    摘要: A device to produce strand-shaped products from thermoplastic or elastomer materials comprising a paste extruder having a specially implemented internal volume defined by a cylindrical internal mandrel (2) and an external cylinder mantle (1). The polymer material is charged in the internal volume. The polymer raw material may be provided as a powder or granulate or as material cores produced in a separate precursor process using the same device. The polymer mass is melted by heating and discharged using an expulsion piston (3). A static mixing line (5) is provided in the outlet area, in which penetration of the melt flow occurs due to special shaping and uniform mixing of the molten material. A homogeneous material flow is achieved, which is supplied via a melt duct to a conventional longitudinal or transverse extrusion head (4).

    摘要: In a process for the irradiation of strand-shaped irradiated material (19; 19a-e), in particular cable insulation or sheathing (31) capable of being cross-linked by irradiation, or tubes, hoses, or profile elements capable of being cross-linked by irradiation, with electron beams impinging transversely to the longitudinal axis of the irradiated material (19; 19a-e), which strike the irradiated material (19; 19a-e) from two fixed irradiation directions (R1, R2), located at an angle to one another which is other than zero and for preference is a right angle, a uniform irradiation is achieved in a simple manner in that a scanned electron beam (17) is created from an electron beam (11) in a scanner (12) by means of a scan device (13), which by means of a temporally-actuated back-and-forth slewing movement in a prescribed angle range creates a radiation fan transversely to the longitudinal direction of the irradiated material, and that the scanned electron beam (17) is deflected by a deflection magnet (16, 16′) arranged between the scan device (13) and the irradiated material (19; 19a-e) in such a way for each scan angle of the irradiation field that it impinges on the irradiation material (19; 19a-e) to be treated from one of the two fixed irradiation directions (R1, R2).

    摘要: The invention relates to a method for the production of at least one longitudinal section of a catheter, wherein the method comprises the winding of film, and the film is provided in the form of strips, the film strip is wound in the manner of a screw such that the side edges of the film strip extending in the manner of a thread overlap the film strip, and further a bonded connection is created in the overlapping region such that the longitudinal section has a closed and at least fluid-tight surface. The invention further relates to a catheter produced according to the method, and a device for carrying out the method.
