In a method for high speed printing of web-based media, a medium is pulled along a media transport path to a pulling transport mechanism. The orientation of the medium with respect to the media transport path is sensed and this orientation is compared to a reference orientation to detect an orientation error. If an orientation error is detected, one or more of the following steps is performed: adjusting a print job for an image to be printed on the web medium; adjusting the transport speed; emitting a communication signal; and stopping the pulling transport mechanism and the image forming unit. It is the insight of the inventor that productivity may be increased by allowing a “tight winding” printing system to start printing at relatively high speed and reduce this speed only when significantly large deviations in the orientation of the web are detected.

An apparatus for holding label stock includes a body including a base and a roll holding area with a roll holding support extending from the base for receiving a roll of label stock. A plurality of rollers are located along a label stock feed path from the roll holding area to a label stock exit zone of the body. The plurality of rollers include a tensioning roller that is movable relative to the base to dissipate tension loads on label stock during label stock movement.

Cladding strip feeders having independent pressure rollers and strip cladding systems with cladding strip feeders having independent pressure rollers are disclosed. A disclosed example cladding strip feeder for a strip cladding system includes: a drive roller to advance a cladding strip along a strip feed path through contact plates; a first pressure roller positioned along the strip feed path opposite a first section of the drive roller; a second pressure roller positioned along the strip feed path opposite a second section of the drive roller; a third pressure roller positioned along the strip feed path opposite a third section of the drive roller; a first pressure adjuster to set a first pressure applied to the cladding strip by the first pressure roller and the first section of the drive roller; a second pressure adjuster to set a second pressure applied to the cladding strip by the second pressure roller and the second section of the drive roller; and a third pressure adjuster to set a third pressure applied to the cladding strip by the third pressure roller and the third section of the drive roller, the first pressure roller, the second pressure roller, and the third pressure roller being configured to apply symmetric pressure across a width of the cladding strip by selectively setting at least one of the second pressure adjuster to apply the second pressure or the third pressure adjuster to apply the third pressure based on the cladding strip having one of at least three incremental strip widths.

At a printer that feeds a continuous paper unwound from a paper sheet supply unit in a sheet-shape to a printing head portion side via a damper portion, and then prints on a label of the continuous paper, in conjunction with an opening and closing operation of the printing head portion of the printing unit, the damper portion opens and closes in a vertical direction.

A print device includes a supply unit, a print unit, a conveyer, a tensioner, a drive unit, a processor, a medium detector, and a memory. The tensioner is configured to apply tension to the medium. The memory stores computer-readable instructions that, when executed by the processor, instruct the processor to perform processes including correction processing, which is repeated a plurality of times, of controlling the drive unit and applying the tension to the medium by the tensioner during a back-and-forth conveyance operation of conveying the medium in the return direction after conveying the medium in the conveyance direction, and detection processing of detecting attributes of the medium, based on the detection result output from the medium detector, during one of the back-and-forth conveyance operations, of the plurality of back-and-forth conveyance operations.

The invention relates to a web guiding device (3) for guiding a material web (2), in particular a film web, with a first and a second frame element (31, 32), which are pivotably mounted on a first spindle (33) in respective first end areas (311, 321), are connected via a rotatably mounted web guide roller (34) in respective second end areas (321, 322) and are connected via a second spindle (35) which is connected to the first spindle (33) by means of a fixing element (37).

An unwinding unit (400) for unwinding a strip (S) of heat sealing material for quadrangular machines (1) comprises a casing (401) adapted to be mounted on a quadrangular machine (1) and a puller (402) operatively associated with the casing (401) and configured to pull the strip (S) relative to the casing (401) along a feed path (P) and in a feed direction (V). A diverter (407) is configured to divert the strip (S) between an initial, preferably horizontal, stretch (P1) of the feed path and a final, substantially vertical stretch (P2) of the feed path, defining a curved, connecting stretch (P3) between the initial stretch and the final stretch. A deformer (413) operatively associated with the casing (401) are configured to make on the strip (5) an extended crease line (414) running along the strip itself starting from the curved stretch (P3) or downstream of the curved stretch (P3), in the feed direction (V) of the strip (S).

The printer has a closed state where the printing head portion and the damper portion are positioned on a position printable on the print mediums, and an open state where the printing head portion and the damper portion are positioned on a position separated from the print mediums. In a case of a transition from the closed state to the open state, the printing head portion and the damper portion behave in conjunction, and in a case of a transition from the open state to the closed state, the damper portion and the printing head portion independently behave.
