The invention relates to the field of construction and engineering and can be used as a building block for various purposes and as conveyor canvas for various goods, mostly long and flat shape.

The famous wire mesh-type netting (see GOST 5336-80 "Mesh steel braided single") selected by the applicants as a prototype for the first object. This grid is made of separate but interconnected longitudinal parts of the wire, in the form of flat (tapered) spiral forming rhombic or square cells. This related links screwed (woven) into each other, i.e. each longitudinal link is connected to two adjacent longitudinal sections. Each end of prodelin is the being of the grid lie in the same plane.

Nets are made entirely from a single wire. As the wire is advanced material. Mesh wire type "netting" are made on simple semi-automatic and almost no waste.

The disadvantages of the prototype associated with the spiral form of execution units, which are freely slovincians during transportation, installation and operation of the grid. Roll in the collapsed state the parts of the grid cling to each other. When proslavlenii tape during installation parts find each other. Hence the difficulty in its promotion and installation. All of the above leads to the destruction of the grid and reduce its reliability.

Object of the present invention according to the first object is to improve performance and reliability of the grid wire.

Known conveyor webs of wire mesh for U.S. patent 3920117 from 18.11.1975 selected by the applicants as a prototype for the second object of the invention is made of serially interconnected along its width two types of longitudinal parts of the wire. The first type of longitudinal links made zigzag shape. The second type of links made in the form of a flattened helix, which connected ulozhenie.

The need to perform longitudinal links and two types of welding operations in large quantities leads to a high complexity of the manufacturing process of the transport fabric. In addition, it is difficult to weld the ends of the long links, made of thin wire.

The technical object of the present invention according to the second object is to reduce the complexity of the manufacture of conveyor blade, and therefore reducing the cost of manufacture and the expansion of the scope.

According to the first object of the invention the task is solved in such a way that the famous wire mesh, made of serially interconnected along its longitudinal width of the links of the wire according to the invention, the links made with periodically spaced flat loops arch shape, the width of the loop at the base of the smaller outer side of the loop at least twice the diameter of the wire, and the intervals between the loops made in the form of transverse ridges on the flat loops with a height of not less than two wire diameters for girth loops one link loops the next link at the bottom of the tabs.

The external side of the loops of the longitudinal links obrazom, in the known conveyor cloth of mesh wire made of serially interconnected along its longitudinal width of the links of the wire according to the invention, the links made with periodically spaced flat loops arch shape, the width of the loop at the base of the smaller outer side of the loop at least twice the diameter of the wire, and the intervals between the loops made in the form of transverse ridges on the flat loops with a height of not less than two wire diameters for girth loops one link loops the next link at the bottom of the ledges at the ends of each longitudinal link proderty through the loop at successive longitudinal link are bent in the direction of extreme loops its longitudinal link in the plane of the outer sides of the loops and the ends of the mesh are connected by elements made in the form of flat loops of the longitudinal parts of the mesh at the ends of the elements proderty through the loop of the first longitudinal link mesh and bent in the direction of connecting elements in the planes of the sides of the elements.

The external side of the loops of the longitudinal links are made convex or concave.

Both the United izobretatel links on the type of "loop the loop". Sauganash loops in their base eliminates flushing loops. The presence of transverse projections on the longitudinal links restricts the movement of the link along its axis. No link of this form will not be released from the grid during its transportation, installation, when working with any proslavlenii grid. Base flat loops in the expanded state of the grid lie in the same plane. Cross the ledges to create a hinged connection of two adjacent units with the required angular speed, which allows the grid to be freely twisted into a roll in any direction without catching and binding.

Different types of loops longitudinal links with convex or concave outer side allows you to create various modifications of the grid with a variety of characteristics of its hardness and expansion of the use.

The resulting mesh is a new type of weaving with high resistance to samorazvitiyu and samozozercanii that can improve its performance as a trademark of the construction product, convenient for installation works.

The wire mesh may be made of a closed operable in an endless ribbon through many guard members. High stand the EV grid, allow them to set the mesh of the conveyor blade in working position.

The connection of the ends of the fabric into endless belt is carried out using the same elements links on the same hardware. The curved ends of the connecting elements do not extend beyond the height of the projections and do not damage the transported products. The ends of the connecting elements in the form of hooks and ACC hooks into position to form closed loops for loops of the first-level mesh conveyor cloth.

Depending on the type and shape of the transported goods transverse protrusions may perform the role of the supporting part of the canvas, for example, transported flat and long products or are separators between links, creating a nest for the transported long items.

