Title: Method and apparatus for controlling the speed of ring- or spindle-rails of textile machines
IPC: D01H1/36
Filed: 1971-09-08
Abstract: 1357590 Building motions ZINSER-TEXTIL MASCHINEN GmbH 8 Sept 1971 [8 Sept 1970] 41900/71 Heading D1D [Also in Division G3]  A ring- or spindle-rail drive is controlled by a preset programme in which a control parameter (e.g., size of valve 19) increases with an increasing difference between the prescribed and actual values of rail speed, and the prescribed value of the rail speed is increased (at 48 and 49) at the reversal points of the rail during the deceleration and acceleration phases of the rail. The effect of this control programme is that the period of deceleration and acceleration is reduced. As shown, rail 7 is reciprocated by hydraulic cylinder 9 and direction flow valve 12. The speed of the rail between the reversal points is controlled by prescribed valve transducers 31 or 32 feeding comparator 24 which also receives the actual rail speed via an inductive or tachogenerator-type sensor 22. Comparator 24, acting via PI or PID controller 27, then adjusts the flow valve 19 bring- ing the actual speed nearer to the prescribed speed. Prescribed value transducers are switched by the limit switches 13, 14 and can produce different prescribed values for the rail speeds in its two directions of movement. At reversal of the rail, additional prescribed value transducers 33 and 34 are operated and the additional value is added to the main value at 25 and the increased prescribed value is fed to comparator 24. The additional value transducers 33 and 34 are kept in operation by a substraction stage 25 during the time when the prescribed value speed exceeds the actual speed by a threshold value. In an alternative embodiment, Fig. 3, not shown, a single flow valve (60) controls the direction of movement and speed of the rail. Rectifiers and the limit switches are used to select the control circuit for the flow valve. The increased prescribed value and the main value are produced by one generator (for each direction of movement of the rail), the increased prescribed value being produced upon actuation of the respective limit switch.

[Also in Division F2] A method of manufacturing a cage for a needle bearing of the type comprising a pair of crown sections 21, 22 connected by bars 25 defining roll-windows 24 therebetween and wherein opposite end chordal surfaces 27 form roll guides, comprises the steps of forming a blank 20 with the roll windows extending into each crown section by a pre-end portion 24a of less width than the roller diameter, followed by an end section 24b of width greater than the roll diameter and slotting the flanks of each of said pre-end portions of each window over a radially limited extent to form said chordal surfaces. Both flanks of each pre-end portion are slotted simultaneously by a tool 26 which reciprocates in a plane containing the axis of the cage. The direction of reciprocation is inclined to said axis by an angle " Y "smaller than 90 degrees so that a small triangular portion 28 is left on each flank. If the radial dimension of this triangle is too great the slotting operation is repeated in an oppositely inclined direction to leave a portion 29 having the shape of an inverted isosceles triangle. In a modification the material is removed by a flat-cup shaped grinding wheel, which is thin enough to be partly inserted into a window in the cage blank and then moved in the direction of the axis of the wheel. In a further modification, Fig. 8, the slotting is performed by a tool 226 which reciprocates parallel to the axis of the cage and removes material from each of the pre-end portions to leave lands 229 and 230. The slotting tool is shaped to leave the surfaces 227 either planar or curved.
