Product Overview
The LV‑2 BOPP Tape High‑Speed Coating Machine is a jumbo roll coating system built for small‑to‑medium adhesive tape manufacturers. It adopts comma‑roller transfer coating technology.
This system precisely applies water‑based pressure‑sensitive adhesive onto BOPP film. The coated film goes through oven drying and gets wound into large‑diameter jumbo rolls for subsequent slitting into finished tapes.
It delivers 500 mm effective coating width, with adjustable coating speed ranging from 7 to 30 meters per minute. It comes with a single‑shaft winding unit for a maximum 600 mm winding diameter.
Its comma‑roller coating structure delivers precise control over adhesive layer thickness. It is well‑suited for jumbo roll production that demands consistent coating uniformity.
Working Principle
BOPP film unwinds from the feed unit. It travels through the tension control system to reach the coating head.
The comma‑roller transfer coating system uses a comma roller paired with a doctor blade. It evenly spreads pressure‑sensitive adhesive and accurately sets coating thickness across the film surface.
The coated substrate enters the oven chamber. Hot air circulation fully dries and cures the adhesive layer inside the oven.
After drying, the web passes over cooling rollers. Finally, the single‑shaft winding system winds it into 600 mm large‑diameter jumbo rolls.
Process Flow: Unwinding → Tension Control → Comma‑Roller Transfer Coating → Oven Drying → Cooling → Single‑Shaft Winding (Jumbo Roll)
Key Advantages
- Precision Comma‑Roller Coating: The comma roller with doctor blade achieves tighter adhesive‑thickness control than standard two‑roller coating. It brings better coating uniformity and stable jumbo‑roll quality.
- 600 mm Large‑Diameter Jumbo Rolls: Single‑shaft winding supports up to 600 mm roll diameter. It boosts output per roll, reduces roll‑change frequency and raises production efficiency for downstream slitting.
- Simple & Reliable Single‑Shaft Winding: The single‑station winding structure is robust and easy to maintain. Fewer roll changes keep overall operational efficiency at a high level.
- Multiple Heating Options: It supports electric, hot‑air, steam and thermal‑oil heating. You can match the heating mode to your factory’s existing energy supply.
- Adjustable Speed for Versatility: Stepless speed ranges from 7‑30 m/min. It adapts to different adhesive thicknesses, adhesive types and drying conditions for various BOPP tape jumbo‑roll outputs.

Structure & Key Components
Comma‑Roller Coating System
This comma‑roller transfer coating unit uses a precision‑machined roller and doctor‑blade assembly. It delivers fine‑tuned control over adhesive layer thickness.
It outperforms conventional two‑roller coating systems. It produces higher coating uniformity for jumbo‑roll runs with consistent adhesive thickness.
Oven Drying System
The oven adopts hot‑air circulation drying. Internal air guides evenly distribute hot air over coated surfaces for full adhesive curing.
It supports electric, hot‑air, steam and thermal‑oil heat sources. Operators adjust temperature according to adhesive properties and production speed.
Single‑Shaft Winding System
The single‑station winding shaft supports a maximum 600 mm roll diameter for large‑size BOPP jumbo rolls.
Adjustable winding tension keeps rolls tight with neat edges. It outputs premium jumbo rolls ready for downstream slitting. The single‑shaft layout is simple, dependable and easy to service.
Drive & Control System
Variable‑frequency drive enables stepless speed regulation across 7‑30 m/min. Independent tension control is fitted for each processing section.
It maintains stable film travel during coating and winding. It prevents wrinkles, web offset and film breakage to secure high‑quality large‑diameter jumbo rolls.
Optional Configurations
This model comes with standard fixed hardware. You may select heating mode among electric, hot‑air, steam or thermal‑oil to match your factory energy setup. All other parts follow standard delivery specifications.
Typical Application Scenarios
- Jumbo Roll Production for SME Tape Factories: Small‑to‑medium tape manufacturers with existing slitting equipment can run the LV‑2. It produces 600 mm BOPP jumbo rolls for further slitting into finished tapes and completes your coating‑slitting workflow.
- Jumbo Roll Wholesale Supply: Manufacturers supplying jumbo rolls to converters and tape distributors benefit greatly. Comma‑roller coating guarantees stable quality, while 600 mm large‑diameter rolls raise per‑batch output for simpler handling and storage.
- Printed Tape Jumbo Roll Production: It suits carton‑sealing and custom‑logo printed tapes requiring smooth adhesive surfaces. Precision comma‑roller coating delivers uniform adhesive layers and improves printing and slitting yield rates.
Packaging & Shipping
The machine is packed in export‑grade wooden crates with moisture‑proof and anti‑rust interior treatment for long‑haul overseas transit.
Trade terms including FOB and CIF are available. Actual lead‑time depends on configuration and order quantity as stated in formal contracts.
