<p>To provide a flat knitting machine capable of detecting, at high sensitivity, the abnormal vibration involved in the abnormal contact of the carriage and the knitting needle, and a method of detecting abnormal vibration. The flat knitting machine includes a needle bed 1 in which a plurality of knitting needles is arranged in parallel, and a carriage 2 for moving the knitting needles forward and backward by reciprocating on the needle bed 1. The carriage 2 includes vibration detection means (vibration sensor 4), which vibration detection means detects vibration that occurs in a direction intersecting a traveling direction of the carriage 2. Error judgment means determines presence and absence of abnormal vibration by abnormal contact of the carriage 2 and the knitting needle based on such a detection result. The abnormal vibration can be detected distinguished from the vibration involved in the normal knitting even if the traveling speed of the carriage 2 is high.</p> |
