A dispenser for dispensing sheet product is provided including a housing that defines an interior configured to accommodate a source of sheet product and an outlet through which the sheet product is dispensed. The dispenser also includes a first roller that is rotatable and disposed in the housing. A portion of the sheet product is designed to be in contact with the first roller prior to being dispensed through the outlet. The dispenser also includes a knife drum that is rotatable and configured to cooperate with the first roller to dispense the sheet product. The knife drum includes a knife configured to cut the sheet product into individual sheets. The dispenser also includes a spring assembly that may be configured to bias the knife drum toward a predetermined position during rotation of the knife drum.

A medium transport apparatus includes a transport roller configured to transport a medium and a roller support portion configured to support the transport roller. The roller support portion includes a support member contacting an outer circumferential surface of the transport roller at two positions thereof in a circumferential direction to support the transport roller, a base member defining a position of the support member, and an intermediary member mediating the support member and the base member. The intermediary member is configured to cause separation between the support member and the base member without moving the support member and the base member.

A retaining member has annular inner and outer circumferential portions, a connection portion, engagement projections, a slit, a grip portion, a first inclined surface, and a second inclined surface. The engagement projections projects from a shaft-facing surface of the inner circumferential surface. The slit is formed in the inner circumferential portion. The grip portion projects outward in the radial direction from an outer rim of the outer circumferential portion. The first inclined surface is formed at an upstream-side end part of the grip portion with respect to a direction of fitting to the shaft to be inclined outward in the radial direction from upstream side to downstream side in the fitting direction. The second inclined surface is formed at a downstream-side end part of the grip portion to be inclined outward in the radial direction from downstream side to upstream side in the fitting direction.

A conveyor device for conveying a single face corrugated web on a bridge is disclosed. The conveyor device includes a lower guide roller, around which the single face corrugated web is guided. The conveyor device further includes an upper pinching and conveyance nip formed by a pair of nip members in pressure contact with one another. At least one of the nip members is motor-driven. The pinching and conveyance nip is configured to pull the single face corrugated web upwards from the lower guide roller.

A one-handed tool for use in application of seam tape or seaming tape. The device has a frame with an upper support with an ergonomic grip, with a finger guard or shield extending across the front of the grip to protect the user's fingers. A primary roller support and a secondary roller support extend downward from upper support. Each roller support comprises a pair of parallel arms extending downward at angles behind and in front of the upper support when in use, supporting a primary roller and a secondary roller, respectively. The primary roller is used to apply pressure to the seaming tape, while the secondary roller is used for stability and to apply additional pressure to the edges of the seaming tape. A retractable blade or knife may be located on one or more roller supports.

An image-forming apparatus for forming an image on a sheet includes an image-forming unit that forms the image on the sheet, and a conveying unit that conveys the sheet on which the image is formed by the image-forming unit. The conveying unit includes a pair of first rollers that discharges the sheet to the outside of the image-forming apparatus and a pair of second rollers that conveys the sheet in a direction in which the sheet is discharged to the outside of the image-forming apparatus and that subsequently switches a conveyance direction of the sheet to an opposite direction to convey the sheet again to the image-forming unit. The pair of the first rollers and the pair of the second rollers partially overlap when viewed in a width direction of the sheet that is perpendicular to the conveyance direction of the sheet.

A method for winding a material sheet, in particular a plastic film, by a winding device, wherein the material sheet is guided from at least one first roller to at least one second roller in a conveying direction. At least one cutting device is arranged between the first roller and the second roller to cut the material sheet into at least two partial sheets. The partial sheets are each wound up into a bobbin in the conveying direction behind the second roller. The at least one first roller and the at least one second roller are each driven by a drive so that the tensile stress in the material sheet or in the partial sheets changes periodically over time in the conveying direction of the material sheet.
