ORTHOPAC FMC-15
Distortion detection - simply unique
Bow and skew detection
The Orthopac FMC automatic straightener is the heart and core of the Orthopac. The device consists of an optical scanning system and electronic control for distortion correction.
It is used primarily to detect and log residual distortions in the exit end of a system, e.g. with the stenter. Thread density can be determined at the same time. It can also be connected to external straightening machines then serving them as control unit.
Scanning principle according to the modulation principle via Fast Fourier transformation
Tracks down distortion in fabric
Skewing of the product during manufacture alters the structure of textile webs. A distorted product depreciates in useful value, affects subsequent processing and invites complaints.
The integrated optical distortion detection Orthopac FMC is capable of handling the variety of usual colours, print and Jacquard patterns as well as surface structures such as pile and loop.
The scanning system detects and analyses the regular basic structure of the weft threads, courses or rows of tufting. If necessary, their density is determined at the same time.
Product highlights
- Broadest scanning spectrum on the market
- Simple, intuitive operation
- Automatic scanning even of the most complex product structures
Customer benefits
- Optimized optics ensure maximum possible resolution of the angle of distortion
- Direct, instantaneous signal processing determines the angle in a trice
- Optimized back and incident lighting
Area of application
For the control of various straightening devices, for pull-off rollers, chain differentials and multiple motor drives: The FMC distortion detection Orthopac constitutes the universal automatic straightening system. It can be installed upstream and downstream of a wide variety of production plants.
Equipped with digital scanning and state-ofthe-art processor technology, it adapts the control automatically to different textiles and displays distortion changes ergonomically and conveniently on the screen.
Residual distortion and residual moisture at the stenter outlet
Nice to see on the front left: a measuring roll of the residual moisture measurement Textometer RMS and behind the fabric the counter roll. The electrical conductivity of the web provides the residual moisture.

The Orthopac FMC at the stenter outlet is often used additionally to a weft straightener on the inlet for quality control and logging. Here a version with manual scanner positioning (recognizable by the snap-in holes on the underside of the guide rail)
Variants
- Orthopac FMC T: Standard bridge with optical scanning system and two guide rollers

Patcontrol PCS-15 scanning for pattern distortion at the feed- and delivery end. Residual moisture module Textometer RMS and exhaust air moisture module Ecomat AML control the drying processes.
To log the quality of the fabric after the fixing process, a scanning bridge Orthopac FMC scans for web distortion, a Patcontrol PCS for printing pattern distortion, the Wilot WMR determines the product width and the Textometer RMS the residual moisture. An extensive quality report is generated.
