Abstract
A packaging machine includes an article conveyor for transporting articles in a flow direction and a plunger assembly for displacing articles from the article conveyor. The plunger assembly is supported and positioned by a system that includes a frame assembly and a pressure sensitive coupling as means for releasably fixing the position of the plunger assembly. The frame assembly includes a first frame structure that is attached to the plunger assembly and a second frame structure. The first frame structure and the second frame structure are slidably coupled to one another such that a resistive force that overcomes the holding power of the pressure sensitive coupling will cause the first frame structure to slide and translate the plunger assembly out of its operating position in which it can displace the articles.
