    摘要： A release-controlled pipe and a related manufacturing method comprise several main steps, which are mixing a formulation, first hot melt extrusion and cooling, grinding into pieces, second hot melt extrusion, molding and cooling. The present invention includes the steps of first mixing elastomer pellets and a binder, then pouring the formulation into a melt extruder for extruding and shaping a rod-like extrudate. Then the rod-like extrudate is ground into pieces and placed into a water-filled container and another dry container. The mixture of dry ground pellets, wet ground pellets including water, and a small amount of lubricant is poured into a melt extruder for extruding, and a release-controlled pipe is shaped via a pipe die head and gathered by a winder after cooling.

    摘要： There is provided a plastic extrusion sizing tube having a cylinder with a split along its length to allow for radial expansion and reduction of the sizing tube. The cylinder has holes to allow an extrusion within the cylinder to be drawn to the cylinder by a vacuum outside the cylinder. The cylinder also has extensions on opposite sides of the split with an adjustment screw connecting the extensions. The diameter of the cylinder can be expanded or reduced when the adjustment screw is turned in respective directions. A set screw can be connected to one of the extensions. The diameter of the cylinder can be expanded or reduced when the set screw is turned in respective directions. The diameter of the cylinder can be locked in a desired position when the adjustment screw and the set screw are turned in the same direction. The adjustment screw and the set screw can be located in a flange at one end of the cylinder. The holes in the cylinder can be slots.

    摘要： An extruder die head for producing multilayered tubes made of thermoplastic material exhibits a central annular channel, which is provided with an annular outlet die. Into the outer limiting wall of the channel empty annular slits, which feed a polymer melt and which constitute the smaller diameter openings of truncated channels, formed between the internal and external shells of stacked, conical insert members. To reduce the axial length of the extruder die head, the annular slits, feeding the polymer melts, also empty into the inside wall of the central annular channel. Said annular slits are the smaller diameter openings of truncated channels, formed between the internal and external shells of stacked conical internal insert members.

    摘要： The present invention that also possesses provides a method for producing a seamless tubular film based on cellulose comprising extruding an aqueous cellulose-N-methyl-morpholine-N-oxide (NMMO) spinning solution through an annular die in a spinning bath, wherein the spinning solution forms the tubular film. The film is laterally drawn in an air gap between the annular die and the spinning bath by stabilizing air pressure in the tubular film. The level of hydrostatic pressure from an inner spinning solution formed inside the tubular film extends above the spinning bath, the inner spinning solution comprising an aqueous NMMO solution that supports and intensifies said lateral drawing. The tubular film that has been expanded by the lateral drawing process is passes by a turning point in the spinning bath, and directed out of the spinning bath. The present invention is further directed to devices that are useful in preparing tubular films as well as to tubular films, per se.

    摘要： In an extrusion head and an extrusion method for the production of a tubular multilayer preform the extrusion head includes at least two feed paths for feeding plasticised plastic material from one or more extruders to an annular passage arrangement. The annular passage arrangement includes mutually concentric annular passages forming mutually separate flow paths for the various layers of the preform. An annular gap nozzle has an annular gap communicating with the annular passage arrangement, and at least one flow passage communicates with an annular passage of the annular passage arrangement, for the introduction of a translucent viewing strip. The flow passage communicates with the annular passage in question upstream of the annular gap in the region of separation of the flow paths.
