An automatic operating device is provided for carrying out at least one operator action. The automatic operating device has at least one movable robotic arm, which can be coupled selectively to one of a plurality of exchangeable tools in order to selectively carry out a plurality of operator actions during a start-up and/or during a maintenance interval and/or during thread production. Thus, a high level of flexibility in the automated operation of the melt spinning device is ensured.

An extruder which can be applied to various types of resin and elastomer without having to replace a die is provided. An extruder of the present inventions has: a barrel to which raw material, that is raw elastomer or raw material resin, is supplied; a screw that is driven to rotate in the barrel in order to process the raw material together with the barrel; and die 5 that is provided at a discharge point of the barrel and that discharges the raw material that has been processed. Die 5 includes first flat plate 11 having at least one first hole 13 and second flat plate 12 having at least one second hole 14, wherein first flat plate 11 and second flat plate 12 are arranged adjacent to each other along longitudinal axis X1 of the barrel, and at least either first flat plate 11 or second flat plate 12 is movable relative to the other flat plate such that an overlapping part of first hole 13 and second hole 14 can be varied.

Thermoplastic articles are molded from thermoplastic polyurethane compounds including blends of aromatic polycaprolactone thermoplastic polyurethane and aliphatic polycaprolactone thermoplastic polyurethane. The thermoplastic articles can have enhanced stability against exposure to ultraviolet (UV) light relative to thermoplastic articles molded from thermoplastic polyurethane compounds including only aromatic polycaprolactone thermoplastic polyurethane as the thermoplastic polyurethane component. Additionally, the thermoplastic articles can have good stain resistance, good clarity (i.e., low haze), and other desirable properties.

A hybrid-type door outside belt for a vehicle utilizes different materials for a skin layer of a skin body that is mounted to an upper end of a door panel and a main wing that is moved by contacting the door glass, the skin layer of the skin body being made of a material having excellent scratch-resistance, and the main wing being made of a material having excellent compression set (deformation).
