High-Speed 250m/min Five-Roller Haul-Off – PP Band Line

In PP strapping production, the stretched tape needs to be transported to subsequent processes at high speed and with stability. This production line is equipped with a high-speed five-roller haul-off unit with φ268mm roller diameter, 450mm face width, chrome-plated and polished surface (hardness HRC58-60), haul-off speed range 0-250 m/min, adjustment accuracy ±1 m/min, and 15KW motor power. The five-roller structure provides a larger wrap angle and more uniform pressure distribution, with strong gripping force to effectively prevent slippage at high speeds. Located after the extension box and before the embossing machine, this unit ensures the tape passes at high speed with constant tension, providing a stable speed reference for subsequent embossing and winding.

• High speed capability: Up to 250 m/min for high output production
• Five-roller structure: Large wrap angle, uniform friction, anti-slip
• High precision speed control: ±1 m/min for closed-loop synchronization
• Hard chrome rollers: HRC58-60 hardness, wear-resistant and non-damaging
• Large diameter: φ268mm ensures sufficient contact arc length
• Uniform pressure: Pneumatic pressure roller adjustment ensures consistent tension across 6 strands
• Low vibration: Precision dynamically balanced rollers for smooth high-speed operation
• Long life: Chrome layer resists wear, maintains smooth surface
• Easy maintenance: Adjustable roller gap, convenient bearing lubrication
• Linkage ready: Speed signals synchronized with main drive and winder
