Abstract
An automatic sandwich preparation system in which each sandwich is prepared under the control of a computer with condiments as ordered. Shredded lettuce is delivered by an automatic volume measuring mechanism or by a weight responsive delivery system. Condiments such as mayonnaise and mustard are delivered by a volumetric pump and a flexible spreader blade that rotates over a screen above the surface of the bun. In an alternative arrangement, radial dispensing orifices rotate over the bun followed by a flexible spreader blade. In another alternative, the condiments are fed individually through flexible tubes to the bun surface while the positions of each of the delivery orifices are controlled by a common mechanism.
