Abstract: The present invention relates to a method for controlling the orientation of fibers within stock (S) flowing through and from a headbox (10) of a papermaking machine. The method includes the steps of generating an excess flow of the stock (12, 13) through edge tubes (14, 16) of a tube bank (18) relative to the flow of stock (S) through the remaining tubes (20, 21) of the tube bank (18). The arrangement is such that excess flow (12, 13) is attained by providing the edge tubes (14, 16) with a cross-machine directional flow area which is greater than the respective cross-machine directional flow area of each of the remainging tubes (20, 21). Stock (22, 24) is bled through the side walls (26, 28) of the headbox (10) adjacent to and downstream relative to the edge tubes (14, 16). The arrangement is such that the bleeding of the stock (22, 24) through the side walls (26, 28) compensates for any tendency for the flow of stock (S) from the respective edge tubes (14, 16) to converge towards each other so that the orientation of the fibers within the stock flowing from the headbox (10) is relatively uniform in a cross-machine direction (CD).

Abstract: In order to produce good quality, large gauge spools with a two-drum winder, the drums (11) and (12) have different diameters and are located at different heights. The main weight of the spool is supported by the drum (11), whereas the drum (12) lies on the spool (13) with the smallest possible nip pressure to transmit the differential torque required to generate the desired winding tension on the spool. The drum (12) may be lowered as the diameter of the spool increases, provided that the winding axis (13A) shifts along a predetermined, preferably straight, vertical or slightly inclined line of displacement (14; 15). An additional central drive which is thus made possible may further improve the quality of the winding. A handling device (50) serves as a multi-functional device for exchanging the rollers, in particular for ejecting the spool, for clamping and positioning the end of the web to be wound, and for separating the finished spool from the web of material (1; 1', 1'', ...).

Abstract: A Pope-type reel (12) for use on a papermaking machine to wind a substantially continuous, traveling paper web (W) into successive wound paper rolls has a primary drive stand (14) which pivots co-axially with the rotational axis (20) of the reel support drum (22). A primary reel spool drive (32) is mounted to the primary drive stand to provide torque to the reel spool (56) from the initial winding of the traveling paper web onto the reel spool while it is supported by a pair of primary arms (13, 13') over the upper periphery of the support drum (22) until the reel spool is rotated downwardly by the primary arms onto a pair of horizontal guide rails (68, 68'). At this time, the reel spool drive is disengaged, and a secondary reel spool drive (58) engages the now partially wound web roll to provide torque continually until the paper web roll is completely wound.

Abstract: The severed end of a continuous, traveling web (11), such as paper, being wound into a wound web roll (12) is attached to the web roll, without requiring human touch, by a pair of adhesive applicators (23, 24) which are mounted on guides (19, 29) to travel longitudinally parallel with the axis of the roll being wound. The applicators may apply either a stripe of glue (21, 22) or an adhesive tape to the circumference of the wound paper roll during the last revolution of the wound web roll, preferably at two locations intermediate the end arm supports (13, 14) of the wound web roll. The applicators are moved radially inwardly to a working position and outwardly to a stand-by position relative to the axis of the rotation of the wound web roll so as to be retracted in the stand-by position when the last wrap of the web on the roll is made to attach the severed end of the web onto the finished wound web roll.

Abstract: A pick-up roll apparatus (10) is disclosed for picking up a tail (T) of a web (W) from a forming wire (12) and for transferring the tail (T) to a press felt (14) wrapping around a portion (16) of the apparatus. The apparatus includes a perforate rotatable shell (18) which is disposed adjacent to the forming wire (12), the shell (18) having a first and a second end (20, 22). A stationary core (24) is disposed within the shell (18), the core (24) defining a tail box (26) which is bounded by the shell (18). The tail box (26) is disposed adjacent to one of the ends (20, 22) of the shell (18) and is selectively connected to a source of partial vacuum (52) such that when the tail (T) of the web (W) is cut on the forming wire (12), the tail (T) is drawn from the forming wire (12) onto the press felt (14) which wraps around the rotatable shell (18). The core (24) also defines a downstream chamber (27) which extends between the first end and the second end (20, 22) of the shell (18). The chamber (27) is bounded by the shell (18) and is connected to the source of vacuum (28) such that during widening of the tail (T) to a full-width sheet (FNS), a flow of air through the press felt (14) and through the perforate shell (18) towards the downstream chamber (27) urges the widened tail (T) towards the press felt (14). The tail box (26) and the downstream chamber (27) are in fluid communication with each other so that any tendency of the tail (T) to detach from the press felt (14) in the vicinity of the tail box (26) during the widening of the tail (T) is inhibited.

Abstract: A method for controlling the parameters of a web winding machine affecting the roll (10) structure which includes a system that utilizes a density analyzer (25), a basis weight measuring device (19, 21), and a caliper measuring device (24) with customized software and a PID control of the equipment controlling the tension, nip pressure and torque transmitted to the web (18) which is being wound and a computer (26). The basis weight and caliper measuring devices (19, 21, 24) are mounted at a location so as to mesure the web properties immediately before it is wound into roll form. The density analyzer (25) is connected to the machine in its usual form. The basis weight and caliper measuring device (19, 21, 24) determines the ''free sheet'' density while the density analyzer (25) determines the ''wound roll density''. The difference between these two values can be used to control the parameters affecting the roll (10) structure.

Abstract: A roll cover apparatus (12) is disclosed for covering a roll (14) of a papermaking machine. The apparatus includes a synthetic cover (16) which is applied to the outer peripheral surface (18) of the roll, which is of an electrically conductive material. A plurality of fibers (20, 21, 22) are randomly dispersed within the synthetic cover such that the plurality of fibers are disposed between the outer peripheral surface of the roll and an outer face (24) of the synthetic cover. An electrically conductive material (26) is applied to the external boundary (28) of at least some of the fibers (20, 22) such that during use of the apparatus, when slippage occurs between a web of paper (W) being treated by the apparatus and the outer face (24) of the cover, an electrostatic charge (30) generated by the slippage is discharged by the conductive material (26) from the outer face of the cover to the electrically conductive roll (14) so that scorching of the web by discharge of the charge (30) through the web is eliminated.
