Abstract
An apparatus for automatically forming yarn reserve windings selectively on either end of an empty tube prior to winding a yarn package thereon utilizes a threaded spindle and spindle nut assembly for supporting one of a pair of tube clamping plates for selective longitudinal displacement of a tube clamped therebetween during rotation of the tube to place the yarn reserve windings thereon. The hand of the threaded connection between the spindle and spindle nut determines the longitudinal direction in which the tube is displaced and, in turn, determines the end of the tube about which reserve windings are to be formed. In one embodiment, the spindle and spindle nut assembly are exchangeable for a like assembly formed with opposite threads, thereby to alter the longitudinal direction of tube displacement. In another embodiment, an interiorly and exteriorly threaded bushing is interposed between the spindle and the spindle nut, to form oppositely mating threads between the bushing and the spindle and between the bushing and the nut. Set screws are provided to selectively fix the nut with respect to the bushing or, alternatively, to fix the spindle with respect to the bushing, thereby to change the longitudinal direction of tube displacement without necessitating an exchange of the spindle and nut assembly.
