Definitions

  • the base i.e. the preceding layers
  • the base have unevenness in the form of channels and loose spots where the emerging 1 thread is no longer always pressed sufiiciently on the base by the winding disc. This is for example the case when at one or both sides of the emerging thread in the preceding layers thread crossings exist which then causes an interruption of the pressing-on and accordingly also of the pulling-along of the supplied thread. For this reason all attempts have failed to deposit with such devices smooth threads in rings in order to form a staple round a centre in the form of an endless spiral.
  • the pressure force of the base at the beginning may not exceed a certain predetermined magnitude; otherwise the friction particularly of a fast rotating ring depositing head, becometo'o large, so that the thread material would show spotsof rubbing;
  • the usual cans with spring bottom have moreover the disadvantage that the packed material tends to move upward lowest possible coeflicient of friction.
  • a device for the depositing of thread rings around a centre in endless overlap for the formation of package of thread material comprising in combination: a ring depositing head having a presser plate, a ring depositing plate, a yoke carrying said ring depositing head, fixed columns, guide ledges mounted on said columns and freely guiding said thread depositing head in the vertical direction, and a base in operation rotating relative to said thread depositing head arranged underneath the latter, the weight of said thread depositing head forcing the deposited thread against said relative plate rotating base.
  • the diameter of the package can be chosen so large that the package stands up by itself so that no cans are needed any more; the axially stationary but rotary receiving plate is provided with grooves so that the package can be easily lifted olf by means of special lifting-off forks and can be supplied to a packing point where they receive an enveloping sheath.
  • the new method of laying rings provides a, special contact elements which resiliently forces the thread against the base shortly after its emergence from the ring laying disc.
  • This element may be a spring biased roller or a smooth appropriately bent leaf spring.
  • the principle of this new contact element is to provide a safe contact of the emerging thread with the base and to maintain said contact all round the surface, even if the base is not quite plane, so that the supplied thread is pulled along continuously and uninterruptedly, and is deposited around in a circle.
  • the principle of the aforesaid device-hereinafter referred to as the contact element may be readily explained by the following comparison:
  • the reel thereof When one wishes to deposit a rope or cable in a circle, the reel thereof may be journalled rotatably on an axle, which is carried along by the person laying the rope or cable and walking along in appropriate circles. As long as this person himself treads on the cable, the latter will roll off the reel and keep lying Where it has been pressed into the soil by the feet of the person treading on it, so as to form a circle on the soil. "If, however, the cable is not continuously loaded it has not a sufficient contact with the soil and. is no longer pulled along; that means it will take the shortest path and no longer form a circle when it is not continuously pressed on the soil by the person walking in circles. This is the principle of the use of a contact element on the ring depositing disc for the compulsory formation of rings by a thread of any kind Whatever.
  • the presser plate as well as the ring depositing disc are made of a material of the If desired their frictional surface only may be coated with such a material.
  • Teflon, Perspex (registered trademarks) etc. may be used.
  • a further important condition is that the thread, after being supplied, is conducted to the ring depositing disc Without being hampered; for this purpose provision is made that the thread is guided throughout the hollow axle in a guide tube of a material having the lowest possible coefiicient of friction such as Teflon (registered trade mark) etc. and is then guided in a slightly swept curve to the exit, where it is guided under an acute angle of less than20 towards the ring laying discs directly under the contact element.
  • Teflon registered trade mark
  • FIG. 1 is a front elevation of a thread ring depositing device
  • FIG. 2 is a plan view of the device according to FIG- URE '1,
  • FIG. 3 is a side elevation of a ring depositing disc having a spring-biased roller and a contact element
  • FIG. 4 is a plan view of the ring depositing disc according to FIGURE 3,
  • FIG. 5 is a contact element in the form of a curved leaf spring
  • FIG. 6 is a device with a rotary yarn running-off support
  • FIG. 7 illustrates a package, in which the laying of rings has been carried out beyond the centre.
