Residual distortion during embossing can be easily removed by passing it through a leveler, and it will not be twisted or twisted. ■ Embossing lines and loops are provided to allow smooth connections between lines. ■ Cut to a standard length, cut out the box folded part, cut to a standard length, and divide into n equal parts in the width direction.
Since it is formed using multiple series of rolls, a wide variety of surface materials can be formed. ■Easy to fold boxes.

The box-folded portion of the 0-box-folded standard length body is sealed with a sealant to form a continuous band, so that the synthetic resin foam can be continuously discharged. ■Most of the inside of the mold is sealed except for the exhaust gas outlet and the entrance/exit of the composite plate, which improves heat retention and reduces the leakage of harmful gases and combustion gases into the working environment, greatly improving worker safety and hygiene. It can be improved. ■The timing of contact between the backing material and the mixture can be easily and freely selected by varying the position of the guide roller, so the backing material can be reliably bonded and the strength of the composite plate can be greatly improved. ■
Yields are high because the embossing line, cutting, and combined box-folding line are controlled via a control panel.
