  • Patent number: 4536173
    Abstract: A method of making cups includes forming blanks of a cup sidewall portion, lubricating the upper inside edge of the cup prior to forming the same into a substantially frusto-conical configuration by sealing its opposite edges and the application of tools which curl and then roll the upper edge of the sidewall portion to form the cup rim. The lubricant is applied to the sidewall blank by means of an applicator consisting of an arcuate wick secured between a pair of mounting plates which move the wick into engagement with each blank between the die cutter and the cup forming stations.
