A system for punching at least one hole in at least one sheet-like material. In particular, a device and system that is uniquely configured and sized to be a table top unit for automatic punching of paper. The system has a sheet feeder, a sheet transport module and a punching die module that allows a punching die to be easily changed. The paper being punched by the punching die module is moved only a short distance from the sheet feeder and while the paper is still supported by the sheet feeder. The sheet feeder is located outside the system's housing to facilitate adjustment and troubleshooting. This advantageously allows for a smaller, compact unit that is effective and efficient.

A punching and binding machine used to bind sheets to discs. The machine may include a lever with a first arm, a second arm, and a third arm. Each arm may be pivotally and slidably connected to minimize the force required by a user to punch cutouts in a stack of sheets. The lever may include a flipper connected to a binding member to actuate punching and binding simultaneously.

A bundle breaker including first and second platen assemblies mounted above upstream and downstream breaking supports with first and second actuators for moving the platen assemblies toward and away from the breaking supports and a third actuator for moving the downstream breaking support to perform a breaking operation. The first platen assembly and/or the second platen assembly each includes an upper platen assembly and a lower platen assembly supported by the upper platen assembly, the upper platen assembly including an upper platen and a support for the upper platen and the lower platen assembly including a lower platen supported for movement relative to the upper platen in the vertical direction and relative to the upper platen in the longitudinal direction.

Disclosed is a cutting control method that is performed by a cutting device including a cutter that cuts a cutting target medium with a cutter blade based on predetermined design information. The cutting control method includes, in response to the design information including unnecessary region information indicating an unnecessary region to be removed after a first cutting in which the cutter blade cuts the cutting target medium based on the predetermined design information, controlling the cutter to perform special cutting inside the unnecessary region. The special cutting is performed with a second cutting method different from a first cutting method in which the cutter blade is moved to perform the first cutting.

A bundle breaker has downstream and upstream breaking supports, first and second platens located over the respective breaking supports and first and second actuators to move the platens to selectively clamp portions of a log against the breaking supports. A third actuator shifts the downstream breaking support relative to the upstream breaking support from a first position to a second position to break a bundle from the log. A scrap chute is mounted below a junction of the upstream and downstream breaking support to catch scrap material falling between the upstream support and the downstream breaking support. Each time the downstream breaking conveyor is shifted to the second position, scrap in the chute is jolted and is shifted toward a discharge opening of the scrap chute and, optionally, into a scrap drawer.

An auxiliary platen assembly configured to be mounted to a primary platen assembly of a bundle breaker includes an auxiliary platen having an upper surface configured to be frictionally engaged by a contact surface of a primary platen and having a lower surface configured to press against a top of a bundle when the auxiliary platen assembly is mounted to the primary platen assembly. First and second walls overlie first and second upper edge regions of the auxiliary platen. At least one first connector connects the first wall to the first edge region of the auxiliary platen in a manner that allows movement of the auxiliary platen toward and away from the first wall, and at least one second connector connects the second wall to the second edge region of the auxiliary platen in a manner that allows movement of the auxiliary platen toward and away from the second wall.
