Verfahren zur Trocknung von Lackleder.

raum entfernt. Es hat sich jedoch gezeigt, dass die Ventilation nur unter bestimmten Bedingungen wirksam ist. Es wurde fostgostellt, dass die schädliche Wirkung des Ozons bedingt wird durch einen erheblichen Feucbtigkaitagehalt der atmosphärischen Luft, mit anderen Worten : Das Belichtungsverfuhren nach Patontschrift Nr. 71472 versgt an feuchten Sommertagen. Das vorliegende Verfahren beseitigt diese Unvollkommenheit dadurch, dass die zur Ventilation benutzte Luft durch geeignete Mittel, z. U. Eismaschinen, möglichst weitgehend von Wasserdampf befreit wird.

Process for drying patent leather.
It is known that patent leather is exposed to sunlight in order to dry it completely. More recently, sun drying has been replaced by irradiation using mercury

space away. However, it has been shown that ventilation is only effective under certain conditions. It was suggested that the harmful effect of ozone is caused by a considerable amount of hot water in the atmospheric air, in other words: the exposure method according to Pat. The present method overcomes this imperfection by removing the air used for ventilation by suitable means, e.g. U. ice machines, is freed as much as possible from water vapor.
The air supplied per unit of time
