ABSTRACT:
Disclosed is an improved safety guard for use with sheet feeding mechanisms which is disposed between the feeding mechanism and the exposed feed roll nip of a mechanism for the processing of the sheet material. The safety guard includes a non-rigid, non-elastic member which prevents an attendant from inadvertently placing his appendages in the exposed nip of feed rolls while not interfering with the passage of the sheet material from the feed mechanism to the feed rolls of the processor. The safety guard adjusts automatically and instantaneously as the width of the sheet material changes to shield the variation in exposure.
