摘要： A method of forming a multi-ply web by providing upper and lower outer surface plies of low consistency stock on an intermediate high consistency stock layer joined and delivered from a slice chamber for producing a smooth finished web. A stream of high consistency stock is subjected to highly efficient fiber distributing agitation and stabilization in a tortuous path, and then joins the high consistency stock as an intermediate ply layer between the low consistency stock ply layers. The flow of the intermediate ply layer to juncture with the outer ply layers is modulated and smoothed so that the outer ply layers on the intermediate ply layer will present substantially smooth outer surfaces for the multi-ply paper web.

摘要： At least a substantial proportion of the fibers in papermaking stock are delivered in cross direction orientation to the slice chamber of a headbox and remain in the cross direction orientation for delivery from the slice chamber to a forming surface. The cross direction orientation is effected by a set of partitions defining stock flow passages extending obliquely in the cross direction, receiving the stock flowing in the machine direction and biasing the streams of the stock to flow in generally the cross direction to the downstream ends of the passages from which the streams are diverted in substantially the machine direction towards the slice chamber. The stock with fibers oriented in the cross direction may be supplied to turbulence controlling channels in the slice chamber.

摘要： Apparatus for a paper making machine to form multi-ply web including a headbox having an upper and lower chamber for low consistency fibrous stock to form the outer surface plies of a finished web and an intermediate chamber for receiving a high consistency stock for an intermediate ply with the headbox chambers delivering to portions of a slice chamber, with the outer portions of the slice chamber discharging through a slice opening onto a travelling forming surface and such slice chamber portions having flexible fine scale turbulence trailing elements unsupported at their downstream ends, and the slice chamber having an intermediate passageway receiving stock from the intermediate chamber of the headbox and being defined between solid walls which have inwardly facing surfaces forming a high efficiency tortuous undulating path for the high consistency stock flowing therethrough. In the downstream portion of the passageway the structure is such that the intermediate ply stock is modulated and smoothed so that the outer plies will join the intermediate ply for presenting smooth outer surfaces for the multi-ply paper web.

摘要： By imposing pressure pulses on mobile fibers in suspension in paper making stock slurry in the primary drainage area of the forming zone of a roll former substantially uniform distribution of the fibers is effected in forming of the paper web. A device for effecting the pressure pulses is located adjacent to the primary drainage area and may comprise a pressure pulse producing element of selected shape to control the length of the pressure pulse for the particular character of paper making fiber stock slurry involved in the paper web being formed.

摘要： A press mechanism and method for removing liquid from a traveling fibrous web such as in a paper making machine including first and second elongate extended press nips including an endless looped traveling belt passing over spaced guide rolls with first and second opposed press rolls pressed into the belt to form the extended nips between the press rolls and belt and opposed shoes within the belt pressing outwardly against the press rolls to form the extended nips with the shoes urged against the belt by opposed pistons having a liquid pressure chamber therebetween so that the reaction forces of the fluid on the pistons are cancelled with the web being carried through the nips on felts and following the belt between the nips.
