Abstract: A process and equipment for manufacture of a swab article is provided wherein a stick is placed onto a conveyor, adhesive is applied to one or both ends of the stick, a portion of cotton coil is attached to the adhesive bearing end, and a shaper bar or similar means forces the cotton to assume a teardrop profile by applying force parallel to the stick, wherein the shaper bar or similar means moves in a direction perpendicular to the stick at a different rate of speed than that of the stick. Differences in the rate of speed reduce tailing of cotton normally associated with drag.
