PVC Electrical Tape Coating Machine | Dual-Coating Dual-Drying Mesh Roller Line

Is your PVC electrical tape factory facing these pain points: insufficient adhesive adhesion from single-side coating, finished product debonding caused by inadequate drying, lengthy setup times when switching colors or adhesives, or uneven winding during continuous production? The PVC Electrical Tape Coating Machine is built to solve exactly these problems — a dedicated system for producing PVC electrical tape master rolls using soft PVC film as the substrate coated with rubber-based pressure-sensitive adhesive. Using mesh roller coating technology, with an effective coating width of 1300mm, coating speed of 15m/min, hot blast stove heating, and equipped with dual coating systems (top adhesive + underlay adhesive) and dual drying systems (top adhesive drying + bottom adhesive drying). From automatic lifting unwind, through dual coating & dual drying, web guidance & accumulation, to automatic winding — all in one continuous flow. It is the core production equipment for scaled PVC electrical tape manufacturing.

Why Choose This Machine: Five Core Advantages

Every design feature targets the specific process requirements of PVC electrical tape production — helping you stabilize quality and boost efficiency:

• Dual coating system, strong adhesive adhesion: Equipped with an adhesive coating system (top adhesive) and an underlay coating system (bottom adhesive). First applies the bottom adhesive to enhance adhesion to the PVC film, then applies the top adhesive to ensure adhesive layer thickness and tack. The dual-coating process ensures finished products do not debond, with uniform adhesive layers — solving the industry pain point of insufficient adhesion from single-side coating.
• Dual drying system, thorough curing without debonding: Equipped with an adhesive drying system (top adhesive) and a bottom adhesive drying system. Hot blast stove heating with a total oven length of 37 meters ensures both bottom and top adhesives are fully and separately cured. Finished adhesive layers are stable, do not debond, do not bleed through, and maintain consistent quality during long-term storage.
• Mesh roller coating, precisely controlled adhesive weight: Uses mesh roller coating method with precisely controlled adhesive transfer. Delivers uniform, stable coating adapted to the characteristics of rubber-based pressure-sensitive adhesives. Quick and convenient setup when switching colors or adhesives, reducing setup waste and lowering production costs.
• Automatic unwind + web guidance & accumulation, precise web travel: Automatic lifting unwinder with maximum unwind diameter of φ600mm. Equipped with a deviation correction device and storage rack, ensuring stable, drift-free web travel. Roll changes without stopping the machine for high continuous production efficiency, with neat finished master roll end faces.
• Centralized control + well-known brand components, stable and reliable: The entire machine adopts centralized control with decentralized operation settings. All required configurations are manufactured by well-known domestic and foreign brands, ensuring machine quality and operational stability. Low failure rates reduce downtime and maintenance, with low long-term running costs.

  

Technical Specifications: The Hard Data

Five Core Systems Breakdown: Every Component Built for PVC Electrical Tape Process

The machine has a total length of approximately 37 meters. From PVC film unwind to electrical tape master roll rewind, five systems work in seamless sequence. The dual-coating, dual-drying process ensures adhesive adhesion and curing quality:

• Unwinding System

  Automatic lifting unwinder compatible with maximum φ600mm raw material rolls, 3-inch (76mm) paper tube. Stable, controllable unwind tension ensures smooth, drift-free web travel, providing a stable PVC film input for the subsequent coating process with convenient roll changes.

• Coating System

  Dual coating design including an adhesive coating system (top adhesive) and an underlay coating system (bottom adhesive). Uses mesh roller coating method — first applies bottom adhesive to enhance adhesion to the PVC film, then applies top adhesive to ensure adhesive layer thickness and tack. Precisely controlled adhesive transfer, adapted to the characteristics of rubber-based pressure-sensitive adhesives. Finished products do not debond with uniform adhesive layers.

• Drying Room System

  Dual drying design including an adhesive drying system (top adhesive) and a bottom adhesive drying system. Hot blast stove heating with a total oven length of 37 meters ensures both bottom and top adhesives are fully and separately cured. Finished adhesive layers are stable, do not debond, do not bleed through, and maintain consistent quality during long-term storage. Multiple independently controlled fans ensure uniform temperature.

• Winding System

  Equipped with a deviation correction device, storage rack, and winding machine. The deviation correction device detects the web edge position in real time and automatically adjusts the web path. The storage rack ensures roll changes without stopping the machine for uninterrupted continuous production. Uniform winding tension delivers neat end faces and appropriate tightness — ready for subsequent slitting processes with reduced slitting scrap rates.

• Electrical System

  The entire machine adopts centralized control with decentralized operation settings. All required configurations are manufactured by well-known domestic and foreign brands, ensuring machine quality and operational stability. Temperature, speed, tension, and other key parameters are centrally controlled, with each section independently operated — intuitive and convenient operation, low failure rates, reduced downtime and maintenance, with low long-term running costs.

Applications & Process Flow: Find Your Match

This machine is dedicated to the professional production of PVC electrical tape, with a clear and well-defined process flow:

• Raw materials: Soft PVC film (various colors) + Rubber-based pressure-sensitive adhesive (bottom adhesive + top adhesive)
• Process: Automatic unwind → Bottom adhesive coating → Bottom adhesive drying → Top adhesive coating → Top adhesive drying → Web guidance & accumulation → Automatic winding
• Finished product: PVC electrical tape master roll → Slitting by cutting machine → Packaging by packaging machine → PVC electrical tape finished small rolls
• Finished product applications: Electrical equipment protection, wire connector insulation wrapping, insulating layer fixing & sealing, automobile wiring harness insulation taping
• Product characteristics: PVC electrical tape is an industrial material made from soft PVC film as the base material coated with rubber-based pressure-sensitive adhesive. With good insulation performance, strong tack, and clear color separation, it is widely used in electrical insulation and wire harness taping. Also commonly known as insulating tape, electrical tape, or plastic tape.
