ABSTRACT:
The pointed tip of a sewing machine needle is immersed in a liquid lubricant as it reaches the lower end of its downward stroke through the material being sewn, so as to coat the tip of the needle with a lubricant and reduce the friction and therefore the heat generated by the friction between the needle and the material being sewn.
