Center registration system

A registration system includes nip rollers for conveying a sheet in a process direction when the nip rollers are in an engaged position, and first and second sets of omnidirectional rollers arranged perpendicularly to each other, for conveying the sheet in the process and cross-process directions, respectively. The omnidirectional rollers each allow the sheet to slide, relative to the omnidirectional roller, in a direction parallel to an axis of rotation of the omnidirectional roller. The nip-rollers are movable from the engaged position to a disengaged position, in which the first pair of omnidirectional rollers convey the sheet in the process direction. A feedback system includes sensors for determining registration errors of the sheet and a control system controls the omnidirectional rollers to reduce the registration errors in the sheet while the nip-rollers are in the disengaged position.

Sheet Conveying Apparatus

A sheet conveying apparatus includes: a conveying roller configured to convey a sheet in a conveying direction; driven rollers arranged with intervals in a width direction intersecting with the conveying direction, the driven rollers being opposed to the conveying roller in a direction perpendicular to the conveying direction and the width direction; and coil springs provided corresponding to the driven rollers respectively and serving as rotating shafts for rotatably supporting the driven rollers, wherein the coil springs include a right-handed twining coil spring and a left-handed twining coil spring.

Elastic non-woven lamination method and apparatus
10350870 · 2019-07-16 · ·

A lamination system includes a film supply, a non-woven material supply, and a laminator. The laminator causes a film from the film supply to be laminated to a sheet from the non-woven material supply to establish a laminated sheet.

Feed apparatus and image recording apparatus

There is provided a feed apparatus including a support unit, a feed roller, a swingable arm to support the feed roller, a guide unit, a movable member movable to a retracted position and a protruding position at which the movable member can abut against the sheet supported by the support unit, a driving source, driving transmission units; and a contact-separating mechanism to move the feed roller to a separated position and an abutment position at which the feed roller abuts against the sheet supported by the support unit. In a state in which the movable member is the protruding position and the feed roller is the separated position, a time required to start feeding of the sheet by the feed roller moved from the separated position to the abutment position is longer than a time required to shift the movable member from the protruding position to the retracted position.

OPERATING UNIT FOR INTERLEAVING MACHINES

An interleaving unit, comprising a pair of rolls (1, 2) set alongside one another and counter-rotating and provided with respective first and second folding tools (3, 4; 5, 6) set at a distance from one another along the circumferential development of the respective peripheral surfaces so as to operate in a common point of tangency (Z) on a succession of sheets (7a, 7b) fed between the two rolls, said tools (3, 4; 5, 6) being set on respective mobile cylinder sectors (8, 9, 10, 11) to enable positioning thereof at an adjustable distance apart along the circumferential development of a corresponding roll (1, 2), said interleaving unit comprising means (M1, M2, U) for independently adjusting the speed of rotation of one or more of said sectors according to their angular position in order to reduce or increase the peripheral speed of said sectors with respect to a speed of feed (Vm) of said sheets.

ELASTIC NON-WOVEN LAMINATION METHOD AND APPARATUS
20180333943 · 2018-11-22 ·

A lamination system includes a film supply, a non-woven material supply, and a laminator. The laminator causes a film from the film supply to be laminated to a sheet from the non-woven material supply to establish a laminated sheet.

ANTI-SKEW STRAIGHTENING MECHANISM
20180327206 · 2018-11-15 ·

One example embodiment in this disclosure provides an apparatus comprising an opening configured to receive a banknote into a banknote path. The apparatus also includes a plurality of inboard transport wheels positioned in the banknote path and configured to transport the banknote in a direction longitudinal to the banknote path. The apparatus also includes at least one initial transport wheel positioned in the banknote path and nearer to the opening than the plurality of inboard transport wheels, the at least one initial transport wheel configured to transport the banknote from the opening to a first of the plurality of inboard transport wheels. The at least one initial transport wheel causes the banknote to pivot around the first inboard transport wheel when a leading edge of the banknote contacts the first inboard transport wheel. Pivoting causes banknote to contact a second of the plurality of inboard transport wheels.

UNDERLAPPING SHEET FEEDERS
20180312355 · 2018-11-01 ·

A sheet feeder comprises a roller configured to rotate about an axis and an input drive configured to deliver single sheets to the roller such that a leading edge of each sheet is substantially parallel to the axis. The roller comprises a plurality of flexible fins extending along the axis. As the roller rotates, one of the sheets can be lifted by the rotating fins to pass over the roller, while the leading edge of a following sheet is delivered to the roller in an underlapping relationship with the first sheet.

PICKUP ROLLER HAVING FRONT END ALIGNMENT MEMBER AND MEDIUM SEPARATING DEVICE USING SAME
20180229952 · 2018-08-16 ·

Provided herein may be a pick-up roller with a front-edge alignment element and a media separation apparatus using the pick-up roller. The pick-up roller may include a pick-up element configured to pick up and transfer a media sheet, and the front-edge alignment element provided at a position opposite to the pick-up element. During a process of picking up a stacked media sheet and transferring it into a space between a feed roller and a separation roller unit, the front-edge alignment element may align in advance a front edge of a media sheet disposed subsequent to the medial sheet that is being transferred, to a position of the entrance between the feed roller and the separation roller unit, and thereafter, the pick-up element may pick up the media sheet aligned by the front-edge alignment element and transfer it into the space between the feed roller and the separation roller unit.

Cutting plotter
10011034 · 2018-07-03 · ·

A cutting plotter includes a driving roller, a rotating shaft, pinch rollers, a cutter, and a press roller. The driving roller extends in a direction of a first axis and rotates around the first axis. The rotating shaft extends in a direction of a second axis parallel to the first axis, and is configured to be rotatable around the second axis. A passage through which a cutting target passes is formed between the driving roller and the rotating shaft. The pinch rollers are provided on the rotating shaft. The cutter is selectively pressed to the cutting target. The press roller is provided on the rotating shaft between the pinch rollers, and presses the cutting target against the driving roller. The press roller is formed by a coil spring into which the rotating shaft is inserted.
