ABSTRACT:
A dispenser is mounted on an X-Y coordinate arrangement of sleeves and guide shafts. It is driven by a motor mounted to a carriage assembly and having a magnetic follower unit driven by the motor and associated with a cam on a support made of ferromagnetic material, the cam being contoured as determined by the pattern of the gasket to be formed by the deposited gasket material. The magnetic follower unit is magnetically attached to the cam support and includes a wheel which is rotated by the motor and drives itself around the profile of the cam as the gasket material is deposited onto a work path of the workpiece. In one embodiment the cam is a chain and the drive wheel is a sprocket gear operating on the chain.
