摘要： This invention relates to an oscillating loop taker featuring that a needle thread guiding projection (26) which forms a recess (29) in which the driver member (40) of bobbin case holder (20) is fit together with the wedge (30) is so formed that the inner radius R1 of the leading edge portion (31) of the projection (26) is made shorter than that R2 of the space in which the bobbin case (37) at the base end portion (28) of the projection (26) is housed, the inclination of the needle thread guiding face (31) at the recess side of the projection (26) is set to a desired comparatively large value and further the length in the circumferential direction of the needle thread guiding face (31) is made comparatively long to cause the needle thread (46) to be easily transferred onto the outer circumferential face (47) of the bobbin case (37), thereby causing the bobbin thread (38) to be permitted to pass through between the inner peripheral face in the vicinity of the base end portion and the outer peripheral end portion of the bobbin case (37), causing the bobbin case (37) in the bobbin case holder (20) to be enlarged, causing the diameter of the bobbin, which is accommodated in the bobbin case holder (20), to be enlarged, and causing the winding capacity of the bobbin thread (38), which is wound in a bobbin (39), to be increased.

摘要： The invention relates to an embroidery shuttle (1), comprising a bobbin carrier (20) and a bobbin (10), wherein the bobbin (10) comprises at least two spaced apart running surfaces (12, 14) and a bobbin body (16) extends between the running surfaces (12, 14). A rear thread (30) can be wound onto the bobbin body, wherein the bobbin carrier (20) has bearing surfaces (22, 24) for the running surfaces (12, 14), so that the bobbin (10) is rotatably mounted in the embroidery shuttle (1) about an axis of rotation (d). According to the invention, the bobbin carrier (20) essentially prevents a relative movement of the bobbin (10) along the axis of rotation (d).
