| 摘要 |
The present invention relates in a general way to a device which includes: - a support (made of wood, aluminium, plastic or derivatives), having a 9 DEG slope, pierced along its axis by a 10 mm-diameter hole serving to receive the spindle of the plate, and a screw 4 perpendicular to its axial hole and "perceiving" it; - a spring 2 fixed by means of two screws 3, which is special because of its shape and arrangement, and which is housed in the support 1 and serving to hold the cone of the cardboard 6. This device allows the integral coupling of the assembly comprising the plate, spindle and bobbin of thread and thus defines an optimum path for the thread as it is unwound. <IMAGE>
