1. A dispenser, comprising:
- a housing body;
a housing cover; and
a feed mechanism comprising a drive roller and a pressure roller,wherein said drive roller and said pressure roller form a nip therebetween, said housing cover is movable with respect to said housing body for opening and closing said housing cover, said housing cover is operably connected to at least one of said pressure roller or said drive roller such that movement of said housing cover from a closed position towards an open position moves said pressure roller relatively away from said drive roller to thereby open said nip, said housing cover is operably connected to said pressure roller by at least one rotatable linkage, said linkage is connected at one end to said housing cover and at the other end to at least one end portion of said pressure roller or to a means for support for said pressure roller, or to a movable carrier in which said pressure roller is rotatably mounted, at least one of said pressure roller or said means for support for said pressure roller, or said movable carrier being supported in said housing body.

Abstract
A dispenser for sheet material such as paper towel, having a housing body and a housing cover. A feed mechanism in the dispenser includes a drive roller and a pressure roller forming a nip therebetween. Movement of the housing cover from a closed position towards an open position moves the pressure roller relatively away from the drive roller to open the nip. The reverse occurs during closing the cover. This allows easy access to the space between the rollers when adding a new supply of sheet material or when removing sheet material jams. A method for loading a dispenser is also included.

11. A dispenser, comprising:
-
a housing body; a housing cover; and a feed mechanism comprising a drive roller and a pressure roller, wherein said drive roller and said pressure roller form a nip therebetween, said housing cover is movable with respect to said housing body for opening and closing said housing cover, said housing cover is operably connected to at least one of said pressure roller or said drive roller such that movement of said housing cover from a closed position towards an open position moves said pressure roller relatively away from said drive roller to thereby open said nip, said housing cover has a guide surface thereon projecting inwardly from said housing cover towards an interior of said housing body, said guide surface being slidably movable against a further surface, said further surface is arranged on a movable element, and said movable element, in at least one position thereof, is operably connected to said pressure roller such that movement of said housing cover towards a closed position causes sliding engagement of said guide surface with said further surface to thereby cause said pressure roller to move closer to said drive roller, at least during part of the movement of said housing cover towards its closed position. - View Dependent Claims (12, 13, 14)

15. A method of loading a dispenser comprising a housing body, a housing cover and a feed mechanism, said feed mechanism comprising a drive roller and a pressure roller, said drive roller and said pressure roller forming a nip therebetween and wherein said housing cover is movable with respect to said housing body for opening and closing said housing cover, the method comprising:
-
opening the housing cover to allow access to a supply of sheet material to be used in the dispenser located in a supply storage location thereof; inserting a leading edge portion of said sheet material between the rollers in an open condition of said nip, in which open condition said drive roller and said pressure roller have been moved relatively away from each other by a distance equal to at least twice the thickness of said sheet material; and inserting said leading edge portion into said nip, without rotation of said drive roller or said pressure roller being required, wherein said pressure roller is moved relatively away from said drive roller to open said nip by means of a rotatable operative connection between said housing cover and at least one of said pressure roller or said drive roller, and wherein said nip is closable by said rotatable operative connection, movement of said housing cover from a closed position towards an open position moves said pressure roller relatively away from said drive roller, and the nip is closed so as to clamp sheet material in the nip. - View Dependent Claims (16, 17, 18, 19, 20)
