An image forming device with a collapsible paper guide is provided. The image forming device includes a casing, a first tray structure and a paper guide. A medium gateway opening is formed on the casing. The first tray structure is disposed on the casing and adjacent to the medium gateway opening. The paper guide includes a first base disposed on the first tray structure and a first guiding component pivotally connected to the first base. The paper guide is switchable relative to the first tray structure between a used position and a stored position. A first included angle included between the first guiding component and the first base is less than 90 degrees when the paper guide is located at the used position, so that the first guiding component can be interfered and driven to pivotally fold for preventing the paper guide from being broken or damaged.

The present invention is a method for selectively machine directionally stretching a predetermined section of a pre-combined web material of varying material width by running the web over stretching rolls operated at a speed differential

A paper transport device includes a transport mechanism that transports paper to which an image is transferred to a fixing device while sucking the paper and a switching mechanism that switches between suction regions in a width direction of the transport mechanism, which corresponds to a width direction of the paper, according to a size of the paper.

A removable flexible jacket for use in a printing press having a transfer cylinder for transferring a freshly printed substrate. The removable flexible jacket comprises a coated beaded sheet adhered to an plastic sheet, wherein a plurality of images are printed on a downwards facing side of the plastic sheet and visible through the upwards facing side of the coated beaded sheet, wherein the plurality of images provide indications of how to cut the sheet to size to fit different sized transfer cylinders and indications of zones of the flexible jacket to promote selective cleaning of the flexible jacket during use in transferring printed substrates.

The machine (1) comprises: an unwinding section (3) of parent reels (Ba, Bb) of web material (Na, Nb); a cutting station (13), comprising a plurality of cutting members (201, 203) to divide the web material (Na, Nb) into longitudinal strips (S); a plurality of winding stations (15); in each winding station (15), a guide arm (31) to guide the longitudinal strip (S), adjustable parallel to the rotation axis (C-C) of the winding mandrel (51). The cutting station (13) comprises sensor members (213, 214) to detect the position of the cutting members (201, 203). A control unit (216) is interfaced with the sensor members (213, 214) of the cutting station (13) and the positioning actuators (27), to position the guide arms (31) parallel to the rotation axis (C-C) of the respective winding mandrel (51) as a function of the position of the corresponding cutting member (201, 203).

A sheet processing apparatus capable of discharging even a lateral displacement uncorrectable sheet onto a discharge tray without collision with an alignment plate. A finisher conveys a sheet along a conveying path. A shift unit corrects a lateral displacement of the sheet based on a result of detection by a lateral displacement detection sensor. Sheets discharged via the conveying path are stacked on a discharge tray. A pair of alignment plates disposed above the stacking tray are lowered and are moved between a standby position and an alignment position to be brought into abutment with respective opposite edges of the discharged sheet in the alignment position. A finisher controller makes a distance between the alignment plates in a standby position different according to a sheet type, even when a size of the sheet in the width direction is the same.
