Patent ID: 7104304

Claim:
A master processing apparatus comprising: a frame having an upwardly facing opening; a first feed roll rotatably mounted within the frame and carrying a supply of a first supply substrate; a second feed roll rotatably mounted within the frame and carrying a supply of a second supply substrate; a layer of pressure-sensitive adhesive disposed on at least one of the supply substrates; the first and second feed rolls being removable through the upwardly facing opening of the frame to enable replacement thereof through the upwardly facing opening; an upper cooperating pressure applying structure and a lower cooperating pressure applying structure, the cooperating pressure applying structures being positioned adjacent one another for receiving the first and second supply substrates therebetween and having surfaces engageable with the supply substrates to apply pressure thereto; and a cover mounted in a closed position to the frame to cover the upwardly facing opening, the cover cooperating with the frame in the closed position to urge the upper cooperating structure downwardly against the lower cooperating structure so as to apply the pressure to the supply substrates; the cover being movable to an open position to uncover the upwardly facing opening to provide for separation of the upper cooperating structure from the lower cooperating structure, and to enable the first and second feed rolls to be removed and replaced through the upwardly facing opening of the frame.
