Definitions

  • Machine felts are used for a wide variety of purposes.
  • a main area of application for machine felts are paper machines. There they are used particularly in the press area. They usually consist of a carrier material, which absorbs the tensile forces acting on the machine felt, as well as a needled nonwoven fabric, which ensures a smooth and soft surface and a defined water permeability.
  • the carrier material is often made up of multiple layers. As far as - as in most cases - the carrier material consists of a fabric, the multilayer can be achieved by the provision of several weft planes, which are connected by warp threads, or by several layers of fully formed fabric webs, which are coupled together by binding threads.
  • connection has the disadvantage that the machine felt in the seam area is twice as thick as in the rest of the area, which leads to considerable vibrations. in the otherwise, this connection is not suitable for a carrier material consisting of knitted fabric.
  • Paper machine felts with a warp knit structure as carrier material are described in DE-OS 24 36 293.
  • the warp knit structure is provided with a needled fiber fleece, creating a felt-like surface on both sides.
  • connection of the ends of the paper machine felt belt is problematic since the warp knitting structure at its ends provides only little support for coupling links, for example in the form of wire helices, even if the carrier material is formed in multiple layers.
  • Proposals are made in DE-GM 85 10 220.2, with an alternative being that the carrier material consists of a two-layer spirally wound material web.
  • the joint between the ends of a material web is bridged over a wide area, specifically by changing the position of the material web from the inside to the outside or vice versa. It is advantageous that a direct connection of the ends of the material web can be dispensed with.
  • the invention is therefore based on the object of designing a multilayer machine felt of the type mentioned in such a way that vibrations in the machine are avoided even at high machine speed, but it is also suitable for the Assembly can be opened and finally knitted carrier material can be used.
  • the layers of the carrier material are thus formed by turning over both end sections of the excess length of material web so far onto the central region that at least two layers are formed.
  • the envelope edges that are formed then lie far from the folded-over end edges of the material web, so that coupling links can be attached to the envelope edges, even if the respective material web is not - which would be possible - woven, but instead consists, for example, of warp knitted fabric .
  • a finite machine felt is created, the end edges of which consist of the cover edges connected to one another via the coupling members or - if the connection according to Needles on the nonwoven is opened - can be connected. In the latter case, this means that the machine felt can be inserted into the machine in the open state and only then closed. With this design, vibrations in the machine are also avoided.
  • the machine felt according to the invention is characterized by better tensile strength.
  • the individual layers are formed by turning over the end sections of only one material web.
  • the carrier material can be simply placed one on top of the other or nested one inside the other, the first alternative having the advantage that the layers of the outer material web are made from a finer woven or knitted fabric than those of the inner material web in order to avoid markings.
  • the folded end sections of the material web are opposite with their front edges, this should be done for reasons of symmetry in such a way that they lie in the middle of the machine felt, the folded end sections thus have the same longitudinal extent.
  • the front edges of the folded end sections can extend exactly transverse to the direction of travel of the machine felt. However, it is preferable that the front edges run obliquely to the transverse direction of the machine felt, especially if the machine felt is to be used in the press area of a paper machine. This may still result Vibrations or impacts occurring in the press avoided.
  • a three-ply carrier material results when the folded end sections of the material web overlap over the entire length of the machine felt. If the carrier material is formed from more than one material web, four, five and six-layer carrier materials can be produced with a corresponding combination of the material webs.
  • end sections of the material web are expediently turned over to the same side, even if there is the possibility of turning the end sections once to one side and to the other side.
  • Particularly suitable as coupling members are wire coils inserted into the carrier material, which are brought into engagement when the machine felt is connected in such a way that a plug wire which causes the coupling of both wire coils can be inserted simultaneously through both.
  • Polyamide has proven to be a particularly suitable material for the wire coils.
  • a mesh-resistant warp knitted fabric is preferably suitable as the carrier material for the machine felt according to the invention.
  • the end edges of the end sections should be provisionally attached to the adjacent layer and / or to one another.
  • a method for producing the machine felt according to the invention is characterized in that both end sections of the material web are turned over and with their Front edges are brought together at least up to the same height and that coupling members are fastened in the region of the cover edges before or after turning over and that the coupling members are then joined together to form a seam before the nonwoven fabric is placed on and needled.
  • the machine felt is to be introduced into the machine in the open state, the nonwoven fabric is cut into the top and bottom sides of the seam after needling and lifted off the seam area and the seam is then opened again.
  • This method is characterized by simplicity and also by the fact that the needling of the nonwoven fabric in the manner described also provides a soft covering of the seam, although the seam can then be opened and closed again.
  • the raised part of the nonwoven then lies again over the seam during operation, the direction of travel should always be chosen so that the incision is behind the seam.
  • the end edges of the end sections are temporarily fastened. Furthermore, wire coils should be inserted as coupling elements during the manufacture of the carrier material, which is possible in a simple manner, in particular in the case of knitted fabrics.
  • end edges of the end sections are overlapped up to the cover edges in order to produce a three-layer construction of the material web.
  • a warp knitted fabric is used for the carrier material, the end sections of which are turned over in such a way that the transverse threads of one layer run on a gap to the transverse threads of the other.
  • the carrier material (1) shown in FIG. (1) is produced from a single knitted material web (2).
  • the material web (2) has approximately twice the length of that of the finished paper machine felt shown in FIG. (2).
  • a further upper layer (6) is formed, the end edges (7, 8 ) face each other. Wire coils are inserted into the material web (2) over their entire length in the cover edges (9, 10), this already happening during the manufacturing process.
  • the continuations (13, 14) shown in dashed lines represent a three-layer variant of the carrier material (1). If the material web (2) is produced in a length that corresponds to three times the finished paper machine felt, the end sections (3, 4) overlap completely with the then existing extensions (13, 14), one end section (3) on the Outside and an end section (4) come to lie on the inside.
  • the carrier material (1) is closed to form an endless band by the two wire coils (11, 12), which are matched in thickness to that of the carrier material (1), are brought into engagement in a comb-like manner in such a way that a plug wire can be passed through both as a coupling wire.
  • a nonwoven fabric is then needled and needle-punched onto the outside of the carrier material (1).
  • the needling process then gives rise to the paper machine felt (15) shown in FIG. 2, the extent of the nonwoven fabric (16) being defined by the boundary lines (17, 18) - albeit oversized in relation to the length and width of the paper machine felt (15) - is shown.
  • the plug wire (23) is removed and the fiber fleece (16) above and below the wire helices (11, 12) is provided with incisions (20, 21).
  • the paper machine felt (15) can then be inserted into a paper machine and, after bringing together the ends provided with the wire helices (11, 12), can be coupled again by inserting the plug-in wire (23).
  • the loose flaps of the nonwoven fabric (16) then lie over the seam (19).
