摘要

Two pairs of spaced conveyor chains 18, 19 and 20, 21 are disposed one inside the other, and traverse identical rectangular runs between an infeed station 28 and an outfeed station 58. Each pair carries a respective serial array of pickup devices 22-23 and 33-41 arranged in two oppositely spaced groups for accommodating rolls of paper towels or the like. The conveyor chain pairs are independently driven by separate motors 6, 7 in such a manner that while one group of pickup devices is being intermittently stepped or indexed through the infeed station for loading, the other, previously loaded group is continuously advanced to the outfeed station for unloading and thereafter back to the vacated infeed station.
