ABSTRACT:
A drive system for a yarn false twisting apparatus is disclosed which may be readily converted to produce either S or Z twist, and which insures adequate tension of the drive belt. The apparatus comprises a pair of twist imparting members, and a drive belt system for rotating the twist imparting members which comprises a drive whorl positioned to engage a tangential belt, and a series of pulleys having a drive belt entrained thereabout for rotatably interconnecting the whorl and twist imparting members. The whorl and one of the pulleys are mounted coaxially on a whorl support member, which may be selectively positioned in one of two operating positions to place the whorl on opposite sides of the tangential belt. Another of the pulleys is an idler pulley, which is adjustably mounted for movement in a direction perpendicular to the yarn path of travel and so as to permit maintenance of an adequate tension on the drive belt.
