ABSTRACT:
An improved control system for the cutting of spirally wound composite can "sticks" with accurate registration. Cutting knives, which cut a wound tube into sticks, are mounted on a servo-driven sled, which is in turn mounted on a reciprocating carriage. The point of cutting is controlled by adjusting the position of the carriage (for long term errors) and the sled (for short term errors). Factors analyzed to determine where the carriage and sled should be positioned include the phase relationship between the label and the carriage, the angle at which the label is wound onto the tube, the point at which the label is wound onto the tube, label stretch, and misprinting of reference marks on the label. Means may be included for automatically rejecting sticks which are out of registration.
