Abstract: A composite sheet includes a fabric that is at least partially embedded in a polymeric sheet. The fabric includes longitudinally extending warp yarns and laterally extending weft yarns, with there being one or more pairs of substantially spaced apart, yet adjacent, warp yarns. For each pair, the two warp yarns are sufficiently spaced apart from one another so that the composite sheet can be longitudinally slit between and distant from the two warp yarns, to provide one or more sections of the composite sheet that can be used as conveyor belts. The warp yarns are not exposed at the cut edges.

Abstract: An endless treadmill belt includes a bottom-ply fabric that at least partially forms a bottom surface of the belt, and the bottom surface of the belt is for sliding across a treadmill deck. The bottom-ply fabric includes textured synthetic yarns that at least partially form the bottom surface of the belt. A solid lubricant composition is impregnated in the bottom-ply fabric. The solid lubricant composition is a mixture that includes higher and lower viscosity lubricants and a binder.

Abstract: An endless treadmill includes a bottom-ply fabric that at least partially forms a bottom surface of the belt that is for sliding across a treadmill deck. The bottom-ply fabric has warp yarns that at least partially form the bottom surface of the belt, with a large number of these warp yarns, and preferably all of these warp yarns, being less than about 1000 denier, or more preferably about 500 denier or smaller. In addition, the warp yarns that at least partially form the bottom surface of the belt are twisted about 2.5 complete turns per inch, or less. A solid lubricant composition is preferably impregnated in the bottom-ply fabric. The solid lubricant composition includes a wax mixture and it optionally further includes a lower viscosity lubricant, such as silicone. The wax mixture may include a vegetable wax and a mineral wax, such as a mixture of paraffin wax and carnauba wax.
