  • Patent number: 11668028
    Abstract: A device and a method for handling of weaving accessories are disclosed. The device has a first holding element and at least one further holding element for weaving accessories. The first holding element and the at least one further holding element are provided for being moved cyclically between a supply device and a receiving device. At least the first holding element is configured to complete at least part of its movement between the supply device and the receiving device while the at least one further holding element remains stationary.

  • 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: 11512414
    Abstract: A method and a device for the automated transport of weaving accessories is disclosed. A device is provided which has at least one rail and at least one rail carrier. The at least one rail carrier carries the weight of the at least one rail, on which weaving accessories can be movably disposed in the longitudinal direction of the rail. The method is characterized in that the at least one rail carrier is displaced relative to the at least one rail, in the longitudinal direction thereof, in order to move weaving accessories disposed at the rail along the rail in the longitudinal direction thereof.

  • Publication number: 20080135121
    Abstract: The shaft rod in accordance with the invention consists of only one (steel) metal sheet which is essentially configured without a large hollow chamber. The metal sheet has two stiffening means which are preferably located at the top and at the bottom of the shaft rod and are configured as edges. Preferably, the upper stiffening means (10) is implemented in the configuration of a small hollow chamber or of a solid reinforcement. The lower stiffening means (11) is implemented by attaching the heald support rail. Attachment may occur in accordance with any joining method, such as, for example, welding, cementing, clinching. The shaft rod may be manufactured by shape-rolling or roll-forming, as well as by all other reforming processes that are suitable for metal sheets. It is preferred that the heald support rail be directly integrated in the sheet metal form of the shaft rod. As a result, the entire shaft rod consists of a single metal sheet.
