ABSTRACT:
In apparatus for transfering an elongated strip of material wound upon and attached to a first spool from the first spool to a second spool to which the other end of the strip is attached in response to driving torque applied to the second spool, means are provided for terminating the driving torque upon the second spool substantially immediately following passage of all of the elongated strip of material from the first spool to the second spool. In a preferred embodiment means are provided to cooperate with and rotate with the first spool during the transfer of the elongated material to the second spool. Upon complete passage of the strip of material to the second spool, the first spool ceases to rotate and means rotating with the first spool is configured to undergo and axial outward movement at this time as a result of its rotational inertia. This axial outward movement is utilized to trigger a signal causing termination of application of driving torque to the second reel.
