1 Goss Urbanite Press Tension Control Upgrade

2 Goss Urbanite Press Upgrade Existing Unwind Stand Existing Unwind Stand: Top and bottom rolls were controlled by manual clamp brakes and dancers. The brake rotor was attached to the air shaft.

3 Goss Urbanite Press Upgrade Existing Unwind Stand Back side of the unwind stand with extended shaft journal Tension was controlled by a spring loaded dancer assembly

4 Goss Urbanite Press Upgrade Existing Unwind Stand Existing Unwind Stand: Manual control process Highly operator dependent Poor tension control High safety risk

5 Goss Urbanite Press Upgrade Closed Loop Tension Control Upgrade Tension Controller Upgrade Installed (2) S Series Tension Controllers, one dedicated to the top unwind stand and the other dedicated to the bottom unwind stand. Automated, precise, consistent control. Easy to install, set-up, and operate. S4 Tension Controller

6 Goss Urbanite Press Upgrade Closed Loop Tension Control Upgrade Load Cell Installation Load Cells replaced crude dancer control system providing precise, continuous, direct web tension measurement for automated control. Stainless steel body, semiconductor strain gauge, high quality, high performance. ES Dead Shaft-Idler Load Cells

7 Goss Urbanite Press Upgrade Closed Loop Tension Control Upgrade Tension Brake & Safety Chuck Upgrade High performance V Brake is installed along with new safety chucks replacing crude clamping brake, creating smooth linear torque from full roll to core while increasing safety and allowing for easier roll loading. MPC4 IP Converter & MAF3 Air Filter V Brake Safety Cover

8 Goss Urbanite Press Upgrade V Brake & Guardian Safety Chucks V Brake Features Easy Installation Wide Torque Range Linear Torque Output Increased Cooling Capacity High Thermal Capacity Discs Tool-less Maintenance High Heat Dissipation Bi Direction Operation Guardian Safety Chuck Features Redesigned Journal Seat with replaceable inserts Reversible Safety Lock Rotational Auto Locking Easier Roll Loading Increased Safety Factor Longer Service Life Built to Suit Shaft Ends Self Centering Journal Seat

9 Goss Urbanite Press Upgrade Closed Loop Tension Control Upgrade Easy to install mounting brackets used to mount new chucks to the machine frame Bracket Brake/chuck combination allows for axial adjustment. Axial adjustment is accomplished by turning the handwheel. New shafts are lighter and shorter

10 Goss Urbanite Press Upgrade Closed Loop Tension Control Upgrade For optimum performance, the spring tension of the existing dancer must remain at maximum.

11 Goss Urbanite Press Upgrade Closed Loop Tension Control Upgrade The unwind control system engineered and installed by Montalvo, insures a constant web tension entering the Tech-Energy Tech Express tower

12 Goss Urbanite Press Upgrade Press Upgrade Review BEFORE Upgrade: Manual control process Highly operator dependent Poor tension control High safety risk/dangerous Makeshift & cumbersome

13 Goss Urbanite Press Upgrade Press Upgrade Review AFTER Upgrade: Automated control process Easy to set-up & operate Consistent, precise tension control Safe & Reliable High quality, high performance, & versatile

14 Goss Urbanite Press Upgrade Montalvo Press Upgrade Advantages Consistent web tension allowing process to run all the way from full roll to the core. Automated tension control maintains the exact set tension throughout the process – Set It & Forget It On the fly axial web adjustment Tool-less, snap-out, snap-in brake pad changes – reduces and simplifies maintenance. Greatly improved operator safety Increased end product quality and overall productivity Reduced scrap
