ABSTRACT:
A pair of continuously driven pull rolls of stock puller supported on a table having a longitudinal bed engage a web of the stock material to continuously unreel the stock material from a coil. The pull rolls are rotated by a drive shaft that is coupled to an input shaft of a feed roll unit. The input shaft is continuously rotated by a pulley-belt drive connection from a common power shaft. Continuous rotation of the input shaft is converted to intermittent rotation of a feed roll that intermittently advances the stock material to a stock material forming device, such as a material stamping or punching unit followed by a material cutting unit. The stamping and cutting units also include input shafts that are drivingly connected by pulleys and continuous belts to the common power shaft. The common power shaft is continuously rotated by a pulley-belt drive connection from an output shaft of a variable speed DC motor supported by the table. The output speed of the motor shaft is adjustable to rotate the common power shaft at a preselected speed to vary the feed rate of the stock material to the stamping unit. The stamping unit, as well as the stock puller and cutting units, being connected to the common power shaft are responsive to a change in the feed rate to maintain the operation of these units synchronized with the material feeding operation.
