A method and apparatus for applying crosswires to a tension mask. The method includes winding crosswires around various drum assemblies and then using transfer devices to remove sections of crosswires and transfer them to tension mask frame assemblies.

Method and apparatus for applying crosswires to a tension focus mask

The present invention provides an improvement in a color picture tube having a tension mask supported by a support frame mounted within said tube. The mask has a significantly lower coefficient of thermal expansion than the frame. The frame has two substantially parallel cantilevered members, each member has a distal edge to which the tension mask is attached. At least one of the distal edges has two sections separated by a gap therebetween. The two sections include an inner section and an outer section. The mask is glued to the inner section and is welded to the outer section.
