Definitions

  • the present invention relates to a method for manufacturing articles made of welded metal wires comprising a peripheral belt.
  • wire articles are of the flat type such as grids. It may also be bulk articles such as baskets used for example in household appliances, refrigerators, freezers, dishwashers, etc.
  • Articles of this type generally include a belt consisting of a single shaped and butted wire, on which is welded the frame of a grid or a lattice set in volume if it is a basket.
  • This technique for grids and for baskets, requires two production lines: - a line for the manufacture of the belt and - a line for the preparation of the trellis and for the assembly of the belt on the folded trellis.
  • the positioning of the belt on the trellis requires complex and specific tools for each type of basket.
  • the present invention provides a process for the production of wire articles which makes it possible on the one hand to simplify the manufacture and, on the other hand, to improve the quality of the products.
  • the method according to the invention also has the advantage of accommodating simple machines and tools which are suitable for a wide variety of articles. Changes in the series of articles can, thanks to this process, be carried out in a few minutes.
  • the method according to the invention consists of - welding, on wires constituting the base frame, two half-belts in the form of straight wires which are parallel to each other, - carrying out at least one folding operation in order, in particular, to shape said wires and bring their ends together in order to form the belt, - to assemble by welding, end to end, said ends of said half-belts.
  • the method according to the invention makes it possible to produce the articles on a single production line.
  • the initial phase of preparation and scheduling of the different wires can be carried out with great precision since they are straight wires.
  • the threads constituting the half-belt are distributed automatically from a large storage store for example, in the same way as the other threads constituting the frame and / or the trellis.
  • these weft or mesh wires can be prepared at their ends with a chamfer, to better accommodate a protective coating.
  • This method according to the invention does not prevent other operations, such as adding wires in the corners for a grid, or, in the case of baskets, from performing, depending on the type of article. to carry out additional welding operations for the other wires of the trellis after folding, or also welding operations for added elements such as handles or also operations for folding the belt itself, etc.
  • the invention also relates to the product obtained by the process and in particular a grid consisting of parallel wires, welded to the belt, which belt consists of two half-belts assembled by butt welding after folding the ends of said half-belts.
  • the invention also relates to a basket consisting of a welded and then folded mesh, the belt of which consists of two welded half-belts. end to end.
  • the invention also relates to a basket made up of a welded and then folded mesh, the belt of which consists of two half-belts welded end to end.
  • FIG. 1 represents a simple grid consisting of wires 1 forming a weft, and of a belt 2 on which said wires are welded 1.
  • the belt 2 consists, as shown in FIG. 2, of two rods each forming one half of the belt . These rods 2 'and 2' 'are straight and parallel to each other at the start; they are soldered with the ends of the wires 1. They can be the same length or have a different length.
  • FIG. 3 The making of a basket is illustrated in figures 3 to 9. It consists, firstly, as shown in FIG. 3, of positioning the wires constituting the trellis; these wires cross at right angles and are welded together. There are wires 1 constituting crosspieces and wires 4 which are parallel to the half-belts 2 'and 2''. These half-belts are made up of rectilinear and parallel threads, of the same length or of different length as the case may be.
  • the wires 1 are welded to the half-belts 2 ', 2' '.
  • FIG. 4 consists in bending the wires 4 to produce two sides of the basket.
  • the bending axes of the wires 4 constitute edges of the bottom of the basket.
  • Figure 5 shows the folding of the half-belts 2 'and 2' '.
  • FIG. 6 represents the operation of folding the wires 1 to form the other two sides of the basket and, simultaneously, positioning the two half-belts 2 'and 2' 'already folded before, in the same plane which constitutes the upper edge of the basket.
  • Figure 7 shows the welding operation to butt the ends of the two half-belts.
  • the welding point 3, on each side of the basket, is preferably located between two wires 4.
  • FIG. 8 represents the operation of welding the wires 4 constituting the two folded sides at the level of the operation illustrated in FIG. 4; these wires 4 are welded to the belt 2 which has just been assembled.
  • FIG. 9 illustrates additional operations such as for example the fitting of handles 6 on the peripheral belt 2.
