Features

• Fingerless type single facer machine
• Cardboard transmission is achieved by the method of vacuum suction, it equipped with high pressure air blower as well as a muffler, with adjustable of air blowing rate, to keep flute profiles stable under high speed.
• All the corrugated rolls, pressure roll, gluing roll are pneumatically controlled, and the air control unit and electrical control unit are concentrated in a cabinet.
• The main structure and frame are made of cast iron, up to the thickness of 200mm, equipped with independent gear box and cardan drive with submerged lubrication system to avoid noise and run stable.
• The shafts of corrugated and pressure roll are all heat resisting and lubricated by lubricating grease.
• The corrugated roll is made of 48CrMo alloy steel, with the treatment of hardening and tempering, grinding, laser-quenching, to reach the hardness of HRC60^o
• The pressure roll is made of medium carbon steel, with the treatment of hardening and tempering, grinding and chrome plated, the roll up and down is controlled by cylinder.
• The gluing roll is treated with grinding, mesh snicked and chrome plated on the surface, while the doctor roll has the same treatment.
• The gluing unit could be taken out integrally which is convenient for gluing roll maintenance and replacement. the gluing wall is sliding plate structure, pneumatic control glue supplying, the glue quantity is digital displayed.
• The gluing unit is available to run independently or non-independently. 
• The pre-heater is made of seamless steel tube, and connected by flexible metal hose.
