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.
Claims10
Hooper apparatus for connecting steel bands having a band tensioning mechanism comprising tension roller means for engaging said bands, motor means including a first motor for driving said tension roller means with low speed at high torque and a second motor for driving said tension roller means with high speed at low torque, said tension roller means being prestressed toward a base support, and plural stage reduction gear means connecting said tension roller means with said motor means, said second motor being connected to any but the first stage of said plural stage reduction gear means, with said first motor being connected via a first stage to said plural stage reduction gear means and with one of said first and second motors being connected by means of a compensating clutch to said plural stage reduction gear means.
