Abstract: This invention comprises apparatus and methods for folding and crimping shredded strips of sheet material into preselected lengths of interlocking, decorative material and/or bulk packaging material. The apparatus generally includes an attachment for a commercial paper shredding device which shreds sheet material therein. The apparatus comprises a movable barrier against which the shredded strips of sheet material are impelled upon being expelled from cutting blades of the shredding device. The movable barrier causes the strips to become controllably jammed within a confined area between the barrier and the cutting blades. Further insertion of additional strips into the confined area causes the strips to become compacted, folded, and crimped against a remaining dam of jammed sheet material located within the confined area. This causes the strips to fold and press against themselves, and form lengths of thin sheet material having an accordion-shaped configuration.

A multiplicity of radial yarns are sequentially woven in the axial and radial directions about various circumferential yarn layers. A solid member is also provided which has a group of axially extending yarn strings secured thereto. The axially extending yarn strings include strings that constitute a portion of at least one of the core and the warp yarns. When the disclosed three-dimensional fabric is used in a composite, it is unnecessary to subject the composite to mechanical processing to attach a coupling part.

Abstract: A lightweight, compliant, high strength fabric providing controlled stretch, and a process for its manufacture. The fabric is consolidated into a unitary structure from a single stacked-film matrix of one or more thin elastomeric films, each having at least one reinforcing fiber embedded in the film in a sandwich construction. The reinforcing fibers are buckled along their length when the film is in a relaxed state, and if more than one fiber, arranged in a generally parallel relationship with each other within each elastomeric film. The stacked elastomeric films are cross-plied such that the courses of fibers in the separate films are aligned in selected multiple directions, with each course of fibers lying in its own plane. Stretching of the fabric in any of the selected multiple directions is uninhibited by the buckled fibers but is limited when the fibers reach a straightened condition. As the fabric stretches, the fibers straighten, eventually limiting the stretch of the fabric as the fibers become taut.

Thus the weight of the resin mold clutch facing has been reduced, and its friction and anti-wear properties have been improved.
