Definitions

  • cop carrier a sleeve upon which all single and multiple threads covered by the term yarn may be wound, the processing of which is eifected on spinning, spooling or twisting machines.
  • the sleeves employed in connection with such machines have heretofore been designed as a single coherent part in order to impart upon the sleeve a suflicient stability during the winding of the yarn upon said sleeve as well as during the transport of the sleeve within the plant and also out of the plant.
  • the heretofore known two-sectional yarn sleeves have the drawback that their stability is insuflicient in view of the relatively short overlapping length of the sections, and this lack of stability is encountered not only during the winding up of the yarn on the respective processing machine but also during the further processing, particularly during the transport, because such two-sectional-yarn sleeve has the tendency to bend.
  • This naturally affects the cop so that considerable difiiculties can be encountered when processing the cop at the bent portion. In particular, breaks in the thread are caused thereby and even a number of layers may be pulled off at the same time which then constitute waste.
  • FIG. -1 is a longitudinal section through a cop carrier according to the invention, which consists of a main bobbin body and an auxiliary bobbin body.
  • FIG. 2 illustrates the same cop carrier as FIG. 1 but in a different position of the auxiliary bobbin body.
  • FIG. 3 is a longitudinal section through a cop carrier according to the present invention, in which the main bobbin body is composed of an inner bobbin body and an outer transport bobbin body mounted on said inner bobbin body.
  • PEG. 4 is a longitudinal section through a cop carrier according to the invention, in which the main bobbin body is provided with two auxiliary bobbin bodies, said carrier being shown in its position for the first phase of receiving the yarn.
  • FIG. 5 shows the same cop carrier as 'FIG. 4 in a position for the second phase of receiving the yarn.
  • FIG. 6 illustrates the same bobbin carrier as FIGS. 4 and 5 in a position for the third phase of receiving the yarn.
  • FIGS. 7a, 7b and 70 respectively illustrate in cross section different cross sectional shapes of a cop carrier according to the present invention.
  • FIGS. 8 and 9 respectively illustrate in longitudinal section the lower end of a cop carrier according to the present invention.
  • the cop carrier according to the present invention is characterized primarily by a hollow main bobbin body having a substantially uniform cross section throughout its length, and having displaceably mounted thereon one or more auxiliary bobbin bodies, the length of said auxiliary bobbin bodies or bobbin body equalling substantially the length of the main bobbin body divided by the quotient of the number of all auxiliary bobbin bodies plus one and the number of the auxiliary bobbin bodies plus one superimposed upon the respective auxiliary bobbin body.
  • the invention permits the manufacture of a cop carrier for large cops, which consists at least of two parts permanently superimposed upon each other and which due to this superimposed condition over the total length of each auxiliary bobbin body will have a stability at least equalling that of a yarn sleeve consisting of a single part.
  • the cop carrier according to the present invention may even have a higher stability.
  • a cop carrier according to the present invention also improves the conditions in spinning technological respect while simultaneously facilitating the handling and servicing of the cop carrier.
  • the main bobbin body and the auxiliary bobbin bodies may have identical wall thickness.
  • the main bobbin body may have a greater wall thickness than the auxiliary bobbin body or bobbin bodies.
  • the main bobbin body may be composed of an inner supporting bobbin body and a superimposed transport bobbin body of approximately the same length, in which instance the latter may have the wall thickness of an auxiliary bobbin body.
  • the main bobbin body and the auxiliary bobbin body or bobbin bodies have a cross sectional shape, for instance oval or polygonal, which is identical with regard to the respective diameter and which will bring about the transmission of rotation from one bobbin to the other.
  • a cross sectional shape for instance oval or polygonal
  • a further feature of the present invention is seen in that the main bobbin body and the auxiliary bobbin body or bobbin bodies are adapted to be connected to each other in a predetermined relative position as to height.
  • This last mentioned feature is not indispensable in any case because, if desired, the cross sectional shape of the main bobbin body and of the auxiliary bobbin body or bobbin bodies will in addition to securing the radial position also assure the axial position to a sufficient extent.
  • the cop carrier illustrated therein comprises a hollow main bobbin body 1 of substantially uniform cross section throughout the length thereof.
  • auxiliary bobbin body 2 Placed upon the main bobbin body 1 is an auxiliary bobbin body 2 which permanently remains on the main bobbin body 1 but is axially displaceable thereon.
  • auxiliary bobbin bodies may together with the same or common main bobbin body form a cop carrier as will be explained further below.
  • the length of the main bobbin body 1 determines the length of the cop, whereas the length of the auxiliary bobbin body or bobbin bodies 2 is at a certain ratio with regard to the length of the main bobbin body 1.
  • This ratio is, according to the present invention, so selected that the length of the auxiliary bobbin body substantially equals the length of the main bobbin body divided by the quotient the enumerator of which equals the number of all auxiliary bobbin bodies+l while the denominator equals the number of all auxiliary bobbin bodies-H which are superimposed upon the respective auxiliary bobbin body whose length is to be ascertained.
