Abstract
Apparatus and method for assembling a backing card to a plastic blister using strips of double-coated pressure-sensitive adhesive tape. Parallel feed wheels are rotatably mounted for wrapping and transporting tape from tape rolls to an application station from where the tape can be transferred from the wheels to the backing card. Cutting blades are provided for cutting the tape at both ends to form tape strips to be transferred to the backing card. A hingeably mounted tray supports and positions a backing card over the feed wheel surfaces. A pair of rollers are mounted on a carriage and are used to press the backing card onto the surfaces of the feed wheel to transfer tape on the surfaces to the backing card. A blister fixture is further provided for holding a blister to be assembled to a taped backing card. The carriage further supports the rollers for rolling movement over a blister card in the fixture to seal them together.
