Definitions

  • the invention relates to a thread-tensioning and balloon control or breaking motion for unwinding yarn from crosswound or other supply packages on textile machines, particularly on weaving machines.
  • a circular, supporting, rimlike means is provided to be positioned coaxially to and adjacent the package unwinding end, and stands approximately normal to the package axis. It is provided internally with a plurality of pivoted, spring loaded tensioning members. These are spaced circumferentially of the supporting rimlike means and lie tangentially on the outer surface of the package to restrain and inhibit the ballooning tendencies of the yarn being drawn from the package.
  • the object of the invention is to create a motion or device which will overcome these difficulties and allow more perfect unwinding of the yarn from the supply packages at constant yarn tension.
  • This desired object is realized by providing a circular supporting rim or supporting means, said rim surrounding the supply package at its unwinding end, standing at least approximately normal and coaxial to the bobbin axis, and being provided at the inside with a plurality of springloaded tensioning members such as wires or needles, flat springs or the like, said tensioning members being spaced about the circumference of the rim and lying tangentially on the corresponding outer diameter or surface of the supply package.
  • FIG. I is a side view of the threadtensioning and balloonbreaking motion, according to the invention.
  • FIG. 2 is a partially cutaway front view of the motion as per FIG. 1.
  • FIG. 3 is a partial view of the mechanism of FIG. 2, drawn partially in section and on a bigger scale.
  • FIG. 4 is a section along the line IVIV in FIG. 3.
  • FIG. 5 is a section along the line VV in FIG. 3.
  • FIG. 6 shows an arrangement comprising two units according to the invention, in magazined relationship.
  • the motion or device incorporates a support 1, carrying a crosswound bobbin or other supply package 2, a holding arm 4 mounted by means of a crosshead 3, and clamped at a suitable position by a clamping screw 5.
  • the other end of the arm 4 is fork shaped and carries a swivel pin 6 extending through a bracket 16 of the rim 7.
  • the whole rim is therefore pivotable around the swivel pin 6, in the direction of the arrow 22, between a working position, as shown by full lines in FIG. 1, and a swungout position as indicated by dashdotted lines in FIG. 1, to allow, for example, for a new package to be put on.
  • Clamping members (not shown) can be provided to fix the rim in its two end positions, if required.
  • the rim 7 consists virtually of two parallel rings 25 and 26 connected to each other, FIGS. 4 and 5.
  • a setting ring 21 which can be rotated in a limited way in the direction of the circumference, and the position of which can be fixed by means of one or more screws 24 leading through slots 23 in the ring 25.
  • the two rings 25 and 26 are held together by a number of pins 10 arranged in regular distances from each other.
  • a needle holder 9 is pivotally borne on each pin 10.
  • each of the needle holders 9, which are preferably all alike, is provided with two ten sioning needles 8, inserted side by side. There could, of course, be more than two needles or only one needle inserted into the needle holder.
  • 25 needle holders 9 are provided at equal distances about the rim, but the number of needle holders 9 could also be more or less.
  • needles 8 it is possible to use other types of tensioning or balloon controlling members, such as flat springs or the like.
  • a tension spring 11 is connected to each needle holder 9 and the other end is fastened to a pin 27 of the setting ring 21. Due to the tension of the springs 11 the needles 8 are lying tangentially against the surface of the supply package 2. By moving the setting ring 21 in relation to the two rings 25 and 26, the tension of the spring 11 and, therefore, the pressure of the needles 8 on the supply package can be adjusted.
  • a tensioning ring or needleretracting ring 13 is provided on the outer circumference of the two rings 25 and 26 which can be moved in the direction of the circumference in relation to the two rings 25 and 26 by means of a handle 14.
  • the inclination of the needles 8 as shown in FIG. 2 and 3 is in accord with the corresponding outer diameter of the supply package 2.
  • the needle holders 9 are shaped in such a way that when pivoting on their pins 10 they transfer the force of the tension springs l l to the end of the needles 8 and apply practically constant pressure onto the supply package 2 which is virtually independent of the diameter of the yarn bobbin.
  • FIG. 6 shows how this uninterrupted filling yarn supply can be achieved when using the motion which is the subject of the invention.
  • Two swivel pins 20 and 30 are arranged on a fixed support 29.
  • the support is arranged on a ground plate 33 which is provided with a guiding eyelet 34 for the filling yarn.
  • a clamping bracket 31 with a support 1, the cross head 3 and the holding arm 4 with the rim 7 can be pivoted around the pin 20.
  • a clamping bracket 31', a support 1', a cross head 3 carrying a holding arm 4' with a rim 7 can be pivoted around the pin 30.
  • the tail 32 of the supply package 2 is connected to the nose [7 of a new full supply package 18, whereby the yarn is guided through the rim 7 and lightly held by a holding or clamping device 19.
  • the thread is pulled out of the holding device 19 and leaves the rim 7. The yarn will then be unwound from the bobbin 18.
  • the empty bobbin 2 After swinging out the empty bobbin 2 around the swivel pin 20, lifting up the rim 7 and opening the needles 8 in the described manner by means of handle 14, the empty bobbin 2 can be replaced by a new full package.
  • the nose of the yarn of the new package is to be connected to the tail of the package 18 just put into operation. This process is repeated whenever a supply package is exhausted to ensure an uninterrupted filling yarn supply.
  • Additional devices can be provided to fix the clamping brackets 31 and 31' respectively, on their pins 20 and 30 in their two end or extreme positions, i.e. in working position and swungout position.
  • the unwinding of yarn from the supply package is effected without formation of a balloon and that the yarn is held under the light pressure of at least one tensioning needle at any moment during unwinding and is thus held under constant tension. The forma tion of loops and snarls is thereby avoided.
  • a threadtensioning and balloon control motion for the unwinding of yarn from supply packages on textile machines, particularly on weaving machines characterized in that, a rimlike supporting means is provided on a holding arm, said supporting means surrounding the supply package adjacent its unwinding end and standing at least approximately normal and coaxial to the package axis, pivot pins spaced about the supporting means and holders pivoted on said pins, at least one springlike tensioning member fixed in each said holder and so arranged at spaced intervals circumferentially of the rimlike supporting means that they lie tangentially against the outer 0 justment of said springs.
  • a threadtensioning and balloon control motion according to claim 1, including means in the rimlike supporting means for simultaneously pivoting said tensioning members from their operating position to an ineffective position wherein the tensioning members are withdrawn and lifted off the surface of the supply package.
