Inserting rapier for a rapier weaving machine

Abstract

An inserting rapier ( 1 ) for a rapier weaving machine with a thread clamp ( 4 ) for the firm clamping of a weft thread ( 3 ) is presented, with the inserting rapier also including a guiding or holding device ( 10 ) with a guiding or holding element ( 5 ) and a mass ( 6 ) which are movably arranged on the inserting rapier and with the guiding or holding element ( 5 ) being movable by means of the inertia of the mass ( 6 ) in order to guide or hold the weft thread.

1 . Inserting rapier for a rapier weaving machine with a thread clamp ( 4 ) for the firm clamping of at least one weft thread ( 3 ), characterized in that the inserting rapier ( 1 ) also includes a guiding and/or holding device ( 10 ) for guiding and/or holding the weft thread with a guiding and/or holding element ( 5 ) and a mass ( 6 ); and in that the guiding and/or holding element ( 5 ) can be controlled and/or moved by means of inertial forces which act on the mass ( 6 ) during an acceleration or deceleration of the inserting rapier.  
   
   
       2 . Inserting rapier in accordance with  claim 1 , with the guiding and/or holding element ( 5 ) and/or the mass ( 6 ) being movably mounted on the inserting rapier ( 1 ).  
   
   
       3 . Inserting rapier in accordance with  claim 1 , with the thread clamp ( 4 ) and the guiding and/or holding element ( 5 ) being arranged spaced apart in order to be able to guide and/or to hold the weft thread ( 3 ) on transfer to a receiving rapier on both sides of the receiving rapier ( 2 ).  
   
   
       4 . Inserting rapier in accordance with  claim 2 , with the inserting rapier ( 1 ) including two side walls ( 1   a ,  1   b ) and with the thread clamp ( 4 ) being arranged in the vicinity of the one side wall and the guiding and/or holding element ( 5 ) being arranged in the vicinity of the other side wall.  
   
   
       5 . Inserting rapier in accordance with  claim 1 , with the guiding and/or holding element ( 5 ) being resiliently designed or mounted or being connected to a spring element, and with the mass ( 6 ) being arranged at the guiding and/or holding element ( 5 ).  
   
   
       6 . Inserting rapier in accordance with  claim 1 , with the guiding and/or holding element being designed as a movably journalled pawl ( 5 ) which can be moved by means of the inertia of its own mass.  
   
   
       7 . Inserting rapier in accordance with  claim 1 , with the guiding and/or holding element ( 5 ) being designed and arranged in such a manner that the weft thread ( 3 ) is held by the same in a notch ( 8 ) which is formed in the inserting rapier ( 1 ), in particular in an upper part ( 9 ) of the inserting rapier.  
   
   
       8 . Method for the guiding and holding of a weft thread in an inserting rapier, in said method the weft thread ( 3 ) being taken up by the inserting rapier ( 1 ) and being clamped in the latter by means of a thread clamp ( 4 ), characterized in that the weft thread is additionally guided and/or held in the inserting rapier by means of a guiding and/or holding device ( 10 ) which is controlled and/or moved by means of the inertia of a mass ( 6 ).  
   
   
       9 . Method in accordance with  claim 8 , with the guiding and/or holding device ( 10 ) being closed by the inertia of the mass ( 6 ) prior to reaching the transfer point, with the weft thread ( 3 ) extending between the thread clamp ( 4 ) and the guiding and/or holding device ( 10 ) on reaching the transfer point, and with a receiving rapier ( 2 ) taking over the weft thread which extends between the thread clamp and the guiding and/or holding device.  
   
   
       10 . Rapier weaving machine including an inserting rapier in accordance with  claim 1 .  
   
   
       11 . Rapier weaving machine equipped for carrying out a method in accordance with  claim 8.
