Abstract

A packaging machine wraps an article with a web of patterned wrapping paper as it is continuously formed into a sleeve, and seals or cuts or both seals and cuts the front and rear ends of a sleeve enclosure in which the article is wrapped. A timing adjustment device for the packaging machine includes input means for setting an operating pitch of a seal cutter or the like and a thickness of the article, a processor for computing an initial angle or position of the seal cutter or the like based on the settings for the operating pitch and the article thickness to establish timing of operation of the seal cutter or the like with respect to the article fed by a feed conveyor and the patterned wrapping paper and for issuing a control signal based on the result of computation, and a control motor for adjusting a timing mechanism for the seal cutter or the like based on the control signal.
