Abstract
The present invention relates to an apparatus for adhering a soft slab and a covering material together. The apparatus for adhering the soft slab and the covering material together includes: a moving unit consisting of a plurality of rollers for moving the soft slab; a conveyor unit including a belt configured such that air passes through the top and bottom surface thereof, and a driving unit for driving the belt, the conveyor unit being intended for transferring a covering material seated on the top surface of the belt toward an adhesive surface of the soft slab; and an air suction unit provided at the bottom surface of the belt so as to suction air such that the covering material is tightly attached onto the top surface of the belt, thereby attaching the covering material onto the adhesive surface of the soft slab without generating pleats.
