Abstract

A master processing apparatus for use with a pair of removable feed rolls comprises a frame, a master processing assembly, and a gauge assembly. The removable feed rolls carry a supply of stock material to be unwound, at least one of the stock materials having a layer of adhesive provided thereon. The frame removably mounts the feed rolls. The master processing assembly performs a master processing operation wherein the master processing assembly causes adhesive bonding between a master and the stock materials. The gauge assembly has (a) a supply roll monitor operable to continuously monitor an amount of stock material remaining on the feed rolls and (b) a user readable supply level indicator operatively connected to the supply roll monitor. The supply level indicator is operable to continuously indicate to the user the amount of stock material remaining on the feed rolls as the stock materials are being unwound.

Claims

1. A master processing apparatus for use with a pair of removable feed rolls, the removable feed rolls carrying a supply of stock material to be unwound, at least one of the stock materials having a layer of adhesive provided thereon, said apparatus comprising:

2. A master processing apparatus according to claim 1, wherein said supply level indicator comprises a pointing arm.

3. A master processing apparatus according to claim 2, wherein said supply roll monitor comprises a cam element rotatably mounted to said frame and providing a cam surface at one end thereof and a stock material engaging surface at an other end thereof,

4. A master processing apparatus according to claim 3, further comprising a biasing arm connected to said pointing arm, said biasing arm configured and positioned to bias said pointing arm into continuous engagement with said cam surface of said cam element such that said engaging surface of said cam element is biased into continuous engagement with the stock material of one of the feed rolls.

5. A master processing apparatus according to claim 4, wherein said biasing arm and said pointing arm are integrally formed of an elastically deformable material.

6. A master processing apparatus according to claim 2, wherein said supply roll monitor comprises a stock material engaging surface and a resilient arm member,

7. A master processing apparatus according to claim 2, wherein said pointing arm is enclosed within said frame and wherein said frame includes a transparent portion, said pointing arm being visible through said transparent portion.

8. A master processing apparatus according to claim 7, wherein said transparent portion includes measurement indicia thereon, the pointing arm moving relative to the transparent portion and hence the measurement indicia thereon during the master processing operation to provide the indication of the amount of stock material remaining on the feed rolls.

9. A master processing apparatus according to claim 2, wherein said frame includes an opening such that a portion of said pointing arm extends through said opening and is visible to the user.

10. A master processing apparatus according to claim 9, wherein said frame includes measurement indicia thereon, the pointing arm moving relative to the frame and hence the measurement indicia thereon during the master processing operation to provide the indication of the amount of stock material remaining on the feed rolls.

11. A master processing apparatus according to claim 1, wherein said master processing assembly comprises a pair of cooperating nip rollers constructed and arranged to apply pressure to the master and the stock materials during said master processing operation.

12. A master processing apparatus according to claim 1, further comprising an actuator constructed and arranged to affect operation of said master processing assembly.

13. A master processing apparatus according to claim 1, wherein said supply roll monitor is continuously engaged with the stock material of one of said feed rolls so as to continuously monitor the amount of stock material remaining on said feed rolls.

14. A master processing system comprising:

15. A master processing system according to claim 14, wherein said supply level indicator comprises a pointing arm.

16. A master processing system according to claim 15, wherein said supply roll monitor comprises a cam element rotatably mounted to said frame and providing a cam surface at one end thereof and a stock material engaging surface at an other end thereof,

17. A master processing system according to claim 16, further comprising a biasing arm connected to said pointing arm, said biasing arm configured and positioned to bias said pointing arm into continuous engagement with said cam surface of said cam element such that said engaging surface of said cam element is biased into continuous engagement with the stock material of one of the feed rolls.

18. A master processing system according to claim 17, wherein said biasing arm and said pointing arm are integrally formed of an elastically deformable material.
