摘要： Apparatus and method of forming a tray which includes a bottom panel, four upstanding side panels and corner gussets for sealing and holding the bottom panel end flaps and side flaps in the formed position including means for receiving a stack of precut blanks from which the tray is formed, feeding one at a time, the blanks through a glue station for the deposition of a predetermined glue pattern on the corner gussets, and thereafter folding the blank into a tray in a die and mandrel wherein in successive steps the end flaps are folded, the corner gussets are influenced inward and the side flaps are folded to complete the tray. The die and mandrel assembly serves to hold the tray momentarily after formation to permit the glue to adhere and thereafter functions to strip the tray from the mandrel and hold it in a position satisfactory for removal from the assembly.
