A method for forming paper straps is provided. The method may include providing a paper strip from a base sheet and directing the paper strip through a first die to form an intermediate string. The method may further include directing the intermediate string from the first die through a second die, the intermediate string exiting the second die in a substantially non-twisted state. Related apparatuses and devices to form paper straps are also provided.

An on-line automated analyzer of macrocontaminants is described. The analyzer is for a pulp and/or a white water stream, the analyzer comprises: a pulp classifier separating a sample from the stream into a fraction of macrocontaminants; a contaminant chamber enclosing a contaminant cell receiving the fraction; an optical chamber comprising an optical detector connected to the cell capturing at least one detected image; and a control chamber taking the at least one detected image and conducting an image analysis to determine type and quantity of at least one macrocontaminant in the fraction. The method of analysis of macrocontaminants is also described herein, the method comprises: separating a sample from the stream into a fraction of macrocontaminants; producing at least one detected image by optical measurement of the fraction; and analyzing the at least one detected image and determining the quantity and type of at least one macrocontaminant in the fraction.

Oxidized white liquor is heat treated to increase the concentration of polysulphide measured at 285 or 286 nm (PS) or measured at 416 nm (PS) and the PS/PSor PS/PSratio, whereby the content of active polysulphide in the total polysulphide is increased which active polysulphide can be exploited to increase pulp yield in Kraft pulping.
