ABSTRACT:
A yarn monitor for an automatic cross winding and yarn assembly machine in which at least two yarns are wound in parallel from two run-off bobbins onto a cross bobbin. The monitor includes a drive roller for driving round the cross bobbin, a driver for rotating the drive roller in two opposite directions and a wind-off eye for leading the two yarns to the cross bobbin. A yarn guide is provided for axially guiding the yarns on the cross bobbin, the yarn guide being installed between the cross bobbin and the wind-off eye for controlling and correcting the position of the two yarns with respect to one another. The yarn guide comprises a cutting apparatus for cutting at least one of the yarns and a driver for the cutting apparatus. A yarn guide is provided for guiding the yarns co-operating with the cutting apparatus. Sensors are provided for detecting the yarns in the yarn guide and for controlling the cutting apparatus. Guiding apparatus is provided for putting the yarns into the cutting apparatus and the yarn guide. A gripper and holder is provided for gripping and holding the yarn ends left after cutting on the cross bobbin and a central control device is provided for controlling all the apparatus.
