A punching method includes: punching out a plurality of electrical steel sheets in a stacked state by a mold, wherein sheet thicknesses of the electrical steel sheets are set to be 0.35 mm or less, a Vickers hardness (test force 1 kg) of the sheets is set to be 150 to 400, and an average crystal grain size of the sheets is set to be 50 to 250 μm, a clearance of the mold is set to be 7% or more of a minimum sheet thickness of the sheet thicknesses of the electrical steel sheets and equal to or lower than 7% of a total sheet thickness of the electrical steel sheets, and a pressure that a sheet presser of the mold applies to the electrical steel sheets is set to be 0.10 MPa or more.

A packaging line station having a frame, a die assembly, a drive motor, and an anvil roller. The frame has a base with two vertical stanchions extending upwardly from sides thereof and a top cross-member affixed across the stanchions. The die assembly includes a yoke affixed to the cross-member, a die wheel rotatably affixed to side arms of the yoke, a drive shaft affixed to the die wheel and a cutting die affixed to the die wheel. The drive motor is connected to the drive shaft. The drive shaft and the anvil roller extend between the stanchions. The cutting die and the anvil roller and spaced apart by a nip for receiving a traveling web. As the web passes through the nip the web is cut by blades of the rotating die to form a slit. An adhesive resealable tape or label is then applied over the slit.

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.

A magnetic cutting and stamping pad (33), comprising a magnetic layer (331), and the magnetic layer (331) is connected to a pad layer (332) at a side facing a pattern medium (4); the magnetic field generated by the magnetic layer (331) penetrates the pad layer (332) and the pattern medium (4), attracts a cutting blade (5); during cutting and stamping, the cutting blade (5) completely penetrates the pattern medium (4) and enters above the pad layer (332), thereby ensuring that during the cutting and stamping the cutting blade (5) completely cuts out the pattern desired. The magnetic cutting and stamping pad (33) can position the relative locations of the cutting blade (5) and the pattern medium (4). The present invention also relates to a pattern cutting and stamping machine comprising the magnetic cutting and stamping pad (33), and a cutting and stamping method.
