Abstract
The invention relates to a flat gasket material and to a process for the production thereof and of a flat gasket therefrom. In the process according to the invention the flat gasket material is preferably constituted by an indeterminate length sheet or web of a carrier material, which is printed on one or two sides with a sealing layer. The finished printed sheet or web of indeterminate length is subsequently punched out to the desired flat gasket shape. The sealing layer is a geometrical structure that is the same on both sides of the sheet and congruent.
Claims13
A process for the production of a flat gasket material comprising the steps of:
- obtaining an indeterminate length sheet or web of a carrier material;
- and
- printing a printing mass onto both sides of the indeterminate length sheet or web of the carrier material to form a continuously applied sealing layer in the form of a geometrical structure, the geometrical structure being the same and congruent on opposite sides of the carrier sheet, and being arranged independent of any gasket configuration of at least one flat gasket to be formed from said indeterminate length sheet or web of a carrier material.
A process for the production of a flat gasket from the flat gasket material comprising the steps of:
- coating a printing mass onto both sides of an indeterminate length sheet or web of a carrier material to form a continuously applied sealing layer of geometrical structure, the geometrical structure being the same and congruent on opposite sides of the carrier sheet, and being arranged independent of any gasket configuration of at least one flat gasket to be formed from said indeterminate length sheet or web of carrier material;
- and
- subsequently, punching out said at least one flat gasket shape from the sheet or web independent of any specific alignment thereof with respect to said geometric structure.
