Automatic underlay system for food products
Efficiently placing paper or film underlays beneath food slices optimizes portion presentation and maintains hygiene, making it an essential component for high-volume food processing lines seeking precision and sustainability.

Places and Aligns Underlays for Food Products
The weUNDERLEAVE series from Weber is designed for precise underlay placement using paper or film for a variety of food products. What sets the weUNDERLEAVE apart is its ability to independently control and position underlays across multiple lanes, making it ideal for high-volume cheese, deli, bacon, and vegetarian food processing lines. With models like the 3000, 3500, 5000, and 5500, it offers flexibility in handling different widths, lengths, and thicknesses of underlay materials. Capable of processing up to four lanes simultaneously, this equipment integrates seamlessly into automated production lines with its fully automatic lane position correction and light barriers for exact portion detection. The open design ensures easy assembly and disassembly without tools for effective cleaning and maintenance, optimizing hygiene standards. Furthermore, the weUNDERLEAVE series supports sustainability initiatives with its efficient material usage, catering to foodservice providers and manufacturers seeking a customized, high-throughput solution.
