摘要:
UV curable material is metered onto a casting drum and is partially cured anaerobically adjacent the surface of the drum. The film is applied to a substrate with the uncured portion thereagainst and a post radiation cure is effected to fully cure and adhere the coating onto the substrate. In other embodiments the substrate may be molten or the coating may be fully cured and applied to the substrate by means of a UV curable adhesive compatible with the coating and the substrate.

A method of making an open-ended, reinforced, layered belt is disclosed. The method includes extruding a top layer onto said cords and meterering it into a first cavity or into a first gap defined by a smooth cylindrical mandrel and a molding band or a first gap defined between said mandrel and a laminating roller, thereby forming a carcass comprising said cords embedded at one surface of a film of said top layer material and training said carcass on a second portion of a cylindrical mandrel, said second portion including a second cavity defined between said cylindrical mandrel and a molding band or a second gap defined between said cylindrical mandrel and a laminating roller.

The present invention provides an optical sheet (300e) having a plurality of light guide plates patterns, each light guide plate pattern having a micro-patterned output surface for emitting light, and a micro-patterned bottom surface opposing to the output surface. The optical sheet is made in steps comprising: extruding a resin (450a) into the nip between a first patterned roller (480a) and a second patterned roller (480b) at a first patterned roller surface temperature T1, a second patterned roller temperature T2, and a nip pressure P1, to form the optical sheet, the optical sheet having a first patterned surface and a second patterned surface, the first patterned surface having a micro-pattern transferred from the first patterned roller and the second patterned surface having a micro-pattern transferred from the second patterned roller.

Embodiments refer generally to systems and methods for manufacturing a cylindrical spar tube (120) of the sort that might be used in a horizontal stabilizer (108) for a helicopter (100). An exemplary method may comprise laying out onto a flat surface (220, 420) (and possibly stacking) plies (201, 202, 203, 301, 302, 303, P001-P004) of composite material, rolling the material (424, 624, 852) onto a mandrel while applying pressure and curing the rolled material.
摘要:
A method of manufacturing a conveyor belt having an elongate body made of uncured rubber and/or synthetic rubber. A polymeric parting material is placed adjacent to the upper and lower surfaces of the body, and heated platens are applied to the upper and lower surfaces of the body (i.e. belt material) to soften the adjacent upper and lower layer portions of the belt. This causes the softened belt material to flow into interstitial openings in the parting material. The resulting belt has the parting material squeezed into a thinner layer and embedded in the adjacent surface portions of the body of the belt. This provides a substantially uniform and reflectively soft texture surface.
