Creating Transverse Curvature With Air Jets Of Varying Sizes

This is a pneumatic arrangement for imparting columnar strength to a section of thin recording tape to prevent buckling when it is desired to feed tape rather than draw it.

Two small tubes 1 and 2 are mounted in parallel on either side of the path to be traversed by tape 3. Small orifices of varying diameter are drilled along the opposed surfaces of the tubes. The orifices vary in diameter from smallest to largest outwardly from the midpoint of tube 1 and from largest to smallest in tube
2.

Air is supplied to both tubes. The resultant pattern of air flow from the opposed orifices causes the section of tape 3 to curve. The curvature provides the column strength needed to prevent buckling, when the tape section is pushed from one position to another.
