Orthopac RVMC -20 plus
Automatic weft straightener with double scanning
Orthopac RVMC-20 plus with double scanning - the plus to the classic straightener.
Straight fabric from the first centimetre, even with with highly variable distortions.
Feed Forward and Closed Loop Control at the same time!
The Orthopac RVMC–20 plus combines two overlapping control circuits.
The newly designed scanning module makes it very easy to retrofit existing Orthopac RVMC–15 straighteners in the production line. This upgrades the device to an Orthopac RVMC–15 plus.
The Orthopac RVMC plus straightening system completes the RVMC / RXVMC model series.

Feed Forward and Closed Loop Control at the same time!
Two scanning units, one before and one after the straightening rollers, combined with an AI-based controller concept, guarantee the greatest possible control over the straightening process and minimised residual distortion.
The Orthopac RVMC–20 plus builds on the success of the tried and tested Orthopac series and is specially designed for processing textiles with highly variable distortions (high distortion dynamics).
Product highlights
- Combination of Feed Forward and Closed Loop Control
- AI-based control system
- Reliable standard components
Customer benefits
- Precise control with high distortion dynamics
- Savings on raw materials
- Sustainable production through upcycling of existing machines
- Increased efficiency
Sensors
Sensors for the detection of distortion in textiles
The precise and correct determination of distortion on running textile webs is the basis for successful weft straightening. Mahlo offers a wide range of sensors for this task. Thus, all conceivable applications and requirements can be covered.

Modular process control system for the textile industry
Textile manufacturers and textile outfitters are fighting with increasing production and energy costs, declining profit margins, shorter production times as well as greater requirements on quality and flexibility. Cost-efficient and quality-focused textile outfitting thus becomes increasingly important. Sustained production and the trend to higher-quality, technically sophisticated fabrics also play a major role.
Regardless of the challenges of the textile industry – Mahlo has the right solutions ready. The broad range of applications for textile production by Mahlo is based on experience reaching back to the year 1945.
Orthopac is a modular straightening and process control system available throughout the entire process of textile outfitting. It combines the functionality of a weft straightener with that of a process control system in one compact device. It automatically ensures a straight-thread product before and after the drying or fixing process and optimises the processes all around the stenter.
This increases quality and saves resources and energy. The modular design of the system allows its flexible adaptation to all applications. Both, standard requirements and highly customized demands are thus met.
- At the feed end of a stenter
- At the feed end of a levelling stenter
- On decatisers
- Ahead of a printing machine
- Between an open width washing machine and drum dryer
- On coating ranges ahead of the coater at the feed end of a
flame laminator - At the feed end of wide compactors for knitgoods
- etc.
The touchscreen of the system displays the measurements. Individually modifiable displays of the measured values facilitate easy monitoring of the complete process by the user. Various software packages (FULL or BASE) allow adjusting visualization and operating concept to different demands on detectability and user convenience.
- The FMC full version offers all setting capabilities and options to the entire depth. The full potential of the straightening system can thus be utilized.
- The FMC Base version focuses on the essential functions of the system and offers a compact and simple overview for thecontrol of the processes.
The weft straightener Orthopac with integrated web distortion detection forms the basis of the modular design. Additional intelligent sensors can be connected to the control system via a bus connection. The following process parameters can be measured, visualized, controlled and documented by means of special software packages (mLog):
- Weft thread or course skew / skew and bow rollers of the weft straightener Orthopac
- High moisture / squeezing pressure
- Thread or course density / over-feed
- Exhaust air humidity / fan speed / flap opening
- Surface temperature / product web speed and dwell time
- Basis weight / over-feed
- Residual moisture / product web speed
- Stretch and Shrinkage / over-feed
- Product width
