Abstract:
A roll assembly system, comprising:a non-rotating central axle having a first end and a second end; at least two tubular segments, each supported on a rolling bearing and rotatably mounted on the central axle; and a plurality of annular spacers mounted on the axle between the roller bearings to maintain the tubular segments in near proximity; the roll assembly having a stiffness; the first end of the axle having a member mounted thereon for applying pressure against the bearings and the spacers to compress and uncompress the tubular segments along the axle and alter the stiffness of the roll assembly; the roll assembly connected to a member for detecting speed of the roll assembly and sending a signal of the speed to a signal processing device; whereby when the speed of the roll assembly approaches a critical speed, the signal processing device sends a signal to the pressure applying member to vary the pressure against the bearings and spacers to sufficiently stiffen the roll assembly to inhibit harmonic vibration of the roll assembly.
