Abstract: A thermoplastic coating is applied to hot glass bottles, such as those in a glass annealing lehr, by transferring the bottles to an overhead conveyor and, while the bottles are suspended therefrom, immersing them in a chamber or tank containing a fluidized bed of thermoplastic resin powder suitable for fluid bed coating. After the bottles have been coated in the fluid bed, they may pass through a further cooling chamber to facilitate their handling. Ultimately, the bottles are delivered to a product delivery station by the overhead conveyor. This conveyor may move in a continuous, i.e., non-intermittent manner, in which case the fluidized bed-containing chamber or tank would also be mounted for longitudinal motion in unison with the overhead conveyor while bottles are immersed therein and for reverse movement, after the bottles have been removed, to return to its starting position. Preferably, the overhead conveyor moves in an intermittent manner and the fluid bed chamber or tank is raised or the bottles lowered in a vertical direction, during the stop period of the intermittent motion of the overhead conveyor, to immerse bottles suspended from the overhead conveyor above the tank. Means for picking up hot bottles, from a lehr for example, and/or for transferring them to the overhead conveyor are also included.
