    • Mutually overlying runs of two endless belts form therebetween a mold channel open at both ends. The mold forming runs move continuously in the same direction at the same rate of speed thereby to draw a sheet of material from a roll thereof downstream into and through the mold channel. The sheet material enters the mold channel in the form of a sleeve charged with only partially expanded granules of a synthetic thermoplastic material containing a heat expanding agent. As the charged sleeve moves downstream through the mold channel steam under pressure is introduced directly into the mold cavity thereby to fully expand the granules and covert the mass thereof into a coherent foamed agglutinated body which takes the shape of the mold cavity.
    • 在两个环形带之间形成相互重叠的行程,在两端形成开口的模具通道。 模具成型运行以相同的速度在相同的方向上连续移动,从而将一片材料从其下游向下拉入并穿过模具通道。 片材以仅装有包含热膨胀剂的合成热塑性材料的部分膨胀的颗粒的套筒的形式进入模具通道。 当带电套筒向下游流动通过模具通道时,压力下的蒸汽直接引入模具腔体中,从而使颗粒充分膨胀,并将其转化成呈模腔形状的粘结发泡凝集体。
