A roller for a sheet product dispenser includes a roller shaft, a roller frame molded onto the roller shaft, and a plurality of flexible rubber portions overmolded onto the roller frame and spaced along a length of the roller frame. The rubber portions are configured to contact a sheet product for dispensing from the sheet product dispenser. A dispensing mechanism for a sheet product dispenser includes a chassis and a roller positioned within and coupled to the chassis.

Automated sheet product dispenser

A dispensing mechanism for a sheet product dispenser includes a chassis, a roller positioned within and coupled to the chassis, and a spring configured to bias the roller into contact with a sheet product. Another dispensing mechanism for a sheet product dispenser includes a chassis, a roller positioned within the chassis, a pair of plugs, and a pair of springs. The roller is coupled to the chassis via the plugs, and the springs are configured to bias the roller into contact with a sheet product. Still another dispensing mechanism for a sheet product dispenser includes a chassis, a first roller positioned within and coupled to the chassis, a second roller positioned within and coupled to the chassis, and a spring configured to bias the first roller toward the second roller and into contact with a sheet product.

The described system and method allows for the control of inflation and deflation of air mattresses such that fast and accurate deflate times and satisfaction of consumer expectations may be achieved. A combination of empirically-derived deflate profiles, corrected dynamic measurements, and static measurements may be used to achieve fast and accurate deflation to user-defined target pressures. Additionally, a marketing routine that invokes simulated deflation or simulated inflation when deflation or inflation is not necessary but a user is expecting deflation or inflation, respectively, may be used to better satisfy the user's expectations.

A sheet product dispenser includes a sheet product feed mechanism coupled to a DC stepper motor, the mechanism moving a sheet product out of the dispenser during a dispense cycle; and a control unit controlling the DC stepper motor to move the sheet product with a gradually increasing acceleration during a portion of the dispense cycle.
