An arrangement for adjustably enabling the holding of a tool in a tool holder plate for punch press machine. The tool holding arrangement comprises a tool holder plate having a size adjustable tool gripper opening therein. An adjustment bolt bore is arranged adjacent the size adjustable tool gripper opening wherein the adjustment bolt bore has an upper end of conical shape and a lower end opening of pyramidal shape with trapezoidally shaped walls. An expandable adjustment gap is arranged between the size adjustable tool gripper opening and the adjustment bolt bore. A pair of flexure slots are arranged in the tool holder plate, to define a pair of flexible gripper claws therebetween. Changes in the adjustment gap by adjustment of the bolt in the bolt bore enhances the evenly opened size of the tool gripper opening to permit the tool to be properly installed therein.

The invention is directed to a cutting post for mounting on a cutting apparatus and to the cutting apparatus. The cutting apparatus has at least one cutting blade and at least one cutting post. The cutting post includes at least one receptacle for the cutting blade and at least one cutting element having a cutting edge arranged at the head end of the cutting post. The cutting blade has a cutting blade edge and is held in the receptacle of the cutting post. The cutting blade edge of the cutting blade and the cutting edge of the cutting element of the cutting post conjointly form a continuous cutting contour.

A device by which thin-walled materials, such as labels and flat lids for containers, can be punched in micro or small quantities. The device includes a band steel cutting edge (11) that is elastically mounted in the punching direction. The matrix is likewise elastically held on the matrix plate perpendicular to the punching direction by virtue of a matrix seat (33) fastened to the region in the matrix plate (27) that is adjacent to the opening (29). On the matrix seat, an elastically deformable intermediate plate (47) is placed, and the matrix (55) is placed on the intermediate plate.

A hole cutting apparatus for cutting a hole in a tubular structure, which includes a center shaft, a slide mount rotatably attached to the center shaft, a slide rail slidably attached to the slide mount; a cutter attachable to the slide rail so as to move with the slide rail, and a cutter height roller attached to the cutter. The cutter height roller is structured and arranged to maintain the cutter at a distance from a cutting surface of the tubular structure as the hole is cut.

A method of making a counter-die cutter for a die cutting machine having a die cutter and respective counter-die cutter includes: acquiring a digital drawing of a die cutter to be made, which is provided with comparing means; acquiring a digital drawing of a respective counter-die cutter to be made; providing a wooden support of the die cutter; making a plurality of comparing means on the support of the die cutter; making the die cutter; detecting the position and/or orientation of the comparing means of the finished die cutter; comparing the detected position and/or orientation with corresponding position and/or orientation of the comparing means being in the digital drawing of the die cutter; modifying the digital drawing of the counter-die cutter based on the detected differences to adapt the digital drawing to the finished die cutter; and making the counter-die cutter based on the modified digital drawing.

The invention relates to a multi-pack container which defines a series of containers (11) formed in a plastic sheet (L) that comprises at least a layer of PET (polyethylene terephthalate), and in which said containers (11) are joined by bridges (12), provided with a pre-cut upper line (13) and a pre-cut lower line (14) for breaking the bridge (12). The pre-cut upper line (13) and a pre-cut lower line (14) are arranged parallel to one another, laterally separated in a horizontal direction and vertically separated to prevent heating by compression and a variation of the properties of the PET layer, allowing for clean breakage of the bridge by rotating the containers with respect to said pre-cut upper and lower lines. The invention also comprises a machine for manufacturing the multi-pack container.

A clamping mechanism is provided to clamp a die set on a carrier of a machine. The clamping mechanism utilizes a first pushing block to push a locating shaft of the die set to allow a top surface of the locating shaft to contact a mounting surface of the carrier and utilizes a second pushing block to push the locating shaft to allow a first contacting surface of the locating shaft to contact a reference surface of a cage base such that the die set will not clamp on the carrier of the machine with shift or skew errors.

The present invention relates to a thermoform packaging machine, comprising a controller and a film punch, which includes a lever mechanism, a tool, upper part and a tool lower part. At least one of the tool upper part and the tool lower part are movable by means of the lever mechanism such that the tool upper part and the tool lower part approach each other.

A precision positioning device of a unit-type die cutting & hot stamping machine includes a positioning element on an input end of a first imprinting element and a positioning element on an output end of each imprinting element. Two neighboring positioning elements accomplish the positioning between the two positioning elements together. Each positioning element is constituted by a positioning assembly installed symmetrically on each end of the imprinting element. The positioning assembly includes a positioning rod which can rotate against an installation shaft. Each positioning rod includes a positioning block which is provided with a reference surface. A rear side of the gripper is provided with a reference matching surface. By the positioning elements, the accuracy in the art of die cutting & hot stamping can be assured when the machine is performing a multiple-working-position procedure.

A rotary die cutting system comprising: a rotary die cutter (21) having a die cutting cylinder (22) that can rotate about a die cutting axis; a counter-pressure cylinder (23) that can rotate about a counter-pressure cylinder axis; and an adjusting mechanism, by means of which a gap width between the die cutting cylinder and the counter-pressure cylinder (22, 23) can be adjusted; and a die cutting sheet (25) that can be fixed to the die cutting cylinder (22). A machine-readable information carrier (26) is associated with the die cutting sheet (25), more particularly the die cutting sheet (25) has said information carrier, by means of which carrier at least the die cutting sheet (25) can be identified, and the rotary die cutting system has a detection unit (27) designed to read out the information carrier (26). The adjusting mechanism has a servomotor and a control unit (28) and is designed to adjust the gap width according to the die cutting sheet (25). Also disclosed is a method for adjusting the gap width.
