  • Methods and apparatus for preventing filaments from lapping a roll
    Patent number: 4739540
    Abstract: In an apparatus for advancing a bundle of filaments, a pair of rolls defines a nip through which the bundle passes. A blower blows a stream of gas across an outer periphery of at least one of the rolls in a direction opposite the direction of rotation of that roll to dislodge adhering filaments therefrom. This prevents filaments from lapping the roll. The gas stream forms an obtuse angle with a radius extending from the point of intersection of the gas stream and the roll periphery.
