ABSTRACT:
A floor mat apparatus comprises a length of synthetic plastic material having a high plasticizer content, and therefore having a tacky surface to collect dirt and bacteria, trained about rollers one of which is driven by a motor to bring fresh portions of the mat to the upper stretch between rollers across which people walk to a clean-room area. Portions of the mat leaving the upper stretch are washed and dried before returning to the upper stretch.
