ABSTRACT:
A wrapping machine assembly accelerates articles from a supply conveyor to a wrapping conveyor. Separating bars moved in an orbit over the accelerating portion of the assembly enter into the gap between articles created by acceleration of the leading article or articles. The separating bars and the accelerating portion of the machine are driven intermittently by a drive transmission which is synchronized and driven cyclically with the wrapping conveyor. The intermittent drive which forms the novelty of this invention has a belt loop driven continuously in synchronism with the wrapping conveyor. The belt loop drives an accelerating conveyor and the separating bars, but the driving motion is converted to intermittent motion by a pair of idler rolls which engage the opposite reaches of the belt loop, and swing transversely of the belt reaches to alternately lengthen one reach and shorten the other reach. The idler rolls are carried on a swingable support, and the support is oscillated in the plane of the rolls and belt by crank or cam means driven by the input drive source to the intermittent drive.
