Automatic packaging machines with wear resistant parts

Abstract From the Canadian patent

An automatic packaging machine transports an object over a path having a freedom for both horizontal and vertical movement. Horizontal rails support a pair of guide blocks positioned to slide over the rails, Each of the guide blocks has a pair of spaced parallel slots with a T-shaped cross-section confronting individually associated ones of the rails. A replaceable wear resistant track is slidably captured within each of the T-shaped slots, to slide over an individually associated one of the rails. A vertical support bar interconnects the second guide blocks. An upper and a lower U-shaped block is attached to the vertical support bar at vertically spaced locations. A keeper is secured over …
