Multi-Stage Haul-Off System (Low-Speed & High-Speed Units) for Precise Tension Control
Product Introduction

Tension control is a critical factor affecting product thickness uniformity, stretching orientation effectiveness, and final winding quality in PP strapping production. This production line utilizes a multi-stage haul-off system consisting of a low-speed three-roller haul-off unit (0-40 m/min), a high-speed five-roller haul-off unit (0-250 m/min), and multiple high-speed three-roller haul-off units, forming a stepped speed and tension control network. The low-speed unit stabilizes the nascent tape after extrusion, while the high-speed units provide precise tension adjustment after stretching and setting. Multi-stage haul-off combined with closed-loop speed control ensures constant, fluctuation-free tension across all sections, providing a solid foundation for high-precision, high-speed production.

Main Specifications

Customer Questions & Answers
Why are both low-speed and high-speed haul-off units needed?
The low-speed unit stabilizes the nascent tape after extrusion and before stretching, preventing accidental deformation of not-fully-cooled tape. The high-speed units transport the stretched and set finished tape, meeting high line speed requirements. Stage-specific control optimizes tension matching at each section, improving overall stability.
What are the advantages of a five-roller haul-off over a three-roller one?
The five-roller structure provides a larger wrap angle and more uniform pressure distribution, offering stronger gripping force. This is especially beneficial for high-speed operation or smooth-surfaced PP tape, effectively preventing line speed fluctuations and tension spikes caused by slippage.
How is speed synchronization ensured among multiple haul-off units?
The entire line uses PLC closed-loop coordinated control. The operator sets the main line speed on the touch screen, and the system automatically calculates the speed ratios for each haul-off unit, precisely executed via inverters. Individual units can be fine-tuned independently to suit different draw ratios and process requirements.
