Traversing thread guide

Abstract

The invention relates to a traversing thread guide for causing a thread to traverse at a workstation of a textile machine that produces cross-wound packages, comprising a base carrier, which can be arranged on a traversing rod, and a thread-guiding element, which is arranged on the base carrier and which has two wall portions, which are arranged at a distance from each other and delimit a thread insertion slot and a thread-guiding channel.

1 . A traversing thread guide ( 1 ) for causing a thread ( 24 ) to traverse at a workstation of a textile machine that produces cross-wound packages, comprising:
 a base carrier ( 4 ), configured to be arranged on a traversing rod ( 21 ); and   a thread-guiding element ( 3 ), arranged on the base carrier ( 4 ), comprising two wall portions ( 7 ,  8 ), which are arranged at a distance from each other and are configured to delimit a thread insertion slot ( 2 ) and a thread-guiding channel ( 5 ),   wherein each of the wall portions ( 7 ,  8 ) comprises, on its top facing away from a base surface ( 16 ) of the thread-guiding element ( 3 ), a support surface ( 9 ) formed by a plane.   
     
     
         2 . The traversing thread guide ( 1 ) according to  claim 1 , wherein the support surfaces ( 9 ) are arranged in a common plane. 
     
     
         3 . The traversing thread guide ( 1 ) according to  claim 1 , wherein the support surfaces ( 9 ) are oriented parallel to the base surface ( 16 ). 
     
     
         4 . The traversing thread guide ( 1 ) according to  claim 1 , wherein the support surfaces ( 9 ) are inclined relative to each other and/or toward an end face ( 13 ) of the thread-guiding element ( 3 ). 
     
     
         5 . The traversing thread guide ( 1 )  claim 1 , wherein the planes of the support surfaces ( 9 ) intersect at an angle of more than 140°. 
     
     
         6 . The traversing thread guide ( 1 ) according to  claim 1 , wherein tops of the wall portions ( 7 ,  8 ) are rounded in a region of their inner edges ( 20 ), front edges ( 10 ), side edges ( 15 ), secondary edges ( 19 ) and/or rear edges ( 11 ). 
     
     
         7 . The traversing thread guide ( 1 ) according to  claim 1 , wherein the wall portions ( 7 ,  8 ) each comprise, in a region between the support surfaces ( 9 ) and a side surface ( 12 ), a lateral transition portion ( 18 ) which drops toward the side surface ( 12 ). 
     
     
         8 . The traversing thread guide ( 1 ) according to  claim 1 , wherein the wall portions ( 7 ,  8 ) have, in a region between an end face ( 13 ) and a side surface ( 12 ), front transition portions ( 17 ) which taper the thread-guiding element ( 3 ) toward the end face ( 13 ). 
     
     
         9 . The traversing thread guide ( 1 ) according to  claim 1 , wherein the thread-guiding element ( 3 ) is detachably connected to the base carrier ( 4 ). 
     
     
         10 . The traversing thread guide ( 1 ) according  claim 1 , wherein rear edges ( 11 ) and the inner edges ( 20 ) of the wall portions ( 7 ,  8 ) are connected to each other in a rounded manner. 
     
     
         11 . The traversing thread guide ( 1 ) according to  claim 1 , wherein tops of the wall portions ( 7 ,  8 ) comprise, in a region between a rear edge ( 11 ) and the support surface ( 9 ), a rear transition portion ( 14 ) inclined toward the base surface ( 16 ). 
     
     
         12 . The traversing thread guide ( 1 ) according to  claim 1 , wherein an end face ( 13 ) of the thread-guiding element ( 3 ) is positioned at an angle of 75° to 90° to the base surface ( 16 ). 
     
     
         13 . The traversing thread guide ( 1 ) according to  claim 1 , wherein an end face ( 13 ) of the thread-guiding element ( 3 ) is positioned at an angle of 80° to the base surface ( 16 ). 
     
     
         14 . The traversing thread guide ( 1 ) according to  claim 1 , wherein the planes of the support surfaces ( 9 ) intersect at an angle of more than 160°. 
     
     
         15 . The traversing thread guide ( 1 ) according to  claim 1 , wherein the planes of the support surfaces ( 9 ) intersect at an angle of 175° to 195°.
