A method for adhering together rubbers to be adhered including a rubber composition containing an ethylene--olefin copolymer, an organic peroxide (X1), and carbon black (Y1), using a rubber for adhesion including a rubber composition containing an ethylene--olefin copolymer, an organic peroxide (X2), and carbon black (Y2) at an adhesive interface, wherein contents of the organic peroxide (X1) in the rubber to be adhered and the organic peroxide (X2) in the rubber for adhesion are predetermined contents, and a content ratio (X2/X1) of the organic peroxide (X2) to the organic peroxide (X1) is from 1.20 to 2.00.

A link belt is provided wherein the link belt is formed of a plurality of links forming a series of links in successive overlapping relation. The link belt includes a first end having a first connector and a second end having a second connector so that the first connector is connected with the second connector to form a continuous loop of link belt. The link belt is formed by applying a lateral force against the assembled link belt while the link belt is under an axial tension to stretch the belt. After the step of stretching the belt, the first connector is connected with the second connector to form a continuous belt.

Methods include providing a plurality fabric material layers, applying a plastisol layer between each fabric material layer forming plurality fabric material layers thereby creating a belt carcass, pressing the fabric material layers together with the plastisol layer(s) at a pressure of at least 5 psi to produce a preformed fabric carcass while heating the preformed fabric carcass while heating the preformed fabric carcass to a temperature which is within the range of about 360 F. to about 450 F. for a period of at least 6 minutes, disposing a thermoplastic elastomer polyvinyl chloride alloy composition onto the upper and lower surfaces of the fabric carcass, pressing the thermoplastic elastomer polyvinyl chloride alloy composition onto the upper and lower surfaces of the fabric carcass, and splicing opposing distal ends of the belt in a stepped splice configuration. The layers may be devoid of covering strips of lattice fabric disposed adjacent an abutment of any proximally positioned fabric layer.

A portable conveyor belt splicing apparatus is provided that includes an upper press assembly and a lower press assembly which include, respectively, upper and lower platen assemblies. The upper and lower press assemblies may each include a forced air cooling system for rapidly cooling platens of the platen assemblies. The upper and lower press assemblies may include insulating assemblies with resilient members that support the upper and lower press assemblies. The resilient members provide structural support and insulate the platens from the frame which reduces the power required to heat the platens. In one form, the apparatus includes a power supply circuit that can alternate between providing power to upper and lower heaters in response to the apparatus being connected to different types of standard power supplies. Further, the power supply circuit permits the use of a single recipe for a particular belt irrespective of the type of power supply.

In a method for manufacturing such a modular belt link, a mold having a mold cavity is used comprising a number of U-shaped profiles, which are configured and arranged such as toafter injecting polymeric material into the mold cavityform an aperture in each of the link ends by providing for each link end at least two laterally adjoining, partly overlapping oblong U-shaped recesses which are alternately oriented such that the open end of one of the U-shaped recesses opens in the top support surface and the open end of an immediately adjoining U-shaped recess opens in the bottom surface. The invention relates also to a modular belt link manufactured with such a method and a modular conveyor belt comprising such modular belt links.

An endless conveyor belt loop includes a conveyor belt that has an elongated body and a substantially uniform width. The ends of the conveyor belt each include a splice formation extending across the width of the conveyor belt that are each configured to mate with the other. A thermoplastic connector is thermally engaged between exposed surfaces formed by the splice formation at the ends of the conveyor belt. When the splice formations are aligned, the thermoplastic connector is thermally engaged and continuously interconnected between the ends for conveyor belt to form a seamless end connection. The thermoplastic connector comprises a thermoplastic copolyester elastomer.

A belt splicer for splicing butt ends of thermoplastic belts together. The splicer uses a plurality of cranks in conjunction with heavy springs to close and rapidly open jaws holding butt ends of a belt in place against a heating wand for melting and against each other for welding the melted ends together. The rapid opening of the jaw also lowers the wand, which is locked in place by a wand lock during the melting of the butt ends.
