Abstract
A system and method for applying adhesive to at least a first end of a rod-shaped member, such as a cotton swab stick includes a carrier, an adhesive applicator, and a rotator device. The carrier conveys the rod-shaped member or stick in a machine direction and also allows rotation of the rod-shaped member about its longitudinal axis. The adhesive applicator includes an application surface positioned to engage the first end of the rod-shaped member. The application surface includes at least one discharge passage for applying adhesive to the first end of the rod-shaped member. The rotator device rotates the rod relative to the application surface and about its longitudinal axis as the rod-shaped member is conveyed along the application surface.
