Profile veneering

More difficult is veneering of profile surfaces - bent and curved. In manufacture of furniture for zapressovki apply the special adaptations named sulagami. In one case it is massive wooden kolodki or metal forms of a corresponding profile, the return to a profile faneruemoj surfaces. They are suitable for veneering of the same products of an identical profile. In other case tsulagi can be used for zapressovki details of a various profile - these are so-called loose, reechnye and pneumatic tsulagi. The last represent rubber chambers in which in process zapressovki air is forced under pressure, or, on the contrary, is extorted for vacuum creation.

Are Most simple in manufacturing reechnye and loose sulagi. Reechnye sulagi is a little thin reek, pasted on a fabric in parallel each other with small intervals, loose - a bag from the strong fabric, half filled with hot sand. The width and length tsulag depend on the sizes faneruemyh products.

Sulagi with sand press to a profile surface longitudinal bruskami and clamps, and reechnye - cross-section profile bruskami. Between them and plywood stack a rubber lining. Clamps sulagi press gradually, since one party to provide a tension of a fabric and uniform pressure on faneruemuju a surface. At an arrangement of decorative plywood fibres along it for the prevention of ruptures it is possible to paste over from a face sheet with several cross-section paper tapes. For fine details instead of sulag it is possible to take advantage of a piece of thick rubber.

In all cases preliminary warming up of profile preparations ° is obligatory till 50-60.

Recently ways of veneering without zapressovki, on the basis of new glutinous structures, in particular glue PVA became known. The thin layer of this glue put on stuck together surfaces dry within several minutes before formation of a transparent film, then on a product impose plywood sheet, cover with a paper and iron a hot iron. .

This way is good for interline interval gluing. As to decorative plywood by thickness to 0,5 mm, and also porous, the hot way is necessary for checking up preliminary to be convinced that glue does not get through a time on a surface. This council concerns and other synthetic glues.
