Anchor rail with pull strip

Abstract

A filler for an anchor rail, including an elongated filling element and a tear strip for removing the filling element from a cavity of the anchor rail, the tear strip being joined to the filling element in a joining area. The tear strip is joined to the filling element with extra length in at least part of the joining area. An anchor rail with such a filler as well as a method for the production of such a filler are also provided.

1 . A filler for an anchor rail comprising:
 an elongated filling element; and   a tear strip for removing the filling element, the tear strip joined to the filling element in a joining area with extra length in at least part of the joining area.   
     
     
         2 . The filler as recited in  claim 1  wherein in the at least one part of the joining area the tear strip has a meandering layout along the filling element with a varying distance from the filling element. 
     
     
         3 . The filler as recited in  claim 1  wherein the tear strips glued to the filling element in the joining area. 
     
     
         4 . The filler as recited in  claim 1  wherein the filling element has an at least approximately flat surface in the joining area. 
     
     
         5 . An anchor rail castable into a component, the anchor rail comprising:
 a rail element having a cavity extending in a lengthwise direction; and   a filler as recited in  claim 1  being provided in the cavity.   
     
     
         6 . A method for the production of a filler having an elongated filling element and a tear strip for removing the filling element from a cavity of an anchor rail, the method comprising:
 joining the tear strip to the filling element in a joining area, the tear strip being joined to the filling element in at least part of the joining area so as to create an extra length in the tear strip.   
     
     
         7 . The method as recited in  claim 6  wherein the filling element is stretched to define a stretched area, at least partially, in a lengthwise direction, the tear strip being joined to the filling element in the stretched area. 
     
     
         8 . The method as recited in  claim 6  wherein the filling element is curved, at least in a curved area, the tear strip being joined to the filling element in the curved area. 
     
     
         9 . The method as recited in  claim 8  wherein the filling element is curved in a lengthwise direction over a roller to form the curved area. 
     
     
         10 . The method as recited in  claim 6  wherein the filling element is profiled, at least in a profiled area, the tear strip being joined to the filling element in the profiled area. 
     
     
         11 . The method as recited in  claim 11  wherein the profiled area is created by a toothed roller.
