Abstract
A guide member is moved in interlocked relation to a rotary member rotating about the axis of a needle bar, so that a string-shaped material paid out from a bobbin is guided to a needle drop position of a sewing needle. The bobbin having the string-shaped material wound thereon is supported by a support member that is rotatable generally about the axis of the needle bar and disposed over a machine table in such a manner as to not hamper movement of an embroidery frame. The bobbin can be positioned at a distance from a machine head; thus, bobbins of increased sizes can be used. The support member is controlled in orientation, by means of a drive source, in accordance with rotation of the rotary member. The bobbin itself revolves around the machine head, which allows the string-shaped material to be constantly appropriately guided to the needle drop position.
