Definitions

  • the invention relates to a method and devices for winding and forming coils made of elastic plastic or metal wire, the turns of which consist of essentially straight winding legs and head arches connecting them, preferably for joining flat structures, such as screen or link belts for paper machines or the like
  • the wire coils have a tension spring-like pretension in such a way that the respectively 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 helices. 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 that are inserted into the coils with relatively little effort. 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.
  • the present invention has for its object to develop a method and devices with which such spirals can be easily produced.
  • 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 to be widened in accordance with the turn distances caused by the separation.
  • Which manufacturing method is used in detail 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 if spirals are used in which only the straight winding ash 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 facing surfaces of the head arches is greater than the width of a head bow. As a result, the head arches lie loosely and loosely and without tension in the tension side by side.
  • a modified winding or manufacturing process for coils is characterized in that the wire from a wire supply is first wound to windings migrating away from a winding cone with closely spaced head bends and parallel, straight winding legs, and all straight winding legs lying on one side of the windings - possibly after a heat treatment and a separation - preferably by machining, with a flattening, whereupon the coil formed in this way is collected into a coil supply.
  • the coils 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 winding legs need to be flattened, but that, as in the exemplary embodiment described above, some or more winding legs can also be provided between flattened winding legs, which 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 also be brought to the same width and / or be provided with flats of the same width.
  • one or both straight turn legs of each turn are open brought a width that is more than twice as wide as the original wire diameter of the head bends.
  • the turn spacings will be selected so that the turns of the helixes can be fixed with turn spacings, which allow tension-free juxtaposition of the head arches 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 stock can be carried out in a device designed as a single machine .
  • the invention also relates to devices for winding and forming coils made of elastic plastic or metal wire, the windings of which consist of essentially straight winding legs and head bows connecting them, for joining flat structures, for example for use as screen or link belts in paper machines, these devices preferably being used to carry out the previously described methods.
  • a winding device with a fixed winding cone and a fixed mandrel with parallel longitudinal sides and arcuate narrow sides is followed by a device for the effect of heat on the coil which can be displaced along the mandrel, behind which is a device for separating and transporting the windings and is provided for widening their straight winding legs lying against the long sides of the fixed mandrel.
  • a drain wedge is provided behind the fixed winding cone of the winding device on a narrow side of the mandrel. This gives the individual turns when winding. the last turn in each case a drive towards the end of the mandrel, the movement due to this drive is facilitated by the narrowing of the mandrel due to the winding wedge.
  • 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 15, 16 and 17.
  • a device for separating the tightly wound turns of the helix is provided behind the heating tunnel, which includes cutting spaced apart from one another at the desired winding spacing, which, starting in the isolating area, can be guided along the fixed mandrel in the direction of displacement of the helix and at the same time 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 according to claims 20-24 can be provided according to the invention for separating the turns. 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 that the supporting winding legs 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 26-35.
  • 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 cross section of the fixed mandrel 8 is essentially rectangular, the narrow sides 11 also being able to be arcuate.
  • the winding device 6 is a winding device known per se, through which the wire 4 is guided around the fixed winding cone 7. This is indicated in FIG. 2 by arrow 14 of the winding direction.
  • a drain wedge 9 is provided, which is shown in dashed lines in the upper area of Figure 2. It rests on a narrow side 11 of the fixed mandrel 8. Despite the tight winding of the wire 4 in the winding direction 14, its inclined plane permits the turns 16 of the helix 15 to be displaced along the displacement direction 13, which is indicated by an arrow in FIG. 2.
