The present invention relates to a device for displaying the state of a dry non-woven fabric roll for a wet towel manufacturing apparatus, which can allow a user to readily inspect the dry non-woven fabric roll in the wet towel manufacturing apparatus, which can offhand supply a disposable wet towel formed by cutting the dry non-woven fabric of a dry non-woven fabric roll, which is mounted around a bobbin and accommodated in a cavity formed inside a frame, into a given length, impregnating the cut dry non-woven fabric with water, and rolling or folding the impregnated dry non-woven fabric into several layers while feeding the dry non-woven fabric roll. The device for displaying the state of a dry non-woven fabric roll comprises pushing member, a sensing member, and a display unit. The pushing member is installed in such a manner that one side thereof abuts against an outer circumference of any one of the dry non-woven fabric roll and the bobbin, the pushing member being adapted to permit the dry non-woven fabric roll and the bobbin to be deviated from their initial position by a predetermined elastic force thereof, which is exerted toward the dry non-woven fabric roll and the bobbin, when the dry non-woven fabric is completely consumed. The sensing member is operated by the pushing member for generating an electric signal when the dry non-woven fabric roll and the bobbin are deviated from their initial position by the pushing member. The display unit is adapted to externally display the state where the dry non-woven fabric roll and the bobbin are deviated from their initial position, when the electric signal is generated from the sensing member. |
