Yarn tensioning device and arrays thereof

Abstract

Yarn tensioning devices and arrays thereof which supply a multiplicity of yarns at the same tension to a weaving loom without the tendency to pull-back, roll-back or forward loop are provided for the manufacture of carpets.

What is claimed is:  
     
         1 . A yarn tensioning device which supplies a multiplicity of yarns at the same tension and without tendency to roll-back to a loom, said yarn tensioning device comprising a frame with a sequence of apertures positioned along the frame wherein each aperture is equipped with a yarn braking assembly, said yarn braking assembly comprising a yarn holding platform with entry and exit conical bevels which forms the contact surface for the yarn and a braking element which interacts with the yarn holding platform and entry and exit bevels to control yarn tension.  
     
     
         2 . The yarn tensioning device of  claim 1  wherein the braking element comprises a spring member.  
     
     
         3 . An array of yarn tensioning devices comprising a plurality of yarn tensioning devices of  claim 1  laterally placed along the width of a warp of a weaving loom.
