Abstract
An improved single-faced corrugated cardboard sheet making machine is provided, in which at the time of sticking a core paper web and a liner to each other in a single-facer equipped corrugating machine, impacts and vibrations are not generated, and hence troubles such as breaking of paper webs do not occur. The improvement resides in that the known single-faced corrugated cardboard sheet making machine having a pair of corrugating rolls for corrugating a core paper web into a wave shape and a pasting member for applying paste to corrugation crest portions of the corrugated core paper web, is further provided with an endless belt for pressing and sticking a liner to the core paper web applied with paste. The pressing condition of the endless belt can be adjusted, and a device for cleaning the surface of the endless belt is also provided.
