A seaming machine for securing a batten to a roof rib includes a housing (24) having two longitudinal sections (25, 29) which are pivotably secured together about a vertical axis. A cam locking arrangement is provided at the rear of the housings to lock the housing sections (25, 29) together when the machine is positioned on a roof rib. The cam locking arrangement includes a pair of vertically spaced cams (102, 104) which engage a pin (50) disposed in one of the housing sections (25). The seaming machine comprises three pairs of horizontally disposed rollers (52, 54, 56) which progressively bend a flange on a batten against a roof rib, with the rollers engaging the sides of the roof rib to drive the machine along the rib. Vertical pinch rollers (76) are provided between the second and third stage horizontal rollers (54, 56) to crimp the flange on the batten against the roof rib. In this way, a secure and waterproof connection of the batten to the roof rib is provided. |
