Definitions

  • the invention relates to a funnel for a funnel spinning device with an axially aligned inlet channel and with an adjoining connecting channel leading to the outside and opening into a funnel jacket.
  • the connecting channel opens into a region of the funnel shell which is kept relatively short in the axial direction and which has a frustoconical shape with a relatively strong inclination. This area is then adjoined by a cylindrical section which merges into a section which widens in the shape of a truncated cone.
  • the invention has for its object to design a funnel for a funnel spinning device so that the thread run is improved and the lifting of the thread from the funnel jacket is reliably avoided even at high speeds and the associated centrifugal forces.
  • the object is achieved in that the region of the funnel jacket facing away from the inlet side adjoins the mouth of the connecting channel with a continuous course, this region extending at least over half the axial length of the funnel jacket. This ensures that the thread, after it has emerged from the mouth and is on the funnel jacket, does not have to be deflected again in order to keep it on the outer surface of the funnel jacket. By avoiding another deflection point reduces the risk that the thread will lift off the funnel jacket and form a balloon, which can have an adverse effect on the spinning process, since this affects the thread quality and also the energy consumption.
  • the area of the funnel shell following the mouth of the connecting channel has an inclination of less than 5 ° to the axial.
  • the funnel casing starting from the mouth of the connecting channel, the funnel casing initially has a cylindrical section which is adjoined by a section which is widened in the shape of a truncated cone.
  • the shape of the funnel is adapted relatively closely to the shape of the cop to be spun, so that the diameter of the funnel and thus also its mass and air resistance can be kept relatively small.
  • the funnel jacket is widened in the shape of a truncated cone starting from the mouth of the connecting channel.
  • a funnel can also be adapted very closely to the shape of the cop, with the advantage of simpler manufacture being obtained here.
  • the funnel jacket has a continuously cylindrical outer surface in the region adjoining the mouth of the connecting channel.
  • the funnel has the largest mass and is therefore somewhat less favorable than the other designs in terms of energy consumption.
  • the production is easier because the funnel can be made from a piece of pipe.
  • this funnel shape has the advantage that it is possible to produce a cop which consists of parallel windings instead of the conventional cop construction.
  • the funnels (8, 9, 10) shown in FIGS. 1 to 4 are intended for a so-called funnel spinning machine, in which the funnel is arranged between a drafting system and a rotating spindle. In the event of twisting, the drafting system is replaced by another delivery device.
  • the funnels (8, 9, 10) have in their inlet area a cylindrical pin (7) with which they are freely rotatable.
  • the pin contains an axially aligned inlet channel (11), to which a connecting channel (12) adjoins at an angle of approximately 120 °, which opens on the outside with an opening (14) in the funnel jacket (13a, 13b, 13c).
  • the cylindrical section (15) extends over half the axial length of the funnel jacket (13a) and up to about 2/3 of this length.
  • the thread runs helically on the funnel jacket (13a) and is wound into a cop (20) on a bobbin tube (21), which is attached to a spindle, not shown.
  • the thread running helically over the funnel jacket (13a) takes the funnel (8) with it.
  • the funnel (8) assumes a speed which is dependent on the respective winding diameter, ie the funnel (8) is continuously accelerated and decelerated again. This also applies in the same way to the embodiments according to FIGS. 2 and 3 when a cop (20) is wound in the usual construction.
  • the mouth (14) of the connecting channel (12) opens at a distance from the end of the lateral surface (13a, 13b, 13c) facing the inlet side.
  • the area (17, 18, 19) facing the inlet side is widened in the shape of a truncated cone towards the inlet side, an angle of approximately 8 ° to 10 ° to the axial being provided. This measure prevents the thread from moving in the wrong direction.
  • the funnel jacket (13b) is designed as a truncated cone which widens in the direction of the thread.
  • the truncated cone is inclined between 2 ° and 4 ° to the axial.
  • a cop (20) is also wound onto the sleeve (21), which has the usual cop structure.
  • the funnel (10) has a funnel jacket (13c) which is continuously cylindrical in the thread running direction after the mouth (14). As shown in Fig. 3, this funnel (10) is also used to produce a conventional cop (20). As already mentioned, the funnel (10) therefore runs with one of the respective circumferential speed dependent on the winding diameter, ie it is constantly decelerated and accelerated again.
  • the hopper (10) it is possible to use the hopper (10) to also wind a cop (22) on a sleeve 823), which consists of parallel windings, as is known, for example, for roving bobbins.
  • the winding speed changes only gradually, so that the hopper (10) is gradually accelerated accordingly. However, it does not alternately accelerate and decelerate.
