Four Independent Air Knives for Effective Water Removal Before Winding
Product Introduction

Thorough removal of residual moisture from PP strap surfaces after secondary cooling/setting and before winding is critical. This production line features four independent high-pressure air knife units positioned at the secondary setting water tank outlet. Each unit corresponds to one product strand, delivering uniform, powerful airflow that acts as a precision "knife" to efficiently scrape water film from both top and bottom strap surfaces. This ensures completely dry product entry into the winding process, preventing issues such as unclear embossing, winding adhesion, roll mildew, or product corrosion caused by trapped moisture, thereby guaranteeing final product quality and storage stability.

Main Specifications
  • Configuration: 4 independent air knife sets, one-to-one对应 with the 4 product strands
  • Working Principle: Utilizes compressed air to generate high-speed laminar airflow for surface blow-off
  • Core Function: Thoroughly dries residual surface moisture on the product before winding
  • Direct Benefit: Improves embossing and winding quality, prevents moisture-related defects
Technical Parameters

Installation Position Outlet of secondary setting water tank, before the winding process
Target Effect Achieves visually dry product surface with no water stains
Customer Questions & Answers
Q: Could the air from the knives blow the strap off course or affect its tension?
A: When properly installed and adjusted, no. Our air knives are designed to produce a broad, uniform laminar air curtain with gentle pressure but large coverage. By fine-tuning the air knife angle, the airflow acts tangentially on the strap surface, primarily generating shear force to peel off moisture, not vertical impact force, thus having minimal effect on the strap's stable running path and tension.
Q: Is the compressed air consumption high? What are the requirements for the factory air supply?
A: Air knives are intermittent air-consuming devices, operating only when the production line is running. The consumption per knife is not high; running all four simultaneously is a general load for a medium-sized compressed air system. The core requirement is that the air must be dry and clean, as damp or oily compressed air would contaminate the product surface, achieving the opposite effect. It is recommended to have a refrigerated air dryer and precision filter upstream.
Q: If only producing 2 or 3 strands, should the unused air knives be turned off?
A: Yes, for energy saving and noise reduction, the air knives corresponding to idle stations can be turned off. The air supply valves are typically independently controlled for easy operation. We recommend performing this action synchronized during shutdown for specification changes.
