Abstract
Cigarette rods having fragments of metal therein can be efficiently and effectively separated from cigarette rods free of detectable metal particulates. A moving continuous rod exiting a rod-forming unit passes through a ring-like metal sensing device. The continuous rod is subdivided into individual rods of the desired length. A reject valve operates to isolate any rods determined to contain metal fragments. The process is performed to provide high quality control in the manufacture of cigarettes.
