AUTOMATIC · 1, 2 OR 3 COMPONENTS · PU, EPOXY · MEDIUM-LARGE PANELS · FIXED SPREADER
Automatic spreader for one, two or three component adhesives. Closely resembling the M5 but with a fixed spreader unit on a single frame.
How it works
The M4 services up to two press or lay-up tables placed after each other, each up to 20 meters long. The spreader unit is a frame rolling above the press table. The machine is designed to be easily integrated with existing press tables (delivery with new press tables is also possible).
A trolley on the spreader unit carries the adhesive spreader and moves it perpendicular to the table length. In the other direction the whole machine unit moves on the table track. The adhesive is applied through the spreader across the width of the panel.
Each adhesive component is pumped from a station at the side of the production line. The pumps are air-driven piston type, with mixing ratio metering by mechanically linked measuring cylinders.
Spreader options
Two alternatives — steel or plastic.
• Steel spreader — cleaned in a flush station after work, reused.
• Plastic spreader — disposable, thrown away after use.
For one-component adhesive systems, the spreader is automatically immersed and protected in an oil tray to prevent contact with the moisture in the surrounding air.
