摘要： PCT No. PCT/US82/00069 Sec. 371 Date Sep. 20, 1983 Sec. 102(e) Date Sep. 20, 1983 PCT Filed Jan. 20, 1982.A pair of specially designed suction wheels are preferably placed after the glue applicator on a known pinch bottomer bag-making machine. During manufacture, paper bags are guided horizontally through the machine by a conveyor forming part of the machine. With this arrangement, one of the suction wheels is placed under the bag, and the other wheel is placed over the bag in line. As each bag is moved by the conveyor, both suction wheels are brought into motion like a rolling operation. Each wheel has a shaft with a hollow channel going to a suction cup at the periphery of the wheel. The number of suction cups around the circumference of the wheel could be any amount. In a preferred embodiment, there are 12 equally spaced suction cups. A vacuum pump with a hose is connected onto the shaft. The pump draws air through the channel which comes from a suction cup so that, when the bag comes into the vicinity of the suction cup, the cup sticks on the bag layer. Because the bag is moving, the suction cup travels with the bag in the same direction. This action takes place simultaneously with both wheels. By doing so, the two layers of the bag cling to the suction cups. By making a radius, up and down, the bag opens.
