Abstract: A packaging machine includes a carton feeder with rotary feeders that select, transport, and partially erect collapsed sleeve-type cartons in preparation for loading articles into each partially erected carton before its ends are sealed. A guide causes the collapsed carton to conform to the orbital path of a transfer feeder so as to optimize its presentation for engagement by an erecting feeder. An extended carton hold down member stabilizes the collapsed carton so as to enable the transfer and the erecting feeders to briefly engage the collapsed carton simultaneously, thereby partially erecting the carton, while preventing fluttering and jamming caused by premature release of the carton. The guide also prevents the extended carton hold down member from interfering with the passage of the collapsed carton. The rear portion of the carton hold down member provides stabilizing pressure to prevent the carton from collapsing before it is loaded.
