A sheet product dispenser is provided including a housing including a roll holder configured to receive a product roll, a dispensing mechanism configured to dispense a portion of the sheet product from the product roll, a sensor configured to emit a signal toward the product roll and receive a reflection of the signal from a surface of the product roll, and a controller. The controller is configured to receive an indication of replacement of the product roll, determine a time-of-flight of the signal, and determine an expected time-of-flight (or corresponding distance of travel) of a theoretical signal to a theoretical full product roll. The controller is further configured to compare the time-of-flight (or a corresponding distance of travel) of the signal to the product roll to the expected time-of-flight or distance, and adjust a product depletion curve based on the comparison.

A sheet product dispenser for dispensing sheet product from a roll of sheet product having a sealed tail is provided. The sheet product dispenser includes a roll interface configured to engage and at least partially support the roll of sheet product, the roll interface including a separating member configured to engage and unseal the sealed tail; a feed roller assembly configured to dispense sheet product from the roll of sheet product, the feed roller assembly including a feed roller configured to engage and at least partially support the roll of sheet product; and a controller operable to initiate driving of the feed roller and rotation of the roll of sheet product such that the sealed tail is unsealed by engaging the separating member. A related method of automatically loading a roll of sheet product having a sealed tail in a sheet product dispenser also is provided.

A paper towel dispenser for dispensing paper towels from a continuous roll of paper towels includes a dispensing body configured to dispense paper towels. The dispensing body has an upstream inlet configured to receive the paper towels and a downstream outlet configured to dispense the paper towel. The dispensing body defines a cutout that extends between the upstream inlet and the downstream outlet through which the paper towels are moved to load the paper towels into the dispensing body. The dispenser includes a closure device configured to be received in the cutout and restrain the paper towels in the dispensing body.

Improvements to sheet product dispensers configured to hold multiple product rolls are provided herein. An example sheet product dispenser comprises a housing defining a dispensing position and a reserve position. The housing is configured to hold a first roll of sheet product in the dispensing position and a second roll of sheet product in the reserve position, where a user can receive a portion of the first roll of sheet product that is in the dispensing position. The sheet product dispenser includes a roll replacement feature that is configured to enable installation of a replacement roll of sheet product into the reserve position. The sheet product dispenser includes a restrictive access feature configured to prevent installation of the replacement roll of sheet product directly into the dispensing position in an instance in which the roll replacement feature enables installation of the replacement roll of sheet product in the reserve position.

A towel dispenser includes a housing mounted to a wall and defining an interior space for receiving toweling comprising a roll of towels, the interior space comprising a curved surface configured to receive the roll of towels in floating engagement therewith such that the roll of towels rolls and slides on the curved surface during unwinding of the roll of towels. The towel dispenser further includes a loading door configured to rotate relative to the main body, when the main body is mounted to a wall, between a closed position in which the loading door extends over a top of and closes off the interior space of the main body in which toweling is received, and an open position, in which the housing is configured to receive toweling therein without obstruction by the loading door, with the loading door extending upwardly above and over a top of the housing.

A towel dispenser includes a housing for receiving toweling. The housing includes a main body; a loading door that is configured to rotate relative to the main body between a closed position and an open position; and a guide system that includes a first roller attached to the main body and a second roller attached to the loading door. The towel dispenser may include a motor for driving dispensing of the toweling from the housing and an associated sensor. The towel dispenser can be mounted to an underside of a cabinet. In an aspect, the front wall of the main body and a lip of the loading door collectively define a gap to which the guiding system guides the toweling and through which towels are dispensed when the loading door is in the closed position.

A drop assembly for a paper product dispenser is provided that transitions an upper carriage for a second roll of paper product into a primary or first position after depletion of a first or primary roll of paper product without user intervention. The drop assembly transitions the upper carriage into approximately the same position previously occupied by the lower carriage, allowing a small aperture in a front face of a dispenser to be used. Additionally, the drop assembly can include a reset connection to transition the drop assembly back to the firsts position upon opening of a dispenser front face.

Dispenser for dispensing web material from a roll, the dispenser including a housing and a spindle intended to rotatably support a roll of web material during dispensing. The spindle is movable between a loading position and a dispensing position. The dispenser further includes a deflecting member being movable between a protruding position protruding towards the spindle in dispensing position and a retracted position retracted into the housing away from the spindle in dispensing position. The deflecting member is connected to a blocking member moving in response to the movement of the deflecting member.

A dispensing assembly is disclosed herein. The dispensing assembly includes a housing comprising a plurality of side panels that together define a compartment; a self-contained cartridge for dispensing a paper product, the self-contained cartridge being removably received in the compartment of the housing; and an actuation subassembly being disposed in the housing, the actuation subassembly configured to advance the paper product disposed in the self-contained cartridge.

A dispenser for dispensing sheet material from one or more rolls of sheet material is provided. The dispenser includes a housing having an interior volume and a module disposed within the housing including a dispensing mechanism. The dispenser includes a transfer assembly having a rear transfer roller and a front transfer roller disposed on a transfer arm. The transfer arm is disposed in one or more walls of the module via a slot. The transfer arm is configured to be placed in an operating position or a loading position. When in the loading position, the transfer arm extends into a second portion of the slot to provide greater clearance between the front transfer roller and the drive roller to facilitate loading of the sheet material. A transfer assembly is also disclosed having a rear transfer roller disposed in a slot disposed in a second portion of the transfer arm. When in loading position, the rear transfer roller extends into the second portion of the slot to provide greater clearance between the front transfer roller and the drive roller to facilitate loading of the sheet material.
