Abstract

Improvements in devices for feeding pulp in paper-making machines and the like, characterized in that it comprises a closed pulp circuit, adjustable means for introducing a supply of pulp supply into said circuit, discharge means of said flow rate in the machine having a large predetermined width that corresponds to the width of the sheet, and said closed circuit has a first part that extends between the introduction means and the discharge means and where the pulp flow rate it is substantially constant and superior to the greatest possible value of the introduction flow and a second part that extends between the discharge means and the introduction means and that has a drain or weir, and a control that depends in operation on said weir to regulate the introduction means in order to keep the flow rate substantially constant in the first reference ridaparte part of the circuit, this first part of the circuit having a pump, a first conduit attached to said pump and being of a width notably less than the expressed predetermined width of the discharge means a second conduit contiguous to the referred discharge means and having the same width as these discharge means and a distribution or distribution box arranged between these two conduits and having deflection means to laterally deflect the pulp that leaves the first conduit, this distribution box being the same width as the referred means of download.
