    摘要: A method is described for making a reinforcing wire frame for embedding in a moulded polymer support frame over which woven wire cloth is to be stretched and secured to form a sifting screen. The method involves locating lengths of cut wire substantially equally spaced apart in a jig to form a first array. A second array of lengths of cut wire is located over the first array with the lengths of wire in the second array being substantially at right angles to those of the first array. The lengths of wire in the first and second arrays are resistance welded at points of mutual intersection so as to form a first substantially rectilinear matrix. Lengths of cut wire are located in a jig to form a third array, in which the lengths are also substantially equally spaced apart, and a fourth array of lengths of cut wire is arranged over the third array with the lengths of the fourth array substantially at right angles to the lengths of wire of the third array, and the wires of the third and fourth arrays are also resistance welded at points of mutual intersection to form a second substantially rectilinear matrix.

    摘要: A method of repairing or refurbishing a filter screen is described. The type of screen is defined in the specification. The repair or refurbishment is effected by stripping worn or damaged wirecloth from the surface of the frame and placing fresh cloth over the frame and tensioning it as appropriate. Heat is then applied so as to soften surfaces of the frame over which wirecloth is stretched, so that the latter can penetrate softened plastics material in the surfaces and become embedded therein. The frame and its associated fresh cloth is allowed to cool, after which the applied tensioning is removed. Exposed edges of the wirecloth can be trimmed back to the surrounding flange. Plastics material may be applied to the surface of the frame which is to receive the new wirecloth, before the latter is fitted, to provide additional plastics material for bonding the wirecloth to the frame. Alternatively the stripped frame may be inserted in a mould, and fresh polymer material is injected into the mould so as to reform ridges on the surfaces of the frame similar to those which existed when the frame was first manufactured, before the wirecloth is applied thereto.

    摘要: A sifting screen is described comprising a rigid frame, a first woven cloth of hard wearing metal wire, stretched thereacross and secured thereto, and a second woven cloth having a coarser mesh than the first cloth and being woven from an elongate material of greater cross-section than the first, also stretched across the frame, and secured thereto, below the first cloth, to support the latter against sagging. In accordance with the invention, at least the wearing surface of the material from which the lower cloth is woven is selected to be significantly less hard wearing than that from which the upper cloth is woven, so that wear due to rubbing and vibration during use, occurs to a greater extent in the lower cloth than in the upper cloth. In one example the upper cloth is woven from stainless steel wire and the lower from phosphor bronze wire. In another example the lower cloth is of wire having a coating of an epoxy based material, or Teflon (TM), or Molybdenum Disulphide. In another example the lower cloth is formed from a plastics material or Kevlar (TM) or carbon fibre. The frame may be formed from glass reinforced gas blown polypropylene reinforced by elongate metal reinforcing elements or rods.

    摘要: In a method of and apparatus for manufacturing a filtering screen, a frame of plastics coated metal or reinforced plastics material is located in a jig and at least two sheets of wire cloths are placed over the frame and their edges gripped by pneumatically operated clamps carried by the jig. The clamps are pneumatically driven outwardly of the frame to tension each cloth in orthogonal directions. The tensioned cloths are pressed against the frame and heated in order to bond the cloths to the frame. The heated material is allowed to cool, and after completion of the bonding step the clamps are released, allowing the frame to be removed from the jig. Where necessary the cloths are trimmed back to the edges of the frame. A separate set of pneumatically operated clamps may be provided for gripping all four edges of each wire cloth layer to allow each layer to be individually tensioned.
