Alignment apparatuses include a frame and contact elements connected to the frame. The contact elements contact items that are to be transported in a processing direction relative to the frame. The contact elements are in permeant fixed positions relative to the frame, and do not move relative to the frame. Adjustable mounts are connected to the frame and move the frame in the processing direction and in a perpendicular cross-processing direction. A controller is electrically connected to the adjustable mounts, and the controller is adapted to control the adjustable mounts to simultaneously move the frame and all the contact elements in the cross-processing direction and the processing direction while rotating the frame. Methods laterally shift imaging on sheets that have had rotational correction performed by such alignment apparatuses.

A correction structure arranged in a feeding path of a document processing device, comprising: a transmitting means consisted of at least a pair of roller set which are arranged symmetrically on the two sides of the feeding path for transmitting the card evenly, a correcting means consisted of a platform movably arranged at the downstream to the roller set, a receptacle formed on the platform, a elastomer arranged in the receptacle for returning the platform to a predefined location, a back wall extended from the platform toward the feeding path, an opening formed on the back wall to let a card go through, and a friction pad arranged at the bottom of the opening to partly jam the opening, wherein the width of the friction pad is less than the width of the feeding path so the friction pad only contacts the center of the card while transmitting the card.

A sheet transporting device includes: a pair of transporting rolls provided to a sheet transport path; a separating component configured to move one of transporting rolls that form the pair of transporting rolls to an open position where the one of the transporting rolls is spaced apart from an other of the transporting rolls; and a switching component having a switching function of switching a position of the pair of transporting rolls between a nipping position and an unnipping position, the switching component being configured to resume the switching function when the pair of transporting rolls once moved to the open position by the separating component is returned to a normal operating position.

The invention relates to a sheet alignment device (5) for a machine for the processing of sheets (B) consisting of a thin, flat material such as paper, cardboard or film, with a feed section, at least one sensor (30, 32) for determining the position and/or alignment of the sheet (B) and also at least two alignment modules (10), each having an alignment roller (12), to which a drive device (14) is assigned in each case, whereby there is assigned to each alignment module (10) a swivel device (16), with which the alignment roller (10) can be swivelled around a swivel axis (A) perpendicular to the feed section. The invention relates also to a machine for the processing of sheets (B) consisting of a thin, flat material such as paper, cardboard or film, whereby a sheet alignment device (5) of the aforementioned type is provided. The invention relates finally to a method for the aligning of a sheet (B) consisting of thin, flat material such as paper, cardboard or film by means of the following steps: the alignment of the sheet (B) is determined, the sheet (B) is speeded up, turned and/or displaced laterally by means of at least two alignment rollers (12), controllable with regard to circumferential speed and alignment, on a feed section.

In a method and a device for correcting meandering of a strip material in an apparatus that performs conveyance of the strip material at a non-contact state by floating a continuously traveling strip material by a floater group, the strip material is tilted by forcibly changing a height position in the widthwise direction of the strip material in at least one of a zone between the most upstream floater in the floater group and a conveyance roll located immediately upstream of such a floater, a zone between two adjacent floaters, and a zone between the most downstream floater in the floater group and a conveyance roll located immediately downstream of such a floater, whereby the height position in the widthwise direction of the strip material above the floater is changed and a static pressure applied to the strip material above the floater is changed to correct meandering thereof.

A rotary frame construction for web transport control devices, includes a carrier frame and a rotary frame in parallel therewith and carrying input and output rollers for a web and pivotably mounted on the carrier frame about a rotation center defined by control surfaces of one frame, the control surfaces scanned by cam followers on the other frame, the frames held in parallel alignment by support rollers on one frame and run surfaces on the other frame, the frames pivotally connected with one another by a drive system, the control surfaces constituted by three control curves formed at outer edges of a cam plate rigidly held on one frame, two of the control curves located on one side of the cam plate and the third on the opposite side of the cam plate, and the other frame has three cam followers respectively associated with one of the control curves.

A correction structure arranged in a feeding path of a document processing device, comprising: a transmitting means consisted of at least a pair of roller sets which are arranged symmetrically on the two sides of the feeding path for transmitting the card evenly, a correcting means consisted of a platform movably arranged at the downstream to the roller set, a receptacle formed on the platform, an elastic object arranged in the receptacle for returning the platform to a predefined location, a back wall extended from the platform toward the feeding path, an opening formed on the back wall to let a card go through, and a friction pad arranged at the bottom of the opening to partly jam the opening, wherein the width of the friction pad is less than the width of the feeding path so the friction pad only contacts the center of the card while transmitting the card.

This disclosure relates to a banknote validator. The banknote validator comprises a banknote path disposed within an interior of the banknote validator, the banknote path including a banknote imaging zone, one or more banknote edge detection surfaces each configured to provide images of edges of a banknote in the banknote path, a banknote imaging sensor configured to provide an image of at least one portion of the banknote imaging zone, and an image sensor configured to capture the images of the edges of the banknote provided by the one or more banknote edge detection surfaces, and capture the image of the at least one portion of the banknote imaging zone provided by the banknote imaging sensor.

A conveyance device includes a tray on an upper surface of the conveyance device and an upper guide below the tray. The tray receives a sheet, and the upper guide defines a conveyance path in which the sheet is conveyed. The upper guide is movable together with the tray to open the conveyance path.
