Description of Fingerless Single Facer

The primary utility of this fingerless single facer machine is to perform the high-precision corrugation and adhesive bonding of linerboard and medium into a continuous single-faced web. By employing a fingerless architecture, the system eliminates traditional mechanical guiding obstacles, allowing for superior flute formation and higher production velocities. It serves as the high-performance "wet end" heart of the corrugation line, ensuring that the resulting corrugated structure possesses the uniform geometry and structural integrity required for subsequent multi-ply assembly.

Machine Features

Advanced Metallurgy & Durability: The upper and lower corrugating rolls are engineered from premium 52CrMo alloy steel, undergoing sophisticated heat treatment and surface precision-grinding to achieve an exceptional hardness rating of HRC 58-60. This ensures longevity even under the most demanding production conditions.

Precision Adhesive Management: This fingerless single facer machine utilizes a high-performance, circulatory gluing system. The glue applicator roll features a laser-carved reticulate surface plated with hard chrome for perfect adhesive transfer, and the unit allows for both manual and motorized width adjustments to match varied paper sizes precisely. Furthermore, the gluing unit operates independently during machine stops, preventing adhesive drying and buildup.

Pneumatic & Mechanical Control: Pressure and positioning for the primary corrugating, pressure, and glue rollers are governed by highly responsive pneumatic systems. Mechanical power is supplied via a cardan drive-isolating the power source from the machine body to dampen vibrations-while the reduction gearbox utilizes an oil-immersed lubrication circuit for whisper-quiet performance.

Vacuum-Stabilized Corrugation: To maintain flawless flute profiles at extreme speeds, the unit incorporates a vacuum-absorption cardboard guide assembly. Equipped with integrated air-flow regulation, this system guarantees that the medium remains locked onto the corrugating roll throughout the entire forming process.

Integrated Maintenance Features: Every critical component of this fingerless single facer machine is designed for sustainability. High-temperature resistant synthetic grease is utilized for the primary bearings, ensuring reliable, long-term operation in high-heat environments.
