Forming Corrugated Trays

In horizontal tray formers, otherwise known as tray makers, the corrugated sheet is fed into the area above the die or forming tool. Hot melt is applied during the feed process or when the sheet is stationary. A plunger presses the board down, pushing the box into the die or forming tool to make it into the proper shape. Outside guides are used on part of the die to force the corrugated around the plunger surface, while the outer flaps are folded against the inner flaps to form the tray. Dots, or small lines of hot melt are usually used to secure the corner flaps in place.
