CAM GEAR
Cam gear is a mechanical device controlling winder speed in accordance with the position of the conveyance in the shaft, dial mounted profiled cams are used to depress follower rollers.
These are arranged to move the winder control input signalling devices such as selsyns, potentiometers, etc. Long range and man/materials drives are integral to the design.
