Abstract

Die Erfindung betrifft ein Verfahren zum Kochen von Leimungsmittel im Kreislauf, wobei in dem Verfahren währen des Kochens des Leimungsmittels das Leimungsmittel zu einem Konverter oder einem Suspensionsbehälter (10) geleitet wird, wobei das Leimungsmittel von dem Konverter oder Suspensionsbehälter (10) mittels einer Pumpe (13) zu einer Hauptleitung (11) gepumpt wird, und wobei das Leimungsmittel über die Hauptleitung (11) zu einem Speicherbehälter (15) geleitet wird. In dem Verfahren wird während einer Unterbrechung des Kochens des Leimungsmittels ein Ventil (17) einer Kreislaufleitung (16), die mit dem Speicherbehälter (15) verbunden ist, geöffnet und das Leimungsmittel wird von dem Speicherbehälter zu der Kreislaufleitung (16) und zu der Hauptleitung (11) und zurück zu dem Speicherbehälter (15) geleitet, und das Leimungsmittel wird so lange im Kreislauf geführt, bis die Unterbrechung des Kochens beendet ist. Die Erfindung betrifft auch ein System zum Kochen von Leimungsmittel im Kreislauf, wobei das System einen Konverter oder einen Suspensionsbehälter (10), eine Hauptleitung (11), eine in der Hauptleitung (11) angeordnete Pumpe (13) und einen Speicherbehälter (15) auf- weist. Das System weist eine Kreislaufleitung (16) auf, die den Speicherbehälter (15) mit der Hauptleitung (11) verbindet, um das Leimungsmittel während einer Unterbrechung des Kochens des Leimungsmittels im Kreislauf zu führen.The invention relates to a method for boiling sizing agent in a circuit, in which method during boiling of the sizing agent the sizing agent is fed to a converter or a suspension tank (10), the sizing agent being pumped from the converter or suspension tank (10) by means of a pump ( 13) is pumped to a main line (11), and wherein the sizing agent is conducted via the main line (11) to a storage tank (15). In the method, during an interruption of the boiling of the sizing agent, a valve (17) of a circulation line (16) connected to the storage tank (15) is opened and the sizing agent is supplied from the storage tank to the circulation line (16) and to the main line (11) and back to the storage vessel (15) and the sizing agent is circulated until the cooking pause is completed. The invention also relates to a system for boiling sizing agent in a circuit, the system comprising a converter or a suspension tank (10), a main line (11), a pump (13) arranged in the main line (11) and a storage tank (15). - points. The system comprises a circulating line (16) connecting the storage tank (15) to the main line (11) for circulating the sizing agent during an interruption in the boiling of the sizing agent.
