Abstract
An improved impeller for a dater, characterized by a single piece of plastic material in which a disk with a fluted edge is distinguished, which extends on one of its sides, forming a drum that fundamentally has a cellular structure with radial partitions, presenting the cylindrical surface of the drum, reliefs according to generatrices formed by the mass of the material of the piece.
