Definitions

• This invention relates to improvements in Fourdrinier wires used in Fourdrinier paper making machines and the object is to strengthen the marginal portions of the wire to prevent the breaking and checking to which these portions of the wire are subjected under service conditions, especially in the case of Fourdrinier machines operating at the higher speeds now em- .ployed -ering the warp and weft strands of the wire and lling the intervening meshes.
• the type of lm formed by the selected coating material should be one which is inert, water resistant, flexible and possesses high tensile strength.
• FIG. 1 is a plan view of a portion of the length of the Fourdrinier wire having its side edges reinforced in accordance with the invention and,
• Fig, 2 is a transverse sectional view taken substantially along section line 2 2 of Fig. 1.
• 5 designates a Fourdrinier wire having its side edges reinforced by plastic reinforcing material B which may be applied in any suitable way to completely cover the warp and weft strands of the wire and to fill the intervening meshes as shown to advantage in Fig. 2.
• Each edge of the Fourdrinier wire may be reinforced by applying a single preformed covering strip of plastic material and subjecting the wire and the covering strip of plastic material to heat and pressure whereby the plastic strip is pressed around the warp and weft strands to completely cover these strands and to fill the intervening meshes.
• each edge of the Fourdrinier wire may be reinforced by sandwiching it between two strips of plastic material and subjecting the resulting sandwich assembly to heat and pressure whereby the material of the strips is pressed into the meshes of the wire and united near the centre of the thickness of the wire.
• scalloped edges 6b of the reinforcing material 6 be contoured so as to present long sweeping reverse curves 6c, but it will be understood that the exact contour of these edges is subject to suitable variations, the main consideration being the avoidance of straight edges which, as previously stated, have been found to promote cracking of the wire along and adjacent to such straight edges.
• edge-reinforcing material is shown applied to a Fourdrinier wire of plain weave but it will be understood that the invention is equally applicable to Fourdrinier wires made with a twill weave or any other type of weave.
• a Fourdrinier wire having its side marginal edges reinforced by covering strips of plastic material presenting scalloped inner edges.
• a Fourdrinier wire having its side marginal edges reinforced by plastic material covering the warp and weft strands of the wire and lling the intervening meshes, the inwardly facing edges of the plastic material at each side of the wire being contoured to present a series of long sweeping reverse curves.
