Description

Urzadzenia tego rodzaju posiadaja te wade, ze woda wchodzaca w odstepy po¬ miedzy klepkami w czasie czynnosci uci¬ skania, wraca do wnetrza po ustaniu ci¬ snienia i niszczy czesciowo, albo tez nie¬ jednostajnie nasyca wilgocia wycisnieta mase papierowa.Aby niedogodnosc te usunac, usuwa sie wode z przestrzeni miedzy klepkami na krótko przed, wzglednie przy koncu czyn¬ nosci uciskania, przy pomocy tloczonego powietrza lub t. p.Na rysunku przedstawiono jedna z form tego urzadzenia: * Forma zewnetrzna a jest zaopatrzona znanym sposobem we wklad z plaskich klepek b. W czasie czynnosci wyciska¬ nia, woda z warstwy masy papierowej przechodzi w odstepy c miedzy klepkami.''^MmsK^summt^ss^misAs?. ¦ ¦ Ta woda nie odplywa swobodnie, bo w szparach c zatrzymuje sie wsku¬ tek przyczepnosci i wloskowatosci. Ce¬ lem usuniecia tej wody wprowadza sie do szpar c, przez rury d, powietrze sci- snione, albo inny gaz pod cisnieniem, któ¬ ry usuwa wode ze szpar.

PL PLDevices of this type have the disadvantage that the water that enters the gaps between the planks during the compression operation returns to the interior after the pressure is removed and either partially or continuously saturates the squeezed paper mass with moisture. , the water is removed from the space between the planks shortly before or at the end of the compression operation by means of forced air or tp. One form of this device is shown in the figure: * The outer form a is provided with a flat block insert b. During the squeezing operation, the water from the pulp layer turns into spaces between the staves. "" MmsK ^ summt ^ ss ^ misAs. ¦ ¦ This water does not flow freely, because it stops in the gaps due to adhesion and hairiness. In order to remove this water, compressed air or other gas under pressure is introduced into the gaps c, through pipes d, which removes the water from the gaps. The lead should be effective at the end or just before the end of the pressing operation. PL PL
