Abstract: For coiling a strip-formed material issuing from an extruder, a hollow drum is provided against the inner wall of which the extruded material is fed and which rotates at a speed substantially the same as the speed of the extruded material. Within the outer drum is an inner drum which is stationary or rotates independently of the outer drum. When the supply of material suddenly ceases, the material coils around the second drum without being subjected to damaging strains.

Abstract: In a device for treating material at high temperature and high pressure which includes a high pressure cylinder built from a tube and a prestressed, force-absorbing wire or strip sheath wound around the tube, with end closures projecting into the cylinder and a press stand for holding the end closures, the cylinder is provided with longitudinally extending cooling channels either running along the inner wall of the sheath or at an intermediate position within the sheath, adjacent to the inner wall thereof.
