Electronic towel dispensers and methods of operation disclosed. In one embodiment, a towel dispenser for dispensing web material from a roll of web material may comprise a housing comprising a back panel and a front cover and having an internal volume so as to retain at least one roll of web material therein, an electronically powered dispensing mechanism contained within the housing for dispensing web material from the roll of web material upon actuation of said dispensing mechanism, a tear bar disposed within the housing, the tear bar comprising a tear bar back edge and a tear bar cutting edge, and a tear bar actuator coupled to the tear bar and configured to move the tear bar between a tear bar primary position and a tear bar secondary position.

A non-drip hygiene dispenser for dispensing a wipe paper-towel while keeping a clean and sterile working area comprises (a) a wipe paper-towel, (b) at least one reservoir containing liquid, (c) a first stream of compressed air, (d) a second stream of compressed air, an anti-dripping nozzle, (e) rolling means, and (f) cutting means. The anti-dripping nozzle further comprises activating means and a dispensing tip. The activating means comprises a retractable anti-drip needle backed by a spring. The spring retracts backwards when compressed air of the first stream of compressed air presses the spring, thus retracts the anti-drip needle, and thus, unblocks the dispensing tip to allow liquid from the at least one reservoir to flow through the dispensing tip. When the compressed air pressing the spring is released, the retractable anti-drip needle returns to its original place, blocking the dispensing tip to block the passage of liquid remained in the dispenser immediately upon shut off of the dispenser, thus, to avoid undesired dripping. The second stream of compressed air entering the anti-dripping nozzle mixes with the sprayed liquid in order to form a foggy environment around the wipe paper-towel.

A paper dispenser includes a paper input area and a paper output area; the paper input area including a holder for a paper roll and including a paper input unit provided to displace paper from the paper roll towards the paper output area, the paper output area including a paper output unit which is adapted to dispense paper to an outside of the dispenser, the dispenser further including a paper cutting unit arranged between the paper input unit and a paper output unit, which paper cutting unit is adapted for cutting the paper, wherein the paper output unit is operationally connected to the paper input unit to dispense the paper at a dispensing speed that is at least as large as a displacing speed of the paper input unit.

A dispenser having a feed roller that at least partially engages sheet material to facilitate dispensing thereof, and a cutting mechanism disposed within a chamber defined by a body of the feed roller. The cutting mechanism including a cutting blade and at least one movable support connected thereto. The at least one support further is operatively connected to the body of the feed roller and is actuated with rotation thereof to move the cutting blade into and out from one or more openings defined along the body of the feed roller to at least partially cut or perforate a selected portion of the sheet material as the sheet material is dispensed.

A roll paper holder includes: a blade member having a blade provided at an end of a base, a press projection provided at the other end of the base, and a convex portion provided on an upper surface of the base; a blade-member-storing case pivotally supporting the convex portion of the blade member; and a holder body to which a roll paper is attachable, in which the blade-member-storing case is mounted on an upper surface of the holder body with a base end pivotally supported by the holder body, and the blade-member-storing case has a cutout in a side thereof, the cutout being curved from a front end of the side to a lower portion of the side close to the base end of the blade-member-storing case.

A wiping material dispenser in the form of a spool from which the material can be unwound in a strip. The dispenser includes a housing and a cutting system for cutting the strip pulled manually by a user. The cutting system includes a flexible blade and at least one tooth mounted on a front side of the housing. The flexible blade includes at least one slot positioned opposite the at least one tooth. The flexible blade can be deformed under the pressure of the strip, when a user pulls on the strip from the front side of the housing, so that the at least one tooth protrudes through the at least one slot, comes into contact with the strip pressed onto the flexible blade and tears the strip at a pre-cut line.

A dispenser having a feed roller that at least partially engages sheet material to facilitate dispensing thereof, and a cutting mechanism disposed within a chamber defined by a body of the feed roller. The cutting mechanism including a cutting blade and at least one movable support connected thereto. The at least one support further is operatively connected to the body of the feed roller and is actuated with rotation thereof to move the cutting blade into and out from one or more openings defined along the body of the feed roller to at least partially cut or perforate a selected portion of the sheet material as the sheet material is dispensed.

In example, a sheet material dispenser can include a feed roller configured to engage and move the sheet material along a discharge path for dispensing thereof, and a manual dispensing assembly in communication with the feed roller. The manual dispensing assembly can include an engagement portion operatively coupled to the feed roller body for engagement by a user to rotate the feed roller to facilitate dispensing of the sheet material, and an integrated gear clutch configured to control movement of the engagement portion or the feed roller. Other examples also are described.

A paper dispenser includes a paper input area and a paper output area; the paper input area including a holder for a paper roll and including a paper input unit provided to displace paper from the paper roll towards the paper output area, the paper output area including a paper output unit which is adapted to dispense paper to an outside of the dispenser, the dispenser further including a paper cutting unit arranged between the paper input unit and a paper output unit, which paper cutting unit is adapted for cutting the paper, wherein the paper output unit is operationally connected to the paper input unit to dispense the paper at a dispensing speed that is at least as large as a displacing speed of the paper input unit.

A paper toweling dispenser for dispensing paper toweling from a roll of paper toweling including a top roller located between the paper roll and the drum of the dispenser which moves in radial cams along the outer circumference of the drum as a pulling force is applied to the leading edge of the paper toweling by a user.
