BTSR YARN FLOW SENSORS
This device consists in a number of sensors that electronically detect when the yarn is flowing and when the yarn is steady. During the production of the first sock, information about the yarn flow is stored into a memory on an electronic board (BTSR preparation). During the production of all the following socks, the device checks that the yarns flow with the same sequence as the first one. In case of errors, the machine stops avoiding the production of second choice socks.
