Abstract: Machinery for welding helical-seam pipe from metal strip. It includes a strip feed, a strip shaper, a seam welder, a pipe output, and a downstream pipe sectioner. The pipe sectioner has a cutter that moves back and forth axially, trimming sections of different lengths from the pipe as it rotates around its axis and leaves the machinery. The machinery also has controls that determine the welding gap between the section of the strip and the beginning of the pipe and how rapidly the pipe cutter moves along the pipe. How rapidly (v) the pipe cutter (47) moves along the pipe is controlled by three detectors. One detector (60 determines how rapidly (v.sub.b) the strip is traveling. Another detector (62) determines the strip-infeed angle (.alpha.) between the section (9) of strip and the axis of the pipe. A third detector, a camera (53), determines the axial deviation of the incision (54) over an angle (.beta.) to the pipe cutter at the circumference of the pipe.

Abstract: To permit gripping of tacky prepreg blanks with stepped surface in an apparatus for the transport of tacky prepreg blanks comprising a suction head, a suction head suspension, a suction pump and a drive generating the movement of the suction head in the vertical and horizontal direction, the suction head (1) comprises a plurality of individually sprung suction tubes (12).

Abstract: An arrangement for manufacturing pressed shapes and similar structures in which loading and unloading arms are driven by displacement drive mechanisms. These displacement drive mechanisms have at least two displacement cylinders with strokes that are shorter than either the displacement path of the loading arm or the displacement path of the unloading arm. There is no force transmission from the cylinders to the loading and unloading arms to provide for minimum use of driving power during acceleration intervals when the loading and unloading arms move from a stationary position to a displacement speed.
