A tension-link of the belt-splicer is based on a rope-loop of high-strength synthetic fibre, wound around bosses. The bosses and the loop are encapsulated in moulded plastic. The link connects cross-beams of the splicer. The link includes couplings which permit rotation when the beams deflect in bending. The links can be stored inside the hollow interior of the beams. The couplings include eccentrically-mounted blocks that can be orientated to adjust the length of the link.

A mobile vulcanizing press including a bottom box and a top box, which can be arranged one above the other with material to be vulcanized in between. The bottom box and/or the top box has/have at least one first bolt receiving section, in which a tension bolt can be pivotally located and at least one detent point is located on the bottom box or the top box, such that a detent means of the tension bolt can engage in the at least one detent point in at least one predetermined pivoting position of the tension bolt.

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.

The invention relates to a drive belt connecting device for the tension-resistant connection of flat drive belt end sections (93, 94), which drive belt connecting device comprises a multi-part connecting body (41), which has connecting parts (1, 2, 3) and a connecting chamber (42), which accommodates the drive belt end sections (93, 94), which have at least one first belt flat side having a belt surface profile (911) in an overlapping arrangement for tension-resistant connection. A first outer connecting part (1) and a second outer connecting part (2) bound the connecting chamber (42), in which an inner connecting part (3) having inner connecting surfaces (301, 302) is arranged. The inner connecting surfaces and outer connecting surfaces (101, 201) of the outer connecting parts (1, 2) can be placed onto the drive belt end sections (93, 94). A fastening means (5) fastens the outer connecting parts (1, 2) to each other at a limited fixed distance. An inner connecting means (30) connects the inner connecting part (3) to at least one of the two outer connecting parts (1, 2) for connection that is secure in the belt tension direction. A flat drive belt (90) is connected to a circulating continuous flat drive belt (90) by means of at least one said drive belt connecting device (4). A conveying device (7) comprises two such drive belts (901, 902), which can be guided and driven along a conveying path (78) and a return path (79) to circulate together and in parallel, wherein one conveyor belt (75) is formed by a series of transport elements (73) arranged in parallel and transport blocks (74) fastened onto the two drive belts (901, 902) to support said transport elements. Connecting bodies (41) of the drive belt connecting devices (4) are configured as transport blocks (74).

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 belt splicing machine includes two pressing plates respectively arranged at an upper side and a lower side and opposite to each other. The pressing plate located at the upper side and the pressing plate located at the lower side are respectively mounted on a support located at the upper side and a support seat located at the lower side. A heating sheet, a clamping plate, and an airbag are successively arranged between the pressing plate located at the upper side and the support seat from bottom to top. The clamping plate is fixedly connected to the pressing plate. A connecting plate is arranged between the airbag and the clamping plate. The clamping plate is fixedly connected to the support seat. A plurality of elongated grooves are formed on the lower side surface of the connecting plate along its length direction.

In one aspect, a conveyor belt fastener is provided having a rigid body made from a strip of cold-rolled or cold-drawn material such as steel. The body has an upper plate portion, a lower plate portion, and loop portions connecting the upper and lower plate portions. The upper and lower plate portions each have a variable cross-sectional thickness laterally thereacross including raised walls projecting outwardly and ribs projecting inwardly. The fastener has at least one attachment member, such as a staple, for connecting the plate portions to a conveyor belt end and the raised walls protect the staple once driven into the conveyor belt end.
