A dispenser for sheet materials is disclosed. The dispenser includes indexing mechanism and stop release member for dispensing a selected size of sheet material. The indexing mechanism includes an extension spring for dispensing a tail of sheet material from the dispenser. In embodiments, the dispenser includes a drive roller capable of rotating the indexing mechanism when a user removes the sheet material from the dispenser. The drive roller is prevented from rotating when the stop member engages stop release member.

Apparatus for dispensing paper toweling from a roll of paper toweling including roll support structure, a rotatable support drum to transport the paper toweling and cause rotation of the roll of paper toweling, and a rotary damper resisting formation of overspin slack in the paper toweling resulting from a pulling force applied to the paper toweling.

A paper roll end support plug includes a first plug member non-rotatably mounted on a dispenser and a second plug member inserted in the paper roll end and rotatable relative to the first plug member, the plug members being in frictional engagement to prevent overspin of the paper roll during dispensing of paper from the roll.

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 lockout system that is configured to limit use of a rolled web material dispenser assembly to dispense only authorized rolls of web material. The lockout system includes respective first and second mating registration elements that removeably cooperate with one another and provide a rotational cooperation therebetween when engaged with one another. One of the registration elements is non-removeably associated with each authorized roll of web material and the mating registration element is associated with the rolled web material dispenser assembly. The first registration element is supported by the bore of discrete authorized rolls of web material. The corresponding and mating second registration element is supported by the roll dispenser. Mating of the first and second registration elements provides a rotatable linkage that facilitates rotation of the roll relative to the dispenser assembly during the dispense activity.

A sheet material dispenser comprising an operation trigger and a rotatable drum for frictionally engaging sheet material to be dispensed, in which said operation trigger is manually movable in a first direction from a stand-by position to a depressed position, in which said dispenser comprises a return spring which drives said operation trigger in a second direction from said depressed position to said stand-by position, and in which said operation trigger comprises a releasable engagement mechanism which engages said drum and rotates it only when said operation trigger is moved in said second direction.

A dispenser for provision of portions of a tissue web, a retrofit kit for a dispenser, a method for provision of portions of a tissue web, and a method for upgrading a dispenser. The dispenser comprises a first transport arrangement for unused tissue and a second transport arrangement for used tissue, a housing with a dispensing opening through which a tissue portion located between the first transport arrangement and the second transport arrangement protrudes, a detection arrangement comprising at least one sensor unit, preferably comprising a first sensor and a second sensor, for detecting a user change, and a control unit adapted to activate the second transport arrangement when a user change is detected.
