A conveying apparatus for feeding sheets into a processing apparatus is discloses which comprises a plurality of nips within which sheets are gripped and driven along a conveying direction towards the processing apparatus, each nip being defined between a respective drive wheel and an opposing reaction surface. The drive wheels are omni-wheels configured to apply a frictional force to advance the sheets in the conveying direction while permitting free movement of the sheets in a direction transverse to the conveying direction, the reaction surfaces permitting free movement of the sheets in the transverse direction, and an elongate guide is arranged on one side of the conveying apparatus, to extend generally parallel to the conveying direction, the conveying apparatus being configured to urge conveyed sheets in the transverse direction into contact with the guide. A control system is provided to move the guide generally in the transverse direction in dependence upon sensed fiducials on the conveyed sheets, to ensure correct alignment of the sheets in the transverse direction with respect to the processing apparatus.

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.

A feeding roller structure includes a fastening frame, a transmission component, a transmission roller and a floating coupler. The transmission component is assembled in the fastening frame. The transmission component includes a drive shaft mounted on two sides of the fastening frame. The transmission roller is concentrically arranged around the drive shaft. The floating coupler is mounted to the fastening frame. The floating coupler is coupled between the drive shaft and the transmission roller. Two opposite ends of the floating coupler are adjacent to and spaced from the two sides of the fastening frame to form two gaps. Each gap is formed between one end of the floating coupler and one side of the fastening frame. The two gaps limit an angular displacement of the floating coupler.

Provided is a bag making apparatus with a simple configuration that: prevents fluctuations in tension, slippage of seal positions, and meandering or skewing of a web of film; allows the setting of precise initial conditions; reduces or makes unnecessary monitoring, and time and structures for adjustment; allows increased feed rate; and improves production efficiency. The bag making apparatus for packaging containers comprises: a tension control unit for controlling the continuous feed rate according to the values detected by a tension sensor of a tension detection roll; an optical detection unit for simultaneously recognizing multiple marks provided on the surface of the web of film at the respective positions thereof; a skewing correction unit; and a seal position correction unit for adjusting the positions of multiple sealing units in the feed direction.

Device for winding a material web, particularly a metal strip, wherein a coil (1) is supported during the winding process by at least two support rollers (2, 3), wherein the support rollers (2, 3) can be jointly pivoted about a pivot axis (18) between a first, substantially horizontal, position and a second position, which is inclined relative to the horizontal position, by means of a pivoting device (11).

A meandering correction apparatus includes a transport mechanism, an orientation measurement part, a Young's modulus calculation part, a meandering prediction part and a meandering correction part. The transport mechanism transports an elongated strip-shaped base material in a longitudinal direction thereof along a transport path. The orientation measurement part measures fiber orientations of the base material in respective measurement regions on the transport path, the measurement regions being different in widthwise position from each other. The Young's modulus calculation part calculates Young's moduli of the base material for the respective measurement regions, based on the fiber orientations. The meandering prediction part predicts subsequent meandering of the base material, based on the Young's moduli, to output meandering prediction information. The meandering correction part corrects the widthwise position of the base material, based on the meandering prediction information. The meandering correction is made based on the fiber orientations of the base material. Thus, the widthwise position of the base material is corrected without depending on only edge sensors.

An apparatus (20) for steering a web (22), including a web path having at least one steering roller (24) and an exit roller (26), each having a mount; wherein the steering roller(s) (26) each have an axis of rotation and wherein the mounts for the steering roller(s) (26) can pivot those axes with a total of two degrees of freedom. An array (30) comprising a plurality of sensors (30a) for monitoring the position of the web (22) is present connected to a controller so as to determine the position and angular orientation of the web (22). The controller adjusts the pivot(s) of the mount(s) so as to control the angular orientation and the lateral position of the web (22) at a particular point along the web path.

An items processing apparatus for placement and singulation of flat items has a placement device and a feed deck and a separation device. A portion of the placement device is arranged below the placement deck of the apparatus. The feed deck has an opening for an separation roller, and a portion of the separation device arranged above the feed deck. This portion and the separation roller form a gate of the separation device for the singulation of a stack of flat items. A control computer controls the placement device and separation device. The placement device is equipped for edge alignment of a stack of flat items with different formats and has at least two transport elements, which enable an automatic displacement of the stack transverse to the transport direction and placement of the stack at an alignment wall, as well as a transport of the stack in the transport direction toward the feed deck of the separation device, as well as a displacement of the stack counter to the transport direction. A movement assembly is provided to move the portion of the separation device in a direction counter to the transport direction. The control computer controls the alignment state of the transport elements of the placement device of the items processing apparatus, and controls the movement of the portion of the separation device. The aforementioned portion enables a displacement of the stack counter to the transport direction.

A feeding roller structure includes a fastening frame, a transmission component, a transmission roller and a floating coupler. The transmission component is assembled in the fastening frame. The transmission component includes a drive shaft transversely pivoted to two sides of the fastening frame. The transmission roller is concentrically arranged around the drive shaft. The floating coupler is mounted to the fastening frame. The floating coupler is coupled between the drive shaft and the transmission roller. Two opposite ends of the floating coupler are adjacent to and spaced from the two sides of the fastening frame to form two gaps. Each gap is formed between one end of the floating coupler and one side of the fastening frame. The two gaps limit an angular displacement of the floating coupler.
