         9 . A method for supplying a cassette encased in a sleeve for a machine, the machine having an opening sized to accommodate cassettes having a first fixed dimension between first and second sides thereof and to accommodate sleeves containing the cassettes having a second fixed dimension between first and second sides thereof, the difference between the second and the first dimensions being substantially greater than twice the thickness of the sleeve, the method comprising the steps of: 
 providing the cassette with the first dimension between the first and second sides thereof;    providing the sleeve with the second dimension between the first and second sides thereof;    folding a first tab inwardly from the sleeve first side and a second tab inwardly from the sleeve second side to create a space equaling the first fixed dimension between the first tab and the second tab; and    containing the cassette within the sleeve between the first tab and the second tab.    
     
     
         10 . A method according to  claim 9  and further comprising the steps of folding a retaining member inwardly of the sleeve from a first edge thereof, and abutting a surface on the cassette with the retaining member to hold the cassette within the sleeve.  
     
     
         11 . A method according to  claim 9  wherein the first and second tabs are folded from adjacent a first end of the sleeve.  
     
     
         12 . A method according to  claim 9  further comprising the step of centering the cassette in the sleeve between the first and second sides of the sleeve.  
     
     
         13 . A method according to  claim 9  further comprising the step of folding at least one flap on the first tab inwardly toward the sleeve first side and folding at least one flap on the second tab inwardly toward the sleeve second side.
