Abstract
An apparatus for continuous bakery products includes a carriage having opposed sealing jaws. Upper and lower webs of wrapping material extend between the jaws of the carriage along a bakery product path. Bakery products to be wrapped are advanced along the bakery product path between the webs of wrapping material and between the initially open jaws of the carriage. The jaws of the carriage are then closed to form transverse seals at the trailing edge of a leading package of bakery products and at the leading edge of a trailing package of bakery products. The carriage is advanced along the bakery product path during the sealing operation so that sealing of the bakery product packages is carried out on a continuous basis. The apparatus for continuous wrapping of bakery products further includes an infeed conveyor having guides for crowding the bakery products into a packaging configuration, a discharge conveyor, apparatus for sealing the lateral edges of the bakery product packages, and apparatus for evacuating air from the bakery product packages.
