Forming and conveying of baked confection shells

Abstract

A machine is provided which includes a pick-up station adapted to receive flat confection discs from a baking machine, and feed them in succession to a rotary wheel at a forming station to lap fold the discs into taco shape. A fixed elongated support rail having a curved upper surface extends generally the length of the conveyor and receives the folded shells thereover so that the shells hang therefrom. An endless belt is coextensive with the support rail and biasingly holds the formed shells to the rail and frictionally drives the shell freely slidingly therealong. A pair of shell leg receiving channels are disposed beneath the support rail, with the channels formed by inner and outer generally parallel walls coextensive with the rail. The inner walls are defined by a support device beneath the rail while the outer walls are formed by plates which are transversely adjustable to thereby control the channel width and shell leg angle. In the embodiment disclosed, the support rail and support device are tubular and fluid flows therethrough to cool and harden the formed shells. The traveling folded shells are subjected to an oil spray which tends to make the shells remain crisp and generally impervious to moisture from a subsequently applied filling. Furthermore, the drive belt is cooled adjacent the shell discharge to counteract belt expansion covered by engagement with the hot baked shells.
