  • Patent number: 4041847
    Abstract: The present apparatus is constructed for separating previously punched out workpieces from the surrounding waste material, for example, punched-out carton shapes. Preferably, the workpieces are arranged in a stack supported on a worktable. Power driven break-out tool means are located for up and down movement, as well as for lateral back and forth movement above the worktable. If desired, power driven push out means are arranged below the worktable with a push rail extending through a respective channel in the worktable. The break-out tool means and the push rail are arranged to be effective on a stack of workpieces on opposite sides and at opposite ends. The break-out tool and/or the push rail apply a levering action to the workpieces to break any lands or bridges which prior to such levering action connect the workpiece proper to the surrounding waste material.

  • Patent number: 4014234
    Abstract: This cutting apparatus includes a frame structure supporting a cutting roller and a counter pressure roller arranged at an angle relative to the feed advance direction of sheet material to be cut. Drive means are provided for the cutting roller and for the counter pressure roller in the form of a common drive chain positively interconnecting the rollers with a drive motor through an instantaneously operable clutch, such as an electro-magnetic or pneumatic clutch. A brake is provided between the cutting roller and the frame structure, whereby the control of the clutch and of the brake is such that engagement of the positive drive through the clutch disengages the brake and vice-versa.
