Abstract:
A device for mounting a first roller relative to a second roller adapted to form a rotatable nip therebetween so as to substantially compensate for changes in engagement between said first roller and said second roller, said mounting device comprising:a bearing assembly for supporting said first roller for rotation; a flexible member associated with said bearing assembly, said flexible member including a parallel spring arrangement, to limit movement of said bearing assembly to movement with a single degree of freedom, said parallel spring arrangement including a part positioned at a fixed spatial location, a first flexure connected between said part and said bearing assembly, and a second flexure connected between said part and said bearing assembly, said second flexure being of substantially equal dimensions to said first flexure and oriented parallel to said first flexure so as to provide movement of said bearing assembly by urging said bearing assembly in a direction to maintain, at least over a limited distance, said first roller in constant force engagement with said second roller so as to substantially prevent any change in the angular speed relationship therebetween; and a stop member to limit movement of said bearing assembly by said parallel spring arrangement.
