Disclosed is a vehicular engine room manufacturing method wherein the engine room has excellent heat resistance and sound-absorbing characteristics, and scraps generated during the manufacturing process can be recycled. The vehicular engine room manufacturing method comprises the steps of: carding a thermoplastic fiber and a carbon fiber having a length of 10 to 150 mm and needle-punching the same, thereby forming a felt layer; applying heat and pressure to the felt layer, thereby forming a felt board; and applying heat to the felt board and shaping the same is formed in a desired shape.

Felting assembly for a sewing machine. In some embodiments, a felting assembly may include a felting needle clamp including one or more felting needles. The felting assembly may also include a needle plate defining one or more needle openings arranged to allow the one or more felting needles to reciprocate therethrough. The needle plate may be configured to be attached to a sewing machine over a rotary hook of the sewing machine. The felting assembly may also include a connector configured to attach the felting needle clamp to a needle bar of the sewing machine such that the felting needle clamp is offset from the rotary hook of the sewing machine to avoid the one or more felting needles from contacting the rotary hook when the one or more felting needles are reciprocated through the one or more needle openings in the needle plate.

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.

A felting apparatus including a carrier for externally carrying precursor material to rotate with the carrier. A drive is for driving the carrier and the precursor material to rotate. One or more agitators agitate the rotating precursor material. Each agitator is a non-driving agitator.

A felting device includes a rigid body having a bottom surface, an upper surface, and a perimeter surface. The bottom surface includes a plurality of grooves and a plurality of protrusions formed between the plurality of grooves. Each of the plurality of grooves includes a first side and a second side. The first side extends at an acute angle from the second side. The first and second sides define side surfaces of the each of the plurality of protrusions. The upper surface is opposite the bottom surface. The perimeter surface extends between the bottom surface and the upper surface. The perimeter surface defines perimeter sides of a set of protrusions of the plurality of protrusions that abut the perimeter surface.
