    • A method for infusing gas into a thermoplastic material includes positioning a sheet of a thermoplastic material into a vertical or substantially vertical position; positioning a sheet of a gas-permeable material into a vertical or substantially vertical position; and winding together the positioned sheet of thermoplastic material sheet and the positioned sheet of gas-permeable material to form a roll of the thermoplastic material interleaved with the gas-permeable material, the interleaved roll having a longitudinal axis oriented in a vertical or substantially vertical position. The method also includes exposing the interleaved roll to an atmosphere of a gas pressurized to infuse the thermoplastic material with the gas, while the longitudinal axis of the interleaved roll is oriented in a vertical or substantially vertical position; and then unwinding the gas-infused interleaved roll, while the longitudinal axis of the interleaved roll remains in a vertical or substantially vertical position.
    • 将气体输入到热塑性材料中的方法包括将热塑性材料的片材定位成垂直或基本垂直的位置; 将透气材料片放置在垂直或基本垂直的位置; 并且将定位的热塑性材料片和所定位的透气材料片组合在一起,以形成与气体可渗透材料交错的热塑性材料卷,所述交错辊具有纵向或垂直位置的纵向轴线 。 该方法还包括将插入的辊暴露于加压的气体的气氛中,以使气体进入热塑性材料,同时交替的辊的纵向轴线被定向在垂直或基本垂直的位置; 然后展开气体输入的交错辊,同时交错辊的纵向轴线保持垂直或基本垂直的位置。
