Abstract: A die that may be rotated relative to a die holder to form an opening in different types of envelopes, cardboard boxes or other type of blanks or webs is provided. The window opening in an envelope blank is formed by using a sheet of material having a top surface and an outer periphery. A raised portion extends from the top surface of the sheet and includes a cutting edge adapted to cut the envelope blank to form the opening. A coupling means are included to selectively couple the die with the die holder in at least two orientations so that the position of said sheet may be changed relative to the die holder to alter the location in which said cutting portion forms the opening in the envelope blank.

Abstract: A rotary trimmer apparatus and signature trimming method are provided that enable operators to set a gap spacing between a rotating knife and an anvil at different predetermined sizes in an easy and accurate manner. The operator chooses the optimum knife/anvil spacing that produces a scissors-like cutting action on the particular type of signatures being trim cut and which does not cause premature knife dulling. The selected knife/anvil spacing is readily reproducable for future runs with the same operating conditions. This is true regardless of changes in the knife thickness as can be created by sharpening thereof, or knife replacement. For this purpose, a user operated control assembly including a control knob and calibrated indexer are provided. To keep the knife/anvil spacing at the set size during trim cutting operations, a temperature control system is employed that keeps axial expansion of the knife spindle shaft from reducing the gap size.

Abstract: The application relates to a device for quickly and precisely aligning and fixing foil blades on the body part of a blade roll. The rotary blade roll has a rotating shaft, at least one roll body part arranged with torsional strength on the rotating shaft, at least one foil blade supported by the roll body part, and a row of holding and positioning pins in the roll body part. Magnetic elements arranged in rows retain the foil blade flatly on the peripheral surface of the roll body part. The foil blade has a thin flexible magnetically permeable base plate and at least one sharp one-piece cutting edge of a predetermined cutting shape projecting from the base plate. The base plate has a leading edge, a trailing edge, two side edges opposing each other, and, in a front zone adjoining the leading edge, a plurality of slots aligned with the cutting edge.

Abstract: A bank cutter positioning device installed in a cutter seat at a side having a dovetail groove comprises a locking block, an elastic element, a roller and a handle. The locking block having an end pivotally installed above the dovetail groove. The elastic element installed between a resisting surface of the seat and a locking block. The roller pivotally at another end of the locking block. Therefore, by moving the handle, the roller of the locking block will move circularly on the sliding surface and curved surface at the lower side of the handle so as to control the releasing and locking operation of the locking block. The roller causes the driving distance between the locking block and the handle to reduce to suit a dovetail seat with a contact surface having a small tilt angle, and has the effects of rapid positioning and detaching.

Abstract: A device for cutting wood or other materials comprises a saw blade clamping device for radially and/or axially fixing circular saw blades mounted axially displaceable on a drive shaft. Support bodies are provided axially displaceable on the drive shaft for each circular saw blade. The axial displacement of the circular saw blades takes place by guide spindles running parallel to the axis of the drive shaft and passing through the support bodies. At least one clamping element is mounted in the drive shaft 1, 20. The clamping element is mounted radially displaceable. In a first stage, the circular saw blades which are mounted on the support bodies are thereby displaced. In a second stage, the circular saw blades or support bodies are connected to the drive shaft in keyed and/or force locking engagement. Through the device, a displacement of the cutting width is possible without the time and labor intensive dismantling of the saw blades.

Abstract: Method and a device for slitting a material web traveling in the run direction in which at least one knife unit with a cutting edge, and arranged on a carrier that is movable transversely to the run direction in a machine frame, is positioned. A measurement device measures the position. The position measurement is improved in that the measurement device has two measurement transducers. A first measurement transducer is arranged on the carrier and measures the distance from the cutting edge to a reference point that is fixed with respect to the carrier. A second measurement transducer measures the distance between a reference point that is fixed with respect to the carrier and a zero point that is fixed in the machine frame. The absolute position of the cutting edge is established by combining the two distances.

Abstract: Upper and lower rotating drums (13, 14) having shearing blades (13a, 14a) are supported by a bearing frame (12) via eccentric sleeves (15, 16). Only the upper rotating drum (13) is rotated by a drive motor 17, while the eccentric sleeves (15, 16) are rotated by a drive motor 25, so that the rotating drums (13, 14) can be made to approach and separate from each other. Interlocking gears (29, 30) are fixed to shaft end portions of the rotating drums (13, 14) to permit interlocking of the rotating drums (13, 14) when these drums approach. Oldham's couplings (41, 42) are interposed between the interlocking gears (29, 30) and timing gears (33, 34) to rotate the rotating drums (13, 14) constantly and synchronously.

Abstract: A machine tool has a work table which defines a working surface and has a cutting tool which is attached to and movable with respect to the work table. The position of the cutting tool with respect to the working surface is controlled by a mechanism which elevates the cutting tool with respect to the working surface and angulates the cutting tool with respect to the working surface. The cutting tool is mounted to a support plate which is pivotably attached to the work table. The elevating mechanism includes a threaded rod and a nut which engages a pivoting link. The pivoting link also engages the cutting tool. Rotation of the threaded rod pivots the link which in turn raises and lowers the cutting tool. A spring biases the cutting tool towards its lower position to remove play between the components. The angulating mechanism includes a lever, two cams and a locking rod. Rotation of the lever moves the locking rod longitudinally due to the action between the two cams.

Abstract: The invention is an apparatus for cutting metal sheet having two rotatable drums, wherein the metal sheet passes between the drums for cutting. Each of the drums has a cutting blade moved into and out of cutting position by an axial actuator rod. The cutting blade includes two sets of rollers bearing against one of a pair of profiled side surfaces of the axial actuator rod.
