Abstract

Improvements in devices for coagulating sheets, from a solution, of the type composed of a conveyor belt with endless drive on whose upper department, above the guide cylinder, on the inlet side, there is a feeding device with slot, characterized in that the upper department of the conveyor belt is provided with lateral limitations and forms a side-sealed trough on which a feeder device for the coagulation liquid has been provided that applies said liquid on the sheet, in a transverse direction to the transport direction, from above in a thin layer since it is equipped with a slot nozzle aligned in a transverse direction to the transport direction, and because a liquid evacuation device is arranged at a distance from the upper department with a slight inclination from the feeding device to the evacuation device tion of the liquid.
