(54) DEVICE FOR WALLPAPER STICKERS

one

The invention relates to the construction industry, namely to devices for pasting the surface of walls with both.

A device for gluing wallpaper is known, comprising a spring-loaded pressure roller fixed between handles, a bobbin for a roll of wallpaper fixed on brackets, and a reservoir I mounted under the bobbin I.

A disadvantage of the known device is the great laboriousness of the work, since the movement of the device along the wall is done manually.

A device for wallpaper sticker is known, its height-adjustable rod and the frame fixed on it with the clamping element 2.

The disadvantages of the known device are that with its help it is difficult to glue the wallpaper along the entire height of the wall, since the bar only tells the frame vertical movements, as well as the fact that the necessary quality of glue and wallpaper is not provided.

The purpose of the invention is to mechanize the process of gluing wallpaper and improving the quality of gluing.

The goal is achieved by the fact that the device for gluing wallpaper, including a height-adjustable rod and a frame fixed to it with a clamping element, is equipped with a movable platform on which the rod is hinged, and the clamping element is rigidly attached to the frame of the pneumatic chamber, the latter in a flat closed vessel with a wall thickness increasing from the center of the vessel to the periphery.

FIG. 1 shows a wallpaper glueing device; in fig. 2 - oasoid AA in FIG. one.

The device has a platform. 1 on four wheels 2, moving along the wall 3 at a certain distance along the rails 4. Platform 1 is connected by a hinge 5 of the supporting rod 6, on which two movable brackets 7 are attached, to one of them a latch bar 8 (in plan work on the principle of scissors). The ends of the staples 7 are movable in the horizontal direction in the guides 9 of the plate 10 of the device, to which the pneumatic chamber 11 of plasticized polymeric material is rigidly attached, with pipe 12 to the compressor or receiver, which increases from the center of the periphery. A roll of wallpaper 13 is fixed on an axis 14, rigidly attached to the lower jaw of the upper clip 15, by known methods, through which the panel 16 is passed and then fixed by the lower clip 17. The movable stop 18 serves to fix the device in the working position, lifting it is done with a lever with a lock 19 . The upper and lower clips are attached to the rod 6.

The device works as follows.

The prepared roll of wallpaper 13 is mounted on the axis 14, the end is passed between the jaws of the upper clip 15, unwinds to the required length over the pneumatic chamber 11 of the plate 10, which is installed in a horizontal position and rests on the brackets 7 and the hinge 5 connecting the rod 6 to the platform 1. End The web 16 is secured with the lower jaw 17, the web is tensioned by turning the roll 13 in the opposite direction and secured with the upper jaw 15. A layer of glue is applied using one of the known methods. The upper end of the pole 6 is lifted and secured in the working position, the stopper is fixed to the ceiling by a movable stop 18, set in motion by the lever 19, followed by its fixation in the required position. By pressing the movable brackets 7, the device plate 10 approaches the surface of the wall 3, and this creates a preliminary pressure on the area of the panel 16. The movable brackets 7 are fixed in a predetermined position with a retainer. By applying pressure through conduit 12 to pneumatic chamber 11, the final gluing of the wallpaper panels is carried out. The pressure is transferred from the vertical center line of the sheet to the edges due to the thickness difference between the walls of the pneumatic chamber, which allows creating an overpressure along the central vertical at the moment of time followed by pressure distribution to the edges, squeezing air and excess glue. Then the panel is trimmed, the next panel is glued after moving the platform 1 along the guides 4, repeating the previous cycle, combining the pattern, while doing this on the device on the device in a horizontal position.

The use of the proposed device allows to mechanize the process of pasting wallpaper, improve the quality of gluing and minimize the use of manual labor.
