ABSTRACT:
A straight length of tape (100) is confined in a cavity having a thickness and width essentially the same as the thickness and width of the tape (100). The cavity is defined by upper and lower opposing sets of thin flexible strips (24). In each set, strips (24) are positioned with their faces abutting each other and their inner side edges confronting the inner side edges of the strips (24) in the other set to define the thickness of the cavity therebetween. A series of longitudinally spaced clamps (28) press the strips (24) against the tape (100) to exert on the tape (100) pressure of sufficient magnitude and uniformity to prevent buckling and wrinkling of the tape (100). With the tape confined, a series of longitudinally spaced drive units (50) bend the strips (24) and tape (100) into a desired planform configuration. The tape (100) is held confined in this planform configuration until the tape (100) stabilizes in its new configuration.