  • the length of the auxiliary bobbin body will be approximately half the length of the main bobbin body.
  • the length of the inner auxiliary bobbin body mounted on the main bobbin body will be approximately /a of the length of the main bobbin body, whereas the second auxiliary bobbin body mounted on the first auxiliary bobbin body will have a length equalling /3 of the main bobbin body.
  • the cop carrier composed of the main bobbin body and three auxiliary bobbin bodies mounted thereon, the
  • auxiliary bobbin bodies in the sequence from the innermost to the outermost auxiliary bobbin body will respectively amount to A, /2 and A of the length of the main bobbin body.
  • the main bobbin body and also the auxiliary bobbin bodies may consist of various materials, for instance the main bobbin body may be wound up of paper in the same manner as it is generally known in connection with paper sleeves or mailing tubes.
  • the thus obtained bobbin bodies may also be impregnated.
  • the cop carriers may also be made of synthetic material or metal while, depending on the purpose of employment, the main and auxiliary bobbin bodies may be made of the same or different materials.
  • the main bobbin body and the auxiliary bobbin bodies may have the same wall thickness. In the embodi ment illustrated in FIGS. 1 and 2, the main bobbin body 1 which is assumed to have been made up of wound paper, has a greater wall thickness than the auxiliary bobbin body 2.
  • a cop carrier according to the present invention as so-called transport sleeve as shown for instance in FIG. 3.
  • the main bobbin body is, in contrast to FIGS. 1 and 2, composed of two sections of substantially identical length. More specifically, the cop carrier according to FIG. 3 consists of an inner carrier body 3 and a superimposed transport body 4 of substantially the same length as carrier body 3. Furthermore, an auxiliary bobbin body 5 is mounted on the transport body 4. The wall thickness of the transport body 4 substantially corresponds to the wall thickness of the auxiliary bobbin body 5.
  • FIGS. 4, 5 and 6 illustrate a cop carrier according to the invention which is composed of a main bobbin body 6 and two superimposed auxiliary bobbin bodies 7 and 8.
  • FIGS. 4 to 6 respectively illustrate diiferent positions of the auxiliary bobbin bodies 7 and 8 on the main bobbin body 6 during the winding up operation of the yarn upon the cop carrier.
  • the relative positions of the bobbin bodies according to FIG. 4 correspond to the first winding phase
  • the relative positions of the bobbin bodies according to FIG. 5 correspond to the second winding phase
  • the relative positions of the bobbin bodies according to FIG. 6 correspond to the third phase of the winding operation.
  • FIGS. 7 a, 7b and 7 c respectively illustrate various possibilities with regard to the design of the cross section of the bobbin body. As will be seen from these figures, the
  • main bobbin body and the auxiliary bobbin body or bodies have a cross sectional shape in conformity with the diameter thereof, the cross sectional shape being such as to cause the auxiliary bobbin bodies to rotate together with the main bobbin body.
  • the main bobbin body 9 and the auxiliary bobbin body 10 have a corresponding non-round contour so that the main bobbin body 9 and the auxiliary bobbin body 10 are prevented from rotating relative to each other, i.e. when the main bobbin body 9 is rotated, also the auxiliary bobbin body 10 will be rotated without any slip loss.
  • the main bobbin body 11 is provided with longitudinal grooves 13 engaged by corresponding longitudinal beads 13' of the adjacent auxiliary bobbin body.
  • Corresponding beads are provided on the other auxiliary bobbin bodies for engagement with corresponding grooves in the respective bobbin bodies therebelow. In this way, also a proper slip-free rotation of the auxiliary bobbin bodies with the main bobbin body will be assured.
  • the main bobbin body 14 and the auxiliary bobbin body 15 are designed as corresponding polygons so that also in this instance a slip-free rotation of the auxiliary bobbin body with the main bobbin body will be assured.
  • the arrangement also creates a tolerance compensation for the manufacturing tolerance of the bobbin bodies.
  • the various cross sectional shapes of the bobbin bodies assure the uppermost winding of a winding layer so that the various layers of the wound up yarn of the cop will rest slip-free on the cop carrier.
  • FIG. 8 illustrates by way of example how the main bobbin body 16 and the auxiliary bobbin body 17 are adapted to be coupled together at a predetermined height.
  • the lower end of the main bobbin body 16 is provided with annular grooves having resting therein a ring 18 which may be engaged by a corresponding groove in the auxiliary bobbin body 17. In this way, the relative position as to height between the main bobbin body 16 and the auxiliary bobbin body 17 will be assured.
  • the lower end of the mainbobbin body 19 is provided with reinforcing head 20 so that the-lower end of the auxiliary bobbin body 21 can be seated upon the shoulder formed by said reinforcing head 20. It is, of course, to be understood that various other possibilities exist in order to establish a definite relative location of one or more auxiliary bobbin bodies with regard to the main bobbin body.
