  • Tilted seamless vent and method for making the same
    Patent number: 5080007
    Abstract: A method for making seamless tilted vent comprises the spinning of a mold and a metal sheet to form a tubular member and a flat angular shackle continuously extending from and around the tubular member. The mold is made of a cylindrical member and a flat collar surrounding the cylindrical member at one end. The collar is agularly disposed relative to the cylindrical member and the metal sheet is tightened in abutting relationship against the other end of the cylindrical member. The spinning takes place about an axis corresponding to the longitudinal axis of the cylindrical member. The chasing operation of the metal against the cylindrical member is made until the metal sheet reaches the intersection of the cylindrical member with the collar to form a tubular member. The speed of the mold and of the tubular member is then set between a maximum speed not exceeding 400 RPM and short intervals of speed substantially reduced from said maximum speed.
