Abstract
LA INVENCION TRATA DE UN DISPOSITIVO PARA MEDIR LA POSICION DE OVILLO DE FILAMENTOS, QUE SALE DE FORMA PERPENDICULAR DE LA HILERA, PARA EL SOPLADO EN FRIO, INCLUYENDO SU RETIRADA. PERPENDICULAR AL DISPARADOR (EN DIRECCION A LA HILERA SITIVO DEL DISPARADOR), DELANTE DEL OVILLO DEL FILAMENTO (2) SE ENCUENTRA UN FOCO DE LUZ (1). EL DETECTOR (5) SE ENCUENTRA DETRAS DEL OVILLO DEL FILAMENTO (2). ESTE DETECTOR SE ENCUENTRA EN UN ANGULO "ALFA" CONTRA EL DISPOSITIVO DE ILUMINACION. ESTE ANGULO HA SIDO ELEGIDO TAN GRANDE QUE NO HAY NINGUNA LUZ DEL FOCO DE LUZ (1) QUE INCIDA DIRECTAMENTE SOBRE EL DETECTOR (5). ESTA PREVISTO UN DISPOSITIVO ANALIZADOR PARA CALCULAR LA POSICION DEL OVILLO DEL FILAMENTO (2) QUE PROCEDE DE LA SEÑAL DEL DETECTOR (5).
