Hola Eli,

Se trata de planchas o bandejas celulares (es decir, formadas por celdas de aire). No sé si "Brett" es mejor como bandeja, o plancha o panel para tu contexto. A continuación va un texto bilingüe alemán e inglés que habla de Zellenbrett <-> cellular board; más abajo un par de textos de referencia en inglés, y después un texto en castellano. Insisto, no sé cuál acepción se ajusta mejor a tu texto, pero creo que todo esto te puede dar alguna pista.

Suerte!

"Wie ist die Funktionsweise des Handsiegelgeräts?
Fertig gefüllte Becher werden von Hand in das Zellenbrett eingesetzt und mit einer Aluminium-Platine bedeckt. Durch das Verschieben des Brettes kommt der zu siegelnde Becher unter den Siegelkopf. Beim auslösen der Siegelung wird nun die lose Platine auf den Becher heißgesiegelt. In der Zwischenzeit kann der nächste Becher in die andere Zelle gesetzt und mit einer Platine versehen werden."

"The concept of cutting and slotting pasteboard to make small folding cartons was already in use, so they tried similar patterns to make boxes. With the addition of slots to accommodate the thickness, they introduced "cellular board boxes" in 1894. These corrugated fibreboard boxes were much lighter and less expensive than wood boxes, and appeared suitable for the shipment of light products."
