(57) The invention provides in a compact and mobile apparatus for applying a coating of
adhesive material (cementitious etc.) to the bonding surface of tiles, in particular
flooring tiles, at a desired tile laying location, whereby the tile coating operation
is carried out in a controlled and automatic manner.
The apparatus has a self-supporting frame, preferably equipped with rollers for moving
the same to a required flooring location, and assembled thereto it comprises the combination
of an adhesive holding tank (1) housing a dispenser roll (2) arranged in the semi-cylindrical
tank bottom, tile transfer means (F2) , tile stacking means (4) and driving incl.
power connection means. According to a key feature of the invention the actuation
of the adhesive roll applicator is established and controlled in selective synchronicity
with the displacement of the tiles resp. movement of the tile transfer means.
The tile transfer means and the dispenser roll are operatively connected in a suitable
manner and may be driven by hydraulic or electro-mechanical means. The selective actuation
thereof is advantageously controlled by contact switches or detector elements positioned
at suitable locations along the tile displacement path extending from the tile stack
magazine to underneath and past the dispenser roll untill a tile discharge position
at the end of the track. The tile transfer means may comprise a hydraulic piston unit
or an endless belt with driven rollers.
