The invention provides a paper conveyance mechanism capable of curl correction of paper drawn out from roll paper according to the intensity of curl. The paper conveyance mechanism comprises an ironing part for correcting paper curl which is brought into contact with an outer surface of the paper, a pressing part which presses the paper from one side to bend the paper at the ironing part, and an arm engaged with an outer circumferential surface of the roll paper to be operated according to a change in a roll diameter. An upstream-side pressing part is moved from the one side toward the other side in association with an operation of the arm during at least part of a period of the operation of the arm to reduce an ironing angle formed in the paper bent at the ironing part according to a decrease in the roll diameter.

An accumulation device is provided with a loading unit, a tensioning unit, an accumulation unit, and unloading unit and a controller. The tensioning unit comprises multiple fixed rollers capable of rolling, and movable rollers capable of rolling and arranged so as to be capable of moving with respect to the fixed rollers. Substrates are conveyed so as to move back and forth alternately between the fixed rollers and the movable rollers in a wrapped state, and a prescribed tensile force is applied to the substrates by a force acting on the moveable rollers in the direction away from the fixed rollers. The controller performs control so as to maintain the positions of the movable rollers in the tensioning unit constant.

A system and method for controlling curl in multi-layer webs. The method can include providing a coated web, curing the coating to form a multi-layer web, and stretching the web during curing of the coating. Some coatings shrink at least partially when cured such that curing the coating induces a strain in the multi-layer web. Stretching the web occurs during curing to induce an opposing strain that at least partially counteracts the strain induced by curing to form a multi-layer web having a desired curvature. The system can include a curing section configured to cure the coating, and can further include a web stretching section, which can be located proximate the curing section and can be substantially coincident with the curing section, such that the web is stretched while the coating is cured.

An image forming apparatus includes the following. An image carrier carries a toner image. A transfer unit transfers a toner image held by the image carrier onto a sheet. A controller controls a relation of a position between the image carrier and the sheet so that the sheet continues to come into contact with the image carrier from a position where a distance from a transfer nip is within a predetermined range when the sheet enters the transfer nip during an image forming job. The transfer nip is formed by the image carrier and the transfer unit.
