ABSTRACT:
Tape guiding methods and apparatus advance a tape through an arcuate bend having equal radii at both edges. Within that bend an unbalance providing a net force transversely of the tape is created at the tape edges while maintaining the equal radii. The advancing tape is guided by applying it with the created net force to a reference surface while maintaining the equal radii.
