Abstract:
A recording medium processing apparatus includes: a pressing unit that presses one surface of a transported recording medium against a to-be-pressed section; and a cutting unit that cuts the recording medium pressed against the to-be-pressed section.
Abstract:
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.
Abstract:
A wrap foil dispenser, comprising a base plate, provided with a channel, through which a blade glides. As part of a cutter assembly which glides along a guide, the blade slides and cuts the foil without touching the plate. The cutter assembly includes an arm which ensures that the blade engages the foil. In case the plate is laterally tilted or the cutter is slid by hand, the cutter assembly moves along a channel to which cutting edges of the blade are placed inside. When the blade is moved, the foil, placed on the upper side of the channel, is cut. The blade's vertical position is uniform as a result of the cutting assembly pressing through the arm's own weight which is limited by a buffer element. The dispenser may include a rotating support, provided with two conical elements that ensure mounting of foil rolls having various dimensions.
Abstract:
A velocity-changing apparatus of the present invention includes: a drum 3 for transporting the continuous web W1 at a transport velocity which is generally equal to a circumferential velocity V(θ) of the drum 3 while changing the circumferential velocity V(θ) periodically at least once per one rotation of the drum 3; a movable member 2 disposed upstream of the drum 3 for feeding the continuous web W1 to the drum 3,; and a cutter 4 for cutting, on the drum 3, the continuous web W1 being transported at the transport velocity which is generally equal to the circumferential velocity V(θ) of the drum 3. The movable member 2 moves according to the change of the circumferential velocity V(θ) of the drum 3 so that a feed velocity at which the continuous web W1 is fed to the drum 3 is generally equal to the transport velocity of the continuous web W1 being transported by the drum 3.
Abstract:
In order to control the cut register (Y18) in multi-web operation in a web-fed press and, independently thereof, to control the web tension in a web section, specific image information or measuring marks from printed webs (BO, BU, BE) and web tensions in different web sections are registered by means of sensors and supplied to a control device—an item of image information or measuring marks from at least one of the printed webs, the said information or marks being suitable for the deviation of the position of the printed image with respect to its intended position, based on the location and time of the cut, that is to say for the cut register error (Y18), is registered before and/or on the common knife cylinder (K8) with the aid of at least one sensor (SE; SO; SU), is evaluated and/or is transformed to form an actual value, which is used for the control of the cut register error of at least one web—and, to correct the cut register error of at least one web, either the speed of at least one clamping point located before the knife cylinder and/or the position of the knife cylinder and, to correct the web tension, the speed of at least one further clamping point is changed, so that the actual value of the part and/or total cut register error of at least one web and, independently thereof, the at least one web tension are corrected to the associated predefined set points. In addition, the invention relates to an apparatus for implementing the method for controlling the web tensions and cut register error.
Abstract:
A recording method comprising the steps in the following order of: correcting a curl of a recording medium by applying heat and pressure to the recording medium; and forming an image on the recording medium by jetting ink onto the recording medium.
Abstract:
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.
Abstract:
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.
Abstract:
A feeding unit for feeding a plastic film in packaging machines for wrapping paper rolls, including: a unit for unwinding the film from a reel; a cutting device adapted to cut the film transversely; a transfer device including, on the right and on the left side of the feeding unit, drive belts configured for engaging the upper and lower faces of the film; and a positioning device including, on the right and on the left side of the unit, a predetermined number of drive belts configured for engaging the upper and lower faces of the film. On each side of the feeding unit, the transfer device comprises two pairs of belts. On each side of the feeding unit, the positioning device comprises a third pair of belts. The three pairs of belts are actuated by independent actuators.
Abstract:
Hybrid printer feeder mechanism, using a commercial printer of any type, such as LED, ink jet, thermal or dot matrix, allowing both single sheet fed input and alternately, continuous and variable width printable medium feedstock, including automated feed and cutting control, with minimal integration of the print engine and feeder.
