40" Wide Sterling Co-Extrusion Sheet Line

Description

Used 40" wide Sterling co-extrusion sheet line. Reconditioned between 1998 and 2000 to produce films of synthetic paper 4–20 mil thick. The line consists of the following:

- 3.5" Sterling 30:1 L/D extruder driven by a 125 HP DC motor with Allen Bradley Series "B" SCR controller, 440 volt AC input. The extruder is electrically heated and water cooled, including a closed-loop water cooling system and side-vented (plugged) barrel. It features a 14:1 gearbox ratio.
- Maag melt pump currently mounted on the 3.5" extruder.
- 2.5" Sterling co-extruder, 30:1 L/D, with 13.351 gearbox reduction and 50 HP DC motor with SCR controller. It has an electrically heated, water-cooled barrel with a closed-loop water cooling system.
- 2.5" Entwhistle co-extruder, 30:1 L/D with non-vented barrel, driven by a 50 HP Reliance DC motor with SCR control.
Each of the above extruders is equipped with 3.5" MGB Engineering screen changers with oversized 3 HP hydraulic pumping systems for all three changers.
- Mann and Hummel 4-component resin volumetric dosing system for the 3.5" extruder and resin loaders for the 2.5" co-extruders, including vacuum pump.
- Co-extrusion feed block for the three extruders and a Cloeren 1200 mm (47") Epoch III flex lip sheet die with lip opening .000"–.050" and lip slot of 1120 mm (44").
- 40" wide Sterling hydraulically loaded chill roll stack including hydraulic pumping system. Downstack operation including temperature control package with heat exchangers and pumps and rubber pull roll assembly.
- NDC model 6100TC thickness gauging system with NDC model 103 sensor probe.
- Solo Systems two-sided corona treating station for 40" webs and Softal generator type 3009RV for up to 3.5 kW.
- 40" Egan single turret winder for 36" diameter rolls including dancer and lay-on roll.
- Rosenthal 48" sheeter, new in 2000, for sheeting 3–20 mil synthetic paper; includes two unwinders for rolls 36" diameter x 500 lbs each on 6" cores. The sheeter includes heavy-duty score cuts slitting for a maximum of four slits and runs at speeds of 23–24 metres per minute. It has a 36" long output conveyor. The sheeter is currently working inline.

Still installed and operational as used.
