Abstract: The mechanism (1) for applying adhesive on wood panels/the like, comprises a carrier structure (2), a cartridge (4) for storing adhesive, a line that lies in connection with holes to take up adhesive from cartridge, a receiving tub and an adhesive dispensing device. The cartridge is provided with a bottom, side panels and a cover for the introduction of the adhesive through an opening. The bottom is provided with heating mediums for the adhesive and with holes for the removal of the adhesive. The heating mediums are attached at the bottom, the line and/or the tub. The adhesive dispensing device (17) acts for removing the adhesive from the tub and its application on the profile of a panel by a metering roller, which turns in contact with the profile of the panel. The cover is shiftable between a working position, at which it presses down the adhesive to the bottom over an actuator (10) under pressure, and a filling position, at which it is separated away from the opening, to ease the introduction of the adhesive. The side panels of the cartridge are provided with a band from a material with lower heat conductivity for heating the adhesive layer present at the proximity to the bottom. A temperature regulating agents are assigned to the first, second and third heating mediums. A capacitive sensor is used for reading the level of the adhesive in the tub. The line comprises three rigid and non-flexible aluminum sections, in which a horizontal section for the uptake of the adhesive from the holes, vertical section for the uptake of the adhesive from the horizontal section and for its elevation into the tub and an another section for the uptake of the adhesive from the vertical section and for its filling in the interior of the tub. The sections are separated and connected with one another by removable fastening elements. The vertical section of the line is provided with an upper end with an opening that is axially aligned and is lockable with a plug to facilitate the cleaning of the vertical section, and with a connection port that is laterally provided for the connection of the vertical section with that of another section. The adhesive dispensing device is connected with locomotive elements, which is provided with a shaft for transmission of the movement on the metering roller. The locomotive elements comprise an actuation shaft cover, which is connected with an engine and the transmission shaft over a universal joint. The carrier structure comprises a base, on which the cartridge, the line and the tub are attached, to which the adhesive dispensing device and the transmission shaft are connected, where the transmission shaft acts for the uptake of the movement of the universal joint by components that are stored and are arranged in an easily mechanically separatable manner. The transmission shaft exhibits a first pair of transversal taps at its lower end. The transversal taps are arranged diametrically opposite and provide for the transmission of the movement in the device to a corresponding second pair of taps, which extend themselves away from the universal joint.
