摘要： A process and an extruder nozzle for tubular products includes the steps of feeding pressurized material into an extruder nozzle through an inlet, and forcing this material flow through a duct formed between outer and inner nozzle components, and pressing the material flow through an annular aperture at the duct end. Material entering the extruder nozzle is distributed first by feeding into an annular expansion chamber whose cross-section is much greater than the inlet's. When the expansion chamber is completely filled with material whose pressure has become higher than the flow resistance of a homogenizing ring channel having a cross-section narrowed to and connected to the annular expansion chamber then in the homogenizing ring channel the material flow is forced to move across its entering direction, and is homogenized by the relative rotation of surfaces of the homogenizing ring channel. Helical forced movement leads the material to a drawing aperture.

摘要： An apparatus includes an internal and/or an external multiple-stage cooling device arranged coaxially with a drawing orifice of an extruder die and having multilevel tangential outlets for the coolant to stabilize a non-stabilized section of an expanded foil hose by spiral coolant streams. The internal device includes cooling units arranged at axial distances from each other, surrounding the foil section through a gap. Each cooling unit is connected to a coolant supply of selectively adjustable temperature. The external cooling device includes at least two cooling units arranged at an axial distance from each other, surrounding the foil section through a gap. Each cooling unit is provided with tangential inlets and is connected to a coolant supply to supply the coolant of selectively and individually adjustable temperature and/or volume and/or pressure.

摘要： Process for heat transfer between a solid object and a material layer, including the steps of: a) arranging a heat-discharging surface from a heat-receiving surface at a gap (R) for the flow (4); b) generating a speed difference between the surfaces by providing a relative movement thereof; c) increasing the speed (v1) of the flow (4) in the gap (R) compared to the speed of these surfaces (vH and/or vF) by the speed difference; d) maintaining a turbulent flow (4) in the gap (R) and carrying out the heat transfer by this flow (4). In the apparatus, the heat-receiving surface of the solid object (H) is formed on a structural part, e.g. rotor (2), which is relatively movably arranged in a housing (3) compared to the heat-discharging material layer (F). It is provided with a heat-removing unit and/or a heating unit.

摘要： A method and apparatus for cooling extruded plastic foil hose, which is cooled down by driving a pressurized coolant along the internal and/or external skirt of the foil hose. The coolant is fed in the area of a drawing aperture tangentially to the foil hose, and the coolant thus generated is driven as a spiral stream from the tangential inlet to the outlet by a centrifugal force affecting the coolant along the internal and/or external surface of the foil hose, and by the density and pressure differences between various parts of the coolant. The apparatus includes an internal cooling unit equipped with a distribution drum provided with nozzles with tangential inlets. Its external cooling unit has a tangential inlet, which is in connection with a ring channel around the foil hose, delimited by a tubular element.
