A device for cooling an extruded tubular film to a stream of liquid refrigerant is known, comprising two annular manifolds mounted in the course of the tubular film movement for supplying and collecting coolant.

The purpose of the invention is to enable the film to be cooled when it is extruded upwards.

In the device according to the invention, the collector for collecting the coolant is provided with an annular sealing skirt with through perforations. A part of perforations adjacent to the collector is connected to the air suction line. The lower part of the sealing skirt is equipped with a bell, under which an annular bath is installed to collect cooling water flowing from the bell. The bath has an annular nozzle for supplying compressed air into the gap between the mouth of the skirt and the film sleeve.

FIG. 1 shows the proposed device; in fig. 2 - collector for collecting coolant, incision; in fig. 3 - internal surface of the sealing skirt, scan.

A device for cooling an extruded tubular film with a stream of liquid refrigerant contains two annular manifolds 2 and 3 installed along the tubular film 1 for feeding and collecting coolant. A coolant collector 3 is provided with an annular sealing skirt 4 with through perforations 5, a part of which, adjacent to the collector 3, is connected to the vacuum suction chamber 6, which is connected to the vacuum pump 9 through a water separator 8. the surface of the sealing skirt is provided with a wetting area

5 grooves 10 (see Fig. 3) in which lubricant is supplied and the excess flows along the walls of the socket 11 of the sealing skirt into an annular bath 12 provided with rings 13 mi con) 0 scrap 13 for supplying compressed air to the gap between the socket 11 skirts and film sleeves to blow fluid from it.

The process of cooling the film in the pre) 5 lagged device is carried out as follows.

The film sleeve emerging from the die 14 (Fig. 1) of the extruder 15 is blown with air through an annular duct

20 16 and enters the collector 3 to collect the coolant, then passes through the collector 2 for the supply of coolant, where a thin flowing layer of coolant is formed. The folding device 17 is transformed into a flat shape and is fed by the thin rollers 18 to the winding device 19. Liquid refrigerant 20 is fed through pipe 21 to

3Q ring collector 2, from where a thin layer 22 flows down the walls of the sleeve from the film to the collector 3 to collect coolant with a vacuum space and collects in the accumulator 23 with the drain pipe 24 (see Fig. 2)

35

The refrigerant penetrates the plastic section of the sleeve and the extruder head by preventing the film from sucking the walls of the seal of the skirt with perforations interfacing with

40 camera vacuum suction. In this case, film shaking is provided.
