Definitions

  • the invention relates to a method and devices for winding and forming coils made of elastic plastic or metal wire wound on a supply reel for joining screen belts for paper machines, the windings of which consist of straight winding legs and head bows connecting them, and which are processed prior to further processing a spiral supply can be collected.
  • the wire coils have a tension spring-like pretension in such a way that the adjacent wire coils of the fabric made therefrom are in contact with one another.
  • the coils have no tension spring-like preload.
  • Your wire is torsion-free, which, among other things, is intended to increase the lifespan of the fabric made from it.
  • filling elements are introduced into the spirals. Although this can influence the air permeability, a considerable amount of work has to be accepted.
  • the filling elements usually consist of cotton or plastic parts, which are relatively difficult to insert into the coils. In addition to the increased workload, there is an additional price for the materials used.
  • the gaps between the individual winding legs can be made larger or smaller as required. Not only are advantageous, broad, flat receiving surfaces of the supporting winding legs obtained, but also an air flow of the desired strength, without the disadvantageous consequences of fillers between the winding legs or within the coils.
  • a manufacturing method with a rotating flat winding mandrel (US Pat. No. 3,308,856) has become known, with which although windings are wound with straight winding legs, subsequent processing of the windings cannot be carried out because the mandrel rotates quickly, heating separated windings is only carried out for heat setting and mechanical flattening or widening of the winding legs cannot take place.
  • the object of the present invention is to develop a method and devices with which such helices can be produced in a simple manner.
  • all of the straight turn legs lying on both sides of the turns it is also possible for all of the straight turn legs lying on both sides of the turns to be flattened and widened in accordance with the turn distances caused by the separation.
  • Which manufacturing method is used depends on the purpose of the helix. If a good seal against ventilation is necessary, those filaments in which both straight winding legs are flattened or widened will be used in the manufacture of flat structures. In all other cases, it is sufficient to use spirals in which only the straight winding legs arranged on one side are flattened and widened.
  • the turn spacings caused by the separation of the turns are fixed. This fixing is carried out in the usual way so that the distance between the mutually facing surfaces of the head arches is greater than the width of a head arch. As a result, the head arches lie loosely and loosely next to each other without tension.
  • a modified method for winding and forming coils is characterized in that the wire is first deformed into non-rotating turns with closely spaced head bends and parallel, straight winding legs, which migrate away from the winding cone on a fixed transport path with a rectangular cross section and all of them in a long one
  • the straight winding leg lying on the side plane of the fixed transport path is machined with a flattening and then the turns are separated, whereupon the spiral formed in this way - not rotating - is collected into a spiral supply.
  • the spirals produced by this winding process have on one side only flattened straight winding legs. These winding legs are not widened, so that the distance between them corresponds to the wire thickness.
  • the fabrics made with these coils therefore only avoid point or edge contact, for example with the paper, and allow enough gaps for ventilation.
  • the straight turn legs lying on both sides of the turn can also be provided with a flattened portion.
  • the turn legs need to be flattened, but that, as in the exemplary embodiment described above, there may also be some or more turn legs between flattened turn legs that retain their original shape.
  • the turns are also fixed in the selected turn spacing in the helixes produced by the method described last.
  • the two straight turn legs of each turn can be brought to the same width and / or can be provided with flats of the same width. In special cases, it has proven to be advantageous if one or both straight turn legs of each turn are brought to a width which is more than twice as wide as the original wire diameter of the head bends.
  • the winding spacings will be selected so that the turns of the helixes can be fixed with winding spacings that allow tension-free juxtaposition of the top bends of adjacent helices.
  • the heat effect on the coil, the singling of its turns, the flattening and / or widening of the straight turn legs and the collection of the shaped coil to form a coil supply can take place in a separate device which can be connected to an existing winding device.
  • the winding of the coils, the thermal action and the singling of their turns as well as the flattening and / or widening of their straight turn legs as well as the collection of the shaped coils into a coil supply can be carried out in a device designed as a single machine .
  • the invention also relates to devices for winding and forming coils from elastic plastic or metal wire wound on a supply reel, for joining screen belts for paper machines with a mandrel fastened to a winding cone, and devices for separating and heat treating the cone on the mandrel migrating turns and a collecting container, in which a spiral supply forms to carry out the method.
  • Such a device is characterized in that the winding cone and the mandrel are fixed, that the mandrel has parallel longitudinal edges and arc-shaped narrow sides, that the winding around the mandrel and the migrating away from it on the winding cone giving device for the action of heat, behind which the device for separating the turns is provided, which includes a device for transporting the turns and for widening their straight turn legs abutting on a long side of the fixed mandrel, followed by a fixed collecting container for receiving the helix supply.
  • a drain wedge is provided behind the fixed winding cone of the winding device, on a narrow side of the mandrel.
  • a heating tunnel is provided for the action of heat on the helix which can be displaced on the mandrel.
  • the heat development within the heating tunnel can take place in various ways, for example according to claims 16, 17 and 18.
  • a device for separating the tightly wound turns of the helix is provided behind the heating tunnel, which includes cutting edges that are spaced apart from one another at the desired winding spacing, which, starting in the separating area, can be moved alongside the fixed mandrel in the direction of displacement of the helix and simultaneously transport the helix along the mandrel. It is particularly important that the cutting edges engage in the separation area between the head arches of the turns. The winding is separated and transported from the narrow sides of the coils.
  • Different devices can be provided for separating the turns according to claims 21-25. Which of the methods is used for separating depends not least on the inclination of the individual straight winding legs with respect to the longitudinal axis of the mandrel or the helix. In some cases it is desirable for the load-bearing winding legs to run parallel to the direction of movement of the fabric. In this case, the other turn legs of the turn are aligned particularly obliquely with respect to the central axis of the helix. In other cases, the load-bearing turn legs have the opposite bevel to the central axis of the helix as the turn legs of the turns opposite the load-bearing turn legs.
  • the device for widening the straight winding legs includes at least one hammer or tapper, which is arranged opposite the longitudinal side of the mandrel between the worm wheels or the cutting edges for separating and transporting the windings.
  • the device for widening the turns can be designed according to claims 27-36.
  • the plasticization of the material is made possible before or during the widening by heat.
  • the amount of heat introduced by the hammers into the straight winding legs is sufficient to achieve sufficient plasticity.
  • the thermal energy stored in the heating station is often sufficient to ensure a certain amount of preheating.
  • the device according to claim 38 is characterized in that the winding cone and the mandrel are fixed, that the mandrel has parallel longitudinal edges and curved narrow sides, that behind the winding cone a grinding device as Device for machining flattening of the straight winding legs and then a device for separating and transporting is provided, which is followed by a fixed collecting container for receiving the winding supply.

  • a drain wedge 9 is provided, which is shown in broken lines in the upper area of FIG. 2. It rests on a narrow side 11 of the fixed mandrel 8.
