Abstract: The invention relates to a device and a method for manipulating a fibrous web (10). The device comprises at least one blower (21A, 21B) provided with a flow-preventing element (24A, 24B) which is arranged to produce at least one blow (26A, 26B) substantially in the direction of the fibrous web (10), and a friction element (28) against which the fibrous web (10) is arranged to be pressed at least partially from the effect of said blow (26A, 26B) and flow-preventing element (24A, 24B) to apply a friction force resisting the motion of the fibrous web (10) to the fibrous web (10). According to the invention, the blow (26A, 26B) is directed substantially away from the friction element (28) and the friction element (28) comprises a surface profile which is arranged such that, from the effect of said at least one blow (26A, 26B), a continuous vacuum is created on the surface of the fibrous web (10) on the side of the friction element (28). Due to its intensified friction effect, the device according to the invention is applicable especially for board and, by means of it, it is possible to form e.g. an air cutting device in the tail-threading section of a board machine.

Abstract: An air stabilization system employing two substantially parallel, codirectional Coanda nozzles, that are positioned adjacent a flexible moving web, with each nozzle exhausting gas at the same downstream machine direction, subjects the moving web to shear forces effective to stabilize the web. Each nozzle includes an elongated slot that is substantially perpendicular to the path of the moving web and a backstep located downstream of the direction of airflow extending from the Coanda slot. The two Coanda nozzles serve as separate points along the machine direction for controlling the height of the moving web. By modulating the velocities or other parameters of gases exiting the Coanda nozzles, the shape of the moving web between the nozzles can be manipulated to present a planar contour for measurements. The air stabilization system can be incorporated into a scanner head to measure the caliper of paper, plastic, and other flexible web products.

Abstract: To accomplish a web transfer, which in reliability is comparable to the one obtained with a closed draw, in any operating environment, but especially where it is desirable to transfer a fast running tissue web (4) from the drying section of a tissue machine, e.g., a Yankee dryer (2), to a reel-up (3), a web support device (10) extends across the width of the web (4) and along a predetermined run of the web support device has a support surface (11) formed by a series of plate member assemblies (23) having means for creating a flow of air in the direction of the web run. Between the web (4) and the support surface (11) the flow of air forms an air layer (15) of reduced static pressure, so as to stabilize the web (4) against flutter. The predetermined run may extend through a calender (7) and past scanner equipment (8). Pneumatic tail threading capabilities may be included.
