    摘要： The invention relates to an extrusion system for producing cylindrical semi-finished plastic products. The extrusion system comprises an extruder (1) for making available a pressurized plastic melt, at least one extrusion die (7) arranged on the extruder (1) and allowing the melt to leave the extruder (1) as a substantially cylindrical plastic strand (8), a calibration unit (2) which is mounted downstream of the extrusion die (7) and through which the freshly extruded plastic strand (8) passes, said calibration unit cooling the plastic strand (8) and giving it an outer diameter (d), a brake device (3) mounted downstream of the calibration unit (2) and adapted to introduce a variable axial force (A) into the plastic strand (8), said axial force being opposite to the advance of the plastic strand, and a force transducer (9) measuring the axial force (A) introduced into the plastic strand (8) by the brake device (3). The aim of the invention is to improve said extrusion system in such a manner that a better standard quality can be obtained and that it is suitable for the processing of high-temperature resisting plastics. For this purpose, the brake device (3) comprises at least one brake block (16) having a friction surface (19) which brake block is guided so as to be radially movable relative to the plastic strand (8). A radial force (R) is applied to the radially movably guided brake block (16) with its friction surface (19) resting on the periphery of the plastic strand (8) to introduce the axial force (A) into the plastic strand (8). The friction surface (19) has the shape of a grooved section of the surface area of a cylinder.

    摘要： According to the invention, an apparatus is provided for extruding a medical instrument which can be inserted into a human or animal body. The apparatus comprises a device for supplying rod-shaped bodies, an extrusion device comprising a housing, said housing having a surrounding side wall which, at the frontward end as seen in the manufacturing direction, is provided with a nozzle wall comprising a discharge nozzle and, at the rearward end as seen in the manufacturing direction, is provided with a spindle sleeve. The space in the housing between the spindle sleeve, the side wall and the discharge nozzle delimits an extrusion space and the housing is provided with a polymer supply device in the area of the extrusion space. Further, a cannula device is provided which extends in the manufacturing direction and is designed to insert at least one rod-shaped body from the device for supplying rod-shaped bodies into the extrusion space in a predetermined spatial arrangement, which comprises at least one tubular cannula having a rearward supply end as seen in the manufacturing direction and a frontward discharge end as seen in the manufacturing direction, the cannula device being arranged approximately in straight alignment with respect to the discharge nozzle and extending through the spindle sleeve such that its discharge end situated in the manufacturing direction terminates at a distance from the discharge nozzle in the extrusion space.

    摘要： A molded product is produced with a desired cross-sectional area, tension of the molded product to be taken in a press-bonding device is stabilized, and the difference between the production speed of the molded body and the taking-in speed of the molded body in the press-bonding device is absorbed to improve the yield. A resin material 7a for the frame is extruded through an extrusion die 20 at a predetermined extruding speed, hardened in a cooling unit 21 to be a molded product 7 and taken up by a take-up unit 24 at a predetermined speed, whereby a molded product 7 having a desired cross-sectional area is continuously molded. A molded product reservoir 38 is provided between the take-up unit 24 and the press-bonding device 32 to apply a predetermined tension to the molded product 7 to be taken in the press-bonding device 32, whereby the variation in the taking up speed of the molded product 7 by the take-up unit 24 and the variation in the taken-in speed of the molded product 7 in the press-bonding device 32 are absorbed by the molded product 38.
