ABSTRACT:
A machine for applying adhesive on one side of an elongate sheet material, and comprising an adhesive containing trough (19), an adhesive application roller (20) and a driven pressure roller (21). The sheet material (15) is being passed through the nip between said rollers and the width of the rollers surpasses the width of the sheet material. The contact surface of the pressure roller (21) upon the sheet (15), consists of an endless belt (23). The belt (23) runs via at least one guide roller (24) through a trough (25), containing rinsing fluid (25). In said trough the belt (23) runs past at least one further guide roller (27), and past a brush roller (29) which is mounted in the trough (25), adjacent the outer side of the endless belt loop (23). The brush roller is being driven in counter rotation to the direction of movement of the belt. The belt then runs back to the pressure roller (21), so that the section of the endless belt loop which has been driven past the rinsing fluid trough (25) and the brush roller (29), returns to the nip free from adhesive (22).
