<p>A flatbed applicator (1), for joining a first, thin, flat substrate and a second, flat substrate during a joining operation, comprising a table top (6), which exhibits a flat table surface (7) for supporting the substrates, two parallel, elongated guide and support means (13), and a traverse assembly (14), which is movable along the guide and support means and in the longitudinal direction (L) of the table top and which extends across the table top perpendicularly to said longitudinal direction (L) and comprises a squeezing means in the form of a squeeze roll (23), which extends across at least the major portion of the width (b) of the table top, said squeeze roll being vertically adjustable to enable it to be brought between a first, inactive position, where the squeeze roll clears and does not interact with the table top and/or said first and second substrates laid out on the table top, and a second, active position, where the squeeze roll interacts with the table top and/or said first and second substrates laid out on the table top, wherein the traverse assembly is adapted to be moved along the guide and support means during the joining operation with the squeezing means in the active position with said substrates between itself and the table top while the squeeze roll is caused to rotate about its axis and to exert a predetermined squeezing force upon the substrates. According to the invention, the flatbed applicator comprises heating means, which are adapted to bring the shell surface of the squeeze roll to a desired temperature or a desired temperature range during the joining operation, said desired temperature or desired temperature range exceeding the temperature of the air surrounding the squeeze roll.</p> |
