ABSTRACT:
Packaging apparatus in which units to be wrapped and flexible packaging material for wrapping the units are fed forward with the units spaced apart in the direction of feed, with a dwell interval between successive feed cycles, and having means for forming a seal across the width of the material between two successive units during each dwell interval. The units are fed forward by conveyor means intermittently driven via a chain and sprocket drive including a crank rotatable about a predetermined axis, means for continuously rotating the crank in one direction about its said axis, a first sprocket secured to the crank with the axis of the first sprocket offset from the crank axis for rotation of the first sprocket about the crank axis without rotation of said first sprocket about its own axis, a second sprocket and a chain trained around said first and second sprockets. The sealing means is operated during the dwell intervals by a similar chain and sprocket drive mechanism.
