Abstract
A roller forming device and method for forming a material provided with geometric elements, in particular holes, is disclosed. The device has at least one forming roller and at least one counter roller, wherein a roll gap is configured between the forming roller and the counter roller for carrying through the material. The forming roller has a molding structure on its cylindrical surface, which molds the material when the material runs through the roll gap. The forming roller has carrier elements for an engagement with the geometric elements of the material running through the roll gap.
Claims20
A roller forming device, comprising:
- a forming roller;
- and
- a counter element;
- wherein a roll gap is defined between the forming roller and the counter element;
- wherein the forming roller has a molding structure on a cylindrical surface;
- and wherein the forming roller has a plurality of carrier elements, wherein the carrier elements are engageable with geometric elements of a material running through the roll gap.
A method for forming a material, comprising the steps of:
- running a material through a gap defined between a forming roller and a counter element, wherein the material includes a plurality of formed geometric elements, and wherein the forming roller includes a molding structure and a plurality of carrier elements;
- molding the material by the molding structure of the forming roller when the material is run through the gap between the forming roller and the counter element;
- and
- engaging a first one of the plurality of carrier elements with an edge of the material that defines a first one of the plurality of geometric elements when the forming roller is at a first angular position and when the material is run through the gap between the forming roller and the counter element, wherein the edge is at a trailing end of the first one of the plurality of geometric elements with respect to a direction of movement of the material.
