Fabric straightener Orthofact RMB-15

weftautomaticmechanical

Overview
The Orthofact RMB-15 is an automatic pin-wheel straightening system designed to correct asymmetrical distortions in textile webs. By generating defined lateral (cross) tension with freewheeling, inclined pin wheels, the unit restores distorted warp and weft threads to their intended paths, correcting wavy and S-shaped deformations before downstream processes.

Product highlights

• High lateral tension capability
• Adjustable unclipping roller
• Bypass function for non-compatible products
• Intelligent drive with tension control

Customer benefits

• Effective straightening even without optical detection
• Fast and reliable correction of irregular distortions
• Performs on asymmetric warp/weft defects
• Reduces material spoilage and rework

Special features

• Unclipping roller with infinitely variable adjustment to minimise residual bow and edge distortions
• Intelligent drive station with special tension control for minimal product tension; automatic activation/deactivation (e.g. in case of blockages)
• Bypass function activated by push button for products that cannot be straightened with the pin wheel
• Intelligent wheel following compensates product offset, poor seams, fringes and edge dents to prevent product loss
• Width jump function allows pulling in wider products without separate pull-in procedures, reducing downtime
• Break function lowers lateral tension to a preset level when the line stops (e.g. breaks or line work) to protect the product

Innovative pin wheel control
Pneumatic inclined positioning of the wheels ensures a constant straightening effect. A spring-generated counter-force compensates friction and tolerances for uniform, symmetrical wheel alignment. The optimized mechanical design reduces maintenance requirements.

Area of application

• Correction of asymmetrical fabric distortions (wavy, S-shaped)
• Suitable for non-elastic fabrics that cannot be straightened by detection systems
• Used prior to processes such as decatizing or digital printing
• Applicable across a wide range of distortion challenges in textile production
