A cylinder construction in which a flexing force can be exerted on the interior surface of a hollow cylinder intermediate the ends thereof. The hollow cylinder is mounted for rotation about a shaft having an eccentric bearing intermediate the ends thereof. An eccentric bearing at each end of the shaft is adjustable to neutralize the effect of the intermediate bearing or to adjust the flexing force on the cylinder.

A roller adapted to engage and cooperate with a tangential cylinder disposed with its axis substantially parallel with the axis of the roller, the movement of the roller into engagement with the tangential cylinder tending to flex the intermediate portion of the roller away from the tangential cylinder, comprising a continuous hollow cylinder mounted for rotation about the axis thereof and engageable with said tangential cylinder, a control shaft disposed within the hollow cylinder, eccentric means mounted on the control shaft intermediate the ends of the hollow cylinder for exerting a radial force on the hollow cylinder tending to flex the intermediate portion of the hollow cylinder toward the tangential cylinder, thereby improving the uniformity of the engagement between the hollow cylinder and the tangential cylinder, means locking the ends of the control shaft in an adjusted position to orient the eccentric means mounted on the control shaft relative to the axis of the tangential cylinder, an eccentric sleeve mounted for rotation on each end of the control shaft, a bearing mounted on each sleeve for the rotation of the hollow cylinder, each eccentric sleeve being rotatable on the control shaft between two predetermined positions, one position relative to the intermediate eccentric means mounted on the control shaft to render the intermediate eccentric means operative to flex the shaft and another position to release the flexure and neutralize the intermediate eccentric means, and a two-position releasable locking means interconnecting each of the eccentric sleeves and the control shaft for locking the adjustable eccentric sleeves on the control shaft in one of said predetermined positions to render the intermediate eccentric means operative to flex the cylinder, said releasable locking means permitting quick release and adjustment of the eccentric sleeves for rotation on the control shaft from the one predetermined position to the other.
