PROCESS FOR REMOVING RETURNABLE BOTTLES FROM CIRCULATION |
摘要 |
11 To determine whether stress cracks are present in the bottom area of a plastic bottle which make it unfit for further use, the bottle bottom is scanned in the potential crack region by the measuring beam of a laser distance-measuring instrument. From its output signal, the prevalence and depth of the cracks can be identified sufficiently to enable a decision to be made on the removal of the bottle from circulation.
