Abstract: A calendar for the production of packing sheets has a heated cylinder of large diameter on which a packing sheet is progressively built-up of layers of rubber-fiber mixture during many revolutions and the cylinder and an unheated counter pressure cylinder of smaller diameter mounted in slidable bearings for rotation and for movement toward and away from the heated cylinder. As the packing sheet is progressively built-up on the heated cylinder, its thickness is continuously measured by feeler rollers pressed lightly against the surface of the packing sheet and associated inductive sensors. In a comparison circuit, the values of thickness-indicating signals received from the sensors are compared with the sum of an initial zero value recorded before rubber-fiber mixture is applied to the circumference of the heated cylinder, and a predetermined desired value. When the value of the thickness indicating signal equals the sum of the zero value and the desired value, the calender is stopped.

Abstract: The apparatus for neutralizing overhanging loads is supported at the roll stand of a calender which opens in downward direction. This apparatus is arranged at both sides of a roll and, during operation, presses from below against the roll suspensions in a predetermined or required position of the roll.

This force is generated or set by movable force transmitters, dimensionally deformable force transmitters or displaceable force transmitters. Upon opening the calender, a force greater than the set force acts upon the load neutralizing apparatus and the force transmitters are moved, dimensionally deformed or displaced, as the case may be, such that a displacement path of the roll into a lower lowered position is provided. The force transmitters for generating the force which compensates for the overhanging loads can be a spring assembly, an air spring or a column or head of liquid supported by a gas cushion.
