Abstract

A tufting machine is configured with yarn drives having two spaced apart yarn bearing surfaces each substantially wrapped with a yarn and may have only half the needles and yarn drives customarily employed, with the needles being shifted to cover two gauge positions, thereby providing single and yarn control with reduced capital cost.

Claims

exact text as granted — not AI-modified
1 . A yarn feed for a tufting machine having a plurality of individually controlled yarn drive units with yarns being supplied from the rear of the yarn drive units to a face of the units and thence substantially about the circumference of both a first yarn drive gear surface and a second spaced apart yarn drive gear surface. 
     
     
         2 . The yarn feed of  claim 1  wherein 
     
     
         3 . The yarn feed of  claim 1  wherein 
     
     
         4 . The yarn feed of  claim 1  wherein 
     
     
         5 . The yarn feed of  claim 1  wherein 
     
     
         6 . The yarn feed of  claim 1  wherein 
     
     
         7 . The yarn feed of  claim 1  wherein 
     
     
         8 . The yarn feed of  claim 1  wherein 
     
     
         9 . The yarn feed of  claim 1  wherein 
     
     
         10 . The yarn feed of  claim 1  wherein 
     
     
         11 . The yarn feed of  claim 1  wherein 
     
     
         12 . The yarn feed of  claim 1  wherein 
     
     
         13 . The yarn feed of  claim 1  wherein 
     
     
         14 . A method of operating a tufting machine having a yarn feed of  claim 1  wherein the tufting machine is configured with loopers on gauge and needles spaced on double gauge and the backing fabric is fed at half speed while the needles are shifted to sew two laterally spaced stitches in the longitudinal length of one row. 
     
     
         15 . The method of operating a tufting machine of  claim 14  wherein 
     
     
         16 . The method of operating a tufting machine of  claim 14  wherein 
     
     
         17 . The method of operating a tufting machine of  claim 14  wherein 
     
     
         18 . The method of operating a tufting machine of  claim 14  wherein 
     
     
         19 . The method of operating a tufting machine of  claim 14  wherein 
     
     
         20 . The method of operating a tufting machine of  claim 14  wherein
