A tool for thermoforming a container having a base and an upstanding sidewall walls or walls. The tool includes a mould having a profile shaped to form the exterior shape of the container and a plug adapted to be inserted in the mould to define the interior of the container. The plug has a lower face adapted to define the profile of the base of the container. The profile of the lower face of the plug has at least one groove therein defining, in use, a rib upstanding in the interior of the base of the container.

The disclosure relates to a film transportation plate and a film transportation system for transporting a film web through processing stations of a film packaging machine. The film transportation plate has two opposite lateral edges and, therebetween, at least one mold impression for thermoforming the film web. Retainers for the film web are arranged on the two lateral edges. The retainers are each formed by a fixed clamping surface and at least one clamping jaw, which is movable relative to the clamping surface, for pressing the film web so as to clamp it against the clamping surface. The retainers also each have at least one retaining magnet for attracting the clamping jaw against the clamping surface, and an actuating extension for lifting the clamping jaw off the clamping surface. The film transportation system also includes actuating means which act on the actuating extensions of the clamping jaws.

The present invention provides a manufacturing device of a battery case including a first mold including a first space part having a shape corresponding to a storage part formed therein; a second mold including a second space part having a shape corresponding to the storage part and a through-hole communicating with the second space part formed therein, and coupled to the first mold with a laminate sheet interposed therebetween; and an air pressure regulator mounted in the through-hole in a state in which the first space part and the second space part are isolated from the outside, and increasing or decreasing an air pressure of the second space part through the through-hole to stretch and modify the laminate sheet into a shape corresponding to the first space part or the second space part.

A multi-sheet component for a utility vehicle that includes at least one gap between at least two of the sheets, thereby providing a component that enhances worker safety by increasing component stiffness and reducing component thickness. The component is manufactured through multi-sheet thermoforming and uses a conical frustum corrugation to increase stiffness.

The present invention relates to a method for providing a product viewing window in a container. The container has at least a body ply and a liner ply, wherein the body ply has at least one aperture therethrough. The liner ply is adhered across the aperture, forming a window into the container. A window-finishing machine that comprises at least two platens and, optionally, a machine pocket positioned between them, a heating element extending through at least one of the platens, and a pressurized air device engages a container. The heating element heats the window of the container to the desired temperature, pressurized air is injected into the container such that the window is forced at least partially through the aperture of the container (and optionally into contact with the machine pocket wall), and the container window is then cooled to the desired temperature.

Provided are a sheet material in which a skin material can be adhered to a base material. A sheet material 2 for forming a design surface of a product by being adhered to base materials 68a, 68b includes a sheet-like skin material 20, and a sheet-like stretchable material 25 laminated on a rear surface side of the skin material 20 and having higher stretchability than the skin material 20. The stretchable material 25 has a rectangular shape in plan view, and include grippable areas 27a, 27b, 27c, 27d on which the skin material 20 is not laminated and which are respectively provided in portions including four edge sides 26a, 26b, 26c, 26d facing each other in plan view. In the skin material 20, five linear cut portions 24a, 24b, 24c, 24d, 24e are formed in a non-design area 23 other than the design areas 22a, 22b.
