Abstract: Systems and methods for in-line inspection of plastic blow molded containers. The inspection system may comprise a plurality of emitter assemblies arranged in a vertical array. Each emitter assembly may cyclically emit light energy in at least two different narrow wavelength bands at a container as the container passes through an inspection area. The system may also comprise a plurality of broadband photodetectors arranged in a vertical array, each photodetector facing at least one of the emitter assemblies with the inspection area therebetween such that the photodetectors are capable of sensing light energy that passes through the container when it is in the inspection area. The system may also comprise a processor in communication with the photodetectors for determining a characteristic of the container based on signals from the photodetectors.

Abstract: A method and apparatus for manufacturing and inspecting plastic containers. The apparatus may comprise a blow-molder comprising a plurality of molds and spindles for forming a plastic container from a preform. The apparatus may also comprise an inspection device, located in the blow-molder, for inspecting the plastic container after formation by the blow-molder.
