摘要:
A bobbin includes a bobbin main body including flanges at both ends of a bobbin winder spindle for winding the bobbin thread and an outer flange attached to one of the flanges (a second flange) of the bobbin main body. A gap in which a thread end of the bobbin thread is housed is provided between the outer flange and the flange of the bobbin main body.

In order to prevent occurrence of thread breakage and incidental looping, a thread escape recess (18) recessed radially outward relative to an imaginary cylindrical surface inscribed in an inner peripheral portion (17) of an inner shuttle (3) is provided adjacent to a downstream side in a direction of rotation (A) of a needle location hole (11).

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).

In order to prevent occurrence of thread breakage and incident looping, a spring member (50) is provided in an engaging recess of an inner shuttle (3) to resiliently bias an engaging portion (27a) of an engaging strip (27) of a bobbin case (5) on a downstream side of a direction of rotation (A) so as to suppress rattling and vibrations of the bobbin case (5) against the inner shuttle (3).
