Abstract
A pneumatic compliant tape guidance device for pneumatically applying a biasing load to a passing tape media. The tape guidance device includes at least one guide button and associated cylinder in which the guide button travels. It also includes a supply port which provides the input for a pressure and/or a vacuum to a pressurized chamber which couples the supply port with the cylinder. The guide button position and its applied pressure are controlled by a compressor which controls the amount of air pressure applied to the guide button through the supply port. The pneumatic compliant tape guidance applies pressure to the top edge or bottom edge of the tape media. The guide button may be configured to travel over a support tube which transfers the pressure/vacuum applied at the supply port to the guide button. The amount of pressure the guide button applies to the passing tape media is determined by the pressure/vacuum which is applied by a pneumatic source to the supply port. The pneumatic compliant tape guidance device enables the present invention to apply a predetermined pressure to the tape media, to change the amount of pressure quickly and easily, and can be used in multiple …
