A method and apparatus for production of couplings for joining together sections of metal tubing, the couplings being of the type comprising sockets having e.g. an annular recess carrying a filler metal, whereby the filler metal comprises a plastic composition which is applied under pressure to a selected internal area of a section of deformable tubing, thereby to form an indentation containing a deposit of plastic composition.

A forming machine to form a sheet of metal to an "S" bend having clamps to clamp the sheet metal, one of the clamps having an anvil about which the sheet metal is folded by a rotatable forming bar to form a first channel and partially form a second channel in the sheet metal after which the rotatable bar is moved clear and a nose on a further former further folds the second channel facing in the opposite direction to the first channel.

Improvement for forming machine by preventing the softened thermoplastic material sheet from dangling and unevenly stretching between a pair of clamp chains, which are extended on a plurality of sprocket wheels to be intermittently driven so that the upper run thereof may receive and keep the sheet stationary in the waiting zone of the machine when the male and female die boxes are contacted for molding and then feeding the sheet between the separated die boxes. The improvement comprises a plura...

There is disclosed a method of controlling, and a control system for, an apparatus, such as a machine tool (100), for forming a straight configured contour, or a straight configured segment forming part of a curvilinear contour, and having co-ordinates in at least two directions (X, Y and Z), said apparatus incorporating a work piece support (102), a contour forming means, such as a milling cutter (107), incremental drives (M.sub.X, M.sub.Y and M.sub.Z) to effect relative movement between said s...

The invention relates to a screen, which consists of one layer of longitudinal threads and one layer of transversal threads and which has a theoretical free area larger than 0%. The longitudinal threads (1) are drawn down in the fabric so that, in the drawn-down points, pockets, or cavities, (3) are formed between the bent-down points. Hereby the fabric or screen has a high draining capacity in combination with good retention properties.

Metal forming process and apparatus are described. The process comprises directing a stream (4) of atomized droplets of molten metal onto a chill surface (5) such that the metal is partially solidified to form a slurry of solidified metal suspended in liquid metal. The slurry is then collected (for example, in a casting mold 7) and then cast or otherwise formed before solidification is complete. It is particularly preferred that the stream of atomized droplets is directed onto a fully solidified...

A forming fabric is disclosed having crimped machine direction monofilament yarns alternating with uncrimped monofilament yarns. The fabric provides optimum stability and seam strength.

Apparatus for supporting a coater blade as used in paper forming. The apparatus comprising a blade support, clamping means for locating the blade against the blade support, and a profile support engaging the coater blade. The profile support is an elongate plate-like member which is clamped adjacent one edge and whose other edge engages the coater blade. Adjustment means is provided to adjust the position of engagement of the profile support with the blade in a direction tangential to the plane ...

A forming machine comprises a rotatingly drivable gripping device (1) for gripping a forming tool (2) and a material plate (3) to be formed, a movable lower slide (6), a first drive (8) for moving the lower slide, a movable upper slide (10, 35) mounted on the lower slide, a second drive (11, 34) for moving the upper slide and a holder (5) for a forming roller (4) supported on the upper slide (10, 35). A control unit (16) is provided for controlling the movement of the forming roller (4) by actua...

A forming fabric consisting of synthetic yarns and intended for use in papermaking, cellulose and similar machines. The fabric comprises two layers, a top layer comprising fine yarns and forming the forming layer proper, and a bottom layer, the wear layer, comprising coarser yarns. The two layers are interconnected by interconnecting yarns which are arranged in pairs in such a manner that in the top layer they replace one another to form a regular pattern, preferably a two-shaft weave pattern, a...
