Description
Verfahren zur Herstellung von mit faserfreier Cellulosehaut, insbesondere Cellulosehydraten, belegtem Papier, Pappe, Gewebe, Metallfolie, auf Papier kaschierter Metallfolie USW. Bei den mit faserfreier Cellulosehaut, insbesondere aus Cellulosehydraten, belegten Bahnen aus Papier, Pappe, Metallfolien, auf Papier kaschierten Metallfolien, Gewebe u-##@-. hat es sich. gezeigt, daß sich die Bahnen nach kurzer Zeit des Zusammenklebens zusammenrollen. Diese zusammengerollten, mit Cellulosehaut belegten Werkstoffe erschweren äußerst die Weiterverarbeitung, so z. B. in der Kartonagenindustrie, wo die Werkstücke maschinell verarbeitet werden und daher ein Planliegen Bedingung ist. Es wurde vorgeschlagen, die fertiggestellten Bahnen zu strecken, um das Zusammenrollen 'zu vermeiden, doch hat es sich erwiesen, daß diese Maßnahme auch nicht ausreicht.Process for the production of fiber-free cellulose skin, in particular cellulose hydrates, coated paper, cardboard, fabric, metal foil, metal foil etc. laminated on paper. In the case of the webs of paper, cardboard, metal foils, metal foils laminated on paper, fabric u - ## @ -. has it. shown that the webs roll up after a short period of sticking together. These rolled up materials covered with cellulose skin make further processing extremely difficult. B. in the cardboard industry, where the workpieces are processed by machine and therefore lying flat is a requirement. It has been suggested that the finished webs be stretched to avoid curling, but it has been found that this measure is not sufficient either.
Es wurde gefunden, daß der geschilderte Übelstand des Zusammenrollens behoben. mindestens aber verringert wird, wenn vor Zusammenkleben der Cellulosehaut mit der Unterlage die Einführung in die Kaschiervorrichtung derart geschieht, daß die Unterlage mit einer größern Spannung eingeführt wird .als die aufzuklebende Cellulosehaut. Diese Maßnahme ist ganz besonders bei lackierten Cellulosehäuten wichtig, da die Gefahr des Zusammenrollens durch das Lackieren noch erhöht wird, bei Cellulosehy draten jedoch das Lackieren äußerst wichtig erscheint, um durch den Lacküberzug die Cellulosehydrate vor Feuchtigkeit, insbesondere atmosphärischer Feuchtigkeit, zu schützen.It has been found that the described disadvantage of curling up Fixed. but is at least reduced if the cellulose skin is glued together with the pad, the introduction into the laminating device happens in such a way that the substrate is inserted with a greater tension than the one to be glued Cellulose skin. This measure is particularly important in the case of lacquered cellulose skins important, as the risk of curling up is increased by painting, With Cellulosehy draten, however, the painting seems extremely important to get through the lacquer coating the cellulose hydrates from moisture, especially atmospheric Moisture, to protect.
Es ist von ausschlaggebendem Vorteil, wenn die bereits zusammengeklebten Bahnen durch eine Prägevorrichtung geführt werden, deren Prägungen in Strich- oder Punktmanier gehalten sind. Diese Striche unrl Punkte zerstören in Quer- und Längsrichtung die Anziehungskraft der Cellulosehaut.It is of crucial advantage if the already glued together Paths are passed through an embossing device, the embossing in line or Point manner are kept. These lines and dots destroy in the transverse and longitudinal direction the attraction of cellulose skin.
Beim Kaschieren von Pappe mit Papier ist es bekannt, die Kaschierbogen vor dem Zusammenführen mit der Pappe zu dehnen, jeloch geschieht dies nicht zur Verhütung des Einrollens des fertigen Erzeugnisses, sondern zur Vermeidung der Faltenbildung im Kaschierbogen.When laminating cardboard with paper, it is known to use the laminating sheet Before joining with the cardboard to stretch, this does not happen to the yoke Prevention of curling of the finished product, but to avoid wrinkling in the lamination sheet.
