Abstract
A needle assembly for a stitching machine comprises a stitching jig comprising a needle holder, a needle clamp hoop and a fixing jig. The needle holder has needle sockets to hold a plurality of needles. The needle clamp hoop is connected to the needle holder to retain needles in the sockets. The fixing jig is connected to the needle clamp hoop to couple with a reciprocating bar of the stitching machine. A method for manufacturing an article of footwear upper comprises laying out a first sheet of material; positioning a second sheet of material to overlap with the first sheet of material at an overlap; positioning a felt material adjacent the overlap so that the second sheet of material is between the first sheet of material and the felt material; and felting the felt material to draw fibers of the felt material through the first and second sheets of material.
