Equipment for production of cotton swabs
View Patent ↗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.
1. Equipment for the manufacture of a swab article comprising:
(i) a station for delivering a stick onto a conveyor;
(ii) a station for applying an adhesive to at least one end of the stick being carried by the conveyor;
(iii) a station for joining a coil of cotton to the adhesive applied end of the stick;
(iv) a station for shaping the joined cotton into a bud by contacting the joined cotton with a means for shaping, force being applied by the means in a direction parallel to a length of the stick, the means traveling in a direction perpendicular to the length of the stick at a rate different from that of the conveyor.
2. The equipment according to claim 1 wherein the shaping means travels at a rate greater than that of the conveyor.
3. The equipment according to claim 1 wherein the shaping means travels at a rate slower than that of the conveyor.
4. The equipment according to claim 1 wherein the shaping means has a shape on a surface contacting the joined cotton which is a teardrop shape.
