RIDER ROLLER ASSEMBLY

摘要

A rider roller assembly includes a beam being translationally moveable substantially vertically relative to a paper web roll being wound. A rider roller in the assembly includes a plurality of rider roll wheels which are mounted to the beam and are individually pivotably so as to engage the wound roll along a nip line. A plurality of supporting arms are articulately linked with the beam for supporting and individually pivoting the rider roll wheels on a swivelling axis in relation to the beam. The individual rider roll wheels are individually loaded against the paper web roll. Double- acting piston/cylinder units are connected to the rider roll wheels for lifting or compensating the rider roll wheels.
