ABSTRACT:
Apparatus 500 for storing a variable quantity of strand material 200 comprises a generally cylindrical drum 110 that stores a layer of elongated strand material around its exterior surface. The layer is formed by wrapping the strand material in adjacent convolutions around the exterior surface which is energized to move in a direction which is parallel to the central axis 101 of the drum. Consequently, the strand material also moves in a direction that is parallel to the central axis. A winder assembly 510 is mounted on a first shaft 140 at an input end of the drum, and includes a strand payout member 511 for depositing strand material onto the drum. The drum is mounted on a second shaft 150 which contains the common support structure of the drum and the equipment for energizing the exterior surface. An unwinder assembly 520 is mounted on a third shaft 160 at the output end of the drum, and includes a strand-receiving member 521 for removing the strand material from the drum. The shafts are coaxial with each other and each is capable of independent rotational movement. Accordingly, the volume of strand material stored on the drum may be varied by changing the relative rotational speeds and directions of the different shafts. In this manner, the volume of strand material can be varied in order to buffer speed variations along a manufacturing line.
