There is disclosed a cutting mechanism (22) for severing elongate fibre reinforcement material (14) in composite material lay-up equipment (10), the cutting mechanism (22) comprising a cutting element (60) and a counteracting element (76) which cooperate to sever fibre reinforcement material (14) extending through the nip between them, the cutting element (60) being mounted on an elongate arm (44) which is pivotable about a pivot axis A spaced from the nip, to displace the cutting element (60) relatively to the counteracting element (76) to perform a cutting stroke, the mechanism (22) further comprising guide means (52) arranged to guide the fibre reinforcement material (14) through the nip in a feed direction transverse to the pivot axis A, and an actuation device (84) for driving the elongate arm (44) in a cutting stroke, the actuation device (84) acting on the elongate arm (44) at a position away from the cutting element (60). There is also provided composite material lay-up equipment (10) comprising the cutting mechanism (22).

La invención consiste en un procedimiento para la fabricación de un guarnecido para vehículo automóvil de forma que la lámina de espuma termoplástica que forma el núcleo central del guarnecido, está formada a partir de la mezcla de material termoplástico, aditivos y fibra de refuerzo, donde la fibra de refuerzo forma parte integra de la lámina de espuma termoplástica.
摘要:
A hollow filter tube (12) is produced with a longitudinal seam (14) and a fixed diameter. In the formation of the hollow tube (12), glue is applied along a longitudinal side edge portion of an endless strip (16), and the strip (16) is then formed into a tubular shape (46) with an unglued longitudinal edge portion tucked directly under and against the glued side edge portion. The hollow tube (46) is then heated to drive moisture from the glue and size and shape the hollow tube (46). Ultimately the formed hollow tube (46) is cut into specific lengths (12).
摘要:
A method (10) of manufacturing absorbent articles (60) in which first and second stabilizing strips (32, 34) confer stability during the manufacturing process by controlling the position of side panels (38, 40, 96, 98) with respect to absorbent structures (28). In the thus manufactured articles, material of the stabilizing strips (32, 34) remain on the side panels to provide a region of material having consistent properties.

Disclosed is a process for producing composite board, and the said board is glass fiber reinforced magnesium cement board with wood grain. The process comprises two steps of preparing a mold with wood grain and preparing glass fiber reinforced magnesium cement board using the mold. The first step comprises forming film bearing wood grain, copying the wood grain onto mill rolls, and rolling the formwork with the mill rolls. The second step comprises steps of preparing MgCl2 solution, agitating the mixed raw materials to obtain slurry, conveying the molds, scratching the slurry, disposing the raw materials, rolling, separating, shelving, curing, impregnating the board into water to remove free MgCl2, cutting, spraying protecting-paint, and so on. The process can produce the board with three-dimensional appeal, wood grain similar to that of log, and beautiful appearance. The board produced by the process has advantages of fire proof, water proof, vermin proof, light weight, compression and bending resistant, high strength, no moss growing, and so on.
摘要:
L'invention concerne un profilé complexe (1) constitué d'un profilé métallique (2) enrobé d'un feuillard métallique (3). Elle se caractérise en ce que le feuillard (3) a une dureté superficielle supérieure au profilé (2), et que le feuillard (3) adhère au profilé (2) en tout point d'une de ses faces. Elle concerne encore un procédé d'enrobage de profilés (2) consistant, à les acheminer les uns derrière les autres, à leur appliquer successivement, après conformage, une bande continue (5) d'un matériau (3) en vue de son collage sur chaque profilé, pour l'enrober, caractérisé en ce qu'on achemine ces profilés (2) avec un espacement entre eux, qu'après adhésion on repère les extrémités respectivement aval (6A) et amont (7B) de deux profilés successifs (2A, 2B), et qu'on y procède à deux opérations de coupe distinctes, selon leur espacement.
