Abstract: An apparatus for slitting a running paperboard web includes a thin high speed rotary slitting blade that is plunged through the moving web and into a slot between a pair of anvil surfaces supporting the web on the opposite side. Because the slitting blade and the anvil surfaces are vertically separated and pre-positioned before order change, an adjustment apparatus is provided to spread the anvil surfaces apart to provide an open gap with a large target for blade edge when it is plunged through the web and into the slot. The anvil surfaces are then closed to bring the edges of the surfaces against the opposite faces of the blade for running operation. Preferably, the anvil surfaces are mounted on brackets hinged together below the surfaces to move the edges of the surfaces defining the slot between the opened and closed positions in the manner of a clam shell.

Abstract: A cutting table for cutting pieces of fabric. The table has a fabric supporting surface mounted on a frame. A cutter is manually movable along a linear cutting path that is substantially perpendicular to an edge guide.

A manually powered drive supports the first and second light emitting devices in a spaced apart relationship, and the drive is manually operable to move the light emitting devices through equal displacements in opposite directions substantially perpendicular to the linear cutting path. The light emitting devices are used to quickly align the fabric, so that it can be cut to a desired width.

Abstract: A cutoff saw assembly incorporates a robot assembly with a compliant cutting apparatus to remove various undesired metal extensions from a casting. The assembly cooperatively and conjunctively controls the position of the casting using the robot assembly and the force exerted by the cutting apparatus on the casting using a compliance control system.

When replacement of the upper knife is required, the user releases the air pressure and a spring engaging the plunger member forces the same outwardly to allow for removal of the clamp member thereby providing unobstructed access to the upper knife.

Abstract: An apparatus is provided for processing mail by severing an edge of each envelope in a stack of mail. The apparatus includes an input bin for receiving a stack of mail. An agitator confronting the stack of envelopes in the input bin reciprocally displaces the bottom envelope in the stack of mail to provide separation between the bottom envelope and the remaining envelopes in the stack. A feeder feeds the bottom envelope from the input bin to a transport that conveys the envelope along an envelope path. A cutter positioned along the envelope path severs one edge of the envelopes. The transport discharges the opened envelopes onto a return conveyor that conveys the opened envelopes to a stacking area where the opened envelopes are stacked.

Abstract: An object of the invention is to provide a blade for cutting a copper foil being capable of further decreasing the amount of slivers generated at the time of processing, e.g., cutting, punching, and perforating a copper foil and also capable of making the size of the slivers smaller. To achieve the purpose, a disk-like blade to be employed for a copper foil-slitting apparatus is coated with diamond-like carbon (DLC) or diamond-like carbon soft (DLC-soft) on at least a part to be brought into contact with a copper foil at the time of cutting. The coating reduces the unevenness of a blade surface, thereby providing a face being scarcely scratched with the copper foil. Subsequently, the amount of the slivers generated is remarkably decreased and the cutting property is improved.
