    • Sleeves formed of fabrics comprised wholly or in part from engineered plastic materials which are settable by heat to be biased to a specific sleeve geometry are disclosed. One form of sleeve illustrated involves heat-setting plastic material to a helical configuration by wrapping an elongated strip of the fabric material helically on a mandrel, heating the material while in the helical configuration, and thereafter cooling the material so that is has a permanent helical set with the side edges of the material in overlapping relation. the sleeves so formed may be collapsed into a short cylinder for packaging. In use, the compressed cylinder is allowed to expand lengthwise over an elongate object or objects to effect a jacketing of the same without additional assembly effort. A second form of sleeve disclosed involves setting the fabric material in tubular form, wherein the product is formed to have side edges abutting one another or in overlapping relation. A product so formed snap fits over an elongated substrate without the need for other attaching means. Sleeve products may have a circular, rectangular, square or triangular cross-section or various combinations of these cross-sections.
    • 公开了由织物构成的套筒,其全部或部分由工程塑料材料组成,其可通过加热而被固定以偏压到特定的套管几何形状。 所示的一种形式的套筒包括将塑料材料热成型为螺旋结构,通过将细长的织物材料条螺旋地缠绕在心轴上,以螺旋形状加热材料,然后冷却材料使其具有永久螺旋 以与重叠关系的材料的侧边缘设置。 如此形成的套筒可以折叠成短圆筒以进行包装。 在使用中,允许压缩圆筒在细长的物体或物体上纵向地扩展,以实现其外套,而无需额外的组装工作。 公开的第二种类型的套筒包括将织物材料设置成管状,其中,产品形成为具有彼此邻接或相互重叠的侧边缘。 如此形成的产品卡扣配合在细长基材上,而不需要其它连接装置。 套筒产品可以具有圆形,矩形,正方形或三角形的横截面或这些横截面的各种组合。
