A bobbin-coil intended to be applied to the matrix or shuttle holder of the sewing and embroidery machines, which is characterized by the fact that it is a simple tubular shaft, whether of paper, cardboard, paste, metal or other material appropriate, on whose axis the thread, silk or cotton in its different classes and colors will be wound, its winding being in a sinuous helical or spiral shape, whose winding, by its consistency, eliminates the containment ailerons of the current coil.
