【Abstract】 The newly-developed length gauge for the needled paper maker’s felt uses 2 infrared probes and 2 counters. The distance between the probes is fixed. It measures the running speed of the felt on the needle loom first, then calculates the precise length of the felt. This article introduces the research and development process of the length gauge and its application effect.更多还原
