Definitions

  • This invention relates to spools for collecting filamentary material. More particularly, the invention relates to a novel textile spool having a flexible head and designed to facilitate removal of yarn therefrom in the form of a hank or skein.
  • Waste spools In textile practice, it is often necessary to collect the first lengths of yarn undergoing processing which may be of substandard quality onto separate spools called waste spools. Waste spools, in one application, are used on drawtwister machines employed to draw and twist yarn in textile processing.
  • Drawtwisters in brief, comprise a frame with multiple yarn drawstwist positions, and include a support member adapted for mounting a supply bobbin packaged with yarn thereeon.
  • the yarn from the supply bobbin travels continuously from a driven feed roll assembly to a draw roll means driven at a faster rate of speed to stretch the yarn therebetween.
  • the yarn travels to a twisting means for twisting the drawn yarn before it is finally taken up on a shipping bobbin.
  • the twisting means includes a waste spool for collecting the initial lengths or outer wraps of yarn from the supply bobbin which may have been exposed to light, soiled, or damaged.
  • Another object is to prow'de a flexible yarn waste spool adapted to be used on textile yarn drawtwisters and other textile machinery where the initial yarn is similarly collected.
  • Another object is to provide a spool adapted for holding windings of yarn, said yarn being easily removable therefrom en masse Without being unwound.
  • the invention comprises a ring-like spool provided with flanges arranged at pposite ends of a frusto-conical body portion. At least one of the flanges is formed in the configuration of a flap which is resilient and segmented. A slot is defined in and extends across the yarn engaging surface of the body
  • FIGURE 5 is a perspective view shovw'ng the method of removal of the hank of yarn from the spool;
  • FIGURE 6 is anelevation view showing a spindle adapter which may be used in conjunction with the novel spool; 7
  • FIGURE 7 is a side elevation view, partially in section, of a modified construction of the spool.
  • FIGURE 8 is a broken section showing the spool reinforced with a rigidizing ring.
  • flexible spool 1 comprising the invention and its manner of operation are shown in the drawing, FIGURES 18.
  • flexible spool .1 is constructed of a plastic material capable of recovering original size and shape after deformation, such as polyurethanes, polyesters, rubber, polyolefins, polyamides, and the like.
  • Spool 1 is ring-like to permit mounting on a spindle 2 of such as a yarn twister device 3 shown in FIG. 4.
  • Spool 1 has flanges 4, 5 arranged at opposite sides of a frusto-conical body portion or face 6 upon which yarn is normally wound. The diameter decreases from flange 5 to flange 4 so that yarn wound tightly therearound can be pushed or slipped across face 6 toward the reduced diameter portion thereof to loosen its hold on the tapered surface.
  • Flange 4 is molded in the configuration of a springy flap that yields to pressure and returns to its original shape once the pressure is removed.
  • Flange 4 is also, preferably, segmented. That is to say, that the flange is not continuous circumferentially.
  • Flange 5 can be more rigid than flange 4, if desired, and includes a radially inwardly projecting lip 7 at its outer side thereof to permit mounting of the spool on an adapter having a circular disc. Lip 7 is designed to snap over and to grip a circular disc.
  • a disc-adapter 8 is shown in FIG. 6 mounted on spindle 2. 1
  • At least one transverse slot 9 is formed across face 6 of spool 1 and, as shown in FIG. 3 extends into part of flange 5. Slot 9 is aligned with a space provided between the segments of flange 4. Spool 1 may be reinforced with an annular rigidizing ring 10 as is shown in FIG. 8,
  • spindle 2 of twister device 3 is provided with a separate or integrally formed disc-adapter 8 so that the spool could be securely clamped to the disc by means of lip 7.
  • the. spool may be constructed without lip 7 and in this case the spool would be attached directly to the portion.
  • FIGURE 1 is a plan view of a novel spool of the present invention
  • FIGURE 2 is a bottom view of the same
  • FIG. 3 is a side View of thethereof shown in section
  • FIGURE 4 is an elevation view showing the novel twister machine
  • Yarn 11 is led, from a drawn assembly incorporated on a conventional drawtwister (not entirely shown), through a traveler guide 12 mounted on a reciprocable ring 13 and then wound around the spool 1.
  • Reciprocable ring 13 is at start-up positioned in the horizontal plane of spool 1 and is not operated while the spool is driven by a conventional belt means and power assembly 14 including a whirl 15 mounted on spindle 2. After a predetermined amount of yarn 11 is taken up on spool 1, the ring 13 is reciprocated.
  • v Upon upward movement of ring 13 away from spool 1 the yarn 11 is wound about a take-up bobbin 16 positioned on spindle 2.
  • Slot 9 is, preferably, extended into flange to allow the'stem of'tool 17 to be conveniently inserted into slot 9. It will'be noted that slot 9 is aligned with the space between adjacent ends of adjoining segments of flap 4. With such an arrangement, the yarn is quickly freed at the point between the segments because the ends of the segments which are contacted bend readily.
  • a spool of the type embodying the invention results in quick .and facile removal of yarn in a condition to permit subsequent economical sale thereof.
  • the spool 1 may also be constructed with a metal body and a springy flange attached thereto as shown in FIG. 7; and, the flange 4 may be continuous, discontinuous, or segmented.
  • a yarn holding spool comprising,
  • I (d) means defining'a slot in said outer face.
  • a yarn waste spool of unitary construction comprising,
  • segmented springyflap means arranged adjacent to the reduced end of. said frusto-conical outer face withspaces provided between the segments,
  • said flange means having a radially inwardly ex tending yieldable gripping lip for mounting said spool
  • (6) means defining a slot formed in said outer face "andextend-ing into said flange means
  • a yarn twister device comprising in combination,
  • (/1) means defining a slot formed in said outer face and extending into said flange means
  • a yarn holding spool comprising,
  • springy flange means arranged adjacent to the reduced end of said frusto-conical outer face
  • (d) means defining a slot in said frusto-conical outer face.
  • a yarn holding spool comprising,
  • said ring-like body and said flange means formed adjacent to tie larger diameter end of said frustoconical outer face being made of a rigid material and said springy flange means arranged adjacent to the reduced end of said frusto-conica-l outer face being made of a plastic material.
