Definitions
- the invention relates to a bobbin body, more particularly to conical bobbin bodies for yarn.
- the bobbin body according to the invention is suitable, for example, for supporting the weft thread in looms for weaving of the gripper shuttle type wherein the yarn spools remain outside of the shed and are stationary during Weaving.
- the bobbin body according to the invention is conical and has circumferential grooves, each groove having, at the side of the reduced diameter of the body, a wall portion which is substantially normal to the longitudinal axis of the bobbin body, the rest of the wall of the groove being inclined with respect to the longitudinal axis of the bobbin.
- This particular configuration of the grooves causes the last windings to stay on the bobbin in their original position until they are unwound and not to slip or move axially prior to being unwound.
- This has shown that this is true not only for parallel but also for cross wound bobbins.
- the last windings of cross wound bobbins are held in place by sagging into the grooves over which the yarn passes at a slant and are held by friction on the edges formed by the intersection of the wall portions which are normal to the axis of the bobbin and the inclined wall portions of the grooves, but are easily unwound. Since the last yarn windings remain in their initial position until they are unwound, formation of loops and twisting is prevented and, if the spools are used on looms, faulty weaving or thread breakages are avoided.
- the grooved bobbin is formed by a perforated conical tube permitting passage of fluid for treating the yarn, for example for damping, bleaching or dyeing.
- the bobbin which has been wound can be treated andthereupon immediately placed on the weaving machine, respooling yarn being unnecessary.
- each circumferential groove on the conical surface of the bobbin has a radial wall portion at the small diameter side of the groove and has a slanted wall portion forming the bottom of the groove, there being an annular spacing portion formed by the conical surface of the bobbin between the grooves.
- the axial extensions of the slanted portion and of the spacing portion are substantially equal. If holes are provided, these are placed in offset relation on the slanted portions and on the spacing portions.
- the bobbin according to the invention is preferably made of a synthetic substance which is heatproof up to at least 212 F., for example, a polyvinyl acetate.
- a slot is provided in the tube forming the bobbin for attaching the thread end.
- the slot is preferably placed at one end of the tube and on the outside thereof and does not extend to 3,138,345 Patented June 23, 1964 "Ice the inside. This prevents entry of liquid treating agent into the slot as it would be the case if the slot would extend to the inside of the tube.
- the bobbin according to the invention although provided with a thread end holding slot, can therefore be used for damping, bleaching and dyeing, and respooling of the yarn after treatment is not required. Since the slot does not penetrate to the inside of the tube, the latter is not weakened as it would be the case if the slot would extend all the way through the tube wall.
- FIG. 1 is a side view of a bobbin body according to the invention.
- FIG. 2 is an end View of the bobbin body shown in FIG. 1, looking from the left side of FIG. 1.
- FIG. 3 is a longitudinal sectional large scale view of a portion of the bobbin body shown in FIG. 1.
- FIG. 4 is a longitudinal sectional View of a portion of a modified bobbin body.
- FIG. 5 is a side view of a bobbin body having a thread end attaching means according to the invention.
- FIG. 6 is an end view of the bobbin body shown in FIG. 5, seen from the left side of FIG. 6.
- FIG. 7 is a longitudinal sectional view of a portion of the bobbin body shown in FIG. 5.
- FIG. 8 illustrates a modification of the thread end attaching means of the bobbin body shown in FIG. 5.
- FIG. 9 is a side view of the left end portion of the bobbin body whose left end is shown in FIG. 8.
- numeral 1 designates a hollow conical bobbin body having a conicity angle A of 4.
- the outer surface is provided with a plurality of circumferential grooves 2.
- Each groove has a wall portion 4 at the small diameter side of the groove, i.e., the side facing the small diameter end 13 of the bobbin body.
- the wall portions 4 are normal to the longitudinal axis 5 of the bobbin body whereas the rest 6 of the wall of each groove is conical, i.e. at a slant with respect to the longitudinal axis 5, the conicity angle being greater than the angle A.
- the axial extension of the inclined wall portion 6 of the grooves 2 amounts to about one half of the axial spacing '7 between the wall portions 4 of two adjacent grooves, i.e., to approximately one half of the axial distance between the bottoms 8 of two adjacent grooves.
- a plurality of radial holes 11 are provided in each of the sections of the bobbin body confined by the surface portions 9, affording passage of treating agents, particularly dyeing liquids.
- the sections of the bobbin body confined by the wall portions 6 are provided with a number of holes 12 equal to the number of holes in the sections confined by the surfaces 9, the holes of adjacent sections being offset. Only one hole 11 is illustrated. The positions of the other holes 11 and of the holes 12 are indicated by crosses.
- An annular groove 13 is provided adjacent to the small diameter end 3 of the bobbin body which groove is free of holes.
- Two coaxial annular grooves 15, free a of holes, are provided at the left end 14 of the bobbin body.
- the grooves 13 and 15, which have a radial wall portion at the small diameter side and an inclined wall portion extending from the radial wall portion to the large diameter end of the bobbin body, provide a particularly good hold of the last windings of the yarn wound on the bobbin body.
- a shallow annular groove 18 of rounded configuration is provided which serves for winding a few windings of yarn onto the bobbin body prior to the spooling operation.
- the walls 16 of the holes 11 and 12 are preferably conical as seen in FIG. 3.
- the bobbin body 1 is made of synthetic material which is heatproof up to at least 212 F.
- the wall portion at the small diameter side of an annular groove 2' is at an angle B of preferably not more than 10 with respect to a radial plane 19. If the angle B is greater than 10 the groove cannot have the desired yarn retaining etfect.
- the bobbin body illustrated in FIGS. 5 and 6 has three slots 31 at the large diameter end 14 for attaching the end of the yarn.
- the slots extend from a location 32 of the circumference 33 of the bobbin body to a location 34 of the circumference without extending through the inside surface of the tube forming the bobbin body.
- the innermost portion 35 of the groove 31 is spaced from the interior surface 36 of the conical tube forming the bobbin body.
- a slot 31 is provided at the end 14 of the bobbin body 1 which slot is plane, secantlike extending through the end 14 of the bobbin body.
- This configuration of the slot permits cutting of the slot into the finished bobbin body at any time.
- the slot leaves a thumblike portion 41 at the outside of the bobbin body whose end does not extend to the end 14 of the bobbin body. This affords placing the thread end first at the outermost portion 42 of the slot plane and subsequent movement of the yarn into the slot 31.
- slots for holding thread ends may also be provided at the small diameter end 3 of the bobbin body. Only one slot may be found sufiicient.
- each groove having a substantially radial annular wall portion toward the small diameter end of the bobbin body and extending substantially normal to the longitudinal axis of the bobbin body,
- each groove being a wall portion inclined toward the large diameter end of the bobbin body and relative to said conical outside surface
- said spacing surfaces having the same conicity as said outside surface and forming part thereof
- said slot extending through said end surface secantlike into the bobbin body between the inside and outside surfaces of the hollow bobbin body and between two circumferentially spaced locations on said outside surface.
