ABSTRACT:
Pin belt mechanism for movement of a continuous strip or web which has pin feed holes. The belt is annular and the pins are attached thereto along the length thereof, between the side edges thereof. The pins are easily and readily inserted into the belt and removed therefrom. The belt is rotatable and during at least a portion of each revolution engages a ramp which accurately directs each pin into a hole in the web for movement of the web. Each pin, in a substantially vertical position, moves in a straight line as it assists in movement of the strip. The pin then smoothly moves from the hole without further engagement with the web during that rotative cycle of the belt.
Each pin has one end portion which constitutes a web drive portion and which engages the web for movement thereof. The other end of each pin is a belt drive portion as the belt drive portion of the pin is movable into a recess in a drive wheel so that the pin and the belt move substantially linearly with rotative movement of the drive wheel. The belt drive portion of each pin also moves within a slot in an idler wheel to maintain proper lateral positioning of the belt with respect to the idler wheel.
