the line of cans are divided by means of the can line
divider 14. Branches 12 and 13 are similar in construc

preferred form of the invention shown in FIG. 1, each

This invention relates to a new and improved can line
divider. More particularly, this invention relates to a 10 into an outwardly slightly downwardly extending stretch

well as preventing the escape of cans therefrom. Fixed
