ABSTRACT:
A conveyor cam adjusting apparatus permitting adjustment of the radial position of each cam on a drive shaft while it is rotating. A plurality of individual electric motors are mounted for rotation about a common drive shaft each motor being associated with a single cam. Each motor is provided with a means for manually selectively connecting it to a control means in order to enable an operator to rotate the associated cam relative to the common drive shaft while the shaft is rotating. A sensing means may be used to detect the position of each cam relative to a predetermined reference position and the output of the sensing means may be used by a computer control means to automatically selectively activate each motor to adjust the associated cam accordingly.
