Abstract: In the case of an opening device for an open-end spinning machine, the rotating opening roller is arranged in a housing with a prevailing vacuum and has one front side which is exposed to the free atmosphere. In the area of this front side the opening roller is sealed off against the housing by means of a labyrinth seal. The labyrinth seal starts in the area of a peripheral combing structure of the opening roller with a first sealing gap and ends with a second sealing gap in the free atmosphere. The sealing gaps are formed by cylindrical collar surfaces of the opening roller and corresponding hollow cylindrical countersurfaces of the housing. In addition, the collar surfaces are provided with fly repulsing notches, whose direction of effect is such that the fly is repulsed at the first sealing gap towards the combing structure and at the second sealing gap, repulsed towards the free atmosphere. The front side of the open roller exposed to the free atmosphere is not covered by a lid.

Abstract: A winding machine having yarn guides for guiding the yarn on a bobbin, mobile supports for supporting each yarn guide, and a driver for imparting reciprocating backward and forward motion to the yarn guides. The driver includes a continuous linear element to which supports for the yarn guides are attached, and a drive rod having a longitudinal axis and which moves reciprocatingly in the direction of the axis. The drive rod is attached to the continuous linear element and thereby drives the yarn guides connected thereto in a reciprocating motion to distribute the yarn on the respective bobbin.

Abstract: A device for making a wire strand with changing twist direction (SZ-stranding) from individual wires, includes a fixed guide (1) provided with bores for receiving the individual wires and a plurality of spaced apart storing disks (4) capable of being driven in changing directions and also having bores for receiving the individual wires to be stranded, and a laying disk (6) capable of being driven via drive disks (7) and transmission members (9), with a drive (8) common to at least a portion of the drive disks (7) being provided, wherein between the drive (8) and the drive disks (7) there is disposed a torsionally elastic shaft (15) having an arbitrary cross-section.

Abstract: A spinning machine has a third guide eye rail, a third balloon-confining ring rail and a traveller ring rail each of which may be operated by a flexible member from a windless drum and the latter can have an electric motor drive. According to the invention, instead of storing all of the points defining the time course of the movement of the rail, a selected number of points such as starting points for the mean path and amplitude, one or more envelopes, and the amplitude or double amplitude of the oscillation superimposed upon the mean path are determined and a corresponding time course is generated. From the time course at given times determined by the oscillation, the maxima and minima of the path is produced by the evaluation and control unit and used to reverse the motor which raises and lowers the respective rail.

Abstract: A method and apparatus for producing randomly variegated multiple strand yarn in twisting together two or more yarns at a plurality of yarn twisting stations. At each station a pneumatic twisting head is disposed in which randomly turbulent air currents are created in a chamber in the twisting head by compressed air flowing into the chamber from a manifold through bores in the twisting head, thereby randomly twisting together two or more yarns in the chamber. The yarns which have been twisted together are taken up over a plurality of traversing drums commonly mounted on a shaft which is driven by an alternating electric current motor controlled by a control device which operates to start and restart the motor on a predetermined cycle including a variation of the electrical input sufficient to result in randomly unpredictable inertia resistance of the traversing drums to rotational speed variation, thereby creating randomly unpredictable take-up of the yarns to produce non-uniform random twist in the yarns.

Abstract: A ring-spinning or ring-twisting machine with a ring rail having rings and travelers for each spinning or twisting spindle. The horizontal ring rail is displaceable on rigid vertical rods, the lower ends of which are connected to vertical stretches of flexible traction elements which lie substantially in the vertical plane of the weight axis of the ring rail.

Abstract: An improved ring spinning machine for making a filled bobbin of yarn, thread or the like comprises at least one ring rail which moves up and down near a plurality of spindles driven by a ring rail drive. A control for the ring rail drive in case of an unforeseen machine stoppage, is arrayed so as to cause the ring rail drive, when it would otherwise drive the ring rail in the upward direction on restart because the ring rail was moving up at the time of shut-off, to reverse so that the ring rail moves downward no later than the time of restart of the spindles, so that the ring rail moves downward after the unforeseen machine stoppage at the beginning of restart thus providing for a safer, more reliable spinning operation.

Abstract: A stranding machine for winding a plurality of wires on a winding drum is disclosed. In the stranding machine, a first and second sun gear are coaxially mounted on first and second shafts, with the winding drum mounted on the second shaft. Power from the driving shaft is transmitted to the first shaft and also to the second shaft via a pair of planet gears meshing with the first and second sun gears, the planet gears being mounted on a shaft fixed to a rotating disk, rotatably mounted on the second shaft. In addition, a stepless variable ratio transmission means also provides rotational motion transmission from the first shaft to the rotating disk. By varying the ratio of the stepless variable ratio transmission means, the rotating speed of the winding drum can be changed.

Abstract: A single-twist wire stranding or bunching machine having a reciprocating flyer traversing the length of a take-up reel and rotating coaxially with respect thereto, such take-up reel being mounted within pivoting means to facilitate easy removal of the reel after it is fully wound with wire. The invented machine comprises electro-mechanical means for automatically controlling the uniformity of the lay length of the twisted wire by correcting for changes in the velocity of the wire being fed into the machine due to wire build-up on the reel or to reversals of the traversing flyer. Additional control means are also disclosed for automatically controlling the points at which the flyer, in its reciprocating motion, reverses direction, thereby minimizing wire accumulations or recesses at the end flanges of the reel.
