could have yarns driven by the same yarn feed roll 39 yarns from a yarn feed roll 39 quite proximal to the tufting machine 11 would occupy apertures 29 c and 29 d the apertures 29 are arranged in parallel diagonally offset rows the arrangement allows all the yarn ends for each of the yarn feed rolls 39 to be directed through the attachment 11 to the proper needles without introducing unwanted friction between individual yarns it will also be seen in fig4 that the servo motors 31 are advantageously set on base plates 30 of greater diameter than the yarn feed rolls 39 which permits the base plate 30 and attached motors 31 to be mounted on the support bar 26 with several motor mount bolts 38 additional fasterns 41 are used to secure covers 44 45 or circuit board assemblies over support 26 thereby defining wiring path 43 each feed roll 39 has a yarn feeding surface 28 formed of a sand paper like or other high friction material upon which the yarns are fed as shown in fig3 end caps 46 help ensure the yarns 22 remain on the feeding surface 28 and may protect motors 31 from dust or other contamination each of the yarn feed rolls 39 may be loaded with two yarns which is a light load providing little resistance compared to the hundred or more yarns that might be carried on a roll type yarn feed attachment the hundreds of individual yarns typically driven by a single scroll drive shaft or even the dozen yarns typically driven.
