请参见图 7。 本发明的钢筘为正斜齿段档式疏密异形钢筘 31， 该正斜齿段 档式疏密异形钢筘包括上筘梁 311和下筘梁 312、 筘片 313以及筘档 314。 筘片 313为多个， 分别倾斜或垂直固定在由上筘梁 31 1和下筘梁 312之间； 筘档 314 为两根， 位于筘片 313两侧， 分别固定在上筘梁! 311和下筘梁 312之间；
本发明正斜齿段档式疏密异形钢筘的筘片 313设为多个段档 3131， 每个段 档的筘片按上疏下密间距或下疏上密间距排列。 且每个段档的筘片中至少有 —根筘片 313a是垂直设置的。
本实施例正斜齿段档式疏密异形钢筘的筘片是由多个上疏下密间距或下 疏上密间距排列呈扇形的段档 3131组合而成， 其相邻两段档以顺逆相反互补 形式顺序排列， 即一个段档正扇形设置， 相邻的另一个段档呈倒扇形设置， 形成互补。 例如： 一个上疏下密间距排列的段档 3131a与下疏上密间距的段档 3131b交替排列。 采用该形式的钢筘配合使用在织机上织出的曲线织物如图 2 所示。
图 8描述了本发明中可采用的另一种正斜齿段档式疏密异形钢筘。 其中的 每组筘片段档 3131均从垂直的正齿筘片 313a开始排列， 并逐渐倾斜。 也可将 每组筘片第一个筘片垂直， 其余筘片按上疏下密或下疏上密逐渐散射排列。 采用该形式的钢筘配合使用在织机上织出的曲线织物如图 3所示。
本发明专用装置的工作原理是： 在织机工作时， 使本发明的正斜齿段档 式疏密异形钢筘在打纬时上下往复垂直 （相对于筘座） 运动， 因此经纱在处 于筘斜齿不同位置的约束而产生不同程度的经纱直斜线状态， 实现了经纱与 纬纱在被打入织口时的非垂直交叉， 使通过每一段档斜齿筘的经纱范围内织 造成纵向的曲线条。 织造时， 每个段档上下往复一次即形成一个完整的图 案。
本发明因正斜齿疏密异形钢筘规格 （筘号、 疏密比、 正斜齿比、 段档宽 度等） 的多样性及升降凸轮动程和变换齿轮的速比等工艺条件的配置的不 同， 曲线织物的形态会变化无穷。 工业应用性
采用本发明织造的织物其经纱全部或部分与纬纱呈非垂直交叉， 而且从 织物外观看， 布面经纱呈有序弯曲状态， 经纱排列形成互补性的疏密变化， 使布面产生明显或隐形的云纹图案， 具有优美的曲线形态。 可显著提高产品 的档次， 增加产品附加值和竞争力。
