APPARATUS AND METHOD FOR MANUFACTURING NONAQUEOUS ELECTROLYTE SECONDARY BATTERY

PROBLEM TO BE SOLVED: To provide a manufacturing apparatus and a method that can wind a processed material to be processed by a certain tensional force even if the thin and long material to be processed is processed by repeating acceleration, deceleration and stop.SOLUTION: The manufacturing apparatus includes: a feed-out device 40 that continuously feeds out the long material to be processed with a thickness equivalent to or shorter than 0.2 mm at a constant speed; a processing device 44 that intermittently moves the material to be processed that is fed out by a predetermined distance and applies processing to the material to be processed; a winding device 42 that continuously winds the material to be processed that is fed out of the processing device at the constant speed; a guide 71 that guides the material to be processed so that a portion where the tensional force in a longitudinal direction of the material to be processed is equivalent to or smaller than 10N/m is generated; and a tensional force enhancement device 68 that enhances the tensional force of the material to be processed to a predetermined one. The tensional force enhancement device includes one or more rollers 72 for conveying the material to be processed where a friction coefficient between a surface of the roller and that of the material to be processed is 0.2 or larger, and the roughness of a synthesizing surface is 1.8 μm or larger.
