摘要： The specification describes a shirred synthetic casing stick closed at one end by first extending an end portion of the shirred stick to form an unshirred end casing portion. The end casing portion is then twisted at a point to form an inner end casing section, and an outer end casing section separated by the twist. The outer end casing section is turned inside out (inverted) to cover at least a part of the inner end casing section and to thereby prevent untwisting. In a preferred embodiment, the end casing portion is twisted at a point indented, from the end of the extended casing portion, 1-2 times the diameter of the stick. The entire end casing portion is preferably inserted within the stick. In another embodiment, the stick is made of regenerated cellulose and an aperture is formed through the twisted closure portion. The specification also describes a method and apparatus for making such an end-closed, shirred synthetic casing stick.

摘要翻译： 本说明书描述了通过首先延伸旋转的棒的端部以形成未铰接的端部壳体部分，在一端封闭的开口的合成外壳棒。 然后将端部壳体部分在某一点处扭曲以形成内部端部壳体部分，以及通过扭曲分离的外部端部壳体部分。 外端壳体部分内翻（倒置）以覆盖内端壳体部分的至少一部分，从而防止退捻。 在优选实施例中，端部壳体部分在从延伸的壳体部分的端部缩进的点处被扭曲为棒的直径的1-2倍。 整个端部壳体部分优选地插入棒内。 在另一个实施例中，棒由再生纤维素制成，并且通过扭转的封闭部分形成孔。 本说明书还描述了一种用于制造这种封闭的，开口的合成套管棒的方法和装置。
