The invention relates to a stripping claw for insertion into a stripping tool, which is intended to strip a break-off part from a planar workpiece and comprises at least two tips (6.1, 6.2) to be placed onto the break-off part. According to the invention, the region between the two tips (6.1, 6.2) has a concave design.

The invention relates to a device for inserting a first ram (1) or a second ram (2) in an alternating manner into a ram feeder (3) of a device for inserting stripping pins and stripping claws into a stripping tool, wherein the first ram (1) and the second ram (2) are mounted on a retaining plate (6) so as to be moveable in a first movement direction (4), wherein the ram feeder (3) can be moved in a second movement direction (5), and wherein the first movement direction (4) is orthogonal to the second movement direction (5).

The invention relates to a guide sleeve for a machine tool for the automated placement of stripping claws, wherein a receiving slot (2) is provided at one end and a solid material base (4) is provided at the other end, and wherein a machine-tool stop (3) is positioned between the receiving slot (2) and the solid material base (4). The guide sleeve is characterised in that the receiving slot (2) is an elongate hole.

A blank separating device includes at least one upper blank separating module, the at least one upper blank separating module having a first relief, the first relief comprising 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 individually arrangeable to at least three different distances in a vertical direction with respect to a carrier plate within which the at least three separating elements and/or contact elements are mounted. The blank separating device further includes at least one lower blank separating module that has a second relief comprising a plurality of supporting elements. The second relief matches, at least in complimentary vertical positioning, the first relief of the at least one upper blank separating module.

A blank separating device includes an upper blank separating module and a lower blank separating module. The lower blank separating module includes at least three supporting elements. Each supporting element includes at least one supporting surface for bracing blanks or scrap pieces. Two of the at least three supporting elements are configured as supporting elements of a lower separating tool. The two supporting elements configured as supporting elements of the lower separating tool are each arrangeable in at least three positions in a vertical direction.

An arrangement for transforming a planar support (2) includes first and second rotating cylindrical transformation tools (16, 17), cooperating to convert the support (2), first and second side bearings (26, 27), holding the first tool (16) for rotation (Rs), third and fourth side bearings (29, 31), holding the second tool (17) for rotation (Ri), spacers (43, 44, 46, 47) having an inclined face (48) and slidable (S) to adjust the respective distances (e, e1, e2) between the first and third bearings (26, 29) and between the second and fourth bearings (27, 31), to set a radial gap (20) between the two tools (16, 17). In another solution, either as an alternative to or in cooperation with the first solution, the spacer (43) is moved (S) by a differential screw (57) having a first thread (58) that engages with a tapped hole (59) in an integral part (61) of one of the bearings (29) and a second thread (62) different than the first thread (58) and engaging with a tapped hole (63) in the spacer (43).

In a device for breaking out a workpiece (3) from a material sheet (2) through an opening (4) of a die (1) by means of a breakout tool (5), the die (1) is to have a plug-in unit (22), wherein a breakout module (9.1-9.4) is insertable into the plug-in unit (22), wherein the breakout module (9.1-9.4) is composed of an insert (10) and of a module lobe (11), wherein the insert (10) has a surface (16) and a shearing edge (17), wherein the shearing edge (17) toward a bearing face (12) of the module lobe (11) configures an offcut length (18), and wherein the offcut length has a height (h) of 0.8 mm to 1.8 mm, and preferably of 1.5 mm.

The invention provides a method of cutting out an opening in a flat cardboard blank (10, 12) that is for use in manufacturing a package, wherein a first portion (18) of the blank (10, 12) and an ejector tape (34) that face each other are pressed together between a presser tool (24) and an activation tool (26) that face each other so as to cause the ejector tape (34) to stick exclusively on the first portion (18) of the blank (10, 12). The invention also provides an ejector tape for such a method.

A nick breaking device includes: a conveyor forming a transfer path on which a plate-shaped element having nicks formed thereon is transferred; and one or more pressing rollers provided on the transfer path of the nicks of the plate-shaped element so as to press the plate-shaped element such that the plate-shaped element is transferred while having a continuous wave shape and to break the nicks formed on the plate-shaped element.

A rotary cutting die including a curved die board having a series of product ejector openings formed completely through the die board. Secured to an inner surface of the die board is a substrate. A series of product ejectors are secured to the substrate and project therefrom through the product ejector openings and past an outer surface of the die board. These product ejectors function to engage a portion of a die cut product passing through the nip and exert a force on the die cut product which assists in separating the die cut product from the rotary cutting die.
