Abstract
A loop taker comprising a bobbin case holder in which is housed a bobbin whose axis is inclined relative to the rotational axis of a cup-shaped hook body in such a way that the bobbin is kept away from a path of needle movement, and also a sewing machine equipped with the loop taker. Thereby, it is possible to increase the outer diameter of the bobbin or increase the length of the bobbin, and it is possible to increase the quantity of bobbin thread wound on the bobbin.
Claims17
A loop taker comprising a bobbin case holder in which is housed a bobbin whose axis is inclined relative to the rotational axis of a cup-shaped hook body in such a way that the bobbin is kept away from a path of needle movement, the path of needle movement being along a needle axis which intersects a plane containing one axial end of the bobbin, the plane being perpendicular to the axis of the bobbin and the path of needle movement terminating at a point spaced from the axis of the bobbin by a distance less than a distance between the axis of the bobbin and a radially outermost point of the bobbin.
A loop taker as claimed in claim 12, wherein the loop taker is a full rotary loop taker.
A sewing machine comprising a loop taker having a bobbin case holder in which is housed a bobbin whose axis is inclined relative to the rotational axis of a cup-shaped hook body in such a way that the bobbin is kept away from a path needle movement, the path of needle movement being along a needle axis which intersects a plane containing one axial end of the bobbin, the plane being perpendicular to the axis of the bobbin and the path of needle movement terminating at a point spaced from the axis of the bobbin by a distance less than a distance between the axis of the bobbin and a radially outermost point of the bobbin.
