摘要： An embossed plastic film is made ultra soft and cloth-like by providing a plurality of post-embossed stretched areas along lines that are spaced uniformly across its width and length. The stretched areas are thinner than the unstretched areas. Films also have unique textures and offer cloth-like or non-woven appearances.

摘要： A combination window shade and clutch assembly is provided to prevent over-tensioning of the spring motor of the window shade. The clutch assembly includes spool means connected to one end of the spring motor and cup means, both movable along the window shade dowel, and each having locking means formed to engage one another. The cup means engages retaining means formed in the rotatable housing of the window shade so that rotation of the housing is transmitted to the spool means through the cup means while their locking means are in engagement. The locking means of the cup means and spool means are operable to maintain engagement to permit tensioning of the spring motor a predetermined number of turns of the cup means and spool means together with window shade housing, and then disengage to prevent further tensioning of the spring motor without restricting rotation of the housing in such one direction.
摘要翻译：提供组合窗帘和离合器组件以防止窗帘的弹簧电动机的过度张紧。离合器组件包括连接到弹簧马达和杯装置的一端的线轴装置，两者均可沿着窗帘销移动，并且每个具有形成为彼此接合的锁定装置。杯子装置接合形成在窗帘的可旋转壳体中的保持装置，使得壳体的旋转在其锁定装置接合时通过杯装置传递到卷轴装置。杯装置和卷轴装置的锁定装置可操作以保持接合以允许弹簧马达与窗口罩壳体一起预定数量的杯装置和卷轴装置的匝数，然后脱开以防止弹簧的进一步张紧电动机，而不限制壳体在这样的一个方向上的旋转。
