ABSTRACT:
A bonding mechanism of corrugated paper making machine includes an endless loop-like band and an adjusting mechanism for adjusting position and configuration of the band with respect to a surface sheet of the corrugated paper pasted on a core sheet. The adjustment performed by the adjusting mechanism changes an area of surface contact between the band and the surface sheet of the corrugated paper and thus changing a pressurizing area between the surface sheet and the core sheet. The surface contact between the band and the surface sheet enhances bonding operation of the surface sheet to the core sheet and increases the time when a pressure is applied in the pressurizing area to bond the surface sheet and the core sheet together. The surface contact eliminates the potential damage to the surface sheet caused by application of concentrated force at a single contact point on the surface sheet and increases the manufacturing efficiency of the corrugated paper.
