8FT Fully Automatic Putty Spreading Line

8FT Fully Automatic Putty Spreading Line
The 8FT Fully Automatic Putty Spreading Line is a high-efficiency and intelligent production system designed for uniform putty (filler) application on plywood surfaces. It is widely used in modern plywood manufacturing lines to improve surface smoothness, enhance bonding quality, and increase the final product grade.

This automatic putty spreading line integrates feeding, conveying, putty coating, leveling, and stacking, ensuring consistent thickness control and reducing manual labor. It is especially suitable for large-scale plywood factories seeking high output, precision coating, and stable performance.

8FT Fully Automatic Putty Spreading Line

1. Product Description


The 8FT fully automatic putty spreading line adopts advanced coating technology and intelligent control systems to achieve precise and even putty application on plywood panels.

The system typically consists of:

  • Automatic infeed conveyor system
  • Putty spreading machine (roller or scraper type)
  • Thickness control and leveling system
  • Drying or transfer section (optional)
  • Automatic stacking system

The machine uses high-quality rollers or blades to evenly distribute putty across the plywood surface, filling gaps, cracks, and pores. The PLC control system allows operators to adjust coating thickness, speed, and pressure according to production requirements.

With its 8-foot working width, the line is ideal for standard plywood panel processing, ensuring high compatibility with existing production lines.
