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
