  • Bag removing apparatus
    Patent number: 3947021
    Abstract: An improved discharge apparatus for facilitating the removal and stacking of finished bags from a bag-making machine. An adjustable speed control means is operable to impart selective rotational velocity to a pair of opposed stacking wheels between which bags are travelling as they are discharged from the machine. Timing means operatively connected to the stacking wheels cause the speed control means to operate for a fraction only of the time interval of discharge of each bag.
