ABSTRACT:
A single facer corrugating machine for improving the gluing effect of the medium paper and the liner includes an elastic press plate for supplying a suitable pressure on the medium paper and the liner after the former is coated with glue on one side, a pressure chamber and a heating plate for providing a suitable pressure and prolonged heating to the glued sheet of medium paper and liner to make them more firmly glued together. The pressure chamber and the heating plate are disposed downstream of the lower corrugating roll and the primary preheating roll in a direction of travel of the glued sheet of medium paper liner. The pressure chamber is filled with a suitable pressure so that the medium paper and liner are more firmly glued together when they are fed between the pressure chamber and the heating plate and are subjected to suitable pressure and heating.
