792Abstract: 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.Type: GrantFiled: May 5, 2015Date of Patent: August 16, 2022Assignee: Groz-Beckert KGInventors: Johannes Bruske, Peter Meinert, Carmen Goltermann, Bernd Binder

Patent number: 11203824Abstract: 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.Type: GrantFiled: June 15, 2018Date of Patent: December 21, 2021Assignee: Groz-Beckert KGInventor: Uwe Stingel

Patent number: 11028513Abstract: 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.Type: GrantFiled: March 14, 2019Date of Patent: June 8, 2021Assignee: Groz-Beckert KGInventors: Marius Pintea, Manuel Wienen

Patent number: 10988863Abstract: 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.Type: GrantFiled: October 19, 2018Date of Patent: April 27, 2021Assignee: Groz-Beckert KGInventors: Peter Heißel, Stefan Lohrmann

Patent number: 10934642Abstract: 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.Type: GrantFiled: July 7, 2016Date of Patent: March 2, 2021Assignee: Groz-Beckert KGInventors: Martin Wörnle, Jörg Sauter, Uwe Stingel, Eric Jürgens, Hans-Jürgen Haug, Marco Andreoli, Stefano Rizzi
