  • Patent number: 8997616
    Abstract: It is intended in an apparatus for successively making plastic bags that a plastic film 1 is cut by a Thomson blade 3 without making the Thomson blade 3 pressed with a large force. The Thomson blade 3 is brought into contact with the plastic film 1 on one of opposite sides of the plastic film 1 in a direction of thickness thereof while a rolling member 4 is brought into contact with the plastic film 1 and rolled and moved along the plastic film 1 and the Thomson blade 3 on the other side of the plastic film 1 in the direction of thickness thereof. The plastic film 1 is therefore sandwiched between and cut by the Thomson blade 3 and the rolling member 4 to successively make plastic bags.

The material is fed along parallel feed paths by first and second material feeders which move the material toward respective cutters. The operation of the feeders and the cutters is controlled by a programmable controller which permits each of the material strips to be fed and cut to form pieces of predetermined length which may be removed by an operator or conveyed to a subsequent station for further processing. In a further embodiment of the invention, the feeders are movable relative to a work station comprising a cutter associated with a common feed path extending between the cutter and a sewing apparatus. As each of the feeders is aligned with the work station, a predetermined length of material may be cut off by the cutter and conveyed along the common feed path to the sewing station.

    Abstract: An apparatus for perforating a sheet material provides for a perforating die located intermediate two orbital rollers. The two orbital rollers move in orbital paths in the same orbital direction at the same speed and in positions which are 180 degrees apart. Each roller acts as a temporary storage input and output in opposite phase from each other so that incoming sheet material is alternately stored and dispensed as a loop on the orbital roller. Since the rollers are out of phase, this permits a segment of the sheet material to be stopped intermediate the orbital rollers so that the perforating die can act on the stopped segment.

  • Patent number: 4848631
    Abstract: A cam shaft of a press feed having a first pair of cam surfaces is rotated at a preselected speed depending upon the speed of the press. Continuous rotation of the cam surfaces is converted to intermittent oscillating rotational movement of an output shaft through a preselected angle of rotation by a pair of cam followers. The cam followers are nonrotatably connected to an output shaft that is connected by an adjustable linkage mechanism to a slide block. The intermittent oscillating rotational movement of the output shaft is transmitted to the slide block to advance the slide block containing stock material such as a bar or wire through a preselected distance corresponding to a preselected feed length. The feed length is adjustable by changing the length of travel of the linkage mechanism with respect to the degree of rotation of the output shaft.

    Abstract: A trim press for severing cup-shaped articles from a sheet of thermoplastic material in which the articles have been integrally formed as by a vacuum forming operation. A horizontally reciprocable punch is driven to sever articles positioned in a stationary die by a linkage arranged to drive the punch at a relatively slow speed during the severing operation to achieve a smooth shearing separation of the relatively soft thermoplastic material. The sheet is fed into the die in step-by-step movement through vertical sheet guides fixedly mounted in a treadle which is reciprocated with the punch at a proportionate speed. A flexible sheet guide connected between the guides in the treadle and a fixed point on the machine frame flexes to accommodate reciprocation of the treadle while continuously guiding the sheet to the guides on the treadle. Feed fingers mounted on the treadle advance the sheet to the die in step-by-step movement synchronized with the stroke of the punch.
