Definitions
- the invention relates to a disk bobbin for receiving a thread package according to the preamble of claim 1 ' .
- the invention is based on the technical problem of simplifying the introduction and fixing of the starting thread in an annular groove of the hub of a lower thread spool.
- the coil is designed in a special way and the annular groove is arranged accordingly, as defined in the following main claim.
- Subclaims relate to advantageous embodiments of the invention.
- the invention solves the technical problem in a particularly advantageous manner. It enables the monofilament yarn threads, which are sewn many times these days, to be fastened to the bobbin safely and quickly.
- This type of yarn is known to have a high elongation of up to 35 percent and one end of the thread tends to suddenly "jump", so that it was previously time-consuming and required practice to securely fix such a thread in an annular groove of the bobbin.
- the accompanying drawing represents the spool according to the invention, which is made of any suitable material, e.g. made of steel, aluminum or plastic, can be produced by conventional manufacturing methods, in a half-sectional view.
- the hub 1 with the bore 2 for receiving the bobbin on the spindle of a known winding device on the sewing machine connects the side windows 3 and 3 ', which the winding space limit laterally outside the hub 1.
- the side window 3 ' has the usual radial locking groove 5, which cooperates in a known manner with a pin on a spindle of a bobbin device, not shown, on the sewing machine for the purpose of latching the bobbin during the winding process.
- the coil of this embodiment is provided with two annular grooves 4 and 4 'arranged in the region of the side disks 3 and 3' and the circumferential surface of the hub 1 is directed obliquely from the center of the hub towards the annular grooves 4 and 4 ', the angle of inclination of both slopes to the horizontal is about 10 degrees.
- the groove width of the ring groove 4 or 4 ' is expediently such that some yarn windings can be wound relatively tightly next to one another, which then cause self-clamping in the groove due to their enlarged cross-section with decreasing tightening, which occurs at the end of the thread with the winding almost empty easily releases again.
- the groove surface can be spherical or have only a bevel over its entire circumference, which leads into a single groove.
- the spool according to the invention contributes to the rationalization of sewing processes.
