LINKED CONVEYOR BELT AND METHOD OF MANUFACTURING A LINKED CONVEYOR BELT
A conveyor belt is provided that includes a series of linked elongated support members, which extend transverse to the conveyor belt and are arranged one behind the other in a longitudinal direction of the conveyor belt. The conveyor belt includes a first and a second support member, which are adjacent and partially inserted into each other. The first support member includes a first part and a second support member includes two second parts, wherein the first part is inserted between the two second parts. The first part includes a through-opening that extends transverse to the conveyor belt. At least one of the second parts includes a pin which extends transverse to the conveyor belt, and which is arranged in the through-opening. The pin is integrally formed with the second support member. The adjacent support members have been manufactured in a coupled state, preferably using an additive manufacturing process.

Belt splicing apparatus and method
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.

Conveyor belt, in particular spindle tape, with ultrasound or laser cut lateral sides
A conveyor belt, power transmission belt or machine tape (1) being open-ended with two ending edges (6, 7) and with a longitudinal length (L) in a longitudinal direction, comprising: a) two parallel lateral edges (1a, 1b) running in said longitudinal direction, and being spaced apart from each other by a transversal width (W); b) a first textile layer (2); c) a first coating layer (3); and optionally d) one more through holes (5) perforating the belt through its overall thickness (T), each of these through holes (5) being formed by a hole edge (5a); characterized in that i) the first textile layer (2) comprises fibres or filaments of a thermoplastic and/or the first coating layer (3) comprises a thermoplastic or thermoplastic elastomer; and ii) the lateral edges (1a, 1b) are ultrasound-cut or laser-cut and/or the optional hole edge(s) (5a) is(are) laser-cut. The belt or tape has melt-sealed edges, can be made endless by conventional end-joining and can be used in fluff-generating environments, such as a spindle tape.

Seamless end connection for conveyor belts
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.
