  • Patent number: 9145267
    Abstract: A transfer device equipped with a rotating body having multiple workpiece holding units that support a holding surface holding a continuous sheet member through suction that faces outward in the radial direction of the rotation body. Between adjacent workpiece holding units, arranged in the direction of rotation, the device is equipped with bed knives that produce single sheets by sandwiching and cutting the continuous sheet member in combination with a cutter member arranged to face the outer surface of the rotation body. The workpiece holding units pivot to follow the radial direction of rotation of the rotation body and modify the long direction face of the single sheets when the rotation of the rotation body takes the workpiece holding units past the position where the cutter member is arranged. At this time, the workpiece holding units are arranged so that part of the workpiece holding units passes over a bed knife.
