Device for removing needles from a fabric web

Abstract

At the outlet end (B) of a tentering frame ( 1 ), on the side of the tentering frame chains with needle plates ( 3 ) there are transport means ( 11 ) in the shape of conveyor belts ( 19 ) and clamping bands ( 23 ), whose runs ( 19′, 23 ′) intersect the plane (E) formed by the tentering frame chains ( 3 ) at an acute angle (alpha) at a point (X). The needles are removed from the fabric web ( 39 ) which is guided in a clamped way during the needle removal by the conveyor belts ( 19 ) and clamping bands ( 23 ).

1 . Device for removing needles from a fabric web ( 39 ) in a tentering frame ( 1 ), comprising two tentering frame chains ( 3 ), which carry the fabric web ( 39 ) on longitudinal edges thereof and which transport and hold the fabric web ( 39 ) in tension perpendicular to a transport direction (T) between a web receiving point (A) and a web outlet point (B), at the web outlet point (B) at a side of the tentering frame chains ( 3 ) there is at least one conveyor belt ( 19 ) having a first segment ( 19 ′) that intersects the transport plane (E) of the tentering frame chains ( 3 ) at an angle (alpha).  
   
   
       2 . Device according to  claim 1 , wherein a second segment ( 19 ″) of the at least one conveyor belt ( 19 ) lies at an acute angle to the first segment ( 19 ′) and extends past the web outlet point (B).  
   
   
       3 . Device according to  claim 1 , wherein over the at least one conveyor belt ( 19 ) there is a clamping band ( 23 ) having a lower run ( 23 ′) that lies opposite the first segment ( 19 ′) of the conveyor belt ( 19 ), which forms an upper run.  
   
   
       4 . Device according to  claim 1 , wherein there are at least two of the conveyor belts ( 19 ) that are arranged at an acute angle (beta) to the tentering frame chains ( 3 ).  
   
   
       5 . Device according to  claim 1 , wherein the tentering frame chains ( 3 ) and the at least one conveyor belt ( 19 ) can be driven independently and at the same and different speeds.
