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.

Nordson Extrusion Dies Industries, Chippewa Falls, Wis., 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.
* Motorized drives with built-in edge bead control.
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 system is based on a unique platform developed by the company, which detects particles, coat and develop-related defects and EBR (edge bead removal) results with zero-added particles.
Internal deckle parts provide independently adjustable components that seal off portions of the internal flow channel and can be positioned to minimize edge bead. The redesigned EPC die also offers rapid and accurate changes in width; an easily inserted scraper to remove buildup; and fast removal of the deckle system for 'split and cyan.'
[6] employ a two-dimensional isothermal, Newtonian model to compute the neck-in and "edge bead" phenomena.
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. A new spring-loaded device applies pressure to seal the external deckle at the die lip and prevent leakage.
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.
Its first seven-layer line in Lewisburg, Tenn., has five extruders plus a small sixth machine that extrudes edge bead out of trim waste.
Next, viscoelastic effects on neck-in and edge bead phenomena were investigated.
