CYCLOPROPANE RING-CONTAINING TERTIARY AMINE COMPOUND, MANUFACTURE AND FUNGICIDAL COMPOSITION

摘要

PURPOSE:To eliminate the adverse influence of thrust forces in a screw-down direction and to support thrust forces uniformly by providing wheels at the front and rear in the rolling direction of roll chocks to both end parts of supporting arms which are mounted freely horizontally turnably in central parts. CONSTITUTION:A crossing angle theta is given to work rolls 1 via roll chocks 2 abutting to pusher bars 6 guided by the guides 5 of housing 4 by the forward and backward movements of said bars. Then the thrust force T generated in the rolls 1 is transmitted from the supporting parts 2a, 2b of the chocks 2 to supporting arms 8 via pin joins 11 in the central part. Further said force is supported by the clamping plates 13 forming guiding grooves 15 mounted to the housing 4 from wheels 10 via automatic self-aligning roller bearings 9 in both end parts of the arms 8. Then the chocks 2 are supported by the wheels 10 and the friction state thereof is made into rolling friction, whereby the influence that the frictional force generated by the force T gives upon screw-down forces is decreased. Since both wheels 10 are maintained parallel by the arms 8 and the bearings 9 with respect to the plates 13, the force T at both wheels is made uniform.
