Definitions

  • the invention relates to a godet with a circumferential speed of at least 2500 m / min, to which a running thread is applied, and a separating roller, as well as a method for applying a running thread to the godet and the use of the godet.
  • US-A-3-020-621 relates to a driven godet with a matt and a polished part, the middle part being polished and the two edge parts being matt, and a polished separating roller.
  • the driven godet must have zones of different roughness; under special conditions, the separating roller can also have such zones when it is driven.
  • Such a device has disadvantages when fine fibrillated threads are to be placed at high speeds. Due to the low frictional connection, there remains a speed difference between the thread and the separating roller, which cannot be kept constant over a long period of time.
  • the known device has the further disadvantage that only the highly polished part of the godet can be used for operation during operation and thus only a limited number of turns can be provided.
  • the method has apparently given satisfactory results at low thread speeds below 1000 m / min, but is unsuitable for applying a thread with a high initial speed on a rapidly rotating godet.
  • DE-AS 16 60 149 also relates to a device for drawing and heat treating a thread made of thermoplastic polymers with a driven drawing roller, a thread separating roller and a fixed roller.
  • the separating roller is matt chrome-plated over its entire surface, which is sufficient for the transfer of low speeds to a running thread.
  • the thread has no constant properties. The relative movement between the thread and the peripheral speed of the separating roller naturally results in greater wear on the surface of the separating roller.
  • the object of the present invention is a running thread at high speed to put on a driven high-speed godet with separation roller.
  • the present object is achieved according to the invention in that the surface of the separating roller has two zones of different roughness.
  • each zone extends to approximately half of the separation roller.
  • the location of the zone with the larger and smaller roughness is determined by the area of application. If the thread tension of the running thread is greater at the inlet than at the outlet, it is advantageous if the zone with the smaller roughness at the inlet is on the motor side, because then it is better guaranteed that the thread and the reel have the same speed.
  • the area with the coarser roughness is at the front.
  • the position at the rear and front is determined by the position of the motor for driving the godet: rear means where the motor is attached. If the tension of the thread at the outlet is greater than at the inlet, the zone with the greater roughness is located at the back.
  • the zone with the greater roughness is matt chrome-plated or ceramic-coated.
  • a matt chrome-plated zone means a zone that is first sandblasted and then chrome-plated, creating a so-called orange peel surface.
  • a surface which is also suitable can also be provided by means of ceramic coating and special treatment, i.e. by means of brush grinding.
  • Suitable terms for describing and defining surface roughness exist in German and American standards. The most important term is the ⁇ mean roughness ⁇ according to DIN ( ⁇ Roughness Height ⁇ ASA B 46.1-1962), which is the arithmetic mean of the distances of the actual profile from the middle profile, measured perpendicular to the middle profile.
  • the mean roughness (1) of the surface with the greater roughness is between 0.5 and 2.2 micrometers (»m), preferably between 0.6 and 2.2» m.
  • polished surfaces have an average roughness value of 0.04 »m.
  • the rough surface of the separation roller also has the following roughness values: (2) Roughness 4.5 - 8.0 »m (3) Medium roughness 1.6 - 3.0 »m (4) Height distance Max. 140 »m (5) Average height distance 40 - 60 »m (6) Profile curvature Max. 0.030 »m ⁇ 1
  • the invention further relates to a method for applying a running thread to the device described above, characterized in that the thread in contact with the matt part of the by means of a thread guide Separating roller is brought and after removal of this thread guide runs on the polished part of the separating roller.
  • the device according to the invention can be used wherever a godet is used which has to be wrapped around at least 360 °.
  • the thread separation roller then has the effect that the running and running thread lie separately from one another on the roller.
  • the invention further relates to the use of the above-mentioned device in a quick spin, spin draw, quick spin draw, stretch, texturing, stretch texturing, spin stretch texturing or heat treatment process.
  • This spin-stretching system consists of a driven delivery godet 1 with its corresponding separating roller 2 and a driven take-off godet 3 with its corresponding separating roller 4.
  • the separating roller 4 has a chrome-plated part a at its free end and a chrome-plated part b on the motor side.
  • a thread 5 comes from a spinneret and is placed five times on the delivery godet 1 by means of a thread take-up device. For further retraction, the thread 5 is placed over a thread guide 6 on the take-off godet 3 and on the matt chrome-plated part a of the separation roller 4 with at least 2-3 turns. The thread guide 6 is then removed from the thread path, with the result that the thread turns on the take-off godet 3 shift rearward onto the bright chrome-plated part b. Thereafter, further wraps can be placed around the take-off godet 3, and the thread 5 can be passed on to the next pair of rollers or to a winder or to a texturing zone.
  • the high speed of the thread means a speed of at least 2500 m / min.
