sliced is reciprocated past the edge of a circular
rotary knife, being slid along the face of a gauge
plate which is substantially parallel to'the plane
of the edge of the knife and is adjustable in a

The commodity-carrying member of a‘ slicing
machine, usually called the commodity tray or
trough‘, comprises a trough-like structure which
is .mounted for reciprocation on a" slicing ma
chine base to carry themain piece of commodity
past the exposed edgeof the knife. A commod
ity tray is usually provided with a commodity
clamp which may be ‘fed transversely across the
commodity tray toward the plane of the knife
byv means of a spring to force the commidity
