Abstract
A bottom blank maker workstation for a cup making machine is disclosed. The cup making machine is of the type having a rotating turret and a plurality of mandrels arranged to interact with a plurality of workstations. The turret moves each mandrel in a stepwise fashion through the plurality of workstations where a bottom blank and a sidewall blank are formed and attached to one another to create a container. The workstation includes a reciprocable punch and draw that cooperate with an abutment surface and a series of protrusions to impress the lip of the bottom blank with a series of indentations. The indentations promote a better seal to the sidewall blank.
