发明名称 Roller press
摘要 Regulating means in a roller press comprising a number of rolls for the adjustment of a press load and a deflection in deflection compensated rolls, especially in a calander stack provided for the glazing of a continuous thin running web like a paper web. The outer-most rolls in said roller press comprise means for the deflection compensation and one or several different press rolls, which are located between these outer-most rolls. Said roller press is provided with a feed-back connection arranged between a control circuit of the press load and a deflection compensation circuit of the deflection compensated rolls, which feed-back maintains a ratio between the press load and the hydraulic pressure in a roll of said compensable rolls. Said feed-back is further arranged in accordance to an alteration of a set point of the press load to control said press load, whereby said feed-back slows down a change speed in the press load so, that said change is carried out in suitable relation to the control speed of the deflection compensated rolls.
