ABSTRACT:
In a yarn feeder (2), the yarn feed may be effected by a yarn reserve (11) support spool (2), which is arranged to rotate by means of a motor (60). The yarn is taken up by and unwound from the spool as the latter rotates. Unwinding of the yarn reserve on the spool is not controlled. The size of the yarn reserve is monitored and yarn take-up is controlled accordingly. The unit also includes electrically contactless sensing and control devices (3), which are preferably located immediately adjacent to the rotary spool. The unit (3) is designed to sense the presence and quantity of yarn on the yarn reserve support surface (10) of the spool. The unit also controls the said motor.
