A device for processing a material web (3) that includes means (2) for conveying the material web in a longitudinal direction (L), wherein both an applied, in particular repeated printed image (9) and a control line (10, 11) extending in the longitudinal direction are configured on the material web (3). The control line (10, 11) has a defined position transverse to the material web (3), and the control line (10, 11) is scanned by means of a sensor (15, 16) in a material web (3) processing step. The control line (3) has a digital code structure in its longitudinal direction (L) that encodes a data set of at least four bits, in particular at least two bytes, of information content.

A winding device includes: a separation unit that separates sheets layered and simultaneously transported; a winding unit that winds one of the sheets separated by the separation unit; and a pressure contact unit that presses the one of the sheets wound by the winding unit from outside of the wound sheet toward the winding unit.

There are included: a plurality of feeding units configured to correspond to respective types of sheets; a detecting unit configured to detect whether or not a sheet is mounted in each of the feeding units; and a display control unit configured to display on a display part a preparation screen for printing on a type of sheet corresponding to one of the feeding units in a case where the type of sheet is mounted in the one of the feeding units whereas no sheet is mounted in any of other feeding units at the time a function including a printing function is selected.

A feed device includes: a feed tray configured to accommodate a roll, in which a medium is rolled in a roll shape, rotatably; a housing configured to support the feed tray installable; and a pull-back mechanism configured to pull back the medium unrolled from the roll in a direction orthogonal to a rotation axis of the roll in conjunction with an outward movement of the feed tray from the housing in the direction orthogonal to the rotation axis of the roll.

An image recording apparatus includes a recording unit, first and second rollers, a guide member, and a cutting unit. The recording unit performs image recording on a sheet conveyed in a conveying direction on a first conveyance path. The first roller is located further downstream than the recording unit in the first conveyance path. The second roller is located further downstream than the first roller in the first conveyance path. The guide member has a guide surface that forms a second conveyance path extending from a connection position of the first conveyance path between the first roller and the second roller. The cutting unit is located between the connection position and the second roller, cuts a sheet, and has a cutter. The guide member changes in posture between a first posture for forming the second conveyance path and a second posture for opening the second conveyance path.

A printing system having an IC tag processing function includes a first medium conveyance section and a second medium conveyance section that convey a medium including a plurality of medium sheets each having an IC tag, an IC tag processor that performs reading and writing processing for the IC tag, a printing section that performs printing on the medium, a slack generator that permits generation of slack of the medium, a calculator that calculates a substantial conveyance speed of the medium by the first medium conveyance section, on a basis of a length of a single medium sheet having the IC tag and time needed by the IC tag processor to process the IC tag of the single medium sheet, and a speed determinator that sets a conveyance speed of the medium by the second medium conveyance section to a speed slower than the substantial conveyance speed.

Provided is a wrapper cutter, including a shell having an axially penetrating hollow structure. A notch extending along an axial direction is further formed in one side edge of the shell, and a cutting knife is fixedly arranged on an inner bottom wall of the notch. Supporting planes arranged axially are further arranged on a sidewall of the shell, can serve as contact planes between the wrapper cutter and a placing plane, and are used to perform positioning, force bearing and supporting in the case of wrapper cutting and assist the wrapper cutter to slide linearly.

A wrapper cutter includes a shell, and the shell includes a second shell and a first shell with a polygonal track structure. The wrapper cutter further includes: an open slot, one side of which is provided with a notch extending along a vertical direction; a cutting knife, fixed on the inner bottom wall of the notch; a rhombic indwelling notch, arranged at one side of the cutting knife; a fixed plate, configured for forcibly bending an introduced wrapper into an arc-shaped surface, so that the wrapper passing through the cut position reaches a maximum stiffness and tension; parallel guideways, a limiting slope for allowing the rolled wrapper to abut against the cutting knife being arranged between the parallel guideways. By adopting a polygonal three-dimensional supporting structure and the fixed plate, the rolled wrapper can reach a maximum tension, and hits the cutting edge to generate a maximum lateral component force.
