Seaming apparatus for joining the adjacent side edge portions of two adjacent panels to provide a continuous seam is disclosed. The apparatus includes a support base having a main base portion and a movable base portion. The movable base portion is pivotally connected to the main base portion for pivotal movement about an axis between a first positon and a second position. Sets of opposed motor driven seaming rollers are mounted on the base with one roller of each set being rotatably mounted on the movable base portion and the other roller of each set rotatably mounted on the main base portion. The rollers of each set are oppositely disposed and have peripheral surfaces arranged to engage the adjacent side edge portions of the adjacent panels. A drive train driven by a motor and including a drive gear for each driven roller is provided for rotating the driven rollers to move the apparatus along the adjacent side edge portions. Actuating means is mounted off one side of the movable base portion for pivotally moving the movable base toward and away from the main base between the first position and the second position. When in the first position, the axes of the rollers of each set of driven rollers will be substantially parallel. When in the second position, these axes will form an included angle of less than 30 degrees which maintains the drive gears of each set of rollers in meshing engagement. One seamer has four sets and the other three sets of seaming rollers. The latter form uses a cam surface to direct one of the rollers of one set in a selected path to move the roller to a horizontal position and to clear the formed seam. |
