Abstract
Apparatus for placing a coupon or other small sheet onto a predetermined location of moving substrate, such as a carton blank. A coupon supply hooper and a glue station are radially spaced about the path of rotation of vacuum gripping heads mounted on opposite ends of a rotating support arm. The gripping heads are fixed to shafts which are caused to rotate by planetary gears. The gear movement causes the gripping heads to be fully extended when they reach the hopper, the glue station and the moving substrate and to have a composite angular motion enabling the entire bottom surface of the coupon to be parallel to the substrate when the coupon contacts the substrate.
