Abstract
Un dispositivo de arrastre para carretes de revelado, caracterizado en su esencialidad por disponer, entre los dos primeros filetes en espiral labrados en la cara interna de una de las valonas que constituyen el propio carrete, unos dientes enfrentados y ligeramente inclinados en el sentido del movimiento de la película, que al introducirse en las perforaciones laterales de ésta, facilitan su avance e impiden su retroceso.
