PURPOSE:To fold accurately a corrugated board sheet along its ruled line while preventing the sheet from being crushed. CONSTITUTION:Cylindrical support members 16, 16 are arranged in parallel at a given interval. More than one holes 16a are bored in the upper surface of the support member 16 at given intervals in the longitudinal direction. On the upper surface of the support member 16, a guide 18 is installed in the longitudinal direction. A channel 18a connected with the hole 16a is formed on the guide 18. An endless belt 20 set on rollers which are installed on the outside of both longitudinal end parts of the support member 16 slides on the guide 18 when the belt leaves and runs inside the support member when it returns. More than one holes 20a are bored in the endless belt 20 at given intervals in the running direction. A suction blower 26 is connected to the support member 16. A corrugated board sheet 10 is transferred stably while being stuck on the surface of the endless belt 20. |
