1. A dual web conveyance system comprising:
a first unwind unit configured to unspool a first web from a first spool; a first rewind unit configured to spool the first web around a second spool; a second unwind unit configured to unspool a second web from a third spool; a second rewind unit configured to spool the second web around a fourth spool; a control system comprising:
a first drive control unit configured to control a first unspooling speed of the first unwind unit,a first tension control unit configured to control a first spooling tension of the first rewind unit,a second drive control unit configured to control a second unspooling speed of the second unwind unit, anda second tension control unit configured to control a second spooling tension of the second rewind unit, wherein the control system controls the first unspooling speed of the first unwind unit and the first spooling tension of the first rewind unit to convey the first web at a first predetermined speed and at a first predetermined tension, and wherein the control system controls the second unspooling speed of the second unwind unit and the second spooling tension of the second rewind unit to convey the second web at a second predetermined speed and at a second predetermined tension. |
