Device for automatically attaching an arrow label

摘要

The disclosure describes a method of automatically attaching an arrow label in the center hole of a ball, skein or package of yarn or thread wound onto a winding mandrel. The arrow label is coaxially aligned with the winding mandrel. During withdrawal of the ball of yarn from the winding mandrel the ball slides with its center hole onto the label. Subsequently, the ball of yarn is transported away together with the label by a conveyor means. A device for carrying out this method is provided with a movable label conveyor which positions the arrow labels one at a time and tip first at the winding mandrel. A movable gripping device then withdraws the ball of yarn from the winding mandrel, slides it over the shaft of the arrow label and transfers the labelled ball to ball conveyor.
