    • An elongated knit web is flattened and guided by an apparatus having a support frame which extends longitudinally in a plane and which has an upstream and a downstream end. A pivot supports this frame for pivoting about a pivot axis transverse to the plane at the upstream end. A pair of transversely extending and longitudinally spaced spreader rollers are provided on the frame adjacent the upstream end and each has a pair of screwthread formations of opposite hand, these spreader rollers being driven to spread out the web transversely. A pair of transversely extending and longitudinally spaced guide rollers are provided on the frame between the spreader rollers and the downstream end, these guide rollers being freely rotating and having surfaces which are made to adhere to the web to prevent its edges from curling up. A control system pivots the frame about its pivot axis to position the edges of the exiting web.
    • 细长的针织网被平坦化并由具有在平面中纵向延伸并且具有上游和下游端的支撑框架的装置引导。 枢轴支撑该框架以围绕在上游端处的平面横向的枢转轴线枢转。 一对横向延伸且纵向间隔开的扩张辊设在靠近上游端的框架上,并且每个具有相对的一对螺纹结构,这些扩张辊被驱动以横向扩展腹板。 一对横向延伸且纵向隔开的导向辊设置在扩展辊和下游端之间的框架上,这些导辊自由旋转并具有粘附到卷筒纸上以防止其边缘卷曲的表面。 控制系统围绕其枢转轴线枢转框架以定位出口网的边缘。
