Description

(54) EKETRUSION GLUTED FOJiOBKA FOR ijOJlHBA

FILM FILMS

An e-shouting of o-p-shitsits to the technique of applying photosensitive emulsions on the basis of Kushsfotoplex with the use of ankleepk extrusion heads.

Known for the use of the slit head ™ for watering cistoppenicus, holding the plates, thus forming the output sheeps and the connected channels, divided by longitudinal partitions into several cavities II.

The disadvantage of the known device is the impossibility of haluchsil polrytg with alternating light sensitive composition and gelatin.

most advantageous in terms of receiving and supplying liquid.

The inserts shown in FIG. 1, have a cylindrical shape of both the outer and the inner surface. On the outer walls of the inserts grooves 15 and 16 are made, and on the edges - grooves 17 and 18, located respectively against the slots 15 and 16.

The grooves 15 and 16 are arranged in chess order relative to each other (FIGS. 2 and 3) and, together with the walls of the distribution channels 6 and 7, form the slots 4 and 5, which are separated from each other by means of 19 and 20 and are connected by slots 17 and 18 9 to 10 cavities. In the upper part of distribution channels, grooves 17 and output in slots 4 and 5.

To ensure an equal thickness of the layers extending from the slots in the slit, the depth of the slots is uepi along the entire length of the head; as they move away from shtutserov13 and 14.

The extrusion slotted head can have distribution channels with cylindrical walls (Fig. 5) and with walls of a rectilinear profile (Fig. 6), where there is one insert 21 and a partition 22, which presses the insert against the walls of the distribution channel. In the free state, the insert 21 has a greater bending angle than the angle between the walls of the distribution channel. When assembled as a result of elastic deformation, a tight seal appears.

The extrusion slit head proposed works as follows.

A photosensitive emulsion is supplied to the cavity 9 through the fitting 13, and to the cavity 10 through the fitting 14 - a solution of gelatin. The emulsion passes through the grooves 17 and 15, and the gelatin solution through the grooves 18 and 16.

In the slots 15 and 16, thin layers of the aforementioned liquids are formed, and then the layers are transferred to slots 4 and 5 (Fig. 1 and 3), where they are combined into a system consisting of alternating emulsion strips and gelatins (Fig. 4),

Claims (1)

Invention Formula An extrusion slit head for watering film films containing plates that form exit slots and distribution channels connected to them, separated by longitudinal partitions into several thicknesses, characterized in that with the provision of alternating strips of photosensitive emulsions and a neutral plastic substance, it provides inserts adjacent to the stacks of distribution channels and filled with grooves located on the side of the channel walls in a staggered order It is also different and communicating the cavities of the distribution channels with the output slots of the head. ij Patent of Germany No. 12О8998, cl. 57c5, 1956 S. iS V, l. .
