2. Functional Scope and System Components

The overview presents the complete production line in conjunction with the quadruplex extruder, including material conveying systems, belt guidance, belt scanning, acceleration zones, cross-cutting, and cassette winding stations.

2.1 Main Assemblies
- Extruder head
- Multiple "swings" (pivoting arms), numbered 0 to 13
- Strip scanning systems ("Scan 1", "Tri Scan", Strip detection 1–4)
- Cross-cutting unit ("cross-cutter")
- Cutting machine
- "Cutting table"
- Conveyor belts labeled BELT 1, BELT 2, BELT 3

Winding Section:
- Cassette winders 1–4
- Winding stations labeled "Winder 1–4"
Note: Winders 1 and 2 marked "out of service"
- Cooling water tank
- Cooler
- Electrical peripheral equipment, TCU units (temperature control units), control cabinets ("control cabinet", "ctrl.cab.")
- Steel platform structures ("platform", cooling section platform)

3. Operating Parameters

3.1 Production Speed
0–30 m/min (specified production speed range)

3.2 Acceleration Section (Acceleration Speed Q1)
From the provided calculations:
- Basic production speed: 30 m/min = 0.5 m/s
- Rocker cycle time: 4 sec
- Belt shifting cycle time: 4 sec
- Gap length: 2 m
- Acceleration length: 8 m
- Acceleration time: 16 sec
- Speed difference: 2 m/s = 7.5 m/min
- Resulting acceleration speed: 37.5 m/min
