Patent number: 7584769Abstract: A method for the insertion of a weft thread into a shed of a rapier weaving machine is presented in which the weft thread (3) is taken up by a bringer rapier (10) and fixedly clamped in the same by means of a thread clamp, is inserted into the shed by means of the bringer rapier and is taken up by a taker rapier. In the said method the clamping force of the thread clamp in the bringer rapier is additionally controlled during the weft insertion in such a way that the clamping force (F0) during the take-up of the weft thread and/or during the transfer of the weft thread is reduced relative to the clamping force (F1) in the insertion phase lying therebetween.Type: GrantFiled: October 29, 2007Date of Patent: September 8, 2009Assignee: Sultex AGInventors: Remo D'Incau, Marius Bachofen, Davide Maccabruni

Patent number: 7543610Abstract: A thread clamp for a rapier head (1) is presented which contains a clamping part (4) for firmly clamping a weft thread (3) and an actuator (5) for moving the clamping part (4). The actuator (5) includes a ferromagnetic core (12), an armature (11) and at least one winding (13) which is arranged on the core or armature in order to produce a magnetic field in the latter and to move the armature and the clamping part, which is operatively connected to the latter, with the core (12) having two limbs (12.1, 12.2) between which the armature (11) is movably arranged, and with each limb being provided with a permanent magnet (14.1, 14.2) in order to hold the armature at one of the two rest positions in the current-free state of the winding.Type: GrantFiled: June 11, 2007Date of Patent: June 9, 2009Assignee: Sultex AGInventors: Erich Kläui, Marius Bachofen, Dietmar Markward

Publication number: 20090065090Abstract: A thread clamp for a rapier head (10) for the firm clamping of weft threads (2, 2?, 2?, 2??) in a rapier weaving machine is presented. The thread clamp (1) has first and second holding members (3, 4) which can be pressed against one another in a clamping region (3a, 4a) in order to hold the weft threads. Moreover, one or more deflection elements (7, 7?) are provided at the thread clamp in order to deflect the weft thread or threads (2, 2?, 2?, 2??) and to increase the holding force, with at least one deflection element (7, 7?) being controllable.Type: ApplicationFiled: September 11, 2008Publication date: March 12, 2009Applicant: Sultex AGInventors: Marius Bachofen, Remo D'Incau, Robert Ruegg

Publication number: 20080018176Abstract: A power supply for a rapier head (1) of a rapier weaving machine, which is connected to a rapier bar which can be displaced in the longitudinal direction or to a band (2) which can be displaced in the longitudinal direction, is presented. The power supply includes an inductive coupling device with at least one primary induction coil (8) and with at least one secondary induction coil (9) which can be inductively coupled to the primary induction coil, with the secondary induction coil (9) being formed on the rapier bar or on the band (2) respectively.Type: ApplicationFiled: May 8, 2007Publication date: January 24, 2008Applicant: Sultex AGInventors: Dietmar Markward, Marius Bachofen, Erich Klaeui
