Abstract
Hooper apparatus for joining together a pair of bands including a first motor connected with an output shaft through a plural-stage reduction gear system wherein one gear stage of the system is connected with a second motor which enables a faster driving speed of the apparatus with a lower driving force. A compensating clutch is provided on the driving side of the one gear stage, preferably an overrunning clutch, with the clutch being arranged to be used when the driving speed of the second motor has decreased to an extent that it is overtaken by the driving speed conditional on the first motor which carries a tension roller engaging the bands to be joined. The first motor then operates to drive the output shaft with a lower circumferential speed and with a higher driving force.
