TREATING METHOD AND APPARATUS FOR TREATING MEMBER PREPARED OF FOAM STYROL

摘要

PURPOSE:To reduce much more the vol. of foam styrol, by irradiation with far infrared ray to the treated materials consisting of boxes and cushionings prepd. of foam styrol and by pressing them thereafter. CONSTITUTION:The whole treating apparatus 2 is operated, and treated materials 4 are put on a conveyer belt 18 to be sent into an oven 26. As the treated materials 4 receive a far infrared ray irradiation of a specified level from each far infrared ray heater 8 for a specified time while being moved, such reactions as inducing the constituting molecules of the treated materials are induced and the vol. of the treated materials are gradually reduced to become smaller while exhausting included air gradually. They are sent out from an exit 26B and then successively and automatically fall on the second conveyer belt 34 and are transferred. The treated materials pass through a roll press mechanism 10 constituted of two stages while being still soft and are pressed and taken out after reduction to the state of the highest apparent density as remaining air is forcedly exhausted therefrom.
