专利摘要:
The invention relates to the papermaking industry and makes it possible to increase the reliability of the product. A flat product consists of a plurality of spirals of resilient plastic or metal wire that are held together by inserting rods. The product is mainly used in the form of mesh or sectional tape for paper machines and is designed in such a way that the supporting shelves of the coils of the coils have a flat bearing surface, which is wider, than the diameter or width of the wire of the apical arc of the mounting section. The arc-shaped fastener sections connect the opposite guide and carrier shelves. Guide rails may also have flat bearing surfaces. This mesh tape combines the advantages of simply making round wire spirals with good heat transfer and limited breathability due to large surface contacts. 9 hp f-ly, 12 ill. g f

The invention relates to paper for business machines and concerns the construction of a mesh tape.
The purpose of the invention is to improve reliability and work.
Fig, schematically shows a product with a flat structure; spery view; Ia figure 2 - section LA in figure 1; Figures 3 to 5 show the product versions, top view; FIG. 6 - the same, the shelves of the turns to the top of the arc of the spirals have different directions relative to the insert bar, top view; in fig. 7 - section Bb of FIG. 3; FIG. 8 is arc arc; in fig. 9 is a section bb In figure 4; 10 shows a product with a flat structure, a partial section; in fig. 11 - one turn of the tape with a partial section of the shelf; in fig. 12 - section GGD 11.
Figure 1 shows the area of the product 1 with a flat structure. The flat product itself, presented in the form of a rough flat, can be of any length or even any width, which is schematically
The material of the edge fastening 15 15 on the bottom side must coincide with the bottom surfaces of the spirals 3 and 4 in order to make it possible to securely fit the guide and transport rollers. On the contrary, the material of the marginal fixings 15 may slightly protrude above the upper surface of the carrier flange 6 of the coil. However, the upper bearing surfaces 12 of the carrying shelves 6 turns can also coincide with the upper surfaces of the edge fixings 15 (Fig. 2). Shelves 6 and 7 turns, as well as vertex arcs 8, respectively, of the outer zones of the spirals 2-4 are embedded in the material designated by two vertical lines B in the center of the image. This, due to the 30 marginal fastenings 15, the product can be used as in FIG. 3. It can be seen that below are the retaining mesh for papermaking machines.
A flat product consists of separate spirals 2, which can be, for example, right-like spirals 3 or 1 left-like spirals 4. Neighboring spirals are hinged to each other with steel bars 5, The spirals themselves are made of elastic Goy plastic or metal wire. They consist (Fig. 11) of the supporting shelves 6 turns and the opposite guide shelves 7 turns. The shelves of the turns are connected to each other with the help of the apical arches 8 of arcuate fasteners,
shelves 6 turns pass opposite guide shelves 7, which, unlike support surfaces
35 12 have a circular cross section 16, and, as seen in FIG. 12, may also have an oval cross section 16a or a cross section. 16c triangular shape.

The wire from which helix 3 or 4 is made is elastic
45 plastic or metal wire 19, whose diameter 20 in some examples of embodiments of the invention is approximately the same as the diameter of the apical arc 8,
The Iel (separate and vertex arcs 8 have gaps 9 which enter along the One vertex arc of the adjacent spiral. Due to this, there is a blocking zone 11 between two adjacent spirals (FIG. 10)). The vertex arc 8 of the neighboring spirals form together with the rod 5 a joint in the form of a hinge,
Bar 5, like the material of the spirals, can be plastic or metal.
is placed parallel to the axis of the spirals.
The top-lying shelves of the 6-turn flanges have flat bearing surfaces 12, the width of which 13 is larger than the diameter of the wire 14 or the width of the wire 14a of the apical arches of the 8 mounting sections.
The gap 9 between adjacent apical arcs 8 is larger than the diameter 14 of the wire or the width 14a of the wire of the apical arcs.
The material of the edge fastening 15 5 on the lower side must coincide with the lower surfaces of the spirals 3 and 4 in order to make it possible to safely fit the guide and transport rollers. On the contrary, the material of the marginal fixings 15 may slightly protrude above the upper surface of the carrier flange 6 of the coil. However, the upper bearing surfaces 12 of the carrying shelves of the 6 turns may also coincide with the upper surfaces of the g-mi edge fastenings 15 (FIG. 2). Shelves 6 and 7 turns, as well as vertex arcs 8, respectively, of the outer zones of spirals 2-4 are embedded in the mother

