Abstract: A method and apparatus for reeling a traveling web, such as paper produced on a papermaking machine, includes a pair of spaced, horizontally disposed rails (12, 12') for supporting one or more reel spools (18). One of the reel spools (18a) is moved into an initial position (33) and rotated to bring it up to machine speed. A support drum (48) is moved translationally substantially vertically (52, 54, 56) from beneath the rotating reel spool to engage it along a nip line of contact (N1). The on-coming web (W) is directed into the nip of the rotatably driven reel spool to begin the web reeling process to build a wound web roll (8). After having reached a certain diameter the web roll (8) is moved horizontally from the initial position (33) to a winding position (41) while maintaining it rotatively supported on the rails (12, 12'). In the winding position (41) the support drum (48) engages the web roll (8) along a nip line of contact (N2). The support drum (48) remains in contact with the wound web roll building upon the reel spool (18) continuously throughout the whole winding procedure until the desired wound web roll diameter is attained. The reel spool/wound web roll is maintained under the control, or influence, of three forces at all times during the formation of the wound web roll: 1) torque from a drive means attached to the reel spool, 2) nip pressure from the support drum, 3) web tension of the web coming onto the driven reel spool. The support drum preferably partially supports the wound web roll at all times during the reeling process, and the wound web roll remains horizontal on the support rails (12, 12') at all times as the wound web roll is formed.

Abstract: A drying apparatus (10c) is disclosed for drying a web (WC) of paper. The apparatus includes a plurality of top felted drying sections (60c, 62c, 64c, 78-80) for drying the web. Each of the drying sections is arranged in succession such that the web is restrained against cross-machine and machine directional shrinkage during passage of the web through the plurality of drying sections. A further single drying section (96) only is disposed downstream relative to the plurality of drying sections such that the web extends between the plurality of drying sections and the further drying section. The further drying section (96) includes an upper tier (98) of dryers and an upper plurality of rolls (100-102) which are disposed between adjacent dryers (103-105) of the upper tier (98). An upper felt (106) extends alternately around each dryer (103-105) of the upper tier (98) and each roll (100-102) of the upper plurality of rolls. The further drying section also includes a lower tier (107) of dryers (108-110) and a lower plurality of rolls (111-112) disposed between adjacent dryers of the lower tier (107). A lower felt (114) extends alternately around each dryer (108-110) of the lower tier (107) and each roll of the lower rolls. The arrangement is such that the web extends in open draw (40c, 42c, 44c, 46c) between each dryer of the upper (98) and lower tiers (107) so that any tendency of the web to curl is controlled during movement of the web through the further drying section (96).

Abstract: A short dwell coater apparatus (10) is disclosed for applying coating material (12) onto a web (W) guided by a backing roll (14). The apparatus (10) includes a coater housing (16) which is disposed in close proximity to the backing roll (14). The arrangement is such that the web (W) guided by the backing roll (14) moves between the backing roll (14) and the housing (16). The housing (16) defines an application chamber (18) which is open towards the web (W) and which extends along the web (W) in a cross-machine direction. The application chamber (18) is connected to a source (20) of coating material (12) such that the coating material (12) is applied to the web (W) during movement of the web (W) past the chamber (18). The coater housing (16) has an upstream lip (22) which is disposed upstream relative to the chamber (18) and adjacent to the web (W). The lip (22) defines an upstream coating overflow (24) for permitting excess coating material (26) to flow therethrough. A flexible coater metering blade (28) is disposed downstream relative to the chamber (18). The blade (28) extends from the housing (16) towards the web (W) for metering the coating material (12) applied to the web (W). A perforate conduit (30) is disposed within the chamber (18) and extends in a cross-machine direction. The conduit (30) permits the flow (32) therethrough of a vortex (34) of entrained air generated within the chamber (18) such that in use of the apparatus (10), when the vortex (34) of entrained air is generated within the chamber (18), the air (34) flows through the perforate conduit (30) away from the chamber (18) so that streaking of the coating material (12) due to the intermittent escape of the entrained air (34) past the metering blade (28) is inhibited.
