Abstract
A machine for forming a container from a blank of sheet material is provided. The blank includes a reinforcing panel assembly for forming a reinforcing corner assembly. The machine includes a hopper station for storing the blank in a substantially flat configuration and a forming station for forming the blank into the container. The forming station includes an initial forming station that rotates a first portion of the reinforcing panel assembly with respect to a second portion of the reinforcing panel assembly, and a secondary forming station having male and female forming members with shapes corresponding to an interior shape and an exterior shape of the reinforcing corner assembly, respectively. The male and the female forming members are configured to form the reinforcing corner assembly by compressing together the first and second portions of the reinforcing panel assembly.
