A yarn deflection unit for a textile machine, having a housing comprising a curved wall section for forming a radially outer wall section of a curved yarn deflection channel. The solution proposed by the invention is distinguished in that the curved wall section has a yarn guiding groove extending along the curvature for receiving and guiding a yarn.

Techniques are described herein for reducing bowing effects on a substrate while the substrate is being transported, for example in an elevator mechanism, from a first travel path to a second travel path, where the first travel path is offset from the second travel path so that the first travel path is not collinear with the second travel path. The substrate can be any substrate that is bowed and for which one wishes to eliminate or reduce the bow. One specific substrate that can benefit from the techniques described herein are personalized documents such as plastic cards including but not limited to financial (e.g. credit and debit) cards, drivers' licenses, national identification cards, gift cards, loyalty cards, employee badges, and other plastic cards which bear personalized data unique to the card holder and/or which bear other card or document information.

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.

An image reading apparatus includes a document tray, a common transport route, a curved transport route, a linear transport route, a switching device, a document transport device, a first image sensor, a second image sensor, a trailing edge detector, a multi feed detector, a leading edge detector, and a controller. The controller determines a length of the document in the transport direction, on a basis of a time point that the leading edge detector has detected the leading edge of the document, a time point that the trailing edge detector has detected the trailing edge of the document, and a time point that a detection status of the multi feed detector has been switched to a non-detection state, and guides the document to the curved transport route or the linear transport route from the common transport route, according to the length of the document, by controlling the switching device.

A feeder for conveying a workpiece, in particular strip material, in a conveying direction, comprises at least one first pair of side support modules; a base support module arranged between the side support modules; and at least one conveying module; wherein the side support modules are detachably connected to the base support module transversely to the conveying direction to form a U-shaped support structure of the feeder along the conveying direction; wherein the conveying module is arranged on the support structure movably in the conveying direction.

A printing apparatus includes: a first path conveying a printing medium from a manual-feed stacking unit to a printing unit; a second path converging with the first path at a converging section and conveying a printing medium from a cassette; a first roller pair provided downstream the converging section on the first path to nip and convey a printing medium; a first detection unit detecting a printing medium stacked on the manual-feed stacking unit; a second roller pair provided downstream the first roller pair on the first path to nip and convey a printing medium; a second detection unit arranged between the first and second roller pairs to detect a printing medium; and a control unit performing control to start feeding of the printing medium to the printing unit by the first roller pair if the first detection unit detects the printing medium but the second detection unit does not.
