An apparatus and method for molding food-grade containers from a strip of paper material is provided. The apparatus includes a stationary die-holder plate, and a die-holder plate which is movable with respect to it between an opened position and a closed position. The stationary die-holder plate includes a respective stationary die half and the movable die-holder plate include a respective mobile die half. In the closed position, the die halves cooperate to define an impression corresponding to a container provided with a bottom, a side wall, and a substantially flat perimeter portion cantileverly extending from the side wall. A curling member, a permanent pleating member and a cutting blade are concentrically provided around the mobile die half and sequentially arranged from the inside to the outside thereof. Similarly, a counter curling member, a counter permanent pleating member and a counter cutting blade are concentrically arranged around the stationary die half. |
