Sensor head adjusting method for needle monitoring device at knitting machine, involves providing viewing angle, distance, and position as adjustable in three steps, where viewing is adjusted in one step, and settings are maintained

摘要

The method involves providing a sensor head with an optical axis (1) at a viewing angle. The sensor head is provided in a direction of the optical axis at a distance (A). The sensor head is movable in a plane perpendicular to the optical axis in a position and is fixed. The viewing angle, distance, and position are provided as adjustable in three separate steps. The viewing angle is adjusted in one of the steps, and settings of the steps are maintained. An independent claim is also included for a needle monitoring device comprising an optical sensor unit.
