Abstract
The present invention aims to provide a method of producing a high-quality multi-filament spread sheet by spreading the filaments in such a manner that they are orderly disposed in parallel to each other without the quality deterioration and an apparatus used in the same as well as a multi-filament spread sheet produced in the same. The method and apparatus embodied in the present invention are intended to spread the filaments widthwise by subjecting a multi-filament oversupplied by a certain amount under a feeding control mechanism from a yarn supply section to a yarn winding section to air blowing crosswise with the multi-filament so as to transform the filaments into a multi-filament spread sheet. With this method and apparatus, it becomes possible to obtain various types of multi-filament spread sheets.
