Definitions

  • ABSTRACT A resiliently compressible bobbin made of a synthetic thermoplastic material which comprises two end rings, a plurality of intermediate rings spaced each other in parallel with and between the end rings, and a number of chair-spaced bent elements, each of which consists of two portions extending parallel to the longitudinal axis of the bobbin and secured to the rings and a portion extending parallel to the plane of the ring, interconnecting any two adjacent rings forming a tubular latticework.
  • the bent elements are arranged regularly and uniformly in a circumferential row and connected longitudinally with each others by said intermediate rings, and bending direction of the bent elements in one circumferential row is opposite to that in adjacent circumferential rows.
  • This invention relates to yarn bobbins employed for dyeing and heat treatment of yarn packages, more particularly, to an improvement in bobbins made of a plastic material which are resiliently compressible along the longitudinal axis thereof.
  • the proposed bobbins are composed of two end ring members and a plurality of flexible, wavy body members connecting these ring members and forming a cylindrical grating, wherein waves in any adjacent wavy body members are parallel to each other and lie in the cylinder surface. After winding yarn upon, the bobbins are compressed lengthwise and charged into a dye bath. However, when yarn is wound on the bobbin as such, the path of the winding yarn often runs substantially parallel with a part of the wavy body member and sometimes coincides therewith.
  • An object of the present invention is to provide an improved resiliently compressible bobbin to overcome various drawbacks of conventional bobbins as described above.
  • Another object of the present invention is to provide bobbins employable for cheese dyeing and heattreatment which are resiliently compressible conforming their own deformation to movements of the innermost yarn in a yarn layer formed thereon and whereby a smooth, homogeneous treatment of synthetic fiber yarn which shrinks during the treatment is performable.
  • a further object of the present invention is to provide a novel compressible bobbin moulded from a synethtic plastic resin material, which permits flow of treating liquid to pass smoothly through its wall and which gives no damage to yarn wound thereon when it is compressed lengthwise.
  • a bobbin moulded from a synthetic thermoplastic material which comprises two end rings, a pluraiity of intermediate rings spaced each other in parallel with and between the end rings, and a number of bendable elements interconnecting any two adjacent rings forming a tubular latticework wherein the bent elements are arranged regularly and uniformly in a circumferential row and connected longitudinally with each others by said intermediate rings, and bending direction of the bendable elements in one circumferential row is opposite to that in adjacent circumferential rows.
  • the two end rings of the bobbin are formed of flanges, one of which is provided with a projection having a slightly smaller outside diameter than the outside diameter of the bobbin tube and the other of which has its inner perephery to fit said projection in, so that when a number of bobbins are superimposed one upon another, the bottom of an upper bobbin can be fit tightly in the top of a lower bobbin.
  • FIG. 1 is a view in side elevation of a bobbin of the invention wherein only the front side is shown for a better understanding and the both upper and lower flanges are partly cut off;
  • FIG. 2 is a plan view corresponding to FIG. 1;
  • FIG. 3 is a side elevational view of the bobbin corresponding to FIG. l in a somewhat axially compressed state wherein a part of the bobbin is omitted;
  • FIG. 4 is a side elevational view similar to FIG. 3 but with the bobbin axially more compressed than with the state of FIG. 3.
  • a plurality of the intermediate rings (2) are disposed at suitable intervals in parallel with and between the both end rings (1) (l').
  • a number of chair-shaped bendable elements (3) extend at suitable intervals.
  • the thus-formed bobbin of tubular latticework comprising the rings (1) (1) (2) and the chair-shaped bendable elements (3) has a number of voids or holes which act as passage holes for the dye liquid or vapour in a dyeing or heat treatment.
  • the shape of the bobbin of the invention may be either cylindrical as shown in FIG. 1 or frustoconical.
  • All the rings (1) (l') (2) and bendable elements (3) are flexible in nature and are moulded as one integral body by means of conventional means e.g., injection moulding from a thermoplastic material such as nylon, polypropylene and the like.
  • the chair-shaped bendable elements (3) consists of two portions (3) (3') extending parallel to the longitudinal axis of the bobbin and secured to the rings (2) (axially parallel portions) and a portion (3") extending parallel to the plane of the ring (2) (parallel-to-ring portion) which inter-connects each two axially parailel portions (3') (3').
  • Longitudinally contiguous chair-shaped bendable elements (3) are bendible alternately in opposite directions as shown in FIG. 3.
  • any adjacent axially parallel portions (3') of adjacent bendable elements are contiguously connected in linear relationship to an intermediate ring (2) therebetween and any adjacent parallel-toring portions (3") extend parallel to each other and thus each bendable element constitutes, as a whole, a contiguous bending connection rib extending between the both end rings (1) (1').
  • the bending connection rib of the bobbin of the invention has portions only parallel and perpendicular to the axis of the bobbin, and none of its portions otherwise inclined to the axis.
