Abstract

A flat bed knitted machine has a slotted needle bed with a carriage that can alise. On this carriage are a pair of dual magnet Hall-effect devices which moves across slots in the bed. These devices are actuated by steel in the bed as they move between the slots and are connected to a circuit responsive to their operation. The devices are located wrt the slots to generate out of phase signals from which the direction of the carriage can be determined. S strip magnet extends across the slots that are traversed by the Hall effect devices and is fixed to the needle bed on the opposite side of the slots. This pulse generation system is suitable for the control of automatic knitting machines and is cheap and reliable.
