摘要：
A stretching apparatus of fibre tows in a pressurized steam environment includes an elongated stretching chamber having a generally rectangular section of a low height, within which the tows are treated with saturated or overheated steam at high temperature and pressure and simultaneously undergo a mechanical stretching operation. The stretching chamber has a width sufficient to house multiple tows mutually flanked in a running plane and is formed within a stretching chest made of aluminum. The stretching chest is housed in a supporting structure, having a higher structural rigidity than the stretching chest, which includes a plurality of contact elements apt to determine a predefined position of the stretching chest with respect to a direction perpendicular to the tow running plane and to allow a limited mobility of the stretching chest in the other two mutually perpendicular directions which lie in the plane, length and width respectively.
摘要（中）：
在加压蒸汽环境中的纤维丝束的拉伸装置包括具有低高度的大致矩形截面的细长拉伸室，其中在高温和高压下用饱和或过热蒸汽处理丝束，同时进行机械拉伸操作。 拉伸室具有足够的宽度以容纳在行进平面中相互侧面的多个丝束并且形成在由铝制成的拉伸胸部内。 拉伸胸部容纳在支撑结构中，具有比拉伸胸部更高的结构刚度，其包括多个接触元件，所述多个接触元件倾向于确定拉伸胸部相对于与丝束运行平面垂直的方向的预定位置，并且 允许拉伸胸部在分别在平面，长度和宽度上的另外两个相互垂直的方向上的移动性有限。
