The invention is directed to a forming device, especially internal high-pressure forming device, with a multiple-part forming tool and a clamping device which holds the parts of the forming tool together against the deforming action. In the novel forming device, according to the invention, the clamping device and/or the forming tool have/has at least one counter-clamping device which compensates at least partially for deformations of the mold cavity during forming. The possibility of compensatio...

A forming fabric has a paperside warp layer and a machine side warp layer. The fabric comprises at least one set of machine side wefts and at least one set of weft triplets, the weft triplets together forming two continuous weft paths on the paperside. All of the weft triplets interweave with at least some paperside warps and at least some machine side warps.

A forming fabric having a set of paper side warp yarns, which interlace with both a set of paper side weft yarns and a set of binder wefts and a set of machine side warp yarns which interlace with a set of machine side weft yarns and the set of binder weft yarns, whereby the binder weft yarns are disposed in groups of at least two, and whereby both binder weft yarns of at least one binder group, in total, form fewer knuckles over the paper side warp yarns than the paper side weft yarns.

An apparatus for forming countertops and the like from a laminated blank bends a side section of the blank to form a substantially vertical back splash and inserts a cove stick into a cove at the bend junction of the blank. The apparatus includes a work-supporting bed for supporting the laminated blank, a bend bar movably mounted with respect to the bed and fluid-actuated pressure means for forcing the bend bar against a side section of the laminated blank for bending the side section into a ver...

Apparatus for forming hollow metal articles such as aluminum reflectors for Luminaires. The apparatus comprises a convex forming punch movable into a complementary hollow magnetic forming coil device. The forming punch is mounted on a base having an annular slot opening at the periphery of the forming punch and being connected to passages in the base for quickly evacuating the air between the workpiece and the punch prior to the magnetic forming operation.

A method of forming a rectangular laminated frame for an electro-magnetic device such as a solenoid includes forming a rectangular laminated frame. Formation of the frame includes winding a strip of material in spiral fashion to produce a generally annular blank and then subjecting the blank to a forming process. The forming process involves applying to the blank pressure in an outward direction at 4 spaced points on the inner peripheral surface of the blank. This applied to outward pressure def...

The invention relates to a forming tool for forming sheet blanks in a diaphragm press of the kind comprising an openable, closed pressure chamber, which is divided in a gas and liquid tight manner by means of a flexible diaphragm. The forming tool is arranged on one side of the diaphragm and a sheet blank to be formed is arranged between the forming tool and the diaphragm. The opposite side of the diaphragm is pressurized by a fluid being supplied at high pressure to cause the flexible diaphragm...

A forming tool for extrusion has a die (5), which has a forming cavity (6) having at least one critical reference value. The die (5) is surrounded by a biasing ring (8), which bears against it with radial pre-stress. The die (5) and the biasing ring (8) have tampered contact surfaces (11) and are displaceable relative to one another. The biasing ring (8) is surrounded by a reinforcement (9), which bears against it with radial pre-stress. The biasing ring (8) and the reinforcement (9) are mounted...

A continuous cold-forming of strip material is used to produce building elements having transverse ribs extending across at least part of the element. The inherent adverse tendency of thin strip to twist and distort as it issues from a transverse rib forming device is prevented by providing a stress relief device for applying a compression load to the transverse ribs immediately downstream of each pair of transverse rib-forming rolls. The stress relief device includes a first roller device and a...

Emulsification is achieved by directing a jet of fluid along a first path, and interposing a structure in the first path to cause the fluid to be redirected in a controlled flow along a new path, the first path and the new path being oriented to cause shear and cavitation in the fluid. A hot emulsion is stabilized immediately after formation by causing the emulsion to flow away from the outlet end of an emulsion forming structure, and causing a cooling fluid to flow in a direction generally oppo...
