Abstract
A strapping machine for applying a band around an article comprises motor-driven rollers for advancing and retracting the band, and a band handling mechanism for fusing and cutting the band. The various band moving and handling operations are performed by cams mounted on a motor driven cam shaft. The rotation of the cam shaft is controlled by a sensor-actuating disk which rotates with the cam shaft. A photosensor is disposed at a fixed sensing position adjacent the disk. The disk includes circumferentially spaced light admitting slits which sequentially actuate the photosensor as the cam shaft rotates. The photosensor actuates a timer in an electronic control circuit for controlling rotation of the cam shaft.
