Seaming apparatus has two sets of opposed seaming rollers (21, 22 and 23, 24) rotatably mounted on a base (20) and positioned so that the sets successively engage and track on opposite side edge portions of the panel and bend a terminal side section (17) under to form a continuous seam. A drive motor (111) and drive train (81, 82, 83, 84, 113) between the motor and rollers provides a direct positive drive for each roller. One roller of each set is mounted on a slidable base portion (27) that provides for varying the roller spacing and is removable from a main base (26) and reinsertable thereinto along the opposite side to reverse roller positions. Modified forms of seaming apparatus have two spaced slide bores (335) in blocks (333) sandwiched between spaced plates (331, 332) with thrust pins 341 slidable in the bores for guided movement of two base portions (326, 327). A dual clevis (370) on a single actuator arm (363) and detents (382) on the inboard base portion with springs (350) between the base portions move and lock the base portions. Pin (401) and slot (402) couplings are disclosed for interchanging the outboard rollers or a duplicate set of leading rollers (531 and 532) is used on the opposite ends of the base portions for reversing the direction of the seaming apparatus.

Seaming apparatus for joining together adjacent outturned and inturned side edge portions of two adjacent panels along a continuous connecting seam when moved in either direction along the seam, the outturned side edge portion including an upstanding side section, outturned lateral flange sections and a downturned terminal section forming an exterior inverted channel prior to seaming, the inturned side edge portion being disposed within said outturned side edge portion and including an upstanding side section and an inturned lateral flange section extending along said outturned lateral flange section, said seaming apparatus comprising: first and second sets of opposed seaming rollers rotatably mounted on a supporting means including a first base portion and a second base portion, said sets of seaming rollers having peripheral surface portions arranged to simultaneously bear against oppositely facing surface portions of at least one of said side edge portions, said first and second sets being spaced from one another along said base portions to successively engage opposite surfaces of said oppositely facing surface portions to track thereon and bend said terminal section back under said inturned lateral flange section to form a continuous connecting seam as said rollers are moved along said panels, one roller of each set being supported on said first base portion, said second base portion supporting the other roller of each said set, said first and second base portions being joined for guided movement toward and away from one another between a first position for seaming and a second position while maintaining the axes of the rollers of each set substantially parallel during said movement of said rollers; means for moving said base portions between said positions and having means for releasably locking said base portions in said second position; and drive means for simultaneously rotating each of said seaming rollers to move said rollers and said supporting means along said two adjacent panels.
