Abstract

Improvements in drums for the wet treatment of the skin, of the type comprising a cylindrical body closed at both ends by flat or pumped bottoms, provided with two horizontal shaft and hollow core plates, for the entry of the liquid inside the drum, characterized essentially by the fact that the outer surface of the drum is provided with one or several channels, in the manner of a ring, which do not cover the entire circular drum, said channels being provided with a uniform or variable section, and the said channels presenting said channels. Different starting and ending points, said points being situated in the same plane perpendicular to the longitudinal axis of the drum or in different planes; because said channels are blind at one end and open at the opposite end, this open end constituting a mouth that is oriented in the direction of rotation of the drum during its work because the said channels are composed of tubular ring elements, coupled to the body of the drum, said channels having lumbreras communicating with the interior thereof, said ports being located between the ends of communication, and output of the channels, preferably in a position closer to the blind end, the referred luminaries being also out of phase between yes, in the same relationship as the outlets; because these channels have as a mission to introduce inside the drum, the corresponding product, whether they are liquids, solids or skins, so that when producing the spin of the drum, the aforementioned products after having traveled a space in a circular direction, are introduced by yes alone inside the drum, through the planned communication zone; because because the communication zones between the channels with the inside of the drum are staggered, the product contained in them, whether skins or liquids, once the drum in working operation, pass arbitrarily from a channel to the drum and from this to the other channel, repeating this operation successively during the treatment; because due to the fact that the section of the channels can be constant or variable, narrowings occur in them in their circular path, which increase the speed of movement of products, liquids, and skins, thus obtaining a greater action of rubbing between the skins, which prepares them optimally to receive the action of the chemical agents, effecting a greater absorption of the same, with which a greater exhaustion of the baths is achieved; because the cylindrical wall of the drum, is provided with doors or peepholes whose function is to allow visual control.
