Definitions

  • the invention refers to a tube for the formation of bobbins of yarn, suitable for axial alignment with similar adjacent tubes and for mounting onto suitably equipped textile machines and on traditional dyeing plants, said tube comprising an annular step and an end portion that protrudes from said step and has a smaller diameter than the outer diameter of the tube.
  • Tubes of this kind are known for example from US-A-2 942 801.
  • This known tube has a cylindrical cylindrical skirt with perforated wall and a cylindrical end portion, the outer diameter of which is smaller than the outer diameter of the tube.
  • a plurality of tubes on which bobbins of yarn have been formed by a spinning machine or the like can be superimposed in axial alignment and inserted onto a rod of a dyeing apparatus. The top end portion of each tube is inserted into the bottom portion of the subsequent tube, in such a way that a superimposition of a plurality of tubes is obtained.
  • FR-A-1 416 340 discloses a tube of the above mentioned type, wherein the end portion is frustoconical, whereas the bottom portion of the tube has a corresponding frustoconical recess for receiving the frustoconical end portion of a correspondingly shaped tube.
  • the frustoconical end portion of this known tube has the same functions as the cylindrical end portion of the tube described in US-A-2 942 801.
  • the known tubes are of different types and all of them require different equipment to be provided in the textile machines for the winding and unwinding of the yarn and also in the plants for washing, dyeing and additional operations. This implies significant drawbacks, since the tubes of one type cannot be used with the same equipment designed for a different type of tubes, unless said equipment is changed. These and other drawbacks are known to those skilled in the art, said drawbacks being caused by tubes of different shapes, each of which is, in addition, much spread on the market.
  • the object of the present invention is to provide a tube according to the preamble of claim 1, which can be used on suitably equipped traditional dyeing plants and on textile plants (such as winding frames, open-end spinning machines and other) by using tailstock plates of special type, which are suitable for supporting tubes of known type as well as new tubes according to the invention.
  • the end portion of the tube comprises a first substantially cylindrical portion and a second portion forming a tapering profile, said tapering profile defining a centering hole.
  • the tube according to the invention can be used on winding or spinning frames of known type and at the same time (after the yarn has been wound on the tube to form a bobbin) on dyeing plants provided with rods onto which the tubes are inserted, since the centering hole defined by the tapering or flaring profile guides the tube onto said bar.
  • the only modificaton required on the spinning or winding frame is the substitution of the tailstock commonly used with a plate particularly designed in order to allow for the use (on the same spinning or winding frame) of known tubes and of the tube of the present invention as well.
  • the special plate to be used in combination with the tube according to the invention has a frustoconical edge projection in central position and two opposite annular shaped edges towards the periphery, the edge located on the side of the central projection being able to be received in the zone of the additional tapering profile of the tube when the plate is made to rest against the said tube.
  • the successive axially aligned tubes may be centered one on the other by the step or by the flearing profile.
  • Other tubes e.g. cylindrical tubes, may also be used with the above plate.
  • a tube 1 (Fig.1) of known type is simply provided with a cylindrical skirt having two equal ends with circumferential edge.
  • Fig.2 shows the new type of tube 5 which, in addition to the cylindrical skirt, has an outer step 5A at one end, formed by a cylindrical step-like portion, to form a seat for the lower edge 5X of a tube 5 superimposable therewith; edge 5X corresponds to edges 1X of tube 1.
  • the cylindrical wall of tube 1 and 5 is uniformly perforated.
  • tube 5 has also a flaring profile 5B with two annular, substantially flat portions 5C and 5E, the portion 5C being adjacent to step 5A and portion 5E being adjacent to a hole 5F.
  • Numeral 11 indicates a plate of the special type in question, which is able to engage both tube 5 and the tube 1 of known type indifferently.
  • Plate 11 has a discoidal projection 13 with a frustoconical wall 13A and an annular edge 15 on the same side of projection 13 and with a profile having, at least externally, a flared and mostly frustoconical shape.
  • the plate 11 On the opposite front with respect to projection 13 and annular edge 15, the plate 11 has an annular edge 17 also having, at least externally, a flared and mostly frustoconical profile, and an axial shank 18, for the engagement to the existing plant which utilizes plates like that indicated by 19 of Fig.3.
  • the tube is centered by the projection 13, 13A engaging the profile of edge 5E, 5F, while the profile 5B, 5C allows the fitting of edge 15 into its seat.
  • the edge 15 allows the centering of edge 5X of tube 5 or the centering of an edge 1X of a tube 1, without the need of replacing the plates.
  • a plant may have facing plates which are equal one to the other and of the type indicated by 11, or (as can be seen in Fig.3) a plate 11 and a plate 19 of known type.
  • a mutual centering between adjacent and coaxial tubes 5 can be obtained by means of step 5A which is able to receive the edge 5X.
  • the flaring profile 5B facilitates even a possible automated positioning.
  • the hole 5F allows the centering on shanks or columns of dyeing plants or other.
  • the plate 11 may also be used to make up a tailstock through which the textile plant may be equipped, which plant is thereby capable of utilizing the tubes of the two different types 1 and 5, without any transformation.
