20220024169 · 2022-01-27 ·

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.

TAB PRESS AND METHOD OF MARKING INDICIA ON TAB STOCK
20210362537 · 2021-11-25 ·

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.
