Random Access Loop Machine

Any belt, such as 10, is accessed from any one of a plurality of storage pockets 12 in a honeycomb mechanism 21. The latter is vertically movable in a direction D relative to processing chamber 22.

For example, belt 10 is shown after having been moved into processing chamber 22. This has blowing air lubrication on both sides from ports formed through walls 11 and 18 of chamber 22. The ports receive pressurized air P. Belt 10 is driven rotationally in chamber 22 by capstan belt 13 which is rotated about rollers 14 and 15 when vacuum V is applied to chamber 16. Belt 13 is perforated throughout. Thus, a vacuum pressure V in chamber 16 passes through the perforations in belt 13 and sucks belt 10 against belt 13 to drive belt
10. On the other hand, when belt 10 is being accessed to or from pocket 12, blowing air at pressure P is provided to chamber 16 to disengage belt 10 from belt 13.

Read-write head 17 engages the outer moving magnetic surface of belt 10 to read or write information on it. A rotating capstan belt similar to belt 13 can be provided along or substituted for either wall 11 or 18 or both for engaging belt 10 to rotate it in a fixed position.