  • a new improved feature of the device according to the invention consists in that the whole ring depositing head is guided vertically slidable in a yoke 12 with guide ledge 13 between columns 14- so that by its constant proper weight it exerts a constant pressure from above on the receiving disc 16.
  • the receiving disc 16 arranged under the said head is journalled by means of a pivot pin 17 in a bearing bushing 18 of the chassis 15, and is driven by a worm 20 and worm wheel toothing 19.
  • a soft base support of foam material 22 is provided, which has likewise a low coefficient of friction.
  • the receiving disc 16 four grooves 23 are arranged in a square pattern, these grooves extending across the plate 16 and serving for the insertion of special forks for lifting off the staple together with the plate 22 of foam material.
  • the ring depositing head comprises a ring depositing disc 1, which turns in a recess of the presser plate 2 (FIGURES l4).
  • the ring laying disc 1 is journalled with its hollow shaft 3 in the frame 12 and is driven by means of a motor 11 through a cord 9 over cord pulleys and 4.
  • the thread 5 is passed through the hollow shaft 3 in a tube 6 of Teflon (registered trademark) etc. ahead of the contact element 7 under an acute angle of less than downward through the ring laying disc 1.
  • Teflon registered trademark
  • the passage of the thread through the ring laying disc is accordingly effected under an angle smaller than 20 and the Teflon (registered trademark) tube 6 is provided over half the profile up to the end of the exit in order that a minimum friction may result for the thread.
  • suflicient contact with the base is safeguarded when the passage of the thread and the outlet of the thread as well as the whole underside of the thread laying disc are made so smooth, or with so low a friction that the adhesion on the base exceeds the frictional resistance of the ring laying disc.
  • the receiving plate 16 rotates at a desired ratio, which determines the distance of the thread rings 5a from one another (FIGURE 2).
  • the first rings are formed directly on the foam material layer 22,
  • the ring laying plate 1 is arranged eccentrically relative to the centre of the receiving plate. In this manner at each revolution of the receiving plate 16 a layer of overlapping thread rings is built up around the centre thereof, which process is continuously repeated until the desired weight of the staple is attained.
  • the axle 3 of the ring laying disc is slightly inclined in the direction of run of the receiving plate in order that the disc may be higher at A and lower at B than the presser plate 2. In this manner the thread rings can pass it without adhering and without being disturbed.
  • the machines for further treatment may accordingly operate with less breakdowns and standstills and more economical than hitherto.
  • FIG. 7 shows a different pattern of ring deposits.
  • the diameter of the ring laying disc 1 is made so large that its periphery covers the whole area of the coil, and no presser plate 2 is needed.
  • the ring laying disc (FIGURE 2), together with the presser plates 2 may be radially adjusted in the course of operation in its frame 12, in order that the thread rings may be deposited in the package with a radial offset in order that they may bear less strongly at their periphery.
  • FIG. 5 shows an embodiment of a contact element in the form of a leaf spring.
  • This leaf spring 26 is screwed on the hose introducing bracket 25, and shortly behind the outlet of the thread it projects resiliently downward from the ring depositing disc 1 and thus forces the thread on the base when the disc rotates in the direction of the arrow, the deposited thread then describing the same circle about the axis of the ring depositing disc as the thread outlet.
  • this leaf spring contact element when having a well polished sliding surface, serves very well for contacting fine and minimum gauge threads.
  • For smooth yarns such as Orlon, nylon, Terylene, etc. successful tests have been made by coating the contact spring with a material likewise of the lowest possible coefficient :of friction such as Teflon. Provision is also made that the thread guide tube 6 may consist of Teflon in order to reduce the friction of the thread to a minimum.
  • the roller 7 is preferable as a contact element.
  • the roller 7 is preferable as a contact element.
  • contact elements may be arranged in series on a circle.
  • a conveying aid for the thread could be provided by the injection of air.
  • the air required could be supplied by an air catcher built on top of the ring laying disc 1.
  • FIG. 6 moreover shows a device in which a yarn support 39 with a source of yarn 31 is rotatably mounted above the machine frame and is driven from a common shaft 35 in the same sense and at the rotational speed as the receiving plate 16.