shelves 6 turns pass opposite guide shelves 7, which, unlike support surfaces
12 have a circular cross section 16, and, as seen in FIG. 12, may also have an oval cross section 16a or a cross section. 16c triangular shape.
Opposite flanges 17 of the coils may also have a rectangular cross section 18 (FIG. 3),
The wire from which helix 3 or 4 is made is elastic
plastic or metal wire 19, whose diameter 20 in some examples of the invention is approximately the same as the diameter of the apical arc 8,
Opposite flanges 17 of the coils may also, in various examples of the invention, have flat bearing surfaces 12,
Flat bearing surfaces 12
have wide zones 21, as well as edge zones 22, between which there are sections 23.
The mesh tape (fig. 3) consists of 4 or 3 left-drive and right-turn spirals made. The vertex arcs of the neighboring spirals do not adjoin each other due to tensile stresses similar to the stresses in the spiral spring. This is achieved by the fact that the spirals 2-4 are wound with a certain predetermined pitch and have such a preliminary tension, like tension springs, that the fixed gap 9 between their apical arcs 8 is larger than the diameter 14 or the width 14a of their wire 24. The wires 24 of the apex arcs 8 (Fig. 10) of the spirals 2-4 have a generally circular cross section 25, an oval cross section 25a, a triangular cross section 25b or a rectangular cross section 25c, which is obtained by pressure from the oval wire labeled figure 9 position 26. Irrespective of the form of wire shelves vertex arcs 6 and 17 windings, having flat support surfaces 12 are nearly rectangular cross-section 18.
In order to provide mesh belts with the great possibility of supporting air surfaces and heat transfer, as well as the possibility of machine or handicraft production, the width 21 of the flat support surfaces can reach up to two diameters 14 or the width 14a of the apical arc wire 8. In another example, the width 21 of a flat supporting surface 12 and shelves 6, 17 of turns having the same supporting surfaces are two or more times the diameter 14 or the width 14a of the apical arc wire 8. The ratio of the widths e is selected depending on. application areas of the flat product.
FIG. 4 illustrates an exemplary embodiment in which all the spirals are left-entrance spirals 4, and FIG. 5 shows an exemplary embodiment in which all the spirals are right-handed spirals 3. The exemplary embodiment of FIG. 5 shows that the edges 22 of the adjacent flat supporting surfaces 12 fit tightly against each other.

By varying the shape and width of the 21 flat bearing surfaces 12 and due to the resulting changes in the distance 23 between the flat supporting surfaces 12, for example, during papermaking, the air flow passing through the flat product can be varied.
FIG. 6 shows an example of execution in which the shelf 6 turns or the opposite shelves 7 and 17 not shown form insertion rods 5 differing from 90 angle d, and the apex arches 8 spirals 2-4, on the contrary, form an angle p approximately equal to 90 °. By means of this flat product version, an air passage area with an even smaller cross section may be provided than with other examples of execution. FIG. 7 and 9 allow the dimensions of the individual helices to be determined in detail. FIG. 7 shows that the carrier flanges 6 of the windings have an almost rectangular cross-section 18, thereby creating flat bearing surfaces 12. The width 21 of these carrier shelves 6 windings is chosen so that there is some clearance between the edges 22. This distance is fixed.
Opposite guide shelves 7 turns have (Fig.7) a circular cross section 25.
FIG. 8 represents the various cross-sectional capabilities of position 25 in FIG. 7. I
In the exemplary embodiment of Fig. 9, the carrier shelf 6 of the coil, as well as the opposite coil of the coil 17, has a rectangular cross section 18. The vertex arcs 8, on the contrary, have a cross section 26, which can also be made of an oval, triangular or rectangular main cross sections 25a, 25, 25c.
The schematic representation of FIG. 10 allows further determination of dimensional features. Vertical arcs 8 have external edges 27. The total distance between these edges 27 is indicated by 28. It is specified, double diameter 14 or double width 14a of the top arc 8, diameter 29 plug-in rod 5 and gap 30 between the top arc
