Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
168 words
In a cartoner having a transport conveyor having an endless chain carrying a leading lug and an endless chain carrying a trailing lug, and a main drive for said cartoning machine connected to said endless chains, a mechanism for adjusting the spacing between leading and trailing lugs comprising, a direct connection from said main drive to said trailing lug conveyor, at least one phase variator forming the connecting between said main drive and said leading lug conveyor, to drive said leading lug conveyor in synchronism with said cartoner, said phase variator having a housing, a driving gear, a driven gear and an intermediate gear interconnecting the driving and driven gears, all said gears normally having no relative rotation, thereby functioning as a rigid drive coupling, a brake, means connecting said brake to said variator to cause a differential movement of said leading lug with respect to said main drive to vary the position of said leading lug with said trailing lug while said main drive drives said cartoner.
