Abstract: To facilitate printing of postage or other images onto media of variable size, an apparatus determines the size of the medium in at least one dimension prior to or during the printing of the image, such that the image to be printed is adjusted based upon the determined size of the medium. The apparatus may be a postage meter, in which case information is received by a data processor concerning the size of a mail piece and the postal value. An initial image is made up of a fixed portion, including postal indicia, and a user-defined variable portion, is then altered in view of this input to provide a final image for printing on the mail piece which fits fully on the mail piece. The alteration effects only the variable portion of the image, which may be truncated, scaled or replaced with a different variable portion.

Abstract: Apparatus for automatically loading paper from a supply roll into a printer. The printer includes a base and a cover hinged to the base. A contoured guide is mounted adjacent to a drive roll to form a paper path that converges from an upper entrance region to a lower exit region in the direction of drive roll rotation. A biased member is mounted in the top cover of the printer and is arranged to move into contact with the drive roll within the entrance region when the cover is closed. In practice, when the cover is open a run of paper from the roll is placed over the entrance region to the paper path. Closing the cover produces rotation of the drive roll and causes the biased member to force the paper into driving contact with roll producing a fold in the front section of the paper supply. The folded section passes through the paper path into a nip formed between the drive roll and pinch rollers whereupon the folded section is advanced through a printing station into a read out station.

Abstract: A storage device for receiving a loop section of a flexible material web (8) moved in a conveying direction (18) between a feed area upstream of the storage device and a discharge area downstream thereof is described, the material web speeds at least periodically differing from one another in the feed area and the discharge area. The speed differences are compensated by a length change of the loop section stored in the storage device. On the feed side the storage device has a first pulling device formed by a suction belt (35, 55) and on the discharge side a separate, second pulling device formed by a parallel suction belt (35, 56). As a result of the parallel suction belts the drawn-in loop section is securely held by vacuum over most of its length, whereas between the pulling devices a tensile force-free loop partial section (4a) is moved to and fro in the store longitudinal direction with substantially no shape change in accordance with the store filling.
