摘要:
Mold for producing a panel assembly comprising a panel and a gasket, which gasket is adhered to the panel, and extends along at least a portion of the periphery thereof, the mold comprising a first mold part and a second mold part that are formed such that the panel can been closed thereby forming a closed cavity the inner boundaries of which are formed by a first mold surface, a second mold surface and the periphery of the panel, and wherein the second mold part comprises a resilient lip extending along the periphery, the resilient lip being provided for being displaced by an applicator device to provide access to the closed cavity.

A solution casting apparatus includes a drive roller as a conveying means. The drive roller conveys a polymer film peeled from a belt, the polymer film still containing a solvent. The drive roller has corrugation valleys and corrugation peaks formed on a peripheral surface along a circumferential direction of the drive roller. Each of the corrugation valleys and the corrugation peaks has a substantially semicircular cross section. The corrugation valleys and the corrugation peaks are disposed alternately in an axial direction of the drive roller. A pitch Pv between the corrugation valleys and a pitch Pm between the corrugation peaks are in the range of 0.01 to 2 mm, and a height Hv-m from a lowest point of the corrugation valley to a highest point of the corrugation peak is in the range of 0.01 to 1 mm. A curvature radius Rv of the corrugation valley and a curvature radius Rm of the corrugation peak are in the range of 0.1 to 0.5 mm.
摘要:
A method and apparatus for moving along a tube extrusion line. An extruded tube is pushed through the extrusion line, by means of pressure generated by an extruder, to a withdrawal unit that takes over further driving of the tube. In a first-moving along phase, in which the tube has not yet passed a sealing of a calibration cooling unit relative to the atmosphere, the latter is under atmospheric pressure. In a second phase, in which the tube has passed the sealing, the calibration and cooling unit is placed under underpressure. In the first phase, the tube is supported either by internal overpressure or by a mechanical inner guide. A support cylinder extends axially from a casing head of the extruder and extends coaxially into a calibration sleeve in a first section of the calibration and cooling unit. A support plate is disposed between the casing head and an inlet of the calibration sleeve and provides external support for a tube exiting the casing head.

A method is provided for fabricating a surface protection film that has no rolling defects such as blocking or wrinkling when rolled into a roll, and that, after the film is bonded to an adherend, is rolled into a roll, and stored for long periods of time, does not transfer unevenness or fisheyes on the back surface to the adherend. The surface protection film is fabricated as an elastomer by setting the arithmetical mean roughness (Ra) of the surface of a cold roller (4) to no more than 0.2 μm, and the ten point mean roughness (Rz) of the surface of a nip roller (3) to 2-8 μm and the mean distance (Sm) between protrusions and depressions thereof to no more than 90 μm.

A process for manufacturing a plastic hollow body by molding two sheets of molten plastic in a mold including two cavities, the process including: a) two molten plastic sheets are manufactured by extrusion of at least one stream of molten plastic and transverse cutting thereof; b) these sheets are introduced between the mold cavities; c) the mold is closed and the hollow body is manufactured by conforming the two sheets to the mold cavities; d) the hollow body thus obtained is removed from the mold; e) all of operations a) to d) are repeated to manufacture another hollow body from two new sheets; and before, during, or after the transverse cutting operation, the lower portion of the two new sheets is cooled using a specific device that makes possible a local cooling of the sheets in the lower portion.

A valve device for use in a feeding apparatus releases raw material into raw material processing machinery for the manufacture of high-voltage cable. The valve device includes a valve body including a first valve member having a conical shape and including at least one opening extending between a tip of the first valve member and a corresponding base portion of the first valve member, and a second valve member including at least one cover element. One of the valve members is rotatable with respect to the other valve member between a first operating position in which the at least one cover element uncovers the at least one opening, thereby allowing the raw material to flow through the valve device, and a second operating position in which the at least one cover element covers the at least one opening, thereby preventing raw material from flowing through the valve device.