  • the winding of a yarn upon a cop carrier according to the present invention is effected in the following manner.
  • this carrier is first placed upon a spindle adapted to rotate, and the auxiliary bobbin body 2 is moved into FIG. 1 position which means that the auxiliary bobbin body 2 during the first winding phase occupies its upper position at the upper portion of the main bobbin body 1.
  • the rings are with their runners brought into such a position that the first winding layer will start at the lower end of the auxiliary bobbin body 2. The winding operation will then be continued in customary manner until nearly the upper end of the auxiliary bobbin body 2 has been reached.
  • the winding up operation will then be continued under these conditions until the upper end of the main bobbin body 1 has been covered with yarn in the customary manner. Also during this second phase, the winding is effected with a similarly favorable balloon length as was the case during the first winding phase. As soon as the yarn body on the cop carrier has been completed, the cop carrier together with the cop thereon is withdrawn from the spindle and may now be processed further. It will be obvious that the main bobbin body 1 together with the auxiliary bobbin body 2 forms a stable cop carrier which has no tendency to bend during the operation or during further processing.
  • the winding up operation will be effected in the same manner as described above. After the winding operation has been completed, in this instance only the transport body 4 with the auxiliary bobbin body 5 thereon and the cop on the bobbin bodies 4 and 5 will be withdrawn from the main bobbin body 3 and passed on for further processing.
  • the winding up of yarn upon a cop carrier composed of a main bobbin body and two auxiliary bobbin bodies as illustrated in FIGS. 4 to 6 is efiected in a similar manner.
  • the upper ends of the 'main bobbin body 6 and also of the two auxiliary bobbin bodies" 7 and 8 are approximately at the same level, and the winding up of the yarn upon the entire cop carrier starts at the lower end body 8.
  • the auxiliary bobbin body 8 As soon as the wound up yarn has reached the. upper end of the auxiliary bobbin body 8, the latter is displaced into FIG; 5 position, and the winding up operation is continued while the yarn passes from the auxiliary bobbin body 8 to the auxiliary bobbin body 7.
  • a cop carrier according to the invention may in various manners be adapted tothe various purposes of employment without sacrificing the essence of the present inventron. With many machines a continuous winding up of a yarn on a cop carrier according to the invention is possible when the parts controlling the winding permit corresponding movements.
  • a cop carrier which comprises in combination: a mam tubular bobbin member equalling in length at least the total length of the maximum cop to be produced on said cop carrier, and at least one auxiliary tubular bobbin means surrounding and slidably engaging said main tubular bobbin member, said auxiliary bobbin means being considerably shorter than said main bobbin member and being adjustable in longitudinal direction thereof relative to and between the ends of said main bobbin member into diiferent positions for winding yarn on said cop carrier, said auxiliary bobbin means being supported in any of the auxiliary bobbin of said positions along its entire length by said main bobbin member.
  • a cop carrier which comprises in combination: a main tubular bobbin member equalling in length at least the total length of the maximum cop to be produced on said cop carrier; at least one auxiliary tubular bobbin means having a substantially uniform inner diameter along its length and surrounding and slidably engaging said main tubular bobbin member; said auxiliary bobbin means being adjustable in longitudinal direction thereof relative to and between the ends of said main bobbin member into different positions for winding yarn on said cop carrier, said auxiliary bobbin means being supported in any of said positions along its entire length by said main bobbin member; the respective length of each auxiliary bobbin means equalling the length of said main bobbin member divided by the quotient having as enumerator the total number of all auxiliary bobbin means around said main bobbin member, increased by one, and having as denominator that number of auxiliary bobbin means which have an inner diameter larger than the outer diameter of the respective auxiliary bobbin means the length of which is to be determined, increased by one.
  • a cop carrier according to claim 2 in which the main bobbin member and the auxiliary bobbin means have the same wall thickness.
  • a cop carrier according to claim 2 in which the main bobbin member and the auxiliary bobbin means have different wall thicknesses.
  • a cop carrier which comprises in combination: a main tubular bobbin member equalling in length at least the total length of the maximum cop to be produced on said cop carrier, said main tubular bobbin member comprising an inner tubular supporting body and a tubular transport body disengageably mounted on said supporting body and having a length substantially equalling the length of said supporting body, and at least one auxiliary tubular bobbin means surrounding and slidably engaging said main tubular bobbin member; said auxiliary bobbin means being considerably shorter than said main bobbin member and being adjustable in longitudinal direction thereof relative to and between the ends of said main bobbin member into difierent positions for winding yarn on said cop carrier, said auxiliary bobbinmeans being supported in any of said positions along its entire length by said main bobbin member, the wall thickness ofsaid transport body and the wall thickness of said auxiliary bobbin means being approximately the same.
  • a cop carrier according to claim 1 in which said main bobbin member and said auxiliary bobbin means surrounding said main bobbin member are provided with meansfor rotatably inter-engaging same.
