ABSTRACT:
An apparatus and method for applying coatings to yarns, particularly yarns to be utilized as dental floss. In a preferred arrangement, an array of parallel spaced yarns are continuously fed while being intermittently deflected by a cam or deflector. As the yarns are deflected, they enter a grooved liquid applicator, with the grooves maintaining a predetermined amount of liquid therein by capillary action. A predetermined amount of liquid is thus applied at intermittent or spaced locations along the length of the yarn. The method and apparatus is particularly suitable for providing dye at spaced locations along a continuous length of floss, thereby demarcating lengths suitable for individual use. Various aspects are also applicable to a variety of yarn coating and/or dyeing applications.
