Method for producing seams on webbings for technical purposes

Abstract

In a method for producing seams on webbings for technical purposes, in particular on lifting straps or lashing straps for securing cargo during transport, a sewing thread is used to produce the seam, the fine strength of said sewing thread being significantly greater than the fine strength of the fibrous material or yam from which the webbing is produced. In this way, the binding load of a webbing having a seam is increased.

1 . A method for producing seams on webbings for technical purposes, characterized in that the stitching is effected using a sewing yarn having a tenacity which is significantly greater than the tenacity of the fiber material of which the webbing is made, more particularly is at least twice the tenacity of the fiber material of which the webbing is made. 
     
     
         2 . The method according to  claim 1 , characterized in that the tenacity of the sewing yarn is at least four times the tenacity of the fiber material of the webbing. 
     
     
         3 . The method according to either of the preceding claims, characterized in that the sewing yarn consists of highly oriented fibers composed of high molar mass linear polyethylene.
