ABSTRACT The invention relates to filter cups adapted for use in Melitta style coffee makers made of a unitary sheet of filter paper having integral fluted sides flaring outwardly from a stationary bottom and to a method and apparatus for making the same. The apparatus comprises complementary die members adapted to cut and flute the filter discs having central apertures, one of which is affixed to a heating and drying tube having the same diameter as the aperture. A plunger having a stretching head is passed through the other aperture to push the cut and formed filter discs into the heating and drying tube and at the same time to stretch the central portion to form a dish-shaped bottom having integral fluted sides flaring outwardly therefrom.
