the hydraulic press. Table frame is made of rectangular tube, rubber rollers and side rollers to guide
the moving of panels. The shafts are interconnected and chain motivated by the geared motor.
Technical sepcification:
• The working surface of the table assembly: 6.2 x 1.25 meters.
• Table height: 0.7 meters.
• The velocity of the panel on the table to 20 meters per minute.
• Weight: 550 lbs.
The operation steps on the table to assemble panels:
1. Laying one piece of OSB board on the table.
2. Gluing the polyurethane adhesive on the surface of OSB board.
3. Laying one piece of EPS block on the OSB board.
4. Gluing the polyurethane adhesive on the surface of EPS block.
5. Laying another piece of OSB board on the glued EPS block.
6. Rolling the OSB+EPS+OSB panel into the hydraulic press.
