These and other objects of the present invention are achieved by an apparatus for coating product with two colors which includes a first coating section, a second coating section and a means for transferring products from the first to the second sections. The first section includes a feeding and loading station for depositing products onto product holders retained in product carrier plates. The products are advanced to a first dipping station in which a vacuum chamber having the plurality of vacuum tubes engages a plate and inverts and dips the products to coat a first portion of the product. The plates are then advanced to a first rotating station where another vacuum chamber and vacuum tube device engages the plates and rotates the plates one revolution for spreading the coating over that first portion. The plates are advanced to an elevator where they are raised incrementally to a dryer that extends over the first section of the coating apparatus. The plates are transferred into the dryer where they traverse through the dryer in a controlled manner for curing the coating applied to the first portion. The plates are transferred to a down elevator and returned to the conveyor where they are advanced to a side to side transfer apparatus. The transfer apparatus transfers the products to the second section of the coating apparatus in such a manner to expose on carrier plates the uncoated portion of the products. The plates are then advanced to identical dipping and rotating stations as in the first section and then transferred by an elevator up to a second dryer located above the conveyor in the second section. The plates traverse the second dryer and are returned to the second conveyor by a down elevator where the plates are advanced to an unloading and discharge apparatus. the empty plates are then advanced to the side to side transfer where they are recycled for future use in the apparatus.
