Definitions

  • the invention relates to a thread carrier for winding a filament thread to form a thread reserve, consisting of a cylindrical sleeve with conical edge disks, and a method for forming a thread reserve.
  • a biconical edge spool for a fishing reel with a fixed auxiliary spool, a so-called duplex spool, is known from US Pat. No. 4,076,185.
  • the auxiliary coil is rigidly connected to the main coil. It has a smaller inner diameter than the main coil. It is not intended as a game carrier and is not suitable for quick change on a winder or space-saving transport.
  • Game carriers which consist essentially of a cylindrical rigid tubular body and conical end parts made of plastic, are known as winding sleeves (CH 569 662).
  • Such yarn carriers can also be referred to as biconical bobbins and differ from the symmetrical edge bobbins in that their end faces assume an enlarged diameter towards the periphery.
  • Biconical peripheral coils have proven themselves for winding monofilament medium thickness (about 0 .05 to 0 0.3 mm), but have the disadvantage that the time required for problem-free processing of the monofilament yarn reserve is not provided.
  • the thread reserve is indispensable when automatically changing a thread from an empty to a full bobbin. Without a thread reserve on the conical bobbin, interruptions occur in the weaving mill.
  • the object of the invention is to design a biconical bobbin so that a thread reserve can be taken up.
  • Another task is to design the thread holder in such a way that the thread reserve is not damaged during the transport of the thread.
  • Another task is to make the thread reserve of the full bobbin easy and quick to use.
  • a receiving ring is arranged coaxially displaceably on an extension of the cylindrical sleeve in one of the peripheral disks and protrudes beyond the periphery of the peripheral disk in an extended position.
  • Game carrier and receiving ring are preferably made of a stable plastic. But they can also be made of another durable material.
  • the diameter of the sleeve does not deviate significantly from that of the receiving ring, since the peripheral speed of the thread reserve must be approximately the same as that of the winding at the start of the winding. It is therefore advantageous if both diameters are approximately the same.
  • Recesses between the profiles of the receiving ring have the advantage, on the one hand, that the weight is reduced and, on the other hand, that the thread remnants can easily be removed with scissors.
  • the axially extending profiles give the ring the desired elasticity, which means that it can only be easily inserted into the sleeve and just as easily removed from it.
  • the receiving ring protrudes at least 1 mm above the coil edge in the inserted state, i.e. beyond the periphery of the peripheral disc. This has the advantage that the thread in the region of the sleeve edge is not crushed or otherwise damaged during transport and storage.
  • the periphery can be serrated.
  • a thread of the thread reserve can find a hold in the recesses between the teeth and cannot be damaged between an object and the spool edge during transport or storage.
  • the teeth can be pointed or rounded.
  • the receiving ring can be roughened on its surface and is extended in a first position beyond the edge of the spool. After the thread reserve has been applied, the winding takes place. The receiving ring is pushed into a second position after removal and for transport. To remove the thread reserve twist, the take-up ring is pulled back into the first position and the tension of the running thread is released by a rotary movement.
  • a cylindrical sleeve of a biconical coil is designated by the reference number 1.
  • the sleeve 1 is delimited by a conical edge disk 2 and a conical edge disk 3.
  • the sleeve 1 with the edge discs 2 and 3 is made from one part.
  • a receiving ring 4 is attached inside the cone of the peripheral disk 3. In the extended state, the outer edge of the receiving ring 4 assumes a position A.
  • the inserted receiving ring 4 is drawn in dashed lines.
  • the outer edge of the receiving ring 4 takes the position B here.
  • the sleeve 1 is provided on its inside with at least two parallel ring grooves.
  • An inner annular groove 6 runs in a beach AB to one outer annular groove 5.
  • the receiving ring 4 carries an annular cam 7 on its inside. The position of the annular cam 7 is provided such that it engages in the inner annular groove 5 when the receiving ring 4 is inserted into the sleeve 1.
  • the distance AB is selected so that the axial displacement of the receiving ring 4 when the ring cam 7 engages in the ring groove 5 enables a clean winding with a thread reserve.
  • the receiving ring 4 is provided with profiles 8, which are designed to be elastic, so that the insertion into the sleeve 1 can be done safely and quickly and the ring cam 7 can snap into the groove provided.
  • the slot 9 serves as a thread catch in the direction of the arrow.
  • the yarn carrier with the receiving ring 4 pulled out of the sleeve 1 is placed on the mandrel of a winder, not shown, and accelerated.
  • the thread is guided by a full bobbin so that the thread is gripped by the slot 9 and the rough surface 4 'of the receiving ring of the empty sleeve 1 and the thread reserve is applied to the receiving ring 4 and the thread reserve to the receiving ring 4 is created, which takes about 0.8 to 1.2s.
  • the sleeve 1 is wound.
  • the full spool is removed from the mandrel and the receiving ring 4 is pushed into position B for transport and storage by hand or by machine.
  • winding carriers can be provided on the mandrel of a winder.
  • the winding support according to the invention is particularly suitable for winding high-speed monofilament threads in the titer range from 0.05 to 0.3 mm and has also proven itself at high speeds of stretched threads for automatically changing from an empty bobbin to a full bobbin.
