摘要:
A plurality of bedposts (20) is connected to a perimetric bedframe (2) by one or more extruded section members (6) each fastened at its ends and by appropriate fastening means (9), to the longitudinal members (3) of the frame. Each section member (6) having an inverted-U shape in section exhibits, at the lower part thereof, a pair of main wings (17) from which two opposite wings (18) extend and define a main T-shaped guide groove (16) housing the head (24a) of one or more threaded connecting rods (24) for fastening of respective bedposts (20). Formed in a vertically disposed end portion (8) of the section member (6) is a grooved seating (27) arranged to receive a drawer (28) or other similar accessories to be associated with the bedframe (2). A second grooved seating (32) is located at the upper part of the section member (6) and is designed to rotatably engage a pivot element (34) carried by an adjustable reclining head of the bed (33) or other accessories.
摘要:
Process and plant (1) for continuously manufacturing prodcts of latex foam comprising recesses, as mattresses and the like. A plurality of recesses or cells are molded on the layer of latex laid and moved forward, said recesses comprising a base open on the laying surface and being subsequently cross-linked by introducing steam under pressure into the cavity formed during the molding step through the base of the cell. The plant comprises a conveyor element (2) in which a plurality of plates (25) placed side by side are provided with protuberances (26) corresponding to the cells to be formed in a latex layer. The protuberances are open at the base for introducing steam into the inner space.

摘要:
Process and plant for manufacturing cellular products, of latex foam or the like, wherein the latex foam is injected on a surface (8) moving forward between two stations (9, 10) and a plurality of cells is moulded from up downwards and in direction perpendicular to the faces of the layer. Subsequently, the vulcanizing step is carried out by supplying heat around the layer and through the cells. The plant comprises means (14) for moulding the cells and driving means for moulding the cells perpendicularly to the faces of the layer moved forward in a continuous or intermittent manner.
摘要:
A process and a plant (1) are described for manufacture of latex foam products comprising recesses, such as mattresses (2), cushions and the like. The plant makes use of a plurality of carriers (9) placed in a ring-like configuration limited by a first, upper stretch (10) between a foam injecting station (3) and a product-removing station (5) and by a second lower stretch (11) for the return of the carriers devoid of foam, to the injecting station. At any moment the first stretch (10) is filled with carriers (9), touching each other and making a single mold on which foam is injected, while on the second stretch, at least one carrier, or a discrete number of carriers, considerably separated from one another, travel. The carriers (9) of the first and second stretch (10,11) are moved by different and independent operating systems and the speed of the carriers of the second stretch is considerably higher than the one of the carriers of the first stretch, so that, whatever the adopted solution, a carrier (9) can be always present at the injecting station (3), while another carrier leaves the removing station (5).
