    摘要： Method for the cleaning of spinning devices with a plurality of spinning apertures for the output of molten plastic. With the spinning device in operation, individual dirt-contaminated and/or clogged spinning apertures are closed with plugs, these plugs-consisting of at least in part of at least one oxidizable substance. The spinning device is subjected in the course of its cleaning to a pyrolysis treatment for the breakdown of residual plastic. The spinning device is subjected to an oxidative treatment, so that the oxidizable substance is oxidized.

    摘要： A method for forming a resin including the steps of forming a resin by using a resin forming nozzle device while supplying thereto a surface lubricant for mold release, having a viscosity of 0.1 to 1,000 cP during use and a surface tension of 40 dyn/cm or less at a temperature of 25.degree. C., wherein the resin forming nozzle device includes the surface lubricant being continuously introduced to a nozzle face having the discharge openings of resin extrusion orifices, the device further including a feed section for supplying a surface lubricant from the outside, and one or more grooves formed on said nozzle face in positions adjacent to the discharge openings of the nozzle face so that the grooves have a width of 10 to 3,000 .mu.m and a depth of 10 .mu.m or greater and at least one end thereof communicates with the surface lubricant feed section.

    摘要： A resin forming nozzle device is disclosed. This resin forming nozzle device is one in which a surface lubricant having mold release properties is continuously introduced to a nozzle face having the discharge openings of resin extrusion orifices, and comprises a feed section for supplying a surface lubricant from the outside, and one or more grooves formed in positions adjacent to the discharge openings of the nozzle face so that they have a width of 10 to 3,000 .mu.m and a depth of 10 .mu.m or greater and at least one end thereof communicates with the surface lubricant feed section. When a resin is formed by using this nozzle device while supplying thereto a surface lubricant having a viscosity of 0.1 to 1,000 cP during use and a surface tension of 40 dyn/cm or less, neither oligomers of the resin nor degradation products of the surface lubricant accumulate on the nozzle surface. Consequently, stable resin forming can be performed for a long period of time without causing breakage of the filaments.
