Mahlo Orthomat FMC12 detects both distorted bow and skew. The FMC12 features the TK12 camera which uses lamps with IR LEDs, thus utilising both transmitted and reflected light. The number of cameras depends on the product width.
The Mahlo Orthomat FMC12 features a number of scanners and lamps that are spaced evenly across the online material. The cloth runs between the sensors and lamps, and each pick or knitted course modulates the intensity of the light measured by the scanners. The repetitive nature of the passing picks or courses create a regular light-dark pattern, which generates a modulated signal in the scanner's receiver system. A centrally-pivoted, cylindrical lens in the scanner oscillates to a specific angle in relation to the passing picks. When the lens is parallel with the pick or course, signal modulation is at its maximum. lt then decreases as the oscillating lens progressively cuts across the weft line. Unwanted signals that differ from the frequency of the picks, knitted courses or rows of tufts are filtered out digitally, so that the system can analyse the pure bow and skew-related signals and, from those, automatically compute the weft or course configuration.
