Abstract
A method of manufacturing a pressure roll including a cylindrical core member having a center shaft, an intermediate layer surrounding the core member and formed from a flexible material, and an outermost layer surrounding the intermediate layer and formed from a high-thermal conductivity material. The method includes forming a plurality of axially extending notches in a cylindrical member to form tongues, radially bending the tongues of the cylindrical member so as to enlarge one end of the cylindrical member, and inserting a core member into the enlarged end of the cylindrical member.
Claims10
A process of manufacturing a pressure roll, the process comprising:
- forming a plurality of axially extending notches in a cylindrical member, wherein said notches extend from one end of said cylindrical member and are spaced about the circumference of said cylindrical member at predetermined intervals to thereby form a plurality of tongues;
- bending the tongues formed by said notches in a radial direction of said cylindrical member so as to enlarge an inner diameter of the one end of said cylindrical member;
- and
- inserting a core member into the enlarged end of said cylindrical member, said core member being surrounded by an intermediate layer formed of a flexible material, wherein said intermediate layer has an outer diameter that is larger than the inner diameter of said cylindrical member.
A process of manufacturing a pressure roll, the process comprising:
- placing a flexible intermediate layer on a core member, wherein a first end of said core member is attached to a first rotary shaft member and a second end of said core member is attached to a second rotary shaft member;
- supporting the first rotary shaft member on a support structure;
- forming a plurality of axially extending notches in a cylindrical member such that said notches extend from one end of said cylindrical member and are spaced about the circumference of said cylindrical member at predetermined intervals to thereby form a plurality of tongues;
- bending the tongues in a radial direction of said cylindrical member so as to enlarge an inner diameter of the one end of said cylindrical member;
- attaching terminal ends of a plurality of the tongues to a plurality of force applying mechanisms, respectively;
- and
- inserting the second rotary shaft member of said core member into the enlarged end of said cylindrical member, wherein said intermediate layer has an outer diameter that is larger than an inner diameter of said cylindrical member.
