摘要:
Bei einer Formschaumanlage mit mehreren, auf einem drehbaren Tisch (1) angeordneten Formen (2) sind minde stens 2 Rechner (11, 12) vorgesehen Der erste Rechner (11) öffnet und schließt die einzelnen Formen (2) positionsabhän gig und heizt bzw. kühlt jede Form (2) zeitabhängig; der zweite Rechner (12) dient zur positionsabhängigen Steue rung der Einfüllvorrichtung (65).
摘要:
The system comprises a plurality of trays (7) in each of which the liquid mixture is poured, said liquid mixture characterizing the material the tiles are made of, that is resin. The casting apparatus generally comprises two tanks containing the components still in their liquid state, one for the resin (1) and one for the adhesion catalyst (4), a series of tubes (2) and (5), valves (14) and (16), pumps (13) and (21) and finally the two distributors (13) and (15). Said apparatuses for the automated handling of the trays are fitted into plants comprising several machines so that the resin tiles arranged in the containers (CTP) are ready for the subsequent packaging steps once the process (e.g. drying, decoration etc.) is over.
摘要:
Plant for obtaining sheets with optical effects, said sheets (2) receiving the impression of various patterns and/or illustrations (a, b, c, d and e) and receiving a layer of transparent resin (1); the engraving of the resin, by contact and polymerisation, produces the optical effects. In the plant, the application of the resin (1) to the sheet (2) is effected by rotogravure, rotary serigraphy, flexography, offset or other means, directly to the engraving cylinder (4, 4', 4'' or 4''') or on the sheet (2); ultra violet rays (18) are used as polymerising element, optatively with filter (19) for infrared rays, or an electron generator; the engraving and polymerization of the resin (1) are done at the same time and with the use of an engraver cylinder (4, 4', 4'' or 4''') without any seam. The printing means, the engraving means and the polymerization means form a compact assembly (20) arranged in line on a rotary machine (21).

摘要:
There is described a method of creating a hinge in a body of expandable material, said body being substantially flat and having at least two planar regions connected by said hinge to facilitate folding of the planar regions about said hinge, comprising: expanding said expandable material to form said body; creating a region of excess expandable material in said body adjacent said hinge; and compressing said region of excess expandable material into the hinge of said body after the expandable material has fused to create a hinge having a concentrated volume of expanded material when compared to said at least two planar regions of said body.
