HORIZONTAL SECONDARY STRETCHING APPARATUS AND METHOD FOR ULTRA-THIN FLEXIBLE GLASS

The present invention relates to the technical field of flexible glass manufacturing. Disclosed are a horizontal secondary stretching apparatus and method for ultra-thin flexible glass. The horizontal secondary stretching apparatus for ultra-thin flexible glass comprises air floatation apparatuses, heating units, cooling mechanisms, and a feeding unit, a welding unit, a preheating unit, a transverse stretching extension unit, a longitudinal traction stretching unit, an annealing unit and a winding and wrapping unit which are connected in sequence. The air flotation apparatuses can adjust a pressure difference between the upper and lower sides of a glass plate, thereby solving the problem of downward bending of the glass plate in the transverse conveying process, and ensuring the heating and annealing quality. The welding unit performs butt welding on raw glass sheets in the conveying process to realize continuous feeding. The horizontal secondary stretching apparatus is designed as a multi-layer structure, co
