Anti-stick easy-release conveyor belts
A conveyor belt includes a cover layer defining a load carrying surface, a pulley engaging layer disposed parallel to the cover layer, and a carcass containing a reinforcement layer, where the carcass disposed between the cover layer and the pulley engaging layer. The cover layer is formed by curing an admixture containing at least a cross-linkable functionalized polyethylene and polyethylene polyolefin. According to the disclosure, the cured admixture is effectively maintained within the cover layer during use of the conveyor belt. In some cases, the load carrying surface maintains a wet clay cleanability value of greater than 3, or even a wet clay cleanability value of greater than 4.4. The cross-linkable functionalized polyethylene may be a cross-linkable oxidized polyethylene. In some aspects, the cross-linkable functionalized polyethylene does not form a polyethylene film upon the load carrying surface.
Conveyor belt
The present invention allows the friction of the belt with the slide table to be abated as well as restrains dusts from occurring. The conveyor belt 10 for carrying a transported article mounted on the surface thereof comprises: a belt main body 1; and a lower surface layer 3 to cover the lower surface of the belt main body 1, in which the lower surface layer 3 is provided with a projective surface 4b in which a plurality of projections 4 whose peak portions 4a are formed into a curved surface shape.

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.

Wear Resistant Polymer Composition Having Improved Surface Appearance
A tribologically modified polyoxymethylene polymer composition is disclosed. The polyoxymethylene polymer composition is comprised of a polyoxymethylene polymer in combination with a tribological modifier system. The tribological modifier system may include the combination of a fluoropolymer with a high density polyethylene, such as an oxidized high density polyethylene. The particular formulation provides a synergistic blend of properties. For instance, the polymer composition not only has an excellent surface appearance when molded into articles but has excellent low friction characteristics when tested against aluminum.
Conveyor Belt Specification Determining Method
Provided is a conveyor belt specification determination method. Severity of a use condition of a conveyor belt is categorized into categories. A database in which a permissible range of prescribed characteristics of an upper cover rubber, including wear resistance and cut resistance, for each of the categories is set is created; a degree of influence of representative rubber physical properties, which affect the prescribed characteristics, of the upper cover rubber on the prescribed characteristics is ascertained; a category is identified from the use conditions of the conveyor belt on the basis of the database; an appropriate range of the representative rubber physical property is identified for which the prescribed characteristics are in the permissible range in the identified category; and a rubber type for which the rubber physical properties are in this appropriate range is selected as the upper cover rubber.
