(54) DEVICE FOR APPLYING LIQUID COMPOSITIONS TO LONG DIMENSIONAL MATERIAL

one

The invention relates to devices for applying liquid formulations with intermittent lines to lengthy material, such as fiberglass, and can be used in the manufacture of panels for construction, aircraft construction and shipbuilding.

A device for applying adhesive strips of predetermined thickness and width to a lengthy material, such as a foil, comprising a housing, a system of shafts, a reservoir for adhesive compositions and a glue applicator is known. In the known device, the glue applicator is made in the form of a rotary drum composed of two hollow cylinders, inner and outer, with which there are feed holes, opening and closing of which occurs by moving the inner cylinder relative to the outer one. Moreover, the adjustment of the width and thickness of all adhesive strips is simultaneously carried out by rotating the applicator around the longitudinal axis, thereby changing the gap of the gap between the foil and the applicating groove 1.

However, the known device does not allow changing the parameters of the pads of the applied areas in separate strips.

The closest to the invention in its technical essence and the achieved result is a device for applying liquid compositions to a long material containing a guide roller, a material feeding mechanism, a drive

In the known device, the reservoir for the compositions is made in the form of a cylinder mounted above the guide roller with the possibility of moving in the radial and axial direction relative to the roller, and the dispensers are made in the form of hollow tubes; screw-connected with tips, in the lower part of which there are spring-loaded balls, interacting with the fabric when

20 release glue of them. The width of the adhesive strip on the fabric is adjusted by changing the size of the outlet. When moving upward, the tank tears off the tips of the tubes from the glass cloth and shifts them by a size equal to the displacement of the adhesive strips on the fiberglass 2. A disadvantage of the known device is the limited range of its application due to the inability of the device to change the step of the applied areas relative to others in adjacent bands. The purpose of the invention is to expand the range of application of the device. The goal is achieved by the fact that in a device for applying liquid compositions to a long material containing a guide roller, a material feed mechanism, a drive mechanism, a tank for compositions with metering devices, the guide roller is equipped with a drive and contacting through long-length material with dispensers cams installed with the possibility of moving along and around the axis of the roller and fixing in a predetermined position. FIG. 1 shows schematically a device for applying liquid formulations, a general view; in fig. 2 shows a possible application of the compositions on a long material; in fig. 3 is a longitudinal section of the guide roller with cams; in fig. 4 is a section A-A in FIG. 3; in fig. 5 is a section BB in FIG. 3. The device comprises a drive guide roller 1, a material feed mechanism 2, including an unwinding unit 4, a drive mechanism 5, and a reservoir for formulations 6 with metering devices 7. The guide roller 1 is provided with removable cams 8 contacting through metering materials to it by means of screws 9 and adapted to move along and around the axis of the roller. The guide roller 1 is connected to the drive mechanism 5 by means of an asterisk 10 and a chain transmission 11. The number of dispensers 7 is set in accordance with the number of continuously applied strips. In so doing, the dispensers are connected to the reservoir 6 by flexible pipes 12, for example, with hoses. The device works as follows. The lengthy material 3, for example fiberglass, is wound from the unwinding unit 4 and pulled by the material feeding drive mechanism 2 between the glass fiber guide roller 1 and the dispensers 7 into which the composition comes from the reservoir 6. At the same time, the glass fiber is applied to where the cams 8 are in contact through glass fiber with dispensers 7. Applying the compositions with a certain schag across the width and length of the material is provided by moving the removable cams 8 along the diameter of the roller 2 and along its axis and fixing them on the roller with screws 9. Dispensers 7 are moved by flexible pipes 12 and are installed directly above the cams to interact with them. The number of applied areas of the composition along the strips depends on the number of cams in the same row, and the change in pitch between them is achieved by setting different number of cams on the guide roller or changing the distance between them around the roller circumference, as well as changing the outer diameter of the cams. The length of the applied area of the composition along the strips can be changed by increasing the length of the outer lip of the cam from the minimum size to the full outer diameter of the circle of the cam lip. The offset of the cams at a certain angle in adjacent rows enables the production of deposited areas displaced by a certain dimension along the length of the material. The variation of the schaga between discretely applied strips across the width of the material is carried out by moving the cams along the axis of the guide roller, and the distance between them can be both the same and different. The application of the invention allows to significantly expand the range of application of the device by introducing an adjustment of the distance between the applied strips both in length and width of the material. In this case, the length of the applied plots is also regulated and the possibility of displacing the applied plots in adjacent strips relative to each other is provided for. Claims of the invention A device for applying liquid compositions to a lengthy material comprising a guide roller, a material feed mechanism, a drive mechanism, a tank for compositions with metering devices, characterized in that, in order to extend the range of application of the device, the guide roller is driven and contacting through a long material with metering cams mounted for movement along and around the axis of the roller and fixing in a predetermined position.
