专利汇可以提供False-twist arrangement专利检索，专利查询，专利分析的服务。并且For the production of synthetic, texturised fine yarns or filaments, a false-twist arrangement is used which comprises a rotary tube provided on the entry side with an annular bead having a rounded, highly polished edge, thread guides being so arranged that the filament contacts the rotary tube only at the highly polished edge of the bead and encloses between the supply and discharge direction an angle greater than 90*.，下面是False-twist arrangement专利的具体信息内容。
1. Apparatus suitable for false twisting of synthetic elements such as yarns or filaments comprising: a. a hollow rotatably mounted tube having an inlet end for receiving the element and an outlet end for exiting of the element, and an inwardly extending annular bead at the inlet end providing an inlet edge having a diameter smaller than the internal diameter of the tube, said inlet edge being rounded and highly polished, b. an inlet roller and an outlet roller disposed, respectively, adjacent the inlet end and outlet end of the tube, for guiding the element first over the edge of the annular bead in contact therewith so that at the inlet end the element contacts only said edge, through the tube and out the outlet end thereof, and so that the element on either side of the inlet edge defines an angle Alpha of more than 90*.
2. Apparatus according to claim 1, the hollow tube having an inlet end face extending radially outwardly from the annular bead and set back from the annular bead in the direction of travel of the element through the tube.
3. Apparatus according to claim 2, the inlet roller being positioned so that the element moves therefrom to the annular bead, radially inwardly and rearwardly.
4. Apparatus suitable for false twisting of synthetic elements such as yarns or filaments comprising: a. a hollow rotatably mounted tube having an inlet end for receiving the element and an outlet end for exiting of the element, and an inwardly extending annular bead at the inlet end and at the outlet end providing an inlet edge and an outlet edge having a diameter smaller than the internal diameter of the tube, said inlet edge and outlet edge being rounded and highly polished, b. an inlet roller and an outlet roller disposed, respectively, adjacent the inlet end and outlet end of the tube, for guiding the element first over the edge of the annular bead at the inlet end in contact therewith so that at the inlet end the element contacts only said edge, through the tube and out the outlet end thereof, over the edge of the annular bead at the outlet end in contact therewith so that at the outlet end the element contacts only said edge, and so that the element on either side of the inlet edge defines an angle Alpha of more than 90*.
5. Apparatus according to claim 4, tHe hollow tube having an inlet end face and an outlet face extending radially outwardly from, respectively, the inlet annular bead and the outlet annular bead, the end faces being set back from the annular beads towards the body of the hollow cylinder.
6. Apparatus according to claim 5, the inlet roller being positioned so that the element moves therefrom to the annular bead, radially inwardly and rearwardly, the outlet roller being positioned so that the element moves from the outlet annular bead to the outlet roller, radially outwardly and rearwardly.
7. Apparatus according to claim 4, the hollow cylinder comprising a body portion and an outlet end member detachably mounted on the body portion, said outlet end member comprising said outlet annular bead.
8. Apparatus according to claim 5, the hollow cylinder comprising a body portion and an outlet end member detachably mounted on the body portion, said outlet end member comprising said outlet annular bead.
9. Apparatus according to claim 6, the hollow cylinder comprising a body portion and an outlet end member detachably mounted on the body portion, said outlet end member comprising said outlet annular bead.
