Abstract: A sewing machine includes a supporting plate portion and a needle. The supporting plate portion contacts sewing fabric that is moved in a predetermined direction during a sewing operation. The needle is vertically moved between a top dead center above the supporting plate portion and a bottom dead center below the supporting plate portion. The supporting plate portion has a needle hole through which the needle passes. The lower end opening of the needle hole is larger than the upper end opening.
Abstract: A sewing machine has needles reciprocally movable in a first direction through a fabric web and shuttles reciprocally movable in a second direction perpendicular to the first direction. The used shuttles accommodating an empty bobbin is replaced with the new shuttle accommodating a full bobbin. The needles and the shuttles cooperate to form stitch patterns on the fabric web. A device is provided for the automatic replacement of the used shuttle with the new shuttle.
