Abstract
Roll apparatus in which the rotation under the tangential force exerted when the apparatus is in use of the rolling rings relative to the arbor is suppressed by the restoring force of the arbor that is elongated and held in the elongated condition exerting an axial pressure on the rolling ring assembly. The arbor is elongated by expansion of a chamber to which the arbor is connected through a thrust ring which forms a boundary of the chamber. In addition to the thrust ring, the boundaries of the chamber are a flanged ring mounted on the arbor, which is fixed, and the arbor. An adjustable spacing collar is connected to the arbor. After the arbor is elongated, the collar is adjusted to engage the flanged ring, thus locking the arbor against contraction. On removal of the impressed pressure, the adjustable collar in contact with the flanged ring and with the arbor constitute a lock to prevent the reduction of the elongation so that the restoring force of the tensioned mandrel is exerted to prevent rotation of the rolls relative to the mandrel when the apparatus is in use.
