Description

The invention relates to devices for the manufacture of roll roofing materials and can be used in the building materials industry, as well as in the textile and other industries associated with the manufacture of multilayer roll materials.

A device for coating rolled roofing materials is known, comprising a bath for coating mass, a guide roller mounted on a lifting mechanism, a pulling roller, slats mounted above the bath and means for calibrating the thickness of the coating 1.

However, the quality of manufacture of roofing material is not high enough, which is explained by its air-saturation in the area of the entrance to the rolls. The combination of a roller and a calibrating device in the device leads to an intensive trapping of air bubbles during calibration, which further reduce the life of the roofing felt.

The aim of the invention is to improve the quality of the material.

The goal is achieved by the fact that, in a device for coating a coiled material, including a bath for coating mass, a guide roller mounted on a lifting mechanism, draws the best roller, crossbeams mounted above the bath, and means for calibrating the thickness of the coating, means for calibrating made in the form of two mirrored rows of plates, the lower parts have the shape of a socket, and the upper ones are located in the area of the material's exit to the pulling roller, and the plates are fixed on the crossbars.

FIG. 1 is a diagram of the device; in fig. 2 shows section A-A in FIG. one; in fig. 3 is a view B in FIG. one; in fig. 4 shows a section B-B in FIG. 3

The device includes a bath 1 for a cover mass in which a guide roller 2 is installed, a pull roller 3 and calibration means made of two mirrored rows of plates, each of which is fixed on crossbars 4 and 5. The plates 6 are made of spring material and form between

the gap G, which is the temperature compensator of their linear expansion when heated from the molten mass, is fixed with squares 7 with screws 8 and 9 to the crossbars 4 and 5, respectively.

The lower parts of the plates D form a bell and are placed in the coating mass in the bath. The axis 10 of the guide roller on the brackets 11 and the crossbar 4 with one row of plates fixed to it is attached to the lifting mechanism 12. In the working position, the crossbar 4 ends 13 are mounted on grooved supports 14 and can be moved with the help of a screw mechanism 15 roller 2 on the brackets relative to the crossbar 5, which establishes the calibration gap between the rows of plates.

The crossbar 5 with the row of plates is attached to the bath with bolts 16.

The device works as follows.

The lifting mechanism 12 of the crossbar 4 by the ends 13 is led out of the groove-shaped supports 14 and lifted along with a number of plates 6 fixed on this crossbar by a guide roller 2 on the brackets 11 to a position at which the base of the web material passes freely to the pulling roller 3. Then lifting These elements are lowered to their original position. When the substrate is moved onto the roller 2 in the socket between the rows of plates 6, the covering mass is intensively applied to the substrate, while in the socket it is not possible to come into contact with air. The presence of gaps between the plates and the restriction on the width of the plate sizes excludes their distortion. The substrate with the applied layer after exiting the calibration gap between the rows of plates is moved by a pull roller 3 for cooling.

The technical and economic effect of the introduction of the device is conditioned by the improvement of its quality, which contributes to the extension of the service life of the roofing carpet to 15-20 years.
