Paper Feed Roller

      Disclosed is a method of fitting rollers onto a shaft which
feeds papers.

      When fitting a roller made from foaming materials to a shaft,
knurling is made on a part of the shaft to which the roller is to be
fitted.  Then an adhesive is flown into the gap between the shaft and
the roller to increase the power of adhesion (Fig. 1).  The shape of
knurling is Diamond.  Therefore, the adhesive goes all over the
knurling flatly and quickly.

      If high run-out precision and concentricity is needed, a
tight-fitting cylindrical core whose surface has a diamond knurling
can be used.  In addition, this assembly method can achieve higher
productivity than the conventional method.

      Then the sponge roller is fixed to the shaft with an adhesive
through this core (Fig. 2).

      In the above case, the inside of the both faces of the core is
chamfered to increase the power of adhesion between the core and the
shaft (Fig. 3).
