English to Italian Tech/Engineering Metallurgy / Casting width cage

Hi, guys,

"***Apron Conveyor*** is a type of conveyor made from individual apron plates that are linked together with hinges on its underside, thus creating a looped carrying surface where materials can be placed. It plays a vital part in several industries by being used to move different materials from one location to another. The apron conveyor is used to deliver a large number of materials across several phases of production and is particularly useful for transport of huge and heavy materials."

The text I have is the following one:

"In Backlight mode, the scanner measures any width that is silhouetted against the backlight. When no material is present, the scanner can easily measure the ***apron plate*** and produce an unwanted measurement. By recording the apron plate width, the scanner will avoid any measurements less than or equal to the ***apron plate*** value.

Would it be just "piastra del trasportatore"?

Grazie...
