Definitions
- the invention relates to a machine felt with at least two layers of longitudinal threads having longitudinal threads and an interposed insert as well as with the Layers of fiber covering the outside of the machine felt. It also relates to a method of manufacture of such a machine felt, in which at least two longitudinal threads with the interposition of an insert be placed on top of each other and on the at least one fiber layer is needled.
- a machine felt of the aforementioned type is in US-A-4 781,967. It is built up in modules, whereby a cross thread or between two longitudinal threads a fabric is arranged as an insert. On the outside the and between the longitudinal threads are layers of fibers intended. The individual modules are through Needling of the fiber layers connected to each other.
- Machine felts of the type described above become endless manufactured. Apart from the fact that the length of such machine felts is limited, so it is not used everywhere assembly of the felt is possible for example in the press section of a paper machine difficult. The assembly of a machine felt is easier, if it is finite in length and on has coupling elements on its end faces, via which the ends of the machine felt in the machine with each other can be coupled (see. EP-A-0 261 488).
- the invention has for its object a machine felt of the type mentioned in such a way that he is available in finite form and its end faces with each other are connectable.
- This object is achieved according to the invention in that two layers of longitudinal thread layers have common longitudinal threads, which go over both sides of the insert and the Insert on their front sides with the formation of coupling eyes mounting.
- the basic idea of the invention is that is, the longitudinal threads of at least two layers of longitudinal threads around the front of the insert, so that the two layers are formed by the same longitudinal threads become.
- the longitudinal threads form in the area of the end faces the insert coupling eyes made for the purpose of Connection of the end faces overlapped and in this position can be coupled via a plug wire can. Except for the plug wire, there are no other special ones Coupling elements required.
- the through the coupling seam This causes discontinuity reduced to a minimum. It also results in a simple one Production of the machine felt.
- two layers of longitudinal thread scrim by folding down at least one in double length of the finished machine felt manufactured thread laying module including the insert are formed.
- the ends of the longitudinal threads then butt preferably in the middle of the machine felt.
- Such a shock is avoided if the longitudinal thread is laid form an endless lengthways lay hose, the includes the insert.
- the longitudinal threads are endlessly trained. For example, you can by helical winding of a longitudinal thread can be formed.
- the basic structure of the machine felt according to the invention can be varied in different ways. So there is the possibility that there are more than two layers of longitudinal thread are formed by the fact that several laying units, each consisting of two layers of longitudinal layers with common longitudinal threads are provided. This can for example, in such a way that at least two nesting units are arranged one above the other, whereby one or more deposits between the layers of the lay-up units and also between the layup units themselves can be provided. Alternatively, the layup units also be nested, where here too there is the possibility of multiple deposits to be provided between the individual layers of the layup units.
- the longitudinal threads can be used to form the coupling eyes only one lay-up unit but also that of all lay-up units be used.
- the insert can be a cross thread exhibit. It can also be multi-layered be and additionally have a fiber layer. Also a Longitudinal laid scrims can be part of the insert. Alternatively or in combination there is also a fabric, Knitted fabrics and / or a perforated film or a thread grid in question. To determine the longitudinal thread scrim the fiber layers should be needled.
- a process for making the prescribed machine felt is characterized according to the invention in that that at least one longitudinal thread module in at least double Length of the finished machine felt is produced and that the protruding sections of the longitudinal thread module around the end faces of the insert with the formation of coupling eyes can be folded around and fixed by the longitudinal threads.
- Material are removed, for example by at least an end cross thread of the insert is removed. If there is also fiber material there, it should be removed.
- An alternative method is characterized in that that an endless lengthways lay hose and separated of which the insert is made and that the insert in the enclosed by the longitudinal thread lay hose Space is placed, with the insert being shortened relative to the length of the longitudinal thread laying hose in such a way that coupling eyes formed by the longitudinal thread laying hose are formed on the end faces of the longitudinal thread laying hose.
- the longitudinal thread lay hose can by helically winding at least one Longitudinal thread progressing lengthways and across it getting produced. To stabilize the longitudinal laid scrim needling of the fiber layers should be carried out become.
- the fiber layers can be on one or both sides during or after the production of the longitudinal laid scrim be placed and fastened. Can also on the insert fiber layers attached on one or both sides and then needled.
- Figures 1 to 4 show the production in stages a finite paper machine felt 1.
- the cross thread insert 2 consists of a Large number of juxtaposed and one below the other connected transverse threads - designated by way of example at 4 - whose length corresponds to the width of the longitudinal thread module 3.
- the longitudinal thread module 3 has a plurality of perpendicular arranged side by side to the plane of the drawing Longitudinal threads 5, which are attached to each other and on a fiber layer 6 is glued to the underside thereof.
- the Longitudinal thread module 3 is in the extended position according to Fig. 1 twice as long as the cross thread insert 2. By central support of the longitudinal thread module 3 on the cross thread insert 2 this results in projecting sections 7, 8th.
- the fiber layers 16, 17 and the fiber layer 6 are then in a needle machine needled, whereby the cross thread insert 2 as well the folded sections 7, 8 fixed to each other become.
- the paper machine felt 1 is then finished.
- the paper machine felt is used to connect the end faces 1 brought into the form shown in FIG. 4. there overlap the coupling eyes 9, 10, so that a Coupling channel 20 arises through which a coupling plug wire 21 is inserted. This connects the two end faces. Because of the bevels on the end faces of the non-woven fabrics 16, 17 overlap, so that the Coupling eyes 9, 10 on the outside through the fiber fleece 16 are covered.
- FIG. 5 to 7 is the manufacture of another Paper machine felt 22 shown.
- the individual windings of the longitudinal thread 24 are interconnected. This creates a longitudinal thread upper layer 25 and a longitudinal thread underlay 26.
- a cross thread insert 27 is inserted into the longitudinal thread support 26. It consists of a large number of side by side arranged and interconnected cross threads - exemplified with 28 - and a needled Fiber layer 29.
- the longitudinal extension of the transverse threads 28 corresponds to that extending perpendicular to the plane of the drawing Width of the longitudinal thread tube 23.
- the cross thread insert 27 is compared to the length of the longitudinal thread hose 23 shortened so that on the end faces of the Longitudinal thread hose 23 coupling eyes 30, 31 arise, which are formed by the longitudinal thread 24.
- the coupling eyes 30, 31 enclose free insertion channels 32, 33.
- the Outside of longitudinal thread top layer 25 and longitudinal thread base 26 fiber layers 34, 35 laid on top of each other and needled through with the fiber layer 29. It then the finished paper machine felt 22 is available.