Curved ends of the longitudinal parts of the grid creates an additional barrier and are limiters on the sides of the conveyor.

Various forms of loops (convex or concave outer side loops) lead to pin loops at different contact angle, which allows to obtain a variety of longitudinal rigidity of the grid. For some transporters with crenarchaeota longitudinal stiffness (outside the loops are made convex) allows rotation, when this load is distributed almost over the entire width of the canvas.

The complexity of manufacture of the conveyor blade is significantly reduced, because all parts of the grid have the same shape, does not require welding of the ends of the long links, and for making such cloth can be used wire of any diameter that will allow us to expand the scope of the conveyor blade of the proposed design.

Conducted patent studies have not found a similar technical solutions that allows to draw a conclusion about the novelty and inventive step of the proposed objects.

The domestic industry has all the resources (materials, equipment, technology) necessary for the manufacture of objects. The proposed solution can be widely applicable in industry. The mesh is subject to General building purposes and may be applied, for example, for fencing, securing mining at mines, screening materials, etc.

Conveyor webs of the grid wire may be used in various fields of engineering, where by strength conditions can note is the itsindustry (pastries, biscuits, etc.,), pharmaceutical, fish, glass, i.e., where required small holes in the conveyor belt or it is necessary to ensure thermal stability of the tape in the oven.

The essence of the proposed technical solution is illustrated by drawings, where:

A wire mesh is made of serially interconnected along its width longitudinal parts 1, wire diameter from 0.5 mm to 5 mm Wire can be galvanized, bright, black and raw or burnt. May be in the plastic shell. Links are made with periodically spaced flat loops arched form 2, while the outer side 3 loop 2 can be made 4 or convex concave 5. The width of the loop is adjacent longitudinal parts 1 type "loop the loop". The intervals between the loops 2 are made in the form of transverse protrusions 7 on the flat loops 2. The height of the transverse protrusions 7 should be not less than two wire diameters to be able to girth loops 2 one link loops subsequent link at the base of the projections 8. At the junction of the loops 2 is formed swivel, which allows you to collapse the mesh in roll in any direction. The connection of two adjacent links allows you to take the angle from -160oto +50o. Base flat loops 2 when tense or simply maximized state of the grid lie in the same plane. The ends 9 of the longitudinal links 1 are located along the longitudinal axis of the link 1. In so doing they increase the width of the grid. If necessary, the ends can be bent, as described below, the conveyor bed, or other way.

Mesh width can be up to 2.5 m Length of net per roll - 10 m In agreement with the customer the mesh sizes may be different.

The objects of the invention combined to form a single inventive concept. Conveyor canvas consists of a wire mesh, performed as described above. The ends 9 of each longitudinal element 1 in the proposed conveyor canvas proderty on the link in the plane of the outer side walls 12 at the hinge 11. The ends of the mesh are connected by elements 13, made in the form of flat loops 2 longitudinal parts 1 grid. The ends 14, 15 elements in 13 proderty through the loop of the first longitudinal link 1 grid and are bent in the direction of the connecting elements 13 in the planes of the sides of the elements 16, 17. Mesh conveyor cloth should be made of stainless steel wire.

The applied tensile load on the conveyor cloth in convex form 4 outer side 3 loops 2 stretches the grid and simultaneously reduces its width by a few percent. A prototype of the proposed grid in the form of a square of side 1 m, with cell size of 10 mm, a wire diameter of 1 mm has a modulus of rigidity 3,4104n/M. in practice, this means longer, 44 mm tensile strength of 1500 n For some conveyors require moving conveyor paintings in curved trajectory in the horizontal plane. Mesh with convex 4 external parties 3 2 loops (with a "soft" characteristic longitudinal stiffness) allows such rotation, the external loop 2 are stretched, the inner loop 2 is slightly awkward. But the thrust force in the last (inner loops) sohranyaete 3 loops 2 increases the rigidity of the grid and is applicable to relatively thin wire.

Working movement of the conveyor blade directed toward the loops 2 grid. Reason 6 loops 2 (or the base of the protrusions 7) form the basis of the conveyor fabric that easily overcomes random minifactory on the conveyor. Conveyor canvas can bend around the rollers of the conveyor. The transported product, 18 are located on the tops of the transverse protrusions 7 (as in Fig.6) or slots (cells) between the projections 7.

Roll the finished grid tie wire in the middle and at the edges. Transport and storage grids should be carried out according to GOST 15150-69.
