A net chain driving structure includes a conveying net chain. The conveying net chain includes a plurality of chain links successively inserted in a conveying direction, a plurality of lugs spaced apart from each other are arranged on two sides of the chain links, an end portion of the lug is an arcuate face, a meshing groove is disposed on the chain link, the meshing groove is spliced by an open slot provided on a back side of the chain link and the lugs on the adjacent chain links, a gear in transmission meshing with the meshing groove is disposed on each end of the conveying net chain, a tangent plane tangential to the arcuate face is disposed on the arcuate face of the lug, and transmission contact toothed surfaces of the tangent plane and the gear are attached to each other in parallel during meshing transmission.

A modular conveyor belt module includes a base body extending along a first direction transverse with respect to the transport direction, between two opposite lateral faces. The module includes upper and lower surfaces; two opposed longitudinal edges; hinge elements projecting respectively from the two edges along a second direction. Each of the first and second hinge elements is crossed by a first and second hole, respectively, the axes of the holes being parallel to the first direction. The holes are each coaxial to each other. The first hinge elements interpose the second hinge elements of another module with the respective holes coaxially aligned. The hinge elements are interposed to each other leaving free spaces to receive a roller. Each roller projects with a portion from the upper surface, the plane parallel with respect to the two directions and tangent to the portion of the rollers projecting from the upper surface.

A conveyor chain for a pallet belt of a moving walkway is described. The conveyor chain comprises multiple elongate chain links, which are arranged behind one another at a chain pitch, and which can be subjected to a tensile load by means of link pins and are coupled so as to be pivotable about a longitudinal center axis of the respective link pin transverse to the longitudinal direction. The conveyor chain furthermore comprises multiple elongate connecting elements that are likewise arranged behind one another and pivotably coupled to one another. Each of the connecting elements is coupled to an associated first link pin with a front end and coupled to an associated second link pin with a rear end. In this case, a connecting element pitch between the first and the second link pin amounts to an integer multiple of the chain pitch.

A colorized and tribologically modified polyoxymethylene polymer composition is disclosed. The polyoxymethylene polymer composition is comprised of a polyoxymethylene polymer in combination with at least one tribological modifier. The tribological modifier may include a fluoropolymer. The polymer composition further contains at least one coloring agent in combination with a color stabilizer. The color stabilizer has been found to dramatically improve color consistency. Polymer articles molded from the polymer composition not only have excellent surface appearance but have excellent low friction characteristics when tested against aluminum.

A modular conveyor belt including a plurality of rods, a plurality of rollers, and a plurality of links. Each link includes a main body, a plurality of link hinge members, and a plurality of roller hinge members. Each roller hinge member has an opening therethrough configured for receiving a corresponding rod and a recessed retainer configured for receiving and retaining a corresponding roller.

An apparatus for conveying an object in a conveying direction includes a conveyor comprised of a plurality of modular links adapted for interconnecting to form a chain. At least one of the links comprises a rounded upper portion forming an apical region for contacting and supporting the article for conveyance along at least a forward run in the conveying direction. The at least one link further including a forwardly projecting portion associated with a first transverse connector forming a part of the upper portion and a rearwardly projecting portion associated with a second transverse connector forming part of the upper portion. The first and second connectors may be staggered in the conveying direction and a direction transverse to the conveying direction. Further aspects pertain to a link with an apical engaging structure, and a sprocket with a removable tooth.
