A web splicing system has a cross machine direction vacuum clamp which is brought into engagement with an unwinding web. The web is brought to a stop and vacuum is applied to the clamp holding the paper web against the clamp. A cross machine direction paper cutter such as a water jet is mounted for cross machine direction motion on the clamp. The cutter is operated to sever the web held by the vacuum clamp from the spool or remaining reel. A new reel is prepared by cutting the web in the cross machine direction to form a start or web leading edge which is parallel to the axis of the new reel. Double sided tape is applied parallel to the leading edge and closely spaced therefrom. The vacuum clamp is positionable by conventional means to bring the paper web from the previous reel to overlie the double sided tape. The vacuum box is then brought down into engagement with the new reel and the double sided tape forming a splice. If it is desired to draw paper from the bottom of the reel, the new reel is positioned in the unwinding so paper can be drawn off the bottom of the reel into the rewinder. A flap of paper approximately six to 12 inches wide either on the tail or on the start is used to connect the lower side of the tail to the inside surface of the start.

A method and apparatus for reeling a traveling web, such as the paper web produced on a papermaking machine, comprises the concept of winding the on-coming traveling web onto a reel spool which is horizontally supported rotatively, and which, in a preferred embodiment, moves translationally in a direction from the dry end of the papermaking machine towards the wet end of the papermaking machine as the diameter of the wound web roll increases. The reel spool is supported on a pair of spaced, substantially horizontally disposed rails. The on-coming web is first partially wrapped over a segment of a translationally movable support drum with the upper side of the web facing inwardly toward the surface of the support drum. The support drum is selectively nipped, or not nipped, with the reel spool/web over the web roll as it is commenced to be wound in a winding position, and continues to be wound into a web roll on a reel spool. As the web roll being wound increases in diameter, it is translationally moved upstream while being supported on the substantially horizontally disposed rails, and while torque is maintained on the reel spool.

An extended nip press apparatus is disclosed for removing water from a web. The apparatus includes a rotatable backing roll and an elongate shoe which cooperate with the backing roll for defining therebetween an extended nip for the passage therethrough of the web. The shoe defines a concave surface. A bearing blanket is movably disposed between the backing roll and the concave surface. The arrangement is such that the web is supported by the blanket with the web being disposed between the blanket and the backing roll. A lubricant is supplied between the concave surface and the blanket such that the blanket is slidingly supported by the concave surface during passage of the blanket through the extended nip. The concave surface encompasses a pocket defined by the shoe. The arrangement is such that the pocket is filled with lubricant flowing from the concave surface so that in the event of a wad of the web entering into the extended nip, the wad is yieldingly received within the pocket so that damage to the blanket by the wad is minimized.
