A web stabilizer adapted to stabilize a web moving across a span between two components of a web machine or machines, the stabilizer comprising
- a surface facing and adjacent the moving web, and
- at least one transition in the surface of the stabilizer, wherein the transition is a protrusion or recess in the surface between a leading edge of the stabilizer facing a direction of web travel and a trailing edge of the stabilizer and further wherein the transition and the surface in a region adjacent the transition are devoid of air nozzles injecting fluid between the moving web and the surface.
A web stabilizer adapted to stabilize a web moving across a span between two components of a web machine or machines, the stabilizer comprising:
- a stabilizer body having a surface facing, parallel to and adjacent the moving web, wherein the stabilizer body is mounted in the span between the two components of the web machine or machines, and
- at least one transition in the surface of the stabilizer, wherein the transition is a protrusion or recess in the surface between a leading edge of the surface of the stabilizer facing a direction of web travel and a trailing edge of the surface of the stabilizer and further wherein the transition and the surface in a region adjacent the transition are devoid of air nozzles injecting fluid between the moving web and the surface.
