Description

technical field [0001] The present invention relates to a sewing machine, and more particularly to a sewing machine equipped with a thread take-up capable of holding the upper thread or the face yarn during the cutting of the face yarn. Background technique [0002] Various types of sewing machines, such as embroidery sewing machines, are usually equipped with a thread take-up device under the needle plate in order to hold the veil or face yarn, so as to prevent the end of the yarn from appearing on the sewing fabric at the beginning of sewing, or to ensure a predetermined amount of yarn or more yarn to avoid finishing. For example, JP-A-60-210290 discloses such a thread take-up. This disclosed thread take-up is at the beginning of sewing or when the yarn is cut, the thread take-up and the shuttle are abutted so as to hold the position of the face yarn and a thread take-up is slightly away from the shuttle during sewing so that the face yarn is released from the holding sta...
