Double Facer

Bonds the outer liners to make finished board.

SM-E double facer

What is a corrugated board line?

The double facer (double-backer) is the heated section that presses and bonds the liners to the corrugated web, then carries the board through a cooling/forming section to lie flat. The SM-E uses PLC-controlled hot plates and belt tension to suit any paper weight.

The SM-E runs at 200–250 m/min in widths of 1800–2500 mm. A PLC interface auto-switches the number of heating plates and the pressure to keep flute peaks intact across different paper weights. 18–22 hard-chromed hot plates (600 mm) with twin-cylinder S-type cotton-belt tensioning and auto belt-tracking.

FAQ

Common questions

What does a double facer do?

It bonds the outer liner(s) to the single-face corrugated web under heat and pressure, then cools and forms the board flat — producing finished 3, 5 or 7-ply board.

How does the SM-E handle different paper weights?

A PLC interface automatically switches the number of heating plates and the pressure to keep flute peaks intact across different paper grammages.
