    • An apparatus comprising a movable frame reciprocatingly movable longitudinally of a tubular knitted fabric, a fixed press bed member spaced apart from the frame in the direction of transport of the fabric, at least one pair of upper and lower fabric feed rollers mounted on the frame and stoppably drivable in the transport direction, a tenter core member reciprocatingly movable with the frame for tentering the fabric as fitted therearound and having one end held by the feed rollers and the other end extending toward the press bed member, and a holding member for releasably pressing the fabric as tentered by the core member against the press bed member. The holding member is provided on the fabric facing side thereof with the cutter blade of a press cutter and elastic pieces. The cutter blade cuts the fabric as held to the press bed member by the elastic pieces after the tenter core member is retracted with the feed rollers driven in the transport direction to prevent the fabric from being stretched by the retraction.
    • 一种装置,其特征在于,包括:可动框架,其可以纵向往复移动地连接在一个管状针织物上;固定的压床构件,沿着所述织物的输送方向与所述框架间隔开;至少一对上下织物进给辊,安装在所述框架上; 在运送方向上可移动地移动的拉幅机芯件,与框架往复移动的拉幅机芯件,用于将织物卷绕在其周围,并将一端保持在进给辊上,另一端延伸朝向压床部件;以及保持部件,用于可释放地按压 所述织物由所述芯部件折叠抵靠所述压床构件。 保持构件在其与织物相对的侧面上设置有切割刀和弹性片的切割刀。 切割刀片在拉幅机芯件在传送方向上被驱动的进给辊缩回之后,通过弹性片将织物切割成保持在压床构件上,以防止织物被收缩拉伸。
