    • 专利摘要:
    The invention relates to the processing of polymeric materials by extrusion, and is intended to replace and disassemble the extrusion die nozzles. The purpose of the invention is to reduce the time of changeover of the extrusion head to the production of products of various profiles. For this, the device is provided with a magazine 4 with receiving chambers 5 and means 25 for heating the receiving chambers. Store 4 is made in the form of a drive carousel 20 with radially arranged chambers 5. Store 4 can be made in the form of a horizontally or vertically arranged movable shelf unit. The device has a means for disassembling the spinneret 2. The apparatus greatly simplifies the process of cleaning and replacing the spinneret. 3 hp f-ly, 8 ill.

    devices with a magazine 4 in the form of a shelf for moving the strips of the preliminary element 23, which is reciprocally moving relative to the head 3 by the hydraulic cylinder 24 along guide rails (not shown) until the new nozzle 2 is located before the rod 7 of the cylinder 6.
    3S
    and the final molding is made in the form of a vertical cylinder mounted on the magazine with a rod for pushing the strip to the final molding from the pre-molding strip and feeding the pre-molding bars and the butt to the node for moving the docking bar.
