3.2.3 Fabric Roll Assembly
The fabric roll assembly houses the fabric roll, the used fabric take-up roller, fabric drive motor and
fabric usage sensor.
The fabric roll is loaded onto the assembly, the fabric roll tube is pushed onto the sprung plunger
(left-hand end) then onto the brake actuator (right-hand). The fabric runs over the fabric sensor
spindle, turning the vane wheel through the fork opto sensor allowing the printer software to track
fabric usage, over the top of the plenum chamber and then threaded onto the used fabric take-up
roller.
The brake is pneumatically activated, the brake sections move outwards to grip the inner of the fab-
ric roll tube, preventing fabric slippage during cleaning sweeps.

3.2.4 Plenum Chamber and Interchangeable Inserts
The plenum chamber provides a surface for the fabric to press against when raised during a clean-
ing sweep, a solvent spray bar to "wet" the fabric with solvent and vacuum (via machine mounted
vacuum filtration unit [see 3.2.6 "Vacuum Filtration" [}18]) to aid with excess paste removal.
The plenum chamber has a removable insert section, with a choice of three differing tops (detailed
later in this section). All inserts are fitted with a connector for the solvent tubing.
The plenum chamber and associated inserts are available in the following widths:
