The patent specification No.96334 that quotes Finland is as prior art, and this piece document discloses a kind of method or a kind of equivalent web material in calender of calendered paper.In the method, the web material of press polish to pass by the top roll of deflection compensation, the lower roll of deflection compensation and a plurality of nips that two or more intermediate calender rolls that is arranged between this top roll and this lower roll forms.These rollers are arranged with vertical basically folded roller.Wherein the roller that equates basically of natural amount of deflection wire shaped of producing of those deadweights is used as intermediate calender rolls.In the method; Basically eliminated the nip load that quality produced fully by a plurality of intermediate calender rolls and the auxiliary equipment relevant with said intermediate calender rolls, and the top roll through this deflection compensation or lower roll and/or calendering nip is applied adjustable load through the external load that puts on this top roll or this lower roll.
General in multi-roller rolling through with the top roll or the lower roll fix in position of a folded roller and should fold roll-in and lean against extruding is provided on the fixed roll, this fixed roll can be top roll, lower roll or intermediate calender rolls/a part of intermediate calender rolls.Alternately, top roll and lower roll press so that neither one intermediate calender rolls locks in place or so that at least one intermediate calender rolls locks in place regularly regularly each other.For example can compensate the amount of deflection of these rollers usually through the deflection compensation equipment that is positioned at top roll and lower roll, thus so that roll nip obtains linear forms.
As known in the art, the axis of felt wrapped roll is parallel in a folded roller of glazing calender.The axis of said felt wrapped roll is positioned at horizontal (CD) that intersects with the paper web traffic direction.Under these circumstances, between adjacent felt wrapped roll, always have the nip of press polish paper web, these rollers form a pair of felt wrapped roll, and the extruding plane of nip is parallel to this axis to the felt wrapped roll in the felt wrapped roll.
The press polish technology of selecting is often more and more to be online press polish, because paper machine needs the increasingly high speed of service.The online press polish in multiple pressure district press polish in the press polish unit is wherein at the pressure roller (like metallic roll) of the smooth surface that inserts (intercalated) with scribble between the roller (like polymer roll) of elastomeric material and form nip.In multiple pressure district calender, because gravity, linear load increases to following nip from last nip, except that using roller safety relief system (roll relief systems).For the linear load of removing downward increase, the amount of deflection line of controlling this roller and in order to open one group of roller fast, using compensation gravity and in the multiple pressure district calender that uses at present through the roller safety relief system (rollrelief) of cylinder with the leverage realization.In the known glazing calender of trade mark OptiLoad that above-mentioned roller safety relief system uses the applicant and TwinLine.
According to the prior art glazing calender is known, and its roller is in groups formed by two groups of rollers, and every group of roller comprises at least two felt wrapped rolls, and for example one group comprises five rollers and another group comprises six rollers.Because the paper machine speed of service and the increase that online calender is needed; Utilize calender to realize that the possibility of various types press polish also needs; This can for example realize through using the nip that lacks than above-mentioned all known nips to move, and wherein paper web passes calender so that at press polish paper web in some possible calender nips only during the press polish.In the process of using the nip operation of lacking than all nips, be known through the bar of hydraulic locking calender for example using the nip run duration that lacks than all nips.With a problem of this structurally associated is can not easily use it effectively producing in the machine, becomes huge basically because in a device like this, point to the power of this calender bearing.
As known according to prior art, for example according to publication FI 96334 and EP 732444, the felt wrapped roll that forms the glazing calender nip is installed through roller bearing, this has caused the problem of some, the solution of these problems needs special device.
In some cases, glazing calender moves with the linear load mode that the roller bearing to felt wrapped roll produces small load even so-called zero load.This is doubt fully in view of roller bearing, because under the situation of zero load, the rolling element of roller bearing can significantly slide rather than roll with respect to bearing bracket stand, and the result forms the rapid wearing and the damage of bearing.Under the situation of roller bearing zero load; Contact point between the rolling surface of the rolling element of roller bearing and bearing bracket stand is unoriented and unsettled unfriendly, because the rolling frame of bearing can not stably in any direction push the rolling element between the said rolling frame with enough power.
In burnishing process, the definition of known calender is so-called press polish operation, and this is meant operation that can be through the calender realization and in calender, confirms through term kN/m * number of nips.Can be known according to the press polish theory, because the increase of linear load, number of nips is not interchangeable fully.Therefore the combination of number of nips and linear load constitutes the standard of calender to concrete paper rank adaptability of estimating.
