    摘要: A roll calender, for calendering rubber or synthetic plastics materials and including roll counter bending means and roll oblique positioning means, wherein at least one roll of the calender has journal portions at the ends thereof supported in main support bearings and outer end portions of the journals engaged in spherical bearings, an outer portion of each spherical bearing has each of its two opposite sides rigidly connected to a respective hydraulic cylinder, each hydraulic cylinder has a piston therein with the piston secured to a vertical piston rod, intermediate the ends of the piston rod, such that counter bending of the roll can be effected by pressurisation of the hydraulic cylinders selectively above or below the pistons, and the ends of the piston rod are engaged in respective grooves in respective fixed support members such that said ends are movable horizontally in said grooves in directions substantially perpendicular to the axis of the roll to allow the axis of the roll to be moved into oblique relationship with the axis of a co-operating roll located above or below said roll.

    摘要: A safety device for the roll space within a calender or other roll machine is disclosed. The rolls when rotating, excite oscillations in the beam at the resonant frequency of the beam. This can occur during start-up or during normal operation. The safety device of the present invention comprises a beam and additional mass that is oscillatorily suspended from the beam in order to reduce the amplitude of the beam oscillations at the beam resonant frequency. In addition, a damping element between additional mass and the beam is used to reduce any undesired oscillations due to newly created resonant frequencies introduced into the system.
