(under subclass 168) Apparatus in which the rotary bodies are urged toward one another under limited but continuing force so that the axes of the rolls may spread apart or approach one another as the amount of material between them changes.
(1) Note. Means may be included in the apparatus so that the force urging the rolls together may be adjusted so as to change in amount.

68, Textiles: Fluid Treating Apparatus,
101, for squeezing machines for squeezing a textile while it is subjected to liquid wherein the squeezing action is effected between a roll and a bed made up of rollers and the bed is resiliently mounted, subclass 257, for wringers for removing liquid from textiles having means to release the pressure of one roll on another by bodily shifting one roll away from the other against the action of means constantly tending to press the rolls together and, subclass 259, for wringers for removing the liquid from textiles having means to release the pressure between the rolls effected through abnormal separation of the rolls.
72, Metal Deforming,
240, for means to vary the bite of a roller couple in a rolling mill during operation.
241, Solid Material Comminution and Disintegration,
32, for comminuting apparatus provided with means which rigidly connects two comminutor parts under normal working conditions but which on imposition of an overload, will disconnect the parts to prevent damage to the comminutor.
