T500

T500 Web Tension Controller

The T500 is a fully automatic web tension controller for roll-to-roll production lines in printing, packaging, papermaking, textile printing and related converting processes. It is used where stable web tension affects print registration, coating consistency, rewinding quality, inspection accuracy and overall production stability.

Position it as a practical controller for stabilizing unwinding, rewinding or intermediate tension control zones. Final configuration should be selected according to material, line speed, tension range, brake or clutch type and machine control method.

Key Features

16-bit high-precision AD sampling with 1 us sampling time for fast signal response.
Supports high-precision sensor signal processing for automatic web tension control.
Can drive magnetic powder brakes and work with single or dual pressure sensors.
Supports automatic control modes according to machine configuration and project requirements.
Helps reduce wrinkles, web stretching, unstable winding and quality defects caused by tension fluctuation.
Suitable for printing, packaging, coating, laminating, slitting, rewinding, paper, film, foil, textile and nonwoven processes.

Frequently Asked Questions

Are you a factory?

Bainary is an independent technology and international trade company. We support overseas customers through application review, model selection, export coordination, and long-term project follow-up, backed by selected Chinese manufacturing resources.

What information should I send before asking for a quotation?

Please send material type, web width, line speed, machine type, installation position, defect type, sample photos or videos, required inspection target and available space. If the project is about web guiding or tension control, photos of the current machine section are also useful.

Can one inspection system work for all materials?

No. Transparent film, printed labels, paper, foil and nonwoven materials may need different cameras, lighting, sensors or installation positions. A short technical check before quotation reduces the chance of selecting the wrong system.

What is the difference between web inspection and 100% print inspection?

A web inspection system helps operators observe high-speed printed images more clearly. A 100% print inspection system automatically checks the full web and records defects with software. The right choice depends on defect type, speed, width and required quality control level.

Why do web guiding and tension control matter for inspection?

If the web moves sideways, wrinkles or tension changes heavily, the camera may not see the same print area consistently. Stable guiding and tension often make inspection more reliable.

Can Bainary help with non-standard inspection cases?

Yes. For uncertain cases, Bainary can collect samples, videos and defect descriptions first, then coordinate feasibility evaluation before formal quotation.

Which applications are suitable?

Flexible packaging, labels, paper converting, film and foil converting, nonwoven production, coating, lamination, slitting, rewinding, printing and bag-making lines are typical applications.

What happens after inquiry?

Bainary first checks the application information. If the requirement is clear, we recommend a product direction and quotation path. If not, we ask for missing line parameters, sample images or videos before pushing the project forward.
