Abstract
Devices and methods related to a web stabilizer for stabilizing a moving web with a surface adjacent the moving web and with a supply of moving fluid in a direction parallel to the moving web and a supply of moving fluid in a direction perpendicular to the moving web.
Claims20
A web stabilizer comprising:
- a surface adapted to be adjacent to a moving web of material moving in a web direction,
- wherein the surface includes a first gap adapted to receive and direct a first moving fluid in a first direction parallel with the web direction and a second gap adapted to receive and direct a second moving fluid in a second direction perpendicular to the web direction, such that the first moving fluid provides a stabilizing congruent force to the moving web and the second moving fluid provides a stabilizing transverse force to the moving web.
A method of stabilizing a moving web comprising:
- moving the web adjacent a surface of a web stabilizer in a web direction;
- supplying a first moving fluid through a first gap, such that the first moving fluid travels in a first direction parallel with the web direction, wherein the first moving fluid provides a stabilizing congruent force to the moving web;
- supplying a second moving fluid through a second gap, such that the second moving fluid travels in a second direction perpendicular with the web direction, wherein the second moving fluid provides a stabilizing transverse force to the moving web.
