Abstract: A mechanism for taking up the slack in a continuous web being fed to the take up mechanism by independent control means. The take up mechanism is automatically switched on whenever feeding of the continuous web by the independent control means commences. The take up mechanism continues to operate as the continuous web is being fed by the independent control means. At such time as the feeding of the continuous web is terminated the automatic take up mechanism continues to take up slack in the paper web until the tension in the paper web precludes further rotation of the geared spindle upon which the continuous web is being wound. Because of the pivotal nature of the drive assembly, comprising a motor and drive gear, the motor continues to turn the drive gear causing the latter to "walk" over the now stationary driven gear and in so doing causes the housing of the motor to come into contact with and depress a microswitch thereby interrupting the flow of electricity to the drive motor. The operative forces are such that the motor housing continues to maintain the microswitch in a depressed condition until feeding of the continuous web is resumed.
