ABSTRACT:
A fitment attachment apparatus installed at a station along a filler line is substantially completely mounted on a single casting attached to the bed of the machine. As an open upper end, apertured panel carton is conveyed to the station, a rotary anvil having spuds on which fitments are applied lowers a fitment inside the carton. The anvil is moved axially so that the spout end of the fitment extends out through the aperture in the carton panel and a peripheral flange on the opposite end of the fitment engages the inside of the aperture panel. The anvil shaft carries a driven sprocket on one end which is connected by a side-flex chain to a drive sprocket which turns in timed relation to the intermittent carton conveyor chain. The sleeve on which the anvil is mounted is indexed into precise angular position by an apertured collar fixed to the anvil sleeve mating with a stationary pen. Hence the fitment is accurately located in line with the carton despite flexing of the drive chain.
