Japanese Patent JPH0570556
Kind Code:
B2
Abstract:
This relates to the cutting or trimming of a blow molded polyester resin article utilizing a CO2 laser. The article is axially positioned and rotated while the laser beam is focused and concentrated on a preselected portion of the article. The laser beam beneficially vaporizes the polyester resin in the cutting thereof as opposed to forming a dust. Further, the action of the laser is one wherein a certain melting occurs so that the resultant cut edge of the retained part of the article is rounded and sealed.
