A wrinkle-reduction system includes two media guiding rollers located in proximity to first and second edges of a media, each media guiding roller having a corresponding roller axis and having one or more grooves formed around its exterior surface. The media travels along a transport path past the media-guiding rollers with a first side of the media facing the exterior surface of the web-guiding rollers. Air sources provide an air flow into the grooves in the media-guiding rollers, the air flow being directed between the first side of the media and the exterior surface of the media-guiding rollers thereby producing a Bernoulli force to draw the media toward the media-guiding rollers. The first roller axis is not parallel to the second roller axis such that when the air sources are activated the media guiding rollers impart a lateral stretching force to the media in the cross-track direction.

A flexible and continuous substrates-conveying sheet has a plurality of to be processed substrates disposed on or in it. A nondestructive transferring unit includes a plurality of first transferring rolls and a plurality of second transferring rolls. The first transferring rolls make contact with a first surface of the substrates-conveying sheet where that surface can have electrostatically-induced charge formed thereon. Each of the first transferring rolls includes a first central portion charged with a positive electric charge and a first outer portion surrounding the first central portion. The second transferring rolls make contact with the first surface of the substrates-conveying sheet. The second transferring rolls are disposed alternately with the first transferring rolls. Each of the second transferring rolls includes a second central portion charged with a negative electric charge and a second outer portion surrounding the second central portion.

The device (100) is destined to receive flanked continuous strips (1, 2) from an arrival line (L), and feed them towards a transversal cutting station (SR). The device (100) comprises: a basin (3), associated to a terminal part of the arrival line (L), destined to enable formation, in each of the strips (1, 2) of a free loop (A1, A2) in a downwards direction; deviator organs (4), at a 45° angle, provided downstream of the basin (3), destined to guide the strips (1, 2) such as to orientate them perpendicularly to the arrival direction, horizontally centered and correctly staggered in height such as to enter the transversal cutting station (SR).

A magnetically enhanced roller for handling of magnetically attractable substrates comprises a rotatably fixed shaft and a sleeve circumscribing the rotatably fixed shaft. The sleeve configured to rotate around the shaft. The roller further includes an array of magnets adjacent to the shaft. Individual magnets of the array of magnets are oriented to provide magnetic field lines along a direction orthogonal to the rotatably fixed bearing shaft.
摘要:
A method for operating a processing machine, in which a first web section of a product web is delimited by closing a first clamping point and a second clamping point, such that a first web tensile force prevails in the web section. A third clamping point within the first web section is closed, so that a second web section is formed between the first clamping point and the third clamping point. At least one of the closed third clamping point and the closed first clamping point are adjusted by an angle, so that a second web tensile force in the second web section is changed, preferably increased.
摘要:
An apparatus for manufacturing a thin-film laminate prevents loosening of a strip-shaped flexible substrate at the time of conveying or misalignment of the strip-shaped flexible substrate with respect to a winding roller at the time of winding. In the apparatus, a strip-shaped flexible substrate in a lateral direction is conveyed by positioning longitudinally the width direction of the strip-shaped flexible substrate wound in a roll shape. The apparatus includes a deposition device having a deposition chamber for forming a thin film on the strip-shaped flexible substrate, a winding roll for winding a thin-film laminate, and an adjustment roller to prevent a loosening or misalignment of the strip-shaped flexible substrate between a pair of grip rollers and the winding roll, and the pair of grip rollers arranged in front of the adjustment roller to convey the thin-film laminate while maintaining a given height.

A modular roll bar assembly for use in a continuous web imaging device includes a plurality of roll bars and a support frame configured to operably support the plurality of roll bars such that the plurality of roll bars define a web path having a non-linear shape with an entrance end and an exit end. The entrance end is configured to receive a substantially continuous web of substrate material, and the plurality of roll bars is configured to guide the continuous web past the exit end. A load cell is operably coupled to the support frame and configured to generate a signal indicative of a down force applied to the support frame. A controller is operably coupled to the load cell to receive the signal and to correlate the down force applied to the support frame indicated by the signal to a tension measurement value for the continuous web.
摘要:
The invention comprises separating the strippings of a strip of paper and of a precut prepreg into strippings to be discarded and blanks to be kept using a suction roller that is tangent to the strip along an action line. In a downstream position, a device collects the blanks on said rectilinear path, and a device closer to the roller discharges the strippings. The paper runs through the device along said rectilinear path while maintaining the blanks thereon, and a strip temporary diversion device, capable of orthogonal movement relative to the strip, temporarily diverts the strip and brings it closer to the roller in order to facilitate the initial peeling of the strippings.
摘要:
A processing portion (3) is arranged in a position above and on a lateral side (right side in the drawing) of a roll body accommodating portion (2), and an engagement portion (11a) of a guide plate (11), which is positioned between the roll body accommodating portion (2) and the processing portion (3), engaging with a continuous sheet (1) is positioned while being biased to an opposite side (left side in the drawing) of the processing portion (3) with respect to a position directly above a central axis of a roll body (1a), or preferably to an opposite side (left side in the drawing) of the processing portion (3) with respect to an outermost end of the roll body (1a). The engagement portion (11a) of the guide plate (11) engages with the continuous sheet (1), thereby allowing the continuous sheet (1) to be once guided to the opposite side (left side in the drawing) of the processing portion (3) with respect to straight lines (L1) and (L2) each connecting a drawing out portion of the roll body (1a) and the processing portion (3) to then be guided to the processing portion (3).
