Abstract: A printed sheet fiber entanglement apparatus entangles fibers from neighboring printed fibrous layers (e.g., sheets) with one another. As a stack of printed fibrous sheets is built up, periodically a holey plate is loaded against the top sheet of the stack. The guide plate may move the sheet down over the registration pins, and then an array of felting needles are thrust into the stack. An array of needles with upward and/or downward facing barbs is thrust thought holes in the guide plate into the stack through printed sheets closest to the guide plate. As the needles pushed into or are withdrawn from the stack, barbs on the felting needles intertwine fibers from the fibrous sheets through printed marking material and with neighboring sheets. The needle array may translate slightly between multiple thrusts so that a subsequent needling thrust may occur in a slightly new location.

Abstract: An additive manufacturing system for fabricating multi-sided printed composite sheet structures includes a roll fed duplex architecture that prints polymer images on both sides of a substrate sheet to form two-sided 3D composite layers. A substrate web is fed into the machine, and a top side is printed with a wetting agent, powdered, and the excess powder is removed. The image may be pinned to the substrate in a fusing step so that the web can be inverted to print a second image on the other side. The inversion architecture could include inverting rollers, tubes or a Mobius strip that may flip the substrate for backside printing using a single imaging station. The resulting two-side powdered and pinned substrate would then be cut, stacked, heated and compressed to create a 3-D object with more polymer in the stack, resulting in better adhesive binding characteristics at a much higher production speed.

Abstract: Devices include an inkjet printhead having nozzles and a transport item adjacent the nozzles. The transport item includes vacuum openings adapted to maintain print media on the transport item. The transport item moves the print media in a processing direction. The transport item also includes a jetting area lacking the vacuum openings. The jetting area is elongated and is oriented perpendicular to the processing direction. The nozzles are controlled to eject ink to the jetting area when the nozzles are aligned with the jetting area.

Abstract: A cleaning pad can be attached onto an inner surface of a transport belt so the cleaning pad can move with the transport belt along hardware of a marking system, including support rollers and a marking platen to remove ink from the marking platen and support rollers of the rendering device as the transport belt cycles through its typical path within the rendering system.

Abstract: A method operates a three-dimensional object printer for production of cylindrical-shaped objects. The method uses a controller to operate an actuator operatively connected to a cylindrical member to rotate the cylindrical member within at least two supports, operate at least two printheads supplied with different materials to form portions of layers on the rotating cylindrical member with the different materials supplied to the at least two printheads, and operate at least one other actuator operatively connected to the at least two printheads and a curing device to move each of the printheads and the curing device independently of one another in a bidirectional radial direction with reference to a center of the rotating cylindrical member. This operation enables the curing device to be positioned to modify the layers formed on the rotating cylindrical member while the cylindrical member is rotating within the at least two supports.

Abstract: A tandem system of metering and donor rolls is used to apply two different adhesives to a fully adhesive backed multilayer sheet to produce variably distributed adhesives and properties. Each of the two adhesives is unique and is cured differently to create a layer of adhesive that has differing adhesive properties on the sheet. A clear adhesive is applied to a top portion of cards before they are cut from the sheet and has a higher tackiness than the adhesive applied to the rest of the cards on the sheet in order to reduce glue buildup on blades cutting the cards from the sheet.

Abstract: A printer includes a printhead assembly and a dryer. A transport mechanism conveys the printed media in a downstream direction between the printhead assembly and a dryer and between the dryer and an output device. The transport mechanism includes an electric field-generating transport member. The transport member includes a continuous belt supported by rollers. The belt is driven to transport the printed media on an upper surface of the belt. The belt includes an electrically-insulating inner layer and an electrically-insulating outer layer. First and second sets of electrical conductors are positioned intermediate the inner and outer layers. Electrical conductors in the second set are grounded and alternate with electrical conductors in the first set, A charging unit selectively applies a voltage to only a subset of the electrical conductors in the first set at a time, to electrostatically attract the printed media to the upper surface of the belt.

Abstract: A printhead maintenance module is configured as a replaceable unit. The module includes a frame, at least two rollers detachably mounted within the frame, at least two electric motors, a platen, an optical sensor, and a controller. Each electric motor is operatively connected to one of the rollers in a one-to-one correspondence. The controller is configured to operate one of the electric motors to rotate one of the rollers to move media from a position opposite a printhead where a test pattern is printed on the media to a position opposite the optical sensor, receive image data of the printed test pattern generated by the optical sensor, and identify inoperative ejectors with reference to the image data of the test pattern.

Abstract: A method of manufacturing a three-dimensional object facilitates removal of the three-dimensional object from the platen on which the object was formed. The method includes rotating the platen from a horizontally level position to a position at an angle to the level position to enable gravity to urge the three-dimensional object away from the platen and inductively heating the platen to melt support material at the boundary of the object and the platen to release the three-dimensional object from the platen.
