An apparatus for forming a tray from a blank of sheet material is provided. The apparatus includes a platen configured to move along a path between a first position and a second position to drive the blank downstream from the first position and a first folding arm configured to fold an outside corner support member of the blank to form the blank into a partially formed tray including at least a portion of the outside corner support member being substantially parallel to the bottom panel. The apparatus further includes a fixed plate and a movable plate spaced from and movable with respect to the fixed plate. The fixed plate and the movable plate define a passage therebetween. The fixed plate guides the outside corner support member through the passage to a position adjacent a side panel and/or an end panel.

An apparatus for forming a tray from a blank of sheet material, the blank including a bottom panel, a pair of opposing side panels extending from side edges of the bottom panel, a pair of opposing end panels extending from end edges of the bottom panel, and an outside corner support member extending from a top edge of each side panel of the pair of side panels, the apparatus comprising: a platen configured to move between a first position proximate and in spaced relation to the bottom panel and a second position in contact with the bottom panel;forming rails configured to rotate the pair of side panels and the pair of end panels with respect to the bottom panel as the platen moves from the first position to the second position;a plurality of moveable plates configured to contact a first portion of a respective outside corner support member; anda plurality of fixed plates each spaced from an adjacent moveable plate to define a passage between each fixed plate and the adjacent moveable plate, the fixed plates configured to guide a side edge of an adjacent outside corner support member as the adjacent outside corner support member is rotated through the passage to form the tray. 7. An apparatus in accordance with claim 6, wherein each outside corner support member includes a top wall portion connected to the top edge of each side panel, the apparatus further comprising folding arms configured to rotate the top wall portions with respect to an associated side panel such that each side edge of the outside corner support members is adjacent to one of the fixed plates. 8. An apparatus in accordance with claim 6, wherein each outside corner support member includes a top wall portion connected to the top edge of each side panel and an end fold portion extending from an end edge of the top wall portion, the apparatus further comprising folding arms configured to rotate the end fold portions with respect to the top wall portions, the end fold portions rotated through each passage to be positioned adjacent a respective end panel of the pair of end panels. 9. An apparatus in accordance with claim 8, wherein each outside corner support member further includes a side fold portion extending from a side edge of the end fold portion, the moveable plates are configured to guide the side fold portions to be adjacent an adjacent side panel of the pair of side panels as the end fold portions are rotated by the folding arms. 10. An apparatus in accordance with claim 8, wherein the fixed plates are configured to guide the end fold portions as the end fold portions are rotated by the folding arms. 11. An apparatus in accordance with claim 6, wherein each fixed plate comprises two opposing edges and two opposing faces, a first edge of the two edges proximate to one of the end panels and a first face of the two faces configured to guide an adjacent end fold portion into overlying relationship with the end panel. 12. An apparatus in accordance with claim 11, wherein the first face is substantially perpendicular to the end panel proximate the first edge. 13. An apparatus in accordance with claim 6 further comprising four passages, each passage of the four passage defined at one corner of the blank. 14. An apparatus in accordance with claim 13 further comprising four folding arms each adjacent one passage of the four passages, each folding arm of the four folding arms configured to rotate one of the outside corner support members through one of the four passages into at least partially overlying relationship with an adjacent end panel of the pair of end panels. 15. A method for forming a tray from a blank of sheet material using a machine, the blank including a bottom panel, a pair of opposing side panels extending from side edges of the bottom panel, a pair of opposing end panels extending from end edges of the bottom panel, and an outside corner support member extending from a top edge of each side panel of the pair of side panels, the machine including a platen, a first folding arm, a fixed plate, and a movable plate, the method comprising: driving the blank downstream from a first position toward a second position using the platen;folding the outside corner support member of the blank using the first folding arm to form the blank into a partially formed tray, the partially formed tray including at least a portion of the outside corner support member being substantially parallel to the bottom panel; andguiding the outside corner support member of the partially formed tray through a passage defined between the fixed plate and the moveable plate to a position adjacent at least one of the side panel and the end panel to form a tray wall of the tray using the fixed plate, wherein the movable plate is spaced from and movable with respect to the fixed plate. 16.
