ABSTRACT:
A calender roller apparatus is provided for use with sliver coilers and the like wherein a sliver is passed for delivery between surface engaging coiler rollers rotatably carried on a pair of parallel roller assemblies. One of the roller assemblies is fixed to a base platform and the other roller assembly is pivotably carried by the base platform at a point which is above the center line of the pivoted roller assembly providing a downward biasing force to the pivoted roller against the surface of the fixed roller, so that the sliver will be suitably compressed therebetween eliminating the need for a positive lock-down means which is normally found on pivotable calender rollers.
