Product Overview
The Dhara J-Box Scray Unit is designed for continuous, non-stop fabric processing, serving as a controlled buffer at the inlet or outlet of textile finishing machines. Suitable for both woven and knitted fabrics, the unit enables smooth fabric accumulation, precise tension regulation, and uninterrupted machine operation—essential for modern, high-efficiency finishing plants.
Engineered for reliability and fabric safety, the Dhara J-Box Scray Unit ensures stable fabric flow, controlled dwell time, and consistent fabric presentation, even during speed variations between connected machines.
Process Function & Application
- Acts as a fabric storage and buffer system for continuous processing
- Allows upstream and downstream machines to operate independently
- Prevents fabric tension shocks during speed changes or stoppages
- Suitable for integration with washing ranges, dyeing lines, dryers, compactors, and finishing machines
Mechanical Design & Fabric Handling
- Fabric tension adjustment mechanism for controlled fabric accumulation
- AC inverter-controlled main traction roller, tape-wound for high grip and gentle fabric contact
- Optional pressure roller on driven roller for specific fabric applications
- Idler roller with ring system to guide fabric smoothly from driven cylinders
- Multiple stainless steel idler rollers ensuring stable and crease-free fabric transport
J-Box Platform & Accumulation System
- Stainless steel J-box platform sheet for corrosion resistance and long service life
- Low-friction Teflon sledges to minimize fabric drag and surface damage
- Optimized fabric stacking geometry to prevent creasing and rope marks
