Abstract: A rotary cutting head for severing the packaging material webs in a wrapping machine includes an elongate saw type of knife blade mounted with parallelogram linkage on one of the cutting head shafts. A face cam, coaxial with the shaft, actuates a spring biased cam follower that is connected to the knife blade. The spring(s) during each revolution of the knife blade are sequentially armed by the cam, and then triggered or released to provide an instantaneous power impulse that rapidly swings the knife blade through the web.

Abstract: The disclosure concerns a wrapping machine, a wrapping method, and the package formed by the machine and method. The side edges of a single web are folded around two laterally aligned articles and edge sealed to the remaining web near a central tear line along the single thickness of web interconnecting the packages. By forming two packages from a single web, the web can be run about as fast as any single web used in the known single file wrapping method, whereby the output of the machine in finished packages is substantially doubled over the output of a machine producing packages with the single file method.
