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.

A bonder and a method for bonding corrugated sidewalls to a thermoplastic belt at a splice joint. Two heating jaw assemblies with complementary and confronting corrugated vertical faces clamp a thermoplastic belt to a base of the bonder with a corrugated sidewall section separated from the belt across a splice joint received in a corrugated slot formed between the confronting vertical faces. Corrugated bonding strips at the bottoms of the corrugated vertical faces apply heat to melt the bottom of the sidewall section on opposite sides to bond the corrugated sidewall section to the base.

A belting connection for attaching a first end and a second end of belting. The belting has a thickness. The belting connection mechanism includes a first stepped region, a second stepped region and a first fastener. The first stepped region is proximate the first end. The first stepped region has a first aperture formed therein. The first stepped region has a first thickness. The second stepped region is proximate the second end. The second stepped region has a second aperture formed therein. The second stepped region has a second thickness. The first fastener extends through the first aperture and the second aperture to attach the first end to the second end. The first stepped region at least partially overlaps the second stepped region when the first end is attached to the second end. When the first end is attached to the second end, the first stepped region and the second stepped region have a combined thickness that is no greater than the thickness of the belting.

A conveyance device includes a conveyance member, a guide, and a rotator. The conveyance member has a conveyance surface with a joint, the conveyance member to convey an object to be conveyed, with the object on the conveyance surface. The guide approaches the conveyance surface and guides the object from or to the conveyance member. The rotator contacts the conveyance surface. The guide displaces in a direction perpendicular to the conveyance surface, in conjunction with displacement of the rotator when the rotator contacts the joint.

A method is provided for adhering prescribed adherend rubbers to one another using a rubber for adhesion obtained from a rubber composition for adhesion containing an ethylene--olefin copolymer (X2) and an organic peroxide (Y2) at the adhesion interface between the adherend rubbers. The ethylene--olefin copolymer (X2) contained in the rubber composition for adhesion contains an ethylene-1-butene copolymer. The ethylene-1-butene copolymer satisfies prescribed values of the number average molecular weight and the molecular weight distribution. The content of the ethylene-1-butene copolymer is from 60 to 100 mass % of the total mass of the ethylene--olefin copolymer (X2).

The invention relates to a method of production for attachment by cohesive bonding of a profile having at least one profile element onto a toothed belt previously produced as a semi-finished product. The toothed belt has a tooth side with a toothing and a toothed belt back located on the back of the tooth side of the toothed belt. In the method of production the at least one profile element is built up layer by layer from at least one first profile element layer and a second profile element layer on the toothed belt back, by the application of an application compound to the toothed belt back at a profile element position by melt layer printing.
