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.

A variety of transmission mechanisms are provided that include split pulleys nested within each other in order to reduce the size of the transmissions, to provide infinitely variable transmission ratios that include forward and reverse ratios, or to provide some other benefits. These transmissions include W-shaped belts, having both contact surfaces that are directed outward from the belt and inward, toward a center-line of the belt, to contact the pulleys with respective different inward- and outward-directed contact surfaces. Accordingly, the surfaces at which the belt contacts the different pulleys may be substantially the same with respect to a hinge or other structure of the belt. This improvement may permit higher levels of power transmission, increased efficiency, and increased transmission lifetime. Additionally, variable-eccentricity variable transmissions are provided wherein the eccentricity of rotation of an inner, nested pulley varies with changes in the transmission ratio of the transmission.

A method for attaching a connector element to a belt end of a conveyor belt, wherein the connector element has a base tier provided with central passages and an adhesive tier disposed on one side of the base tier that produces adhesive under the effect of heat, including (i) disposing the connector element on the belt end of the conveyor belt positioned in a U-shaped deflection that is disposed on averted sides of the belt and on one end side of the belt with the passages positioned in the region of the U-shaped deflection and the adhesive tier disposed so as to face the averted sides of the belt; and (ii) connecting the connector element to the averted sides of the belt, wherein the connector element is adhesively bonded to the belt under the effect of a heated pressing installation on both sides of the belt.

The invention provides a fully modular component based conveyor belt splice with expansible tension links, robust side rails, a component based clamping structure and a modular structurally supported thermal element.

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.

A method for attaching a connector element to a belt end of a conveyor belt, wherein the connector element has a base tier and an adhesive tier which is disposed on one side of the base tier and produces adhesive under the effect of heat, the base tier in a central region being provided with passages, includes (i) disposing the connector element on the belt end, wherein the connector element positioned in a U-shaped deflection is disposed on averted sides of the belt and on one end side of the belt, wherein the passages are positioned in the region of the U-shaped deflection of the connector element, and the adhesive tier is disposed on the belt so as to face the averted sides of the belt (1); and (ii) connecting the connector element to the belt in the region of the averted sides of the belt, wherein the connector element is adhesively bonded to the belt under the effect of a heated pressing installation that is disposed on both sides of the belt.

The present disclosure provides a clip assembly for jointing devices for a conveyor belt that includes a U-shaped clip intended to be secured and straddling an end of a conveyor belt with an overhanging of a front curved portion, or nose of the clip. The clip assembly further includes a tube secured in a front concave portion of each clip and a bracket having two cheeks secured to lateral ends of the tube. The cheeks are joined together at a rear by a connection portion. The securing of the cheeks is obtained by piercings on lateral ends of the tube. Branches of the clips are provided with through-holes to secure the clip with a stem. In one form, the branches of one or more clips in a set of clips are of unequal length.

The present invention relates to a belt or a belt segment having a plurality of strength supports. The strength supports run in the longitudinal direction (X) and are disposed so as to be mutually parallel. A connection element which forms one end of the belt or the belt segment and is configured for connecting to a further connection element of the other end of the belt or to one end of a further belt segment, it being possible for the ends of the strength supports to be held in a force-fitting manner by the connection element by way of press-fitting. The belt or the belt segment includes a part-region of the connection element which is configured as a tool region, in order to serve as a tool part during press-fitting of the ends of the strength supports in the connection element.

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.
