Definitions

  • the nose of the pirn is formed or provided with a tension controlling or balloon controlling device comprising a neck of circular cross section formed or provided with flanged or enlarged ends or shoulders and having a light ring floating thereon between the flanges, ends or shoulders.
  • the neck may if desired be formed in one with or be an integral part of the pirn, but we prefer to fit a neck of brass or other suitable metal on to the nose of the pirn.
  • Figure 1 is a view of the pirn, supposed as in the shuttle (not shown) in the operation of weaving and as travelling in the direction of the arrow.
  • Figure 2 is a section of the tension controlling device on the nose of the pirn.
  • the nose of the pirn l is fitted with a cylindrical neck 2 formed with shoulders or flanges 3 and 4, and having a light ring 5 of circular cross-section floating loose thereon between the shoulders or flanges.
  • the neck 2 and the floating ring 5 are made of brass, steel or other suitable metal.
  • the neck 2 is formed in two parts, an upper part 6 and a lower part '7 adapted to be screwed together in the manner shown. This construction facilitates the mounting of the floating ring 5 on the neck 2 and readily enables the ring 5 to be changed for a ring of different size or weight.
  • the neck 2 is mounted on to the nose of the 5 pirn by means of the screw 8 formed with the lower part 7 of the neck 2.
  • the neck 2 may have any other shape of circular cross section, for instance, the neck may be concave or inwardly curved, the ends of 7 the curve forming shoulders.
  • the next point of support e. g. an eye in the 7 shuttle.
  • the tension of the yarn may be varied according to the weight of the ring 5 and the clearance between the ring 5 and the neck 2, and according to the chamfering of the shoulders or flanges 3 and 4. 5
  • the pirn of the invention is of great use in weaving with looms provided with automatic pirn changing devices, as the tension conditions can be arranged or provided for beforehand on the pirn in the magazine of the loom and similar tension conditions can be arranged or provided for on a number of such pirns in the magazine of the loom.
  • the yarn When weaving with looms employing automatic pirn changing devices the yarn may be threaded under the ring 5 previous to filling up the magazine and similar conditions of tension may be provided for on a number of such pirns before they leave the magazine.
  • the pirn of the invention may be employed in self threading types of shuttle.
  • a pirn for use in loom shuttles provided with a tension-controlling device comprising a neck of circular cross-section forming a continuation of the small end of the pirn tube, and provided with no enlarged ends, and a ring of circular cross-section freely mounted on said neck between said enlargements and adapted when the pirn is working in a shuttle to move horizontally under the frictional action of the yarn passing through it, and to nip the yarn against the enlarged portion of the neck, so as to impart a controlled tension to the yarn leaving the pirn.
  • a pirn for use in loom shuttles provided with a tension-controlling device comprising a neck of circular cross-section forming a continuation of the small end of the pirn tube, said neck curving inwardly from its ends, and a light ring of circular cross-section freely mounted on said neck and adapted when the pirn is working in ashut: tle to move horizontally under the frictional action of the yarn passing through it, and to nip the yarn against the enlarged portion of the neck, so as to impart a controlled tension to the yarn leaving the pirn.
  • a pirn for use in loom shuttles provided with a tension-controlling device comprising a neck of circular cross-section forming a continuation of the small end of the pirn tube, said neck being constituted by two parts secured together and curving inwardly to the point of connection, and a light ring of circular cross-section freely mounted on said neck and adapted when the pirn is working in a shuttle to move horizontally under the frictional action of the yarn passing through it, and to nip the yarn against the enlarged portion of the neck, so as to impart a controlled tension to the yarn leaving the pirn.
