An apparatus (1) for controlling the unwinding of a web (2) wound on a core is disclosed. The apparatus (1) includes a turnbar (10), an actuator (20), a sensor (30), and a controller (70). The turnbar (10) includes a target location to receive the web (2). The actuator (20) is coupled to the turnbar (10) and includes an axis of movement (29). The sensor (30) measures transverse placement of the web (2) relative to the target location and transmits an input signal to the controller (70) when transverse placement of the web (2) differs from the target location. The controller (70) provides an output signal to the actuator (20 to move the turnbar (10) along the axis of movement (29) such that the web (2) maintains substantial alignment with the target location.

A web transport system for transporting a web of media along a web transport path in an in-track direction, including at least one non-contact web guide. The web guide includes a wall having a curved exterior surface, wherein the web of media travels around a bearing portion of the curved exterior surface from a web guide entry position to a web guide exit position, and a hollow interior containing a pressurized liquid. A first row of liquid ejection holes is provided in proximity to the web guide entry position having axes that are inclined toward a downstream direction, and a second row of liquid ejection holes is provided in proximity to the web guide exit position having axes that are inclined toward an upstream direction. The pressurized liquid flows through the liquid ejection holes to force the web of media away from the bearing surface of the web guide.

A total number of liquid ejection holes in the intermediate array is less than a total number of liquid ejection holes in the second row.

A support element for a feed roller for a fibre material, preferably a precursor fibre, to be used in an oxidation or carbonization line for producing carbon fibres, including a base provided with means for attachment to a structure or frame of the oven, a support ring coupled with the base and having at least one passing-through opening for receiving one end of the feed roller, and adjustment means operatively interposed between the base and the ring, and configured to move the position of the ring with respect to the base along at least one adjustment direction, transverse to a central axis of the opening, in order to adjust the position of the ring as a function of the deformations of the roller.

A strip deflection device (1) for deflecting a strip (2), in particular a metal strip, at an angle: at least one deflecting cylinder (3) around which the strip (2) can be deflected by a deflection angle (7) while maintaining strip tension. The angle is defined by the inlet direction (14) and the outlet direction (15) of the strip (2). Rollers (20) on the circumference of the deflection cylinder (3), form bearing faces of equal height for the strip (2) along a wrap around the cylinder. The deflection cylinder (3) can be adjusted between a first (31) and a second operating position (32) preferably perpendicular by an adjusting device (16). Each operating position (31, 32) is associated with a respective arrangement (10, 11) of the rollers (20) and the rollers in that arrangement (10, 11) are oriented in a direction that corresponds to the wrap around the cylinder.
