Abstract
A container top is made from a metal and plastics laminate. The blank from which the top is formed is severed from the main laminate sheet by forming a channel section indentation around the blank outwardly of a line defining an engagement and sealing contact portion of the container top. - The indentation extends through the full thickness of the plastics layer and part-way through the metal layer. A punch is then used to sever the laminate along the line of indentation of the metal layer. EPAB- EP--86800 B The method of severing a laminate (10) of the type including a layer (11) of a metal and a layer (12) of a flexible synthetic plastics material, the method comprising forming a channel-shaped groove (13) in the laminate (10) along a line (14) on which the laminate is to be severed, the groove (13) extending through the plastics layer (12), and severing the laminate (10) along the line (14) of the groove, characterised in that the groove (13) is of such depth as to extend through the full thickness of the plastics layer (12) and through a part of the thickness of the metal layer (11), and is formed by indentation of the laminate along the line (14), such indentation causing lateral displacement of the plastics material on either side of said line (14). (9pp) USAB- US4599126 A The method is for severing laminates of the type having a metal layer and a synthetic plastics layer. The method comprises forming a channel section indentation i in the laminate along a line on which the laminate is to be severed. - The identation is of such a depth as to extend through the full thickness of the plastics layer and through a part of the thickness of the metal layer. The plastics material along the line of the indentation is substantially displaced laterally, and the laminate is severed along the line of the indentation in the metal layer.
