Patent number: 7178560Abstract: A device for inserting weft threads in an airjet weaving machine including at least one main blower and a respective thread clamp associated with the main blower. The thread clamp is constituted of an element configured in a modular form. Such modular form enables several such elements to be assembled in a modular configuration, including one on top of another. Pneumatically actuated elements are used to engage and disengage the thread clamps whereby the thread clamps may be engaged or disengaged by pressure and vacuum supplied through a single supply conduit. A method for inserting weft threads in the shed of an airjet weaving machine includes holding each weft thread at least temporarily in a thread clamp that moves with the sley of the weaving machine and using a thread tensioner outside the shed at a location between the thread supply and the thread clamp.Type: GrantFiled: May 17, 2002Date of Patent: February 20, 2007Assignee: Picanol N.V., naamloze vennootschapInventors: Jean Marie Bamelis, Chris Delanote, Jozef Peeters, Herman Salomez
