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 with sturdy edges capable of supporting the weight of the belt along a carryway. The sturdy edges have bearing surfaces, such as the peripheries of wheels or the faces of wear pads, mounted at the sides of the belt to bear the belt's weight when the belt rollers are not supported on a roller-activation system.

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.

Module (1) for a modular conveyor mat, comprising coupling elements (9) at the front and rear of a body part (4). The coupling elements (9) comprise a series of successive hinge parts (10) and receiving spaces (11), wherein hinge parts (10) and receiving spaces (11) can interdigitate with receiving spaces (11) and hinge parts (10) of a similar module (1) successive in convening direction, and successive modules are hingedly couplable using hinge pins extending transversely to the conveying direction, reaching through hinge bores (13) provided in the hinge parts (10). The body part (4) is provided in the middle with a dividing plane (D) which extends parallel to the sides and along which the module (1) is divisible into two module halves (1A, IB). The pairs of coupling elements (9z) located on the sides are, viewed in the direction of the main axis, implemented with a greater width (B) than neighboring coupling elements of the body part (4). Further, pairs of coupling elements (9d) located on both sides of the dividing plane (D) of the module (1) are also implemented with the same width (B) as the coupling elements (9z) with the greater width (B) located on the sides.

A conveyor module includes a module body with a pair of first link ends extending in a first direction of travel and a second link end extending in a second direction of travel opposite the first direction. Each of the first and link ends has a transverse opening therethrough. At least one of the first link ends has a first mating portion. A pin is configured to be received in the first transverse openings of the module body. The pin has a shaft and a lever affixed at a first end of the shaft. The lever has a second mating portion configured to be rotatably coupled with the first mating portion of the module body, thereby preventing transverse movement of the shaft.

A two-axis modular belt comprising two orthogonal belt loops intersecting at a union on a carryway. The belt is constructed of rectangular belt modules arranged in rows and columns. The modules are interconnected by hinge elements that allow columns of an advancing belt loop to translate relative to the rows of the other stationary belt loop.
