Abstract

A container feeding system is shown having an unscrambler having an unscrambler bowl providing a track or channel that is adjustable such that it can accommodate bottles of varying sizes. The system comprises an adjustable chute that is also adjustable and having a chute channel or track that is also adjustable to accommodate containers of varying sizes when the containers are conveyed from the unscrambling bowl, through the adjustable chute, and to a subsequent processing station.