  • the total length of two axially parallel portions (3) in each bendable element (3) be substantially equal to the distance between two rings bounding the bent element and be twice or slightly larger than twice the length of the parallel-to-ring portion (3").
  • the thickness of element (3) in a radial direction is equal to that of the ring (2) and is usually greater than the width in a circumferential direction of the element (3).
  • the degree of compression of the bobbin by varying optionally thelength of the parallel-to-ring portion (3"). For instance, in case the length of the parallel-to-ring portion (3") is a half or less than that of the combined length of the axially parallel portions (3, 3') it is possible to compress axially the bobbin up to half or less of the original length.
  • both terminal end rings l) (l are formed of flanges which are so devised as to stabilize superimposing of bobbins.
  • One flange (the lower end one in FIG. 1) is provided with a projection having a slightly smaller outside diameter than the outside diameter of the bobbin and the other flange (the upper end one in H6. 1) has an inside diameter (4) which is recessed to conform to and receive therein the outside diameter of the projection (5).
  • the bottom of a bobbin to be superimposed is fitted in the top of the adjacent bobbin, and the top of the former fits similarly in another adjacent bobbin, and so on to form an as sembly oi axially connected bobbins.
  • the embodiment as described above is desirable, but such flanges may not always be formed.
  • FIG. l, FIG. 3 and FIG. 4 Each compressed state of the resiliently compressible bobbin of the present invention is shown in FIG. l, FIG. 3 and FIG. 4, wherein at first the bobbin in FIG. l is in a state under no compression; in a somewhat compressed state in FIG. 3, wherein the parallel-to-ring portion 3") is inclined and the axial length of the bobbin is shortened by the compression while holding the initial diameter of the bobbin; and in a further compressed state in FIG. 4 wherein the axial length of the bobbin is further shortened by bending and at last the both terminals of the parallel-to-ring portion (3") become close together to the rings at the both sides.
  • the terminals of the parallel-to-ring portions (3") engage with the rings (2) at predetermined contact points and there are formed triangleor square-shaped voids or holes for flowing and passing dye liquid therethrough between each pair of rings (refer to FIG. 4).
  • the bobbins are first wound up with yarns in a suitable yarn layer density, subsequently compressed by pressing together from the both ends thereof, thereby making the yarn layer density homogeneous, and thereafter placed in a dyeing machine or heat-treatment machine to accomplish the treatment in which the bobbins are superimposed one another by tight fitting the lower projections in the top end of lower bobbin.
  • the yarn package in a homogeneous density may be treated with dye liquid or vapour being well flown and passing through the triangleor square-shaped holes in the peripheral wall of the bobbin, and no unevenness of treatment is brought about since shrinkage of yarns is absorbed by their slackening caused by compression of the bobbin.
  • the unwinding resistance of the yarn wound around the bobbin can be greatly decreased owing to simultaneous compression of the bobbin and yarns layers.
  • A. resiliently compressible bobbin made of a synthetic thermoplastic material comprising: two end rings, a plurality of intermediate rings positioned between said end rings in spaced-apart parallel relationship with respect to each other and with respect to said end rings, and a plurality of bendable elements positioned between each two adjacent rings each consisting of two linear terminal portions extending parallel to the longitudinal axis of the bobbin and secured to the rings and one linear intermediate portion extending perpendicular to said terminal portions and interconnecting said two terminal portions thereby interconnecting each two adjacent rings and forming a hollow latticework, and wherein the bendable elements positioned between each two adjacent rings are arranged regularly and uniformly in a circumferential row and wherein each adjacent terminal portion of the bendable elements in adjacent circumferential rows lie in a straight, connected line with each other to enable bending of the bendable elements in one circumferential row in a bending direction opposite to that of the bendable elements in adjacent circumferential rows in response to compressive forces axially applied to said bobbin.
  • a resiliently compressible bobbin composed of resiliently deformable material comprising: a plurality of rings positioned in mutually spaced-apart parallel relationship; and a series of resiliently deformable elements positioned in circumferentially spaced-apart relationship between and connected to each two adjacent rings collectively defining therewith a hollow latticework, each resiliently deformable element having a pair of elongated end portions each connected at one end to different ones of adjacent rings at circumferentially spaced-apart and longitudinally offset locations therealong with respect to each other and having means interconnecting the other ends of said elongated end portions for resiliently deforming into engagement with said adjacent rings at predetermined contact points thereon during axial compression of the bobbin to limit the extent of axial compression of the bobbin.
  • each elongated end portion extends in a linear direction, and wherein said means interconnecting the other ends of each said pair of elongated end portions comprises an intermediate linear portion extending transversely with respect to each said pair of end portions.
  • a resiliently compressible bobbin according to claim 8 wherein all said elongated end portions extend parallel to the longitudinal axis of the bobbin and all said intermediate linear portions extend perpendicular to said longitudinal axis.
