    摘要： The present invention relates to a method for the production of polyamide 6 with low extract content and a device for it. Here, a melt of non-extracted polyamide 6 is cleaned from monomer and oligomers in a degasification device in vacuum, wherein the vapor being withdrawn from the degasification device by the vacuum generation device is cleaned from monomer, oligomers and optionally water at first in a direct condenser which is operated with liquid ε-caprolactam and subsequently in a pre-separator which is cooled with a coolant, before it reaches the vacuum generation device. A particularly preferable variant of the method envisages the usage of the melt of polyamide 6 with low extract content so prepared in a direct process of spinning into textile fibers and/or filaments.

    摘要： A polymer “cane” extruder is a hand held polymer clay extruder tool made to extrude polymer clay canes with ease. It is designed for home use and comprises of a solid rod and a hollow tube that is made of clear acrylic with marked guidelines. It is an extruder tool that not only extrudes clay but is mainly used for cutting polymer clay cane slices of various uniform and consistent shapes, which includes cylindrical, square, and triangular shapes. This tool aids in holding the polymer canes unique shape and size when compressed and extruded while maintaining the shape of the pieces of polymer cane that are to be sliced off without distorting their original shape. A polymer clay “cane” extruder is very useful for making multi-patterned “sheets” from pieces of polymer clay canes that are combined into one continuous piece. These sheets are used in jewelry articles, such as beads, pendants, bracelets, and neckpieces and/or other arts and crafts related projects.

    摘要： A method for producing a twin screw cylinder provided with or having a wear-resistant coating, in which two bores, which extend essentially parallel to each other and overlap each other, are produced in a cylinder and then two liners are inserted into the bores, the liners having an essentially C-shaped cross-section, continuing from each other in the overlapping region of the bores, forming the inner surface of the bores, and serving as a wear-resistant coating. First, a tubular liner is inserted into a first bore and then is cut to form the C-shaped cross-section in accordance with the diameter of the other bore and after this, a second tubular liner is inserted into the second bore and then is cut to form the C-shaped cross-section in accordance with the diameter of the inner surface in the first bore formed by the first liner.
