Abstract
A method of sewing sheet material passing over a throat plate of a sewing machine by providing a nozzle member having a nozzle adjacent a sewing needle at an upstream side thereof with respect to a moving direction of the sheet material and impregnating the sheet with lubricating fluid by supplying the lubricating fluid from the nozzle such that the fluid contacts a surface of the sheet material facing the throat plate. Thereby, component yarns of the sheet are prevented from being severed when the needle pierces through the sheet material such that the severances are minimized.
