A belt and belt connector is provided for forming a continuous belt loop. The belt connector includes a first element insertable into a first end of the belt and a second element insertable into a second end of the belt. The first element may include exterior threads for positively engaging the interior of the belt. Additionally, the belt connector may include a connecting link that connects the first and second elements so that the first and second elements are pivotable relative to one another. Additionally, the connecting link may be configured to that the first element is pivotable relative to the connecting link about a first pivot axis and the connecting link may be pivotable relative to the second element about a second pivot axis that is transverse the first pivot axis.

A conveyor belt includes a first outer sheet disposed on a loadbearing side of the conveyor belt, a second outer sheet disposed on a drive side of the conveyor belt, and an embedded tension-member system disposed between the two sides, which is in the form of cords running parallel in the longitudinal direction of the conveyor belt. The tension-member system includes steel and, prior to vulcanization of the conveyor belt, an expandable coating which, after vulcanization of the conveyor belt, has a pore structure provided to at least portions of the tension-member system. The sheets are formed from a polymeric material with resilient properties. In some aspects, the volume of the coating after vulcanization is from 30 to 5000% higher than prior to vulcanization. The coating may contain at least one of a blowing agent and/or microbeads.

An object is to provide a polyurethane elastomer excellent in strength and surface smoothness. To attain the object, a urethane composition including a certain prepolymer, a plasticizer and a crosslinking agent is provided.

A length adjusting device includes: a body having sides extending in spaced relation to one another, the sides defining respective planes; a first cam operably assembled in relation to the body and having a first proximal cam end positioned between the sides; a second cam operably assembled in relation to the body and having a second proximal cam end positioned between the sides and adjacent to the first proximal cam end; an axle that rotatably attaches the second cam to the body; a channel formed by a space between the cam ends; a handle attached to the body and rotatable from a first position to a second position about a rotation point upon application of a first force; wherein the body is configured to rotate with respect to the second cam to expand the size of the channel upon the application of the first force exerted on the handle.

A resin belt includes: a plurality of teeth disposed at predetermined intervals along a longitudinal direction of the belt on a running surface of a belt body made of a thermoplastic resin; and a cloth covering the teeth, characterized in that: the cloth is a woven cloth obtained by weaving a thermoplastic synthetic resin fiber used as a warp yarn in the longitudinal direction of the belt and a fluorine resin fiber used as a weft yarn in a width direction of the belt; and a percentage of the fluorine resin fiber exposed on a side of a cloth surface of the teeth is 50% or more per unit area, and a percentage of the fluorine resin fiber exposed on a side of a bonded surface with the belt body is 50% or less per unit area.

A resin belt includes: a plurality of teeth disposed at predetermined intervals along a longitudinal direction of the belt on a running surface of a belt body made of a thermoplastic resin; and a cloth covering the teeth. The cloth is a woven cloth obtained by weaving a thermoplastic synthetic resin fiber used as a warp yarn in the longitudinal direction of the belt and a fluorine resin fiber used as a weft yarn in a width direction of the belt. Crimp of the thermoplastic synthetic resin fiber used in the longitudinal direction of the belt is greater than crimp of the fluorine resin fiber used in the width direction of the belt.

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.
