Definitions

  • the invention relates to an endless yarn traversing belt for a yarn traversing device on a machine that produces bobbins, which is provided at intervals with yarn carriers which are arranged on the narrow side of the yarn traversing belt and have the shape of a saw tooth, as known from GB-A 1 024 639, and methods for its manufacture.
  • the invention has for its object to improve a generic yarn traversing belt so that it is particularly well suited for yarn traversing, can be easily manufactured, is subject to low wear and can be operated with a simple, inexpensive drive device.
  • this object is achieved in that the yarn traversing belt consists of fabric embedded in rubber-elastic material made of textile and / or metal threads and that the front flanks of the yarn drivers have a sleeve-like reinforcement made of wear-resistant material.
  • a new and inventive method for producing a yarn traversing belt described in the preamble of claim 1 is characterized in that a fabric is made from textile and / or metal threads, the fabric, optionally multi-layered, embedded in rubber-elastic material and from a band-shaped strip of the structure thus obtained Parts are punched out so that the gamma carriers stop, and then the front flanks of the yarn carriers are provided with sleeve-like reinforcements.
  • An alternative method for producing an endless yarn traversing belt according to the preamble of claim 1 is characterized in that a fabric is made from textile and / or metal threads, several layers of the fabric are placed on top of one another and flexible yarn carriers are inserted in between, and the whole is then embedded in rubber-elastic material and then the front flanks of the yarn carriers are provided with sleeve-like reinforcements.
  • the yarn traversing belt is bought at both ends and that the two ends are then overlapped, glued, welded or vulcanized to one another.
  • the multilayer of the tissue carcass is brought about by winding the tissue over a core.
  • the relatively steep front flank of the yarn drivers which is inclined from the vertical from the vertical at a maximum of about 10 degrees, ensures good yarn entrainment when traversing and at the same time does not hinder the delivery of the yarn at the reversal points of the traversing.
  • a convex or convex broken course of the back flank of the gamma taker ensures the required stability and prevents the yarn from getting caught on the back of the yarn taker.
  • the rounding of the transitions between the yarn traversing belt and the yarn drivers ensures long durability and prevents fatigue breaks by virtually eliminating the occurrence of a notch effect.
  • a sleeve-like reinforcement of the front flank of the yarn driver is particularly simple, economical and durable.
  • Such a design of the reinforcement also does not appreciably impair the flexibility of the yarn traversing belt, particularly if the reinforcement consists of a resilient sleeve having a longitudinal slot, which is connected to the yarn driver in a force-locking manner by its spring force, spanning the front flank. Then there is only a line contact with the yarn driver.
  • Such sleeves are already in use in other fields of technology as so-called adapter sleeves or tension pins, so that these standard parts can be used here with advantage.
  • the yarn traversing belt When manufacturing the yarn traversing belt, one can start from a plate-shaped or from a belt-shaped carcass. Fully vulcanized plates can first be cut into strips, for example, and then the yarn carriers can be produced by punching out. Band-shaped carcasses can be produced, for example, by winding them up, so that subsequent roughening and gluing, welding or vulcanizing is not necessary. However, embedding the carcass in rubber-elastic material is only possible with special devices. So both branches of production have their advantages and disadvantages.
  • the yarn traversing device of a machine producing cross-wound bobbins is designated as a whole by (1).
  • the yarn (2) is fed with the help of the yarn traversing device (1) in the direction of the arrow (3) to a rotating cheese (4) and wound up there in layers.
  • the yarn traversing device (1) constantly traverses the yarn (2) in the direction of the double arrow (5).
  • An endless yarn traversing belt (6) is used for traversing.
  • the yarn traversing belt (6) wraps around the rollers (7 to 12), of which the roller (8) has a drive motor (13). All six rollers are mounted on a support body (15).
  • the support body (15) also carries a yarn guide plate (14).
  • the yarn guide plate (14) has a yarn guide contour (16) which increases towards the ends of the traversing area, as shown in FIG. 2.
  • the yarn traversing belt (6) is provided with three yarn carriers (17, 18, 19) at intervals. All three yarn drivers are arranged on the narrow side of the yarn traversing belt and have the shape of a sawtooth.
  • the front flanks of the yarn carriers (17 to 19) point in the running direction (20) of the yarn traversing belt (6) and are each provided with a sleeve-like reinforcement (21) made of wear-resistant material.
  • the yarn driver (17) moves straight to the left. He takes the yarn (2) with it, which slides along the yarn guide contour (16) of the yarn guide plate (14) until the yarn driver (17) dips behind the rising yarn guide contour (16) and releases the yarn (2), which is then released by the yarn driver (18) traveling from left to right and then traversed from left to right until the yarn is then captured by the third driver (19), which then traverses it again from right to left and so on.
  • the yarn traversing belt (6) consists of fabric made of textile threads embedded in rubber-elastic material. Alternatively, metal threads can also be woven into this textile fabric, preferably in the direction of tape travel.
  • Fig. 2 shows that the steep flank of the yarn carriers (17 and 18) is arranged perpendicular to the yarn traversing belt (6). The same applies to the thread driver (19).
  • the back flank (22, 22') of the yarn driver (18 ') has a convex broken course.
  • the back flank (22) extends from the end (23 ') of the front flank (23) at an angle Beta of approximately 10 degrees towards the yarn traversing belt (6'). After changing direction, the back flank (22) then slopes more.
  • the reinforcement (24) consists of a resilient sleeve which has a longitudinal slot and, by means of its spring force, is non-positively connected to the yarn driver (18 ') across the front flank (23).
  • This sleeve (24) is made of rustproof steel.
  • 3 and 4 is arranged perpendicular to the yarn traversing belt (6 '), the front flank (23') of the yarn driver (armored by a sleeve (24 ') is located 18 ") of the yarn traversing belt (6") in the embodiment according to FIG. 5 inclined at an angle alpha of approximately 10 degrees from the vertical against the direction of the belt running.
  • the back flank (22 ') of the gamma driver (18 ") has a convex shape.
