METHOD AND APPARATUS OF BUILDING MULTIPLE PACKAGES ON A SINGLE COLLET

摘要

An apparatus for forming multiple packages (19) on a single collet (22) includes a pair of collets (22a, 22b) that are mounted on a rotatable turret (64). A moving strand (14) is provided and the collet is rotated to wind the strand and build a first package on one end of the collet. The strand is reciprocated with a strand reciprocator (30) to lay the strand on the package surface (20) as the package rotates. After the first package is built, a strand positioner (70) and a secondary shoe (17) assist in transferring the strand to build a second package on the collet. After the second package is built, the turret is rotated while the cam (32) moves away from the collet and turret. The strand breaks off after a few revolutions of the second collet. Then, the cam moves toward the second collet to begin building a first package on the second collet.
