Corrugating Line Factory Layout and Installation: Complete Planning Guide

Proper factory layout and installation planning can save months of time and significant cost when setting up a new corrugating line. This guide covers the essential requirements for a successful installation.

Phase 1: Site Selection and Building Requirements

Building Dimensions:

Minimum clear height: 8-10 meters (for roll handling and maintenance access)

Floor space by line type:

• 3-ply line (100-200 m/min): 60m × 15m minimum

• 5-ply line (150-250 m/min): 80m × 18m minimum

• High-speed line (250-350 m/min): 100m × 20m minimum

• Add 30-50% for paper storage, finished goods, and utilities

Floor Requirements:

• Reinforced concrete, minimum 200mm thickness

• Load capacity: 5-10 tons/m² under machine sections

• Level tolerance: ±3mm over 10 meters

• Isolation joints between machine foundations and general floor

Environmental Conditions:

• Temperature: 15-35°C for consistent paper behavior

• Humidity: 50-65% RH (critical for paper and adhesive performance)

• Dust control: Adequate ventilation and filtration

• Lighting: 300-500 lux at operating level

Phase 2: Utility Requirements

Electrical Power:

• 3-ply line: 200-400 kW total connected load

• 5-ply line: 400-800 kW

• High-speed line: 600-1200 kW

• Voltage: 380V/415V three-phase (varies by region)

• Dedicated transformer recommended for lines above 300 kW

• Power factor correction to 0.9+

Compressed Air:

• Pressure: 6-8 bar (85-115 psi)

• Flow: 2-5 m³/min depending on line size

• Clean, dry air required (filtered and dried)

• Used for pneumatic controls, brakes, and splicers

Steam/Heat Source (Traditional Lines):

• Steam boiler: 2-8 tons/hour capacity

• Steam pressure: 8-12 bar

• Condensate return system

• Water treatment for boiler feed

• Annual boiler inspection and certification required

Heat Source (Boiler-Free Lines):

• Electric heating only — no steam boiler needed

• Saves boiler investment ($50,000-200,000)

• Saves boiler room space (30-50 m²)

• No water treatment or emissions compliance for boiler

• Significantly simpler utility infrastructure

Water Supply:

• Adhesive preparation: Clean water for glue kitchen

• Equipment cooling: Where applicable

• Fire suppression system

• Flow: 5-10 m³/hour typical

Phase 3: Factory Layout Design

Recommended Layout Sequence:

1. Paper roll storage (near line entry, climate-controlled)

2. Mill roll stands (line entry point)

3. Single facer(s) and preheaters

4. Bridge conveyors

5. Glue machine and double backer

6. Slitter scorer and cut-off

7. Stacker and finished board storage

8. Waste handling and trim removal

Supporting Areas:

• Glue kitchen: Adjacent to line, 20-40 m²

• Maintenance workshop: Near line, with overhead crane access

• Electrical room: Climate-controlled, accessible

• Quality lab: 15-25 m² for testing equipment

• Office and control room: Overlooking production floor

Material Flow:

• Paper rolls in → Corrugating line → Finished sheets out

• Minimize transport distance for heavy paper rolls

• Finished board storage close to converting area

• Waste paper collection point accessible for recycling

Phase 4: Foundation and Anchoring

Machine Foundation Requirements:

• Each major section requires independent foundation

• Foundation design provided by equipment manufacturer

• Typical depth: 800-1500mm below floor level

• Anchor bolts: Grade 8.8 or higher, epoxy-anchored

• Allow 28 days concrete curing before machine placement

Installation Sequence:

1. Double backer (heaviest section, central reference point)

2. Single facer(s) — aligned to double backer

3. Bridge conveyors between sections

4. Mill roll stands at line entry

5. Slitter scorer, cut-off, and stacker at exit

6. Glue kitchen and piping connections

7. Electrical and control system wiring

8. Utility connections (power, air, steam/heat, water)

Phase 5: Installation Timeline

Typical Schedule for a 5-Ply Line:

• Foundation construction: 4-6 weeks

• Equipment shipping: 4-8 weeks (depending on origin)

• Mechanical installation: 3-4 weeks

• Electrical and utility connection: 2-3 weeks

• Testing and commissioning: 2-3 weeks

• Operator training: 1-2 weeks

• Total project: 4-6 months from order to production

Boiler-Free Advantage:

Boiler-free lines save 2-4 weeks on installation:

• No boiler procurement, installation, or certification

• No steam piping throughout the factory

• Simpler utility connections

• Faster commissioning (no boiler warm-up and tuning)

Phase 6: Pre-Installation Checklist

Before equipment arrives, confirm:

• All foundations completed and cured

• Building weatherproof and secure

• Electrical supply connected and tested

• Compressed air system operational

• Overhead crane or lifting equipment available

• Access roads for delivery trucks (container unloading)

• Storage area for crated equipment components

• Installation team mobilized (manufacturer technicians + local crew)

• Permits and inspections completed
