Abstract
A method for detecting defects in a surface of a container includes: providing a plastic container having a longitudinal axis and a surface; directing ultraviolet radiation from a source to an area of the surface; sensing a portion the ultraviolet radiation that is reflected from the surface of the plastic container; and generating a signal from the sensed portion of the ultraviolet radiation representing a defect in the surface plastic container.

A method for detecting defects in a surface of a container including:
- providing a plastic container having a longitudinal axis and a surface;
- directing ultraviolet radiation from a source to the surface of the container;
- sensing a portion the radiation reflected from the surface of the container;
- and
- generating a signal from the sensed portion of the reflected radiation representing a defect in the surface of the container.
2 more elements
A surface defect detection system comprising:
- a source of ultraviolet radiation;
- a plastic container having a surface;
- means for directing said container along a path through the radiation;
- detecting means for receiving a portion of the ultraviolet radiation reflected from the surface of said plastic container, and being responsive to generate a signal;
- and
- a computer means connected to said detecting means and being responsive to the generated signal for calculating a defect value, comparing the defect value with stored standards, and indicating one of acceptance and rejection for said plastic container.
