Abstract
Two rolls, more particularly embossing rolls are provided which are pressed against each other by pneumatic cylinders for the purpose of fashioning a flat material passing between the rolls. The ends of one of the roll axles are journalled in slides which are actuatable by the cylinders in such a manner as to be deflectable in the pressure direction and in the travelling direction of the material. The elastically suspended roll is thus capable of automatically adjusting itself in such a manner that the axles of the two rolls can adjust to irregularities of the flat material and thus allow a disturbance-free and qualitatively optimal treatment of the material.
Claims9
A device for the treatment of flat materials comprising:
- at least one pair of rolls, each roll having an axle;
- and
- a machine frame for supporting the axle of each of the rolls;
- wherein the flat material is passed in a travelling direction between at least one pair of rolls under pressure;
- and
- wherein at least one of said axles is supported by means of flexible members in such a manner that a mutual flexible adjusting capacity of the axles is provided in both the pressure direction and in the travelling direction.
A device for the treatment of flat materials comprising:
- at least one pair of rolls, each roll having an axle;
- and
- a machine frame for supporting the axle of each of the rolls;
- wherein the flat material is passed in a travelling direction between at least one pair of rolls under pressure;
- wherein at least one of said axles is supported by means of flexible members in such a manner that a mutual flexible adjusting capacity of the axles is provided in both the pressure direction and in the travelling direction;
- and
- wherein stop means are provided to limit the adjusting capacity of the axles in the travelling direction and in the pressure direction to a value between 0 and 2 mm.
A device for the treatment of flat materials comprising:
- at least one pair of rolls, each roll being rotatably journaled on an axle;
- and
- a machine frame for supporting the axle of each of the rolls;
- wherein the flat material is passed in a travelling direction between at least one pair of rolls under pressure;
- and
- wherein at least one of said axles is supported by means of flexible members in such a manner that a mutual flexible adjusting capacity of the axles is provided in both the pressure direction and in the travelling direction.
