Definitions

  • the invention relates to winding carrier for freshly spun threads of artincialvsilk on which the package formed by the threads remains during the wet aftertreatment and the subsequent drying and which permits the necessary shrinking of the threads.
  • the shrinking is rendered possible by Winding the thread package on a reel-like carrier of a larger diameter than its nal diameter, and then reducing said diameter as required.
  • the thus loosened windings must be so arranged on the winding carrier or spool of reduced diameter that in subjecting the thread package, while still in position on the carrier, to an after-treatment the resistance opposed to the flow of treatment liquid is uniform between all the thread windings inclusive of those at. the sides of the package adjacent the flanges of the spool. Consevquently.-the spool must have a certain sealing elect with respect to the sides of the thread package.
  • the carrier constructed according to this invention responds to these requirements and is an improvement on the winding carriers disclosed in my United States Letters Patent No. 2,074,217.
  • the supporting rods and their locking members which allow a larger or smaller diameter or the package to be alected, remain on the spool and pass with the latter through all the baths of the aftertreatment andthe drying ovens.
  • One object of the invention is, while maintaining the advantages of afore-mentioned carriers, to separate the movable parts conventionally remaining on the winding carrier or spool from the spools proper and to attach said parts permanently to the spinning machine.
  • the advantage results that while the supporting area of each winding carrier is increased, a much smaller number of spool carriers is required to be installed in the spinning mill.
  • the use of these spool carriers thus presents economic advantages.
  • the advantages inherent to the present invention over known constructions are the shape of the package, the manner in which the package is transferred 'from the larger dimensioned spool carrier to the smaller spool, which transfer does not cause any alteration of the shape of the pack- .age nor a, pinching of the threads, and the continuously effective sealing adjacent the ends ofthe package which is present in every stage of the aftertreatment.
  • FIG. 1- is a plan view of a spool with the package of artificial silk wound upon it;
  • Fig. 2 is a longitudinal sectional view of the empty spool on the line II-II of Fig. 3;
  • Fig. 3 is a part of a transverse cross-section of the empty spool
  • Fig. 4 is part of a. transverse cross-section of the spool and of the supporting members inserted therein;
  • Figs. 5 and 6 show in longitudinal sections two different constructional examples of a spool and spool holder or spool carrier.
  • FIG. 2 illustrates the empty spool in a longitudinal section.
  • the main body of the spool is composed of a pair of end rims Ib and Ic spaced apart and a plurality of bars 4 extending longitudinally between said rims.
  • the bars 4 are slightly spaced apart circumferentially leaving slots 2 which open at one end through rim Ic at 2', Figs. 2 and 3. Through these slots 2 pass longitudinal thread package supporting elements 3 (Fig.
  • the longitudinal elements 3 are provided in a large number and are preferably of generally T-shaped cross-section so that the supporting surface for the silk thread is as large as possible and forms an almost continuous cylindrical surface. It is not necessary that the enlarged heads of theA supporting elements 3 can pass through the circumferential wall of the spool S, but owing to enlarged openings 2a in the end rim lc (Fig. 3), the supporting elements are introduced endwise into the interior of the spool.
  • the bars 4 of the wall of the spools between which the slots 2 extend as well as the heads 3a of the elements 3 of the spool holder may therefore be amply dimensioned, the enlarged heads 3a of the supporting elements 3 being situated on the outer side and the .bars 4 on the inner side of the spool S.
  • the shoulders on the radially inner parts of bar portions 4 are designated by numeral 2
  • FIG. 5 illustrates a modified constructional example in which the supporting members 3 are held in the desired position by conical camming y ports 5, and 5a and a locking screw thread 6.
  • the spool has openings at both ends corresponding to openings 2a of Fig 2, which would allow the members 3 to be inserted and removed from either end.
  • Numeral 1 denotes the shaft of the spinning machine on which the spool is to be placed, and 8 is the spool carrier fixed to the shaft 1 and which is constructed according to the invention as an adjustable reel.
  • the supporting members 3 project through slots 8b of a drumshaped part of the spool carrier 8.
  • a spool S with identical flanges is slid until the ends of the bars 4 engage the disc-shaped rear portion 9 of the spool carrier which constitutes a spool winding position defining abutment means.
  • the knob I0 together with the conical parts 5, 5a is thrust inwardly and is locked on the thread 6 by turning the knob I0.
  • the conical parts 5, 5a cause the longitudinal members 3 to be urged in radially outward directions and at the same time hold the spool I, la in axiallytrue winding position.
  • the stroke may progressively be shifted along the spool or both kinds of winding may be used simultaneously or alternately.
  • the package W no longer bears on the supporting members 3 but is held in position by its contact with the anges I, la and bears on the parts 4 of the spool only in the course of the after-treatment; thus the package is permitted to shrink unrestrictedly to the exf tent by which the circumference formed bv the parts 4 is smaller than that of the supporting members 3 of the spool carrier in their radially outward position.
  • the helical spring II urges, the longitudinal members 3 together with the spool in the forward direction into bearing engagement with the flange or abutment 8a of the spool carrier, uso that then this spool is in spool-exchanging position.
  • the knob I0 together with the conical parts 5 and 5a are urged to the right as seen in Fig. 5.
  • the members 3 engage at Ilrst the end rims on which flanges I, Ia are formed and concomitantly force the spool endwise towards the shaft 1 luntil the spool abuts against the flange 9 of the spool carrier.
  • FIG. 6 A modified example of the invention is illustrated in Fig. 6 which differs from that shown in Fig. 5 inasmuch as locking balls are provided instead of the locking thread.
  • Fig. 6 shows the device in the position which exists during the windlng.
  • the supporting members 3 are in their outward position and they form the larger supporting circumference for the package W.
  • This spool also has openings at both ends for insertion and removal of members 3.
  • the conical parts 5 and 5a are hollow and both are provided with interior conical faces.
  • Balls I3 (only one being shown in Fig. 6) lock the conical parts to the shaft part I4 xed to the spool carrier as a spring I5 urges the balls against the narrower portion of the interior cone.
  • a pull is exerted on the knob I6 in the outward direction, i. e., towards the left in Fig. 6.
  • the hub I1 forces the balls out of the locking position, while the rim I8 abuts against the end wall I9 forming one part with the cone 5, whereby the conical parts 5 and 5a are displaced towards the left in Fig. 6 and the tongue parts I2 pull the supporting members 3 in the radially inward directions.
  • the members 3 are guided between the end disk of the spool carrier 8 and the rim 8a.
