ABSTRACT:
The present invention provides an improved support blade structure for use on a tension mask frame assembly. The support blade structure is formed of a material having a first coefficient of thermal expansion and includes fastening portions and an insert member connected at a generally central location to the support blade structure. The insert member is formed of a material having a second coefficient of thermal expansion and has a plurality of apertures extending in a row along its length. The aperatures are dimensioned to be larger than the fastening portions passing therethrough to loosely connect the insert member to the support blade structure. This allows the insert member to be connected at the center while it's end are free to slide relative to the support blade structure during thermal cycling.
