Abstract: A resin matrix (70) is formed and reinforcement fibers (72) and thermoplastic material (74) are added to the resin matrix (72). The resin matrix (70), the reinforcement fibers (72) and the thermoplastic material are moved through a pultrusion die (76), by pulling on the reinforcement fibers (72), to form a conveyor slat having a top portion (38) and a pair of laterally spaced apart side portions (40, 42) depending from the top portion (38). In the pultrusion die (76) heat is applied to melt the thermoplastic material (74) and cause it to migrate to an outer surface portion of the slat body. A veil (90) of thermoplastic material may be bonded to the surface layer of thermoplastic material.

Abstract: A three-dimensional woven fabric structure is integrally woven by a multi-ply weave having three or more plies, and includes a form defining a plurality of bag portions extending parallel with one another, and arranged in a plurality of rows. The bag portions in each row are defined by two woven fabric plies, the intersection of which along a crossing locus creates a bound portion between adjacent bag portions. Cylindrical bag portions in adjacent rows have a woven fabric ply in common and are interconnected at staggered positions. The fabric structure is creased at midpoints between bound portions whereby the bag portions are set to retain a hollow three-dimensional form, but may be folded flat into a juxtaposed state by application of pressure.

Abstract: An endless flexible seamed belt with a mechanically and electrically invisible seam, substantially equivalent in performance to a seamless belt, is formed by joining two ends of substrate material, each end of which has a plurality of mutually mating elements in a puzle cut pattern which are in interlocking relationship. After the two ends are joined, an bonding is applied to the seam of the belt. When the belt is to be an electrostatographic imaging member, the electrostatics of the belt become very important. The two ends of a flexible substrate with a conductive coating applied thereto are interlocked and a conductive bonding is applied to the gap between the interlocking surfaces. The undercoating layer can then be applied to the adhered seam in order to smooth the seamed surface for application of the charge generating layer and the charge transfer layer. The undercoating layer may be relatively thicker than current undercoating layers to insure that the seam surface is smooth.
