到与下游横切割机确保在生产夹层元件（25）的无故障运行一个双传送带系统（1）（8）上和清洗装置（19）是在手推车（18），其设置清洁装置（19），滑架（9） 缩回横切割机（8）以接收下一个夹层元件（25）; 被制动那里，然后再加速，在一个生产速度卧速度以上; 到达滑架（9），并且在生产速度和切割到夹层元件的长度后，用同步的速度持续输送滑架（18）之间的所需距离之后（25）重新加速，以便形成为清扫用刷（23）的通道足够宽的间隙。

To ensure trouble-free operation in the production of sandwich panels (25) on a double conveyor belt system (1) with a downstream cross cutter (8) and cleaning device (19) mounted on a trolley (18) arranged cleaning device (19) to the carriage (9) of the cross cutter (8) moved back to receive the next sandwich element (25); is braked there and then re-accelerated, namely to a temperature above the speed of production speed; is further driven with synchronous speed on the production speed and accelerated again after the cutting of the sandwich element (25) to form a sufficiently wide gap for the passage of the cleaning brush (23) after reaching a desired distance between the carriage (9) and transport carriage (18).
