Also disclosed is an electrical coil produced by winding the insulated electrical wire.

Then, the filament bundle is prepared with a preparation fluid and the thread is wound into a coil.

Moreover, the delivery catheter can be twisted in a helical or corkscrew-like manner for traversing certain vasculature, by winding the push/pull wire within the catheter and fixedly attaching it.

Rubber (12A) is wound on before wire winding commences and continues after wire winding stops, so that the assembly exposes no cut wire end.

Each yarn winding mechanism (3) is located against the corresponding spinning assembly and contains a bobbin holder (27) and a yarn layer (28).

Upon fully unwinding the flexible line (26) from the hub (16), the continued rotation of the device (10) causes the flexible line (26) to be rewound upon the hub (16), thus drawing the device back towards the user.

A spindleless spinning machine has a carcass (1) with a rotation drive, spinning assemblies, a yarn removing unit (2) and a yarn winding mechanism (3), all being mounted on the carcass.

The head-to-head abutting together of the two ends of said two spiral wound coiled wire terminations defines a rotational stop of the hinge with the side bar open.
