Patentansprüche:Patent claims: 1. Geliervorrichtung für dünne thermoplastische Kunststoffschichten auf Bahnen mit einer Hochfrequenzheizung, die aus einem Mikrowellensender und einem mäanderfönnigen Hohlleiter besteht, der sich aus mehreren geraden-, längsgeschlitzten Hohlleiterabschnitten und diese miteinander verbindenden Hohlleiterknien zusammensetzt, wobei die Bahn.durch die Schlitze der Hohlleiterabschnitte geführt und der Hohlleiter mit einer Zusatzheizung versehen ist, die durch Einblasen von Warmluft in den Hohlleiter gebildet ist, die von der Decke der Hohlleiterabschnitte her zuführbar ist, und wobei ferner die Hohlleiterabschnitte, als Doppelkanäle ausgebildet sind, indem oberhalb der Decke der Hohlleiterabschnitte ein Luftzuführkanal vorgesehen ist und in der so gebildeten Zwischendecke Durchtrittsschlitze angeordnet sind, nach Patent 1 218 701,dadurch gekennzeichnet, daß mehrere' Doppelkanäle (10, 16) zu Baugruppen zusammengefaßt sind und daß dabei jede Baugruppe mit mindestens einem für alle Luftzuführ-1. Gelling device for thin thermoplastic plastic layers on webs with high frequency heating, which consists of a microwave transmitter and a meandering waveguide, which is made up of several straight, longitudinally slotted waveguide sections and these together connecting waveguide knees, with the path through the slots the waveguide sections out and the waveguide is provided with an additional heater, the is formed by blowing warm air into the waveguide from the ceiling of the waveguide sections can be fed here, and furthermore the waveguide sections are designed as double channels are by providing an air supply duct above the ceiling of the waveguide sections and passage slots are arranged in the intermediate ceiling thus formed, according to the patent 1 218 701, characterized in that several 'double channels (10, 16) to assemblies are summarized and that each assembly with at least one for all air supply ■ kanäle (16) gemeinsamen Spülluftanschluß (20) ausgerüstet sind.■ channels (16) common purge air connection (20) are equipped. 2. Geliervorrichtung nach Anspruch 1, dadurch gekennzeichnet, daß die Spülluftanschlüsse (20)2. Gelling device according to claim 1, characterized in that the scavenging air connections (20) . im Bereich von die geraden Luftzuführkanäle (16) miteinander verbindenden Leitüngsknien (21) mittig angeordnet sind.. in the area of the straight air supply ducts (16) connecting the ducting knees (21) are arranged in the middle. 3. Geliervorrichtung nach Anspruch 1 oder 2, dadurch gekennzeichnet, daß die Spülluftmenge für jede Baugruppe getrennt einstellbar ist.3. Gelling device according to claim 1 or 2, characterized in that the amount of scavenging air can be set separately for each assembly.
