Calender for a sheet of paper

Abstract

A calender for a sheet of paper comprising a metal roll which is rotated by a first driving unit. The calender further comprises a rotatable cylindrical jacket, a pressurizing shoe, and a plurality of support members. The cylindrical jacket is disposed opposite the metal roll to form a calender nip so that the sheet of paper is continuously passed through the calender nip. The pressurizing shoe is provided within the jacket at the position of the calender nip and presses the interior surface of the jacket radially outward to pressurize the calender nip. The support members are disposed inside the jacket so that they are equally balanced in the peripheral direction of the jacket.

1 . A calender for a sheet of paper comprising: 
 a metal roll which is rotated by a first driving unit;    a rotatable cylindrical jacket disposed opposite said metal roll to form a calender nip so that the sheet of paper is continuously passed through said calender nip;    a pressurizing shoe, provided within said jacket at the position of said calender nip, for pressing the interior surface of said jacket radially outward to pressurize said calender nip; and    a plurality of support members disposed inside said jacket so that they are equally balanced in the peripheral direction of said jacket; wherein    each of said support members comprises a shoe; and    at the position opposite to one of said support shoes through said jacket, there is provided a driving roll which is pressed against said jacket to rotate said jacket,    wherein said one support shoe comprises a plurality of divided type shoes divided an axial direction.    
   
   
       2 . The calender as set forth in  claim 1 , wherein a surface of said support shoe is provided with grooves which extend in a direction where said jacket rotates.  
   
   
       3 . The calender as set forth in  claim 1 , wherein a surface of said support shoe is provided with grooves which extend obliquely with respect to a direction where said jacket rotates.
