edge bead

corner bead, angle bead, angle staff, corner guard, corner molding, plaster bead, staff bead

corner bead, 2
1. Any vertical molding, usually a plain, filleted, or quirked bead, used to protect the external angle of two intersecting surfaces.
2. A strip of formed galvanized iron, sometimes combined with a strip of metal lath, placed on corners before plastering to reinforce them.

has developed enhancements to extrusion coating dies and internal deckles that make it possible for converters to reduce edge bead with low-melt-strength polymers while maintaining coat-weight uniformity--two goals that reportedly have often been mutually exclusive with such resins.
The Flex-Master's 65 mm and 75 mm coextrusion station utilizes a feedblock and 1,500 mm die with internal deckles for edge bead savings.
The ACS300 module offers closed cover coating technology and best-in-class edge bead removal precision and therefore enables optimum thick resist processing for 3D integration processes.
Internal deckle parts provide independently adjustable components that seal off portions of the internal flow channel and can be positioned to minimize edge bead.
Dobroth and Erwin [8] focused on the edge bead phenomena and determined that the primary cause of edge beads are edge stress effects, which dominate both surface tension and die swell effects.
Edge-related processes, such as edge bead removal, need to be monitored closely to control performance and defectivity.
One makes the large width adjustment of both internal and external deckles in tandem; a second, smaller motor repositions the internal deckle blade to reduce edge bead.
The dimensionality of the film problem determines, as shown in Table 1, whether two important phenomena can be predicted by a given model: i) neck-in, a downstream reduction in the film's width; and, ii) edge bead, an increase in the thickness of the film at its edges.
Combining best in class coat and develop uniformity with exceptional edge bead performance makes the ACS300 Gen2 the preferred solution for various special spin coating applications such photosensitive polymers like polyimide, PBO or Cyclotene[TM] (BCB).
has five extruders plus a small sixth machine that extrudes edge bead out of trim waste.
