Abstract

1,006,473. Paper making. FARREL CORPORATION. July 17,1963 [Oct. 23, 1962], No. 28304/63. Heading D2A. [Also in Division F2] A crowned calender roller having its profile determined primarily from the general equation for the deflection of a symmetrical beam mounted on two supports, is modified in shape to compensate for changes in the effective crown either when the roller is one of a pair of co-operating rollers on crossed axis or when the roller is, in use, subjected to external bending stresses. As shown in Fig. 6, the surface 31 of a calender roller 29 is of substantially the same profile 30 as that determined from the general equation for the deflection of a symmetrical beam on two supports, but is slightly reduced at both side of the mid-point of the roller. When used as one of a pair of rollers to roll a strip of relatively thin material, e.g. paper, with the rollers on crossed axis as described in Specification 839,611 [Group VIII), the modified crown 31 provides a uniform nip pressure at all points along the lengths of the rollers and produces a rolled sheet of constant thickness across its width. As shown in Fig. 12, a roller 51 has a crowned profile 52 determined from the general equation for the deflection of a symmetrical beam, as before, but is slightly enlarged at 53, 54 on both sides of its mid-point. When in use, the roller 51 is subjected to bending stresses at its two ends. The change in shape occasioned by the bending varies the crown profile, and uniform nip pressure, &c. is provided. Formulae for calculating the modifications to the primary profiles are given, together with tables showing the proportional shapes of the roller crowns.
