| 41 | Centrifugal spinning process and device | US552634 | 1995-11-03 | US5813207A | 1998-09-29 | Reinhard Konig; Friedrich Konig; Georg Konig |
| A centrifugal pot spinning process for spinning yarn of classical character is provided in which either in one stage a fully twisted yarn or in a first stage a partially twisted yarn is spun in a centrifuge (6) and removed from it and, in the case of the partially twisted yarn, the remaining twist is imparted to the yarn in a second stage upon removal while being wound up. A centrifuge (6), a drawing frame (1), a piecing mechanism (2), and a traversing thread guide tube (4) are used. The centrifuge (6) rotates in a space (7) under reduced pressure (pu). Normal air pressure (pn) prevails inside the centrifuge (6) and spinning is carried out under normal air pressure (pn) inside the centrifuge. The reduced pressure (pu) is adjusted in such a way that, during rotation of the centrifuge (6), essentially only the bearing friction of the centrifuge still occurs but the air friction of the outer wall of the centrifuge (6, 35, 45, 53) against the housing (5') is largely suppressed. A vacuum centrifuge (5) is positioned so as to pivot inside the housing (5'). The space (7) between the centrifuge (6) and the housing (5') can be placed under variable reduced pressure (pu). The reduced pressure is adjustable in such a way that, during rotation, essentially only the bearing friction of the centrifuge still occurs but the air friction of the outer wall of the centrifuge is largely suppressed. | ||||||

| A pot spinning method and apparatus wherein a spinning pot rotates during spinning about a vertical axis while an associated yarn guide tube delivers fiber material through an exit mouth of the yarn guide tube onto the rotating inside surface of the spinning pot in the form of a revolving extent of the yarn which also rotates about the axis of the spinning pot. A yarn break or unacceptable changes in quality of the spun yarn can be ascertained extraordinarily quickly if deviations in the duration of the revolution of the yarn extent at the mouth of the yarn guide tube are monitored. | ||||||

| A pot-spinning machine is equipped with a rewinding tube mounted on each yarn guide and with a central, common shogging drive of the yarn guides at one side of the machine. After a yarn break or similar interruption in spinning, in order to be able to initiate the rewinding operation immediately at the affected spinning station while simultaneously continuing the spinning process unchanged at the neighboring spinning stations, the shogging motion of the yarn guide is separated from the motion of the rewinding tube supported on the yarn guide, so that the rewinding tube is then moved only at the forward indexing speed of the yarn guide which is relatively slow compared with the shogging speed and which does not affect the rewinding of yarn onto the rewinding tube. | ||||||
| 44 | Method of and device for the manufacturing of electrical conductors | US39501873 | 1973-09-07 | US3851454A | 1974-12-03 | BEYER J; GOVAERT L |
| A method of and device for manufacturing electrical conductors, in which individual metal wires are assembled to form a strand in a first process phase, the wire strand being subsequently twisted in a second, separate process phase. During this second phase, the strand is fed from a driven spool into a rotating container and is subjected to a first twist. Subsequently, with an unchanged direction of rotation, the direction of movement of the strand is reversed, and the strand is rewound onto the spool, the strand thus being subjected to a second twist. The device for performing this method comprises a drive for a spool, a rotating container with a wire guide, and a winding mechanism with a synchronizing unit.

| 56 | Method of and apparatus for making a mock yarn | US285434 | 1999-04-02 | US6131382A | 2000-10-17 | Friedrich Dinkelmann; Andreas Olbrich |
| To produce a mock yarn which is similar in appearance to a true yarn with respect to the ability to discern the components of the mock yarn after the twist has been imparted to the mock yarn, the rovings or slubbings forming the mock yarn, after drafting separately but parallel to one another in a drafting frame, are subjected separately to condensing and compaction by suction rollers or belts provided with rows of perforations. Thus compacted and condensed rovings are then combined, twisted and wound up as mock yarns. A core thread can be introduced into each roving or into at least one of the rovings upstream of the last pair of drafting rolls or immediately upstream of the condensing unit for a core mock yarn. | ||||||
| 57 | Device for holding and releasing bobbin tubes in a pot spinning machine | US730477 | 1996-10-11 | US5813208A | 1998-09-29 | Karl Koltze |
| A device for holding and releasing bobbin tubes in a pot spinning frame. A bobbin tube holding body has a longitudinal axis, an interior passage along the axis, and a lower end, with the lower end having an outer surface and being adapted to fit within a bobbin tube. A yarn guide for pot spinning is moveably mounted in the passage of the bobbin tube holding body for movement with respect to the bobbin tube holding body along a predetermined path aligned with the axis. A plurality of gripping elements are disposed at the lower end of the bobbin tube holding body concentrically with respect to the axis, and each of the gripping elements are moveable between an extended position extending radially outward of the outer surface of the lower end of the bobbin tube holding body for gripping engagement of the bobbin tube, and a retracted position radially inward of the outer surface out of gripping engagement with the bobbin tube. The gripping elements are moveable from each of their positions to their other position in response to movement of the yarn guide along its predetermined path. | ||||||

| In the spinning unit of a centrifugal spinning machine the yarn conduct (4, 5) mounted between the revolving tube (2) and the yarn spreader (8) is designed so as to open on the side of the rewinding unit consisting of a winding drum (17) and a cartridge holder (18). The yarn conduct opens without displacement of the yarn (28) from its longitudinal axis. This allows to reduce the friction of the yarn (28) against the wall of the yarn conduct (4, 5) during the spinning process and to reduce the friction of the yarn (28) against the wall and the upper end of the spreader (8) during the rewinding process, as well as to bring the rewinding unit closer to the spinning unit. | ||||||
