Abstract
The single facer includes a load-bearing frame for housing a first corrugating roller and a second corrugating roller, meshing with each other and mounted in the load-bearing frame. The single facer further includes a pivoting structure, pivoted to the load-bearing frame about a pivoting axis and including two pivoting arms supporting two guide rollers of a continuous flexible member. Two actuators raise and lower the pivoting arms and the guide rollers. A hinge system allows to keep the pivoting structure cantilevered to replace the continuous flexible member.
