摘要： A printing machine for printing on a web includes a plurality of guide rollers for guiding the web through a simplex and a duplex path in the printing machine. The duplex path is adjacent and laterally shifted with respect to the simplex path. An apparatus for turning or laterally shifting the web and transfer the web from the simplex path to the duplex path includes four rollers. 90° twists are present between rollers 1 and 2 and between rollers 3 and 4. Rollers 1 and 4 are substantially parallel, and rollers 2 and 3 are substantially parallel. Rollers 1 and 4 are substantially at right angles to rollers 2 and 3.

摘要： A method for turning or laterally shifting a web in a printing machine includes guiding the web successively around four rollers. Roller 2 is rotated with respect to roller 1 by about 90°, so that a strand of the web extending between the first and second rollers performs a first twist by about 90°. Rollers 1 and 3 are substantially parallel so that the strand of the web extending between the second and third rollers is straight. Roller 4 is rotated with respect to roller 3 by about 90°, so that a strand of the web extending between rollers 3 and 4 performs a second twist by about 90°.
摘要翻译：用于在打印机中转动或横向移动纸幅的方法包括连续地围绕四个辊引导纸幅。辊2相对于辊1旋转约90°，使得在第一和第二辊之间延伸的幅材的股线执行约90°的第一次扭转。辊1和3基本上平行，使得在第二和第三辊之间延伸的幅材的股线是直的。辊4相对于辊3旋转约90°，使得在辊3和4之间延伸的幅材的股线进行约90°的第二次扭转。

摘要： An automatically-adjusting tensioning mechanism for use in a roll-fed web media transport system, the tensioning mechanism adding tension to the web media, comprising a bracket assembly being adapted to freely pivot around a pivot axis, and first and second tensioning shoe having curved surfaces attached to the bracket assembly. The web media feeds through the tensioning mechanism in an S-shaped media path where the web media is wrapped around the first and second tensioning shoes. The pivot angle of the bracket assembly automatically adjusts in response to differences in a coefficient of friction between the web media and the tensioning shoes such that the tension in the web media has a reduced level of variability relative to configurations where the bracket assembly is held in a fixed position.

摘要： A method for automatically adjusting a level of tension in web media being transported in a roll-fed web media transport system, comprising: receiving web media from a source roller, feeding the web media through an S-shaped media path in an automatically-adjusting tensioning mechanism where the web media is wrapped around curved surfaces on first and second tensioning shoes, and pulling the web media through the automatically-adjusting tensioning mechanism using a feed mechanism. The tensioning mechanism includes: a bracket assembly mounted to a frame which is adapted to freely pivot around a pivot axis. A pivot angle of the bracket assembly automatically adjusts in response to differences in a coefficient of friction between the web media and the tensioning shoes such that the tension in the web media has a reduced level of variability relative to configurations where the bracket assembly is held in a fixed position.

摘要： An apparatus for maintaining uniform tension across a width of a web includes a roller, a first arm and a second arm, a plurality of devices, and a plurality of links. The roller includes a shaft, about which the roller rotates, that defines an axis of rotation. The first arm and the second arm are coupled to opposite sides of the shaft of the roller and to a corresponding one of the plurality of devices such that each device is allowed two degrees of rotational freedom about the arm to which it is coupled. Each of the devices is pivotably coupled to a corresponding one of the plurality of links such that the roller is allowed to pivot about a first axis. Each link is pivotably coupled to a stationary frame such that the roller is allowed to pivot about a second axis.

The roller includes a shaft, about which the roller rotates, that defines an axis of rotation. The first arm and the second arm are coupled to opposite sides of the shaft of the roller. The first arm and the second arm are coupled to a corresponding one of the plurality of devices. The location of the coupling is at the same distance from the axis of rotation of the roller such that each device is allowed two degrees of rotational freedom about the arm to which it is coupled. Each of the devices is pivotably coupled to a corresponding one of the plurality of links. Each link is pivotably coupled to the shaft of the roller through the device to which it is coupled such that the roller is allowed to pivot about a first axis. Each link is pivotably coupled to a stationary frame such that the roller is allowed to pivot about a second axis.
