The calenders 20 are also heated up with the valve 13 in such a way that such a quantity of air that is necessary for the uniform inflation of the web before its entrance to the cylindrical section 9 of the conical ripper 7. Turn on the cold air blower. At the same time, all mechanisms for transporting the web are included. Air passes through receivers 12 and collector 1 1 and through nozzles 4 enters the annular chamber 10. Due to the reactions of annular air jets emerging from nozzles 4, in the area between them, i.e. in the annular chamber 10, an overpressure occurs and an annular airbag is formed. This creates a lift force acting on the surface of the spreader 7, pushing it out and holding it in a vertical floating state. Between the walls of the spreader 7 and the body of the support unit 1, a gap of 6-10 mm is formed, ensuring the first pass of the web to spread 7 and transporting it along the spread 14. The pressure drops in the annular chamber 10 and the rate of air outflow from the nozzles 4 are selected in such a way that the air, creating lift and pushing out the spreader 7, rises tangentially to the surface of the latter and carries the web along with it, moving it to the spreader 14 (in Fig. 2, the arrows show the distribution of air flow in the annular chamber 10). By adjusting the airflows, the feed rate of the web to the spreader 14 can be varied to match the web removal rate with the transport rollers 18, which makes it possible to obtain the desired technological shrinkage. Hot air coming out of the ducts 23 perpendicular to the movement of the web is forced through it, passes through the internal section of the equalizer 14 and enters the suction path of the fans 22. The web, dried to residual moisture, goes to the converter 1.6, where it is folded in half and fed to the calenders 20 through the transporting rollers and the device for controlling the width 19. During the calendering, the web is finally dried and rolled into a roll.
