摘要： A sheet conveying apparatus includes first and second roller members fixed to a rotatable shaft, a first follower roller that cooperates with the first roller member to form a conveying nip, and a second follower roller that cooperates with the second roller member to form a conveying nip. The first and second roller members have outer periphery cut-away parts and the first and second follower rollers are moveably supported and can be biased to home positions. If the first roller member cut-away part faces the first follower roller, the first follower roller is biased to move toward a home position while the nip of the second roller member nips and conveys a sheet. If the second roller member cut-away part faces the second follower roller, the second follower roller is biased to move toward a home position while the nip of the first roller member nips and conveys a sheet.

摘要： For the transport of widths or sheets of paper, a roller is disclosed which comprises a bushing (1), which is surrounded by an elastic cylindrical casing. The bushing has a coaxial bore into which a shaft (3) is pressed. The bore of the bushing (1), which limits the clearance is provided with radially inwardly extending protrusions (2), which are evenly angularly spaced about the bore and which extend in the axial direction. When pressing the shaft (3) into the bushing (1) of the roller body, the protrusions (2) are forced to move radially outwards and effect a rotationally secure connection of the roller body to the shaft (3). Any expansion of the bushing will be even and while possibly enlarging the casing will not interfere with concentricity.

摘要： An apparatus (10) for conveying flexible sheet-like products wherein a plurality of conveying elements (12) are arranged one behind the other on a rotatable support member in a circular array, and each conveying element comprises a roller segment (24), which is driven continuously in the direction of rotation (D), and a mating element (26), which interacts with the roller segment. In the product receiving region (14), a recess section (44) of the respective roller segment (24) forms, with the mating element (26), an introduction gap (48), of which the leading end is closed. The forward position of the recess section (44) forms a stop (62) for engaging the leading edge (52) of the fed product (19). At about the same time as the leading edge (52) comes into contact with the stop (62), a lateral-surface section (46) following the recess section (44) forms, together with the mating element (26), a conveying gap (54) in which the product (19) is retained in order to be transported further through the conveying element (12).

摘要： A paper feeding device includes conveyor rollers including top rollers and bottom rollers which rotate in the same direction and disposed respectively on two shafts in alternate positions. Timing rollers are provided on the down stream side of the conveyor rollers. The center-to-center distance between the two shafts is somewhat smaller than the sum of the radii of the top and bottom rollers. A recess is provided on each of the top rollers, so that the recess faces the direction of the circumference of the bottom rollers, when the forward end of the original sheet conveyed to the timing rollers by conveyor rollers abuts the timing rollers.
