Abstract
The combination of a bobbin assembly and a support for the bobbin assembly. The bobbin assembly has a core around which a supply of thread can be wrapped. The core has a rotational axis. The bobbin assembly further has a first flange with first and second oppositely facing surfaces. The first surface bounds a storage space for thread wrapped around the core. The first flange has at least one projection from the second surface. The support has a third surface facing the second surface and bearing against the at least one projection for limiting movement of the spool in a direction substantially parallel to the rotational axis with the bobbin assembly operatively connected to the support.
Claims26
In combination:
- a) a bobbin assembly comprising:
- i) a core around which a supply of thread can be wrapped, the core having a rotational axis;
- and
- ii) a first flange having first and second oppositely facing surfaces, the first surface bounding a storage space for thread wrapped around the core,
- the first flange comprising at least one elongate, bendable, fiber-like projection having a length, the length of the elongate projection directed axially relative to the rotational axis from the second surface;
- and
- b) a support for the bobbin assembly, said support comprising:
- i) a third surface facing the second surface and bearing against and bending the at least one projection and limiting movement of the bobbin assembly in a direction substantially parallel to the rotational axis with the bobbin assembly operatively connected to the support,
- the bobbin assembly rotatable relative to the third surface around the rotational axis of the core to allow paying of thread off the core.
A bobbin assembly for a supply of thread, said bobbin assembly comprising:
- a core around which a supply of thread can be wrapped, the core having a rotational axis;
- and
- a first flange having first and second oppositely facing surfaces, the first surface bounding a storage space for thread wrapped around the core,
- the first flange comprising at least one elongate, flexible, fiber-like projection having a length,
- the length of the flexible projection directed axially relative to the rotational axis from the second surface.
