    (54) Plastic film bonding machine with adhesive spreading devices


    (57) The invention relates to a plastic film bonding machine in which solventless adhesive is used.
    The adhesive spreading devices comprise a pair of ground steel rollers (14,15) which effect an initial rolling of the adhesive, a rubber-covered roller (17) in contact with one of the said steel rollers and with a spreader roller (16), and pneumatic systems (18) designed to keep the rubber roller (17) pressed against the said rollers at a constant pressure whatever the roller rotation speed.
    The machine also includes a stop element (26) designed to limit the movements of the said rubber roller (17).
