Definitions

the invention relates to conveyor belts and filtration bands such as felts or stationery covers, consisting of spirals assembled by rods, interweaving of spirals or the like.
conveyor belts or the like are used to form, press, dry.
bands obtained by weaving with or without subsequent fixing of a ply by needling have been used on one or two faces. These woven strips made it possible to obtain good results.
the object of the invention is to remedy these drawbacks by strengthening the edges of strips made up of assembled spirals, arranged in the transverse direction relative to the axis of the strip.
the subject of the invention is a method for reinforcing the edge of a strip consisting of spirals assembled together by their overlapping or by joining rods, characterized in that it consists in introducing the edge of the strip into the ends of the strips. spirals, a reinforcing element which is applied to the ends of the spirals.
the invention also relates to the device obtained by the implementation of the method.
a conveyor belt 1 consists of spirals 2 and 3 arranged in the transverse direction relative to the longitudinal axis of the belt. These spirals 2 and 3 formed respectively in the right direction D and the left direction G are assembled by connecting rods 5 made of synthetic material for example.
the edge of the strip is cut straight parallel to the longitudinal axis.
the ends of the cut spirals are at the same level as the end of the rod 5 connecting the spirals.
the turns of a spiral of reinforcement 10 Inside the spirals in the channel left free and at the edge of the strip, the turns of a spiral of reinforcement 10.
the bottom 11 of a loop of the reinforcement spiral is applied against the ends e 1 of the spirals of the strip and e 2 of the junction ring.
the turns 12 of the reinforcing spiral 10 are maintained inside the spirals 2, 3 of the strip by friction against these spirals.
an additional reinforcement of the selvedge is obtained by introducing a reinforcing wire 13 into the bottom 11 of the reinforcement turns, between the ends e 1 of the spirals of the strip and the reinforcement spiral 10.
the positioning of the reinforcement element 10 inside the spirals 2 and 3 of the strip is further reinforced by coating the edge 18 of the strip over a width L greater than the penetration of the spirals 12 of the reinforcement element 10 (fig .7).
the width of the turns 12 of the reinforcing element 10 must be sufficient for them to penetrate well inside the selvedges 18, a width of 20 mm is suitable.
the pitch of the turns 12 depends on the number of spirals 2 and 3 joined in the longitudinal direction of the strip.
the thickness of the turns 12 of the reinforcing element 10 depends on the space available inside the spirals 2 and 3 of the strip. Too much thickness prevents its introduction into the spirals of the strip. Too small a thickness will not block the reinforcing element 10 inside the spirals of the strip.
the reinforcing element 10 may consist of monofilaments, multifilaments, impregnated braids, metallic threads. It can be covered with multifilament threads. It can be flocked to improve the adhesion of the selvedge impregnation adhesive.
reinforcement element 10 of the selvedges can take different forms.
FIG. 3 represents a variant in which the reinforcing element has a shape having pronounced undulations in a zigzag or accordion folding.
FIG. 5 represents a variant in which the reinforcing element comprises turns 19 of unequal lengths in each spiral of the strip to facilitate their introduction into the selvedges.
an additional reinforcement wire 13 can be inserted at the bottom 11 of the reinforcement coil, in a longitudinal direction, to improve the quality of the reinforcement.
This thread can be a monofilament, a multifilament, a single or twisted or cabled fabric thread, a chain.
FIG. 6 represents a variant of FIG. 2 in which a chain stitch reinforcement 20 connects the turns of the reinforcement element on the selvedge side; the chain, the meshes of which are formed around the spiral threads of the reinforcing element, plays the role of reinforcement and maintains the correct spacing between the turns of the reinforcing element.
Each turn of the reinforcing element can be distant from the previous one by a value equal to the pitch of the spirals of the strip in the longitudinal direction.
the strip can consist of spirals assembled together by their nesting without the use of rods.
the reinforcing element 10 which is introduced into the spirals 2 and 3 at the edge of the strip, is supported only on the ends e 1 of the turns cut from the spirals.
