Abstract: The equipment forms metal profiles on a stretch-bending machine on which a profile to be formed is held at its end by jaws connected to stretching rams and to a system for bending it against a convex punch member fixed to a toolholder table of the machine. The equipment includes a die member which is pressed against the punch member, once the profile has been bent against the punch member. An elastic material mandrel is placed inside the profile and the mandrel is compressed-expanded so that it presses the profile against internal surfaces of the punch member and of the die member when closed one against the other.

Abstract: An elastic matrix forming press comprising a frame including at least a bottom beam and a top beam united by link means, an actuator bearing against the bottom beam, and a forming assembly comprising an anvil resting on the piston of the actuator, a tool-carrier table, and a container including an elastic cushion engaged against the top beam, wherein said forming assembly: anvil, tool-carrier table, container, and elastic cushion, includes means enabling it to be exchanged for another having a tool-carrier table of different area, the section of said tool-carrier table corresponding to the inside section of the container.

Abstract: The installation, which includes a tubular enclosure, is provided with a plugging device at each end, each plugging device including a moving assembly that can be displaced perpendicularly to the axis .DELTA. of the enclosure. The moving assembly includes a plug of the stopper type provided with a seal, a spacer provided with a pull rod a drawer and a plugging body. The moving assembly is slidably mounted in a force take-up member. Via co-operation between sloping ramps carried by the plug and complementary sloping grooves in the drawer, the transverse displacement of the drawer causes the plug to be displaced axially.

Abstract: A method of manufacturing an assembly composed of two shaped and bonded parts in which the two parts to be shaped and bonded are placed on a header and die of a press, an adhesive is applied to at least one of the facing surfaces of the parts, the space between the header and the die is pressurized so that the parts are hot-formed to the shapes of the header and the die, and the header and die are then moved towards each other to press and bond the parts together.
