Abstract

The blowing-air bearing for tape comprises a porous hollow cylindrical member 10 which can be made of sintered powdered metal. Slotted surface air bearing 11 is made of thin metal and has a plurality of slots 13 formed through it. Bearing 11 is placed around member 10 and is supported by it.

Air Bearing for Web Lubrication

The blowing-air bearing for tape comprises a porous hollow cylindrical member 10 which can be made of sintered powdered metal. Slotted surface air bearing 11 is made of thin metal and has a plurality of slots 13 formed through it. Bearing 11 is placed around member 10 and is supported by it.

The configuration of 10 and 11 is supported by having one side of member 10 received in an annular groove in a member 15. The latter has an opening 16 communicating with a source of pressurized air. The opposite side of member 10 is received in an annular groove of cap 14 that is fastened to member 15 by screws 18 and 19. Member 11, received about member 10 is fastened about it with screws 17. Accordingly, the air passes through opening 16 into cavity 21, through the porous walls of member 10, and then through slots 13 to provide an air lubricated spacing between member 13 and tape 12 supported on it.

Using this technique, cylindrical member 10 can have a relatively rough surface and yet need not be machined. Member 11 can be made simply either from a stamping or by etching, having any burrs removed from its surface.
