Gauge assembly for a master processing apparatus

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:

• a frame constructed and arranged to removably mount the feed rolls;
• a master processing assembly constructed and arranged such that, when the feed rolls are removably mounted to said frame, a master can be inserted into said master processing assembly together with the stock materials unwound from their respective feed rolls and disposed on opposing sides of the master;
• said master processing assembly being constructed and arranged to perform a master processing operation wherein said master processing assembly causes adhesive bonding between the master and the stock materials being fed into the feed side thereof and subsequently discharges the processed master and stock materials outwardly from a discharge side thereof;
• and
• a gauge assembly having (a) a supply roll monitor operable to continuously monitor an amount of stock material remaining on said feed rolls and (b) a user readable supply level indicator operatively connected to said supply roll monitor, said supply level indicator being operable to continuously provide a visual indication to a user of the amount of stock material remaining on the feed rolls as the stock materials are being unwound so as to enable the user viewing the supply level indicator to visually verify the amount of stock material remaining in the feed rolls.
