Distortion control system
The Orthopac FMC EP is a compact bridge only with optical scanning system. It fits in easily even under tight space conditions and can control external weft straighteners.
Orthopac FMC T: Standard bridge with optical scanning system and two guide rollers. The rollers provide straightforward web guiding.
Scanning principle by light-dark modulation using Fast Fourier Transformation
Bow and skew detection and control
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.
- 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
- Broadest scanning spectrum on the market
- Simple, intuitive operation
- Automatic scanning even of the most complex product structures
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.
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.
