Continuous blank feed method and device

摘要

A method and device for continuously feeding blanks for the formation of hard cigarette packs, whereby the blanks are withdrawn successively from the bottom opening of a feedbox and fed on to the outer periphery of a conveyor roller by means of mobile suction heads guided cyclically by crank mechanisms along a route having a portion substantially perpendicular to the bottom opening of the feedbox, and a further portion substantially tangent to the periphery of the conveyor roller and which further route portion is followed by the suction heads at a speed substantially equal to the surface speed of the conveyor roller itself.
