Abstract
A chub packaging machine, or the like, incorporates a double-knife cut-off or severing device of the invention. Chub packages are elongate tubular packages which are gathered at their opposed ends and have metal clips clinched therearound to close those ends. The double-knife cut-off device is mounted on the closure head assembly of a conventional chub packaging machine, with appropriate modification, and produces a shorter and cleaner stub end on a chub package than heretofore available. The appreciable amounts of product trapped in the stub ends of chub packages formed on conventional chub machines are substantially eliminated by shortening the stub ends to approximately one-third the usual length. The double knife cut-off device severs a short gathered portion of the tubing between two packages at two spaced apart positions rather than in the center of the portion as heretofore known. A separate piece of package scrap is formed between the double knives as they cut through the short length of gathered tubing, and a scrap removing finger positioned between the knives removes that scrap from the path of travel of the individual packages so it may be conveniently collected and discarded.
