Single Facer Machine: Complete Technical and Buying Guide

The single facer machine is the most critical component of any corrugating line. It determines production speed, board quality, and overall efficiency.

What is a Single Facer Machine?

A single facer forms flat paper into corrugated flutes and bonds a liner sheet to one side.

How it Works

1. Medium paper feeds from roll stand through preheaters

2. Paper passes between corrugating rolls to form flutes

3. Adhesive applied to flute tips

4. Liner bonds to flute tips with heat and pressure

5. Single-face web exits to bridge conveyor
