A pouch cell cutting apparatus according to an embodiment of the present disclosure, includes a top knife and a bottom knife for cutting a sealing part of a battery cell which includes a cell case and an electrode assembly housed in the cell case, wherein both side parts of the top knife comprises protrusion parts protruding toward the recessed parts formed on both side parts of the bottom knife, respectively, and wherein a corner part of the battery cell is cut by the protrusion part.

A punch assembly for creating clean holes in a wallboard sheet having at least one surface with a face paper layer. The punch assembly includes a frame having a lower assembly configured to support the wallboard sheet, a plate on an upper frame assembly being reciprocable relative to the at least one surface of the wallboard sheet, at least one stripper bushing connected to the plate, where the at least one stripper bushing including a hole and a piercing edge, and at least one punch configured to move through the hole in the at least one stripper bushing. In operation, the plate is moved against the at least one surface of the wallboard sheet so that the piercing edge of the at least one stripper bushing contacts the face paper layer and at least partially cuts the face paper layer prior to the at least one punch moving through the wallboard sheet to form at least one clean hole in the wallboard sheet.

The invention relates to an apparatus comprising a separating tool and comprising a counterpressure plate for producing contour geometries in adhesive-containing composite materials, wherein the separating tool can be moved in translational tool stroke directions between an inoperative position and a parting position normal to the counterpressure plate, and also to a method for producing contour geometries in adhesive-containing composite materials by means of an apparatus of this kind. The separating tool and the counterpressure plate can be actuated relative to one another by means of at least one actuator in at least one excitation direction with a ramp function and/or with a jump function. Each of these excitation directions lies in a parallel plane to a cutting edge plane of the separating tool. The present invention permits reliable separation of a stamped grid from laminate sections which remain on a carrier film.

Provided is a film processing device including: a first cutting blade and a first receiver base that are opposed to each other with a film including at least two layers interposed therebetween, and are configured to move toward and away from each other; and a first distance adjuster that adjusts, without being in contact with the film, a minimum distance between the first cutting blade and the first receiver base.

In some examples, a blank separating device includes at least one upper blank separating module and at least one lower blank separating module. The at least one upper blank separating module has a relief that includes at least three separating elements and/or contact elements, each including an operative surface and/or contact surface. The at least three operative surfaces and/or contact surfaces are able to each be arranged at at least three different distances in the vertical direction with respect to a carrier plate. Additionally, the at least one lower blank separating module has a relief that is matched to the relief of the at least one upper blank separating module.

In some examples, a blank separating device includes an upper blank separating module and a lower blank separating module. The lower blank separating module may include at least three supporting elements, each including at least one supporting surface for bracing blanks or scrap pieces. Further, the at least three supporting elements may be arranged so as to be positionable in at least three positions in the vertical direction, and two of the at least three supporting elements may be configured as supporting elements of a lower separating tool. Additionally, at least two supporting elements of the lower separating tool may each be arranged at least in three positions.

The invention relates to steel-rule cutting dies having a die block with at least one kerf configured to receive a corresponding steel-rule intended to be partially inserted into the kerf. The die block also has at least one element having magnetic properties, such as for instance a magnet, located or embedded in proximity to each kerf for providing a magnetic field that retains the steel-rule when the steel-rule is received into the corresponding kerf. The presence of the magnetic element(s) in proximity to the kerf(s) allows maintaining the corresponding rule(s) in position within its kerf even if the kerf is cut “loosely”. The corresponding rule may be quickly and easily inserted and accurately maintained even if the die block expand or retract under atmospheric variations. Among other advantages, the invention allows better stability of the cutting-die, faster leveling on press, and increased the number of re-knifing and longer run-time.
