Abstract:
A box seaming machine for assembling an oversized box comprising first and second box pieces, each of the box pieces being folded to form top and bottom panels having respective proximal edges joined together at the fold and respective free edges opposite the joined edges, the free edges of the first box piece adapted for being secured to the free edges of the second box piece to define first and second seams of the assembled box, said box seaming machine comprising:(a) a pair of laterally-spaced, opposing drive roller assemblies adapted for movement between an idle position and an operative position, such that in the idle position, the drive roller assemblies are disengaged from the box pieces to enable alignment of the free edges prior to seaming, and in the operative position, the drive roller assemblies frictionally engage the box pieces at respective folds and feed the box pieces downstream for seaming; (b) first and second cylinders for moving respective drive roller assemblies between the idle and operative positions; and (c) first and second seam fasteners downstream of said drive roller assemblies for securing the seams at respective free edges of the first and second box pieces to form an assembled, two-piece box.
