    • A drawing device for handling a wide range of drawable thermoplastic resin materials including a first pressurizing tank and first buffer tank on an upstream side, and a second pressurizing tank and second buffer tank on a downstream side are disposed along a drawing tank having pressurized steam and a discharge unit connected to it. A medium supply and discharge may be connected to each of the first and second pressurizing tanks, and the first and second buffer tanks. Opening members may be disposed on respective upstream and downstream ports along the drawing tank. Small amounts of pressurizing medium may then be allowed to flow into the drawing tank through upstream and downstream ports. Next, material may be supplied from the upstream port into the drawing tank where pressurized steam may be introduced in airtight conditions, and then drawn to the downstream port, thereby producing a drawable thermoplastic resin material.
    • 一种用于处理各种可拉伸热塑性树脂材料的拉丝装置,其具有上游侧的第一加压槽和第一缓冲罐,以及下游侧的第二加压槽和第二缓冲罐,沿着具有加压蒸汽的拉伸槽, 与其连接的排出单元。 中等供给和排出可以连接到第一和第二加压罐以及第一和第二缓冲罐中的每一个。 打开构件可以沿着拉伸槽布置在相应的上游和下游端口上。 然后允许少量的加压介质通过上游和下游端口流入拉伸槽。 接下来,可以将材料从上游端口供给到可在气密条件下引入加压蒸汽的拉伸槽中,然后被吸入下游端口,由此制造可拉伸的热塑性树脂材料。
