Master processing apparatus

A master processing apparatus to be used in conjunction with a feed roll carrier and first and second feed rolls held together on said carrier, said first and second feed rolls carrying respective supplies of first and second stock materials at least one of which has a layer of adhesive disposed thereon, said apparatus comprising:

• a frame constructed and arranged to enable said feed roll carrier to removably mount said first and second feed rolls together to said frame for unwinding of said first and second stock materials;
• a master processing assembly positioned with respect to said frame such that, when said first and second feed rolls are mounted to said frame, the master can be fed into said master processing assembly with said first and second 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 processing assembly causes adhesive bonding between the first and second stock materials and the master being fed therein and then subsequently discharges the processed master and stock materials.

A feed roll assembly for use in conjunction with a master processing apparatus, said apparatus comprising a frame and a master processing assembly constructed and arranged to perform a master processing operation wherein said processing assembly causes adhesive bonding between substrates fed therein, said feed roll assembly comprising:

• a feed roll carrier;
• first and second feed rolls carried on said carrier, said first and second feed rolls carrying respective supplies of first and second stock materials at least one of which has a layer of adhesive disposed thereon;
• said feed roll carrier holding said feed rolls together to enable said first and second feed rolls to be removably mounted together to said frame for unwinding and feeding of said stock materials into said master processing assembly such that, when said feed rolls are removably mounted to said frame, the master can be inserted into the master processing assembly of the apparatus with said first and second stock materials unwound from their respective feed rolls and disposed on opposing sides of the master, thereby enabling the master processing assembly to perform the aforesaid master processing operation wherein said processing assembly causes adhesive bonding between the first and second stock materials and the master being fed therein and then subsequently discharges the processed master and stock materials.
