A device for processing workpiece sheets for packaging, includes a processing station through which the workpiece sheets are transported in succession, at least one changeable tool (2, 10, 18) that is specific to the processing and is moved against the sheet introduced in the processing station to process the sheet, at least one holder (11) on the device side for the changeable tool (2, 10, 18), the holder being adjustable for aligning the changeable tool (2, 10, 18), a central electronic control unit (37) for controlling the device, the control unit (37) having a memory for storing specific setting position data for each individual specific changeable tool (2, 10, 18), electronic digital sensors (36) for determining the current position of the holder (11), which sensors are coupled to the control unit (37), and digital display devices (38) that are coupled to the control unit (37) and display the target position and the actual position of the holder (11) or of parts coupled thereto, or display the relation of the target position and the actual position for the individual specific changeable tool (2, 10, 18).

A formed sheet metal material (100) and methods, tools (1, 2, 8) and apparatus for forming the sheet metal material (100) in which a pattern of projections and depressions are cold worked in a first portion (101) and, simultaneously, indicia (103) is embossed in a second portion (102) of the sheet material (100). The cold worked portion (101) is formed with the projections and depression configured and distributed such that lines drawn on a surface of the formed sheet material (100) between adjacent rows of projections and depressions are not rectilinear. The indicia (103) is indicative of the alignment between the tools (1, 2, 8).

A graphic arts support assembly is operable to be used with a graphic arts plate assembly in a press. The graphic arts support assembly and the plate assembly are configured for removable association with a lift mechanism including a shiftable lift element. The support assembly includes a graphic arts magnetic support structure operable to removably support the graphic arts plate assembly. The magnetic support structure includes a support plate, a magnet fixed relative to the plate, and an alignment element projecting from the support plate. The support assembly is operable to be mounted on the lift mechanism so that the lift element is aligned with a lift opening of the support plate, with the lift element shiftable through the lift opening to locate at least part of the graphic arts plate assembly away from the support plate.

The disclosure relates to a press plate for creating deep structures in panel-like products, for example in wood-based boards or laminates made of resin-coated papers, composed of a metallic base body, in which strip-shaped and/or frame-like webs, which have a higher thermal conductivity than the base body, are inserted in depressions provided.

A tool unit 20 and a press 21, particularly an embossing press. The tool unit 20 is simply and quickly arranged in or removed from a holder 23 of the press 21 in order to carry out a quick tool change with short downtime of press 21. For this purpose the tool unit 20 comprises a first tool 45 and a second tool 46 that are arranged along a tool axis A on a tool carrier 31. By means of a tool guide device 47, the second tool 46 is movably supported in a guided manner relative to the tool carrier 31 and the first tool 45, independent from guide devices of press 21. Therefore, the tool unit 20 can be prepared and set up during the ongoing operation of press 21. If desired or necessary, the prepared tool unit 20 is exchanged against the presently used tool unit 20.

A method of marking indicia on tab stock used to provide tabs for use with can ends. The method comprises providing the tab stock to a tab press comprising a punch and a die. The punch comprises a set of raised features and the die comprises a respective set of recessed features such that the features cooperate to deboss said indicia on regions of the tab stock within tab forming areas that face outwardly when the tabs are attached to a tab end. The features are such that, when the press is fully closed, the spacing between at least part of each of the raised features and at least part of each of the respective recessed features is less than the thickness of the tab stock in said regions within tab forming areas.

A graphic arts support assembly is operable to be used with a graphic arts plate assembly in a press. The graphic arts support assembly and the plate assembly are configured for removable association with a lift mechanism including a shiftable lift element. The support assembly includes a graphic arts magnetic support structure operable to removably support the graphic arts plate assembly. The magnetic support structure includes a support plate, a magnet fixed relative to the plate, and an alignment element projecting from the support plate. The support assembly is operable to be mounted on the lift mechanism so that the lift element is aligned with a lift opening of the support plate, with the lift element shiftable through the lift opening to locate at least part of the graphic arts plate assembly away from the support plate.

A method for manufacturing a product having a surface provided with embossments, includes bringing a material web is in contact with a roller. The roller is provided with a relief at its surface, with which, via this relief, embossments are formed in the material web. The roller has a circumference of which, or at least certain parts thereof that are variable, or alternatively the circumference of the roller is variable by making use of embossing elements, wherein the mutual angular position thereof is adjustable.
