An apparatus for crimping the adjacent side edges of two panels includes a base with first and second crimping members. One of the crimping members is fixed to the base while the other is threaded on a screw member secured to the base. The screw member is rotated by a motor to drive the crimping members together. The apparatus is placed on adjacent panels of the type having preformed mating side edges. The side edge of one panel is in the form of an inverted channel in which the side edge of the other panel fits. The apparatus crimps the side edges so that a downturned leg of the channel is folded onto a portion of the other panel's side edge, thereby crimping the panels together so that a rotary seaming apparatus can be applied to provide a permanent watertight connection. The apparatus is provided with a non-abrasive material to prevent scratching or marring of the panel surfaces.
