Abstract
To permit pull-off of elastomeric yarn from a spool, without subjecting the yarn to tension, the spool (6) with the yarn (17) wound thereon is placed on a pair of horizontally extending support-and-drive rollers (3) which are driven at pull-off speed by a belt drive (7, 8, 10) from the textile machine via a right-angled drive (FIG. 3) from a drive pulley (11). The drive is reversible. The yarn is fed by frictional engagement of the yarn portion being pulled off the spool with a portion of the circumference of the driven support-and-drive rollers (3) and, if the weight of the spool is not sufficient to provide for suitable frictional engagement, the surfaces of the rollers can have knurling or a rubber coating thereon; they may be spring-loaded or weighted. Additional drive can be obtained by looping an endless belt (24) about the rollers, and seating the spool (6) in a concave depression formed by the belt as the spool is positioned between the support-and-drive rollers. The holder has a standard U-clamp to fit on the yarn supply holder ring of a circular knitting machine.
