Flight Lug For Octagonal Cartons

摘要

A carton conveyer for a packaging machine has upper and lower flights to which sets of flight lugs are attached. Each set of flight lugs comprises leading flight lugs and trailing flight lugs and the leading flight lugs have recesses that face and oppose recesses on the trailing flight lugs. The recesses are formed to confine an open carton therebetween. Notches are formed in the flight lugs in such a way that movement of the leading and trailing flight lugs toward one another causes an un-erected carton between the lugs to be captured and erected.
