Abstract
A seal belt assembly for a robot mechanism for continuously covering the open top of a cabinet in which an operative device is moved along a rectilinear axis between two opposite sides of the cabinet. The belt assembly provides a belt that is sufficiently strong to sustain the weight of a worker thus avoiding injury to a worker who might accidentally step on the belt, and also provides a sound barrier reducing the noise generated in the cabinet from passing through the ceiling.
