    The invention relates to the field of reproduction technology, in particular, to the clamping of a format film photographic material to a plate by creating a vacuum. The aim of the invention is to simplify the design. In the device, the plate 3 is multi-layered and has a number of holes 4,5,6. The apertures 5 are valve chambers that are not closed by cinema material, the apertures 6 are automatically closed by freely movable valve plates 7, which are made of spring material and constitute a part of the surface of the cylinder. Due to this, the vacuum loss is minimal, since it is possible to clamp the film photo of any size. 2 hp f-ly, 4 ill.

    The invention relates to a device for fixing a format film photo material using a vacuum.
    The purpose of the invention is to simplify the design.
    Fig. 1 shows the proposed device, the cross section along with (:: a serving plate; Fig, 2 - a valve with a valve plate (valve Open); Fig. 3 - suction: cord with valve plates (pan closed); Fig. 4 - device 10, partial section along the cylinder with a vacuum clamp.

On the other side of the casing, an attachment plate 3 is installed, which is multi-layered fieHa with a plurality of openings 4,5,6 (Fig. I). The holes 3 made in the middle layer of the intake plate 3 are valve cylindrical chambers, in which there are freely Movable small valve plates 7, the latter are made of a very thin spring material: (usually from PRUSTER STEEL TAPE) and, predominantly (naturally, slightly arched 1 so that they represent a part of the cylindrical surface; In the valve chambers, plates 7 are mounted so that they press the side of the barrel: w; creating a vacuum, air flow entering hole 4 moves up the valve plates in all openings of the pressed sheet, where they are placed under the action of vacuum in front of the openings b and completely clog them, the air flow does not flow to the closed openings of the pressed pressure sheet. Vacuum can also act through openings 4 held sheet.
    After disconnecting the vacuum and the naked air into the casing, the spring pressure of the valve plates 7 ensures the release of the openings 6 leads them to their original condition
    When vacuum is turned on

    film photographs on the slab are quite small leaks (for example, due to the presence of burrs or surface roughness between the valve plates 7 and the holes 6), so that the vacuum can act through the holes 4 on the pressed object and fix it,
    When the I clamp is removed, it overlaps the line from the vacuum pump, and air is blown into the casing. The always small leaks between the valve plates 7 and the openings 6 provide for a quick pressure equalization in relatively small valve chambers, which is facilitated by the curvature of the valve plates.
    Valve elements in curved suction plates or cylinders also work with film clamping in drum-splitting machines (in FIG. 4 a part of such a cylinder; in the inner cavity of the cylinder, a vacuum can be created through the hollow axis of its support, and to release the film to carry out air injection),

    Invention Formula
    1, A vacuum clamping device for a format film photographic material comprising a base in the form of a casing, on one side of which a suction plate is mounted with an inner surface, with holes on the outer and inner surfaces filled with valve chambers, in each of which the valve plate of the spring material is made of, the diameter of the valve chambers is larger than the diameter of the holes on the surfaces of the pressing plate, and on the other side of the casing there is a channel It is designed with a vacuum pump, which is distinguished by the fact that, in order to simplify the design, each valve plate in the valve chamber is freely positioned as part of the cylinder surface of a disk mold, with a convex surface facing the hole in the outer surface of the accessory plate the axis of symmetry of the corresponding holes AND; the valve chamber connecting them.
