摘要： The present invention is directed to a helical ribbon, and method and apparatus for making same. The helical ribbon is formed from a resilient ribbon having first and second surfaces and a length substantially longer than its width. A plurality of spaced-apart crimps extending across the width of the ribbon are formed in the first surface of said ribbon whereby said plurality of crimps cause the ribbon to curl back onto itself. The resilient ribbon used to form the helical coil of the invention must be sufficiently rigid to take and hold a crimp rather than merely bending, yet be pliable enough that the process of forming the crimp does not cause the ribbon to break. The invention also includes decorative items made from one or more of such helical ribbon(s).
摘要翻译：本发明涉及一种螺旋带，及其制造方法和装置。螺旋带由具有第一表面和第二表面的长度大大长于其宽度的弹性带形成。在所述色带的第一表面中形成延伸跨过色带宽度的多个间隔开的卷曲，由此所述多个卷曲使得色带卷曲回到自身上。用于形成本发明的螺旋线圈的弹性带必须具有足够的刚性以承受和保持卷曲而不仅仅是弯曲，而是足够柔软，使得形成卷曲的过程不会导致带破裂。本发明还包括由一个或多个这种螺旋带制成的装饰物品。
