Abstract

An air permeable, continuous conveyor belt for conveying a tobacco rod in a cigarette rod machine including parallel warp threads (31) and parallel sections (30a) of weft threads (30), the intersection points of which are in a regular grid. At least one warp thread (31) and/or at least one weft thread (30) includes at least one carrier fiber and at least one melt fiber. The bonding points (32) achieved by melting of the intersection points are arranged in linear fashion. As a result, selective adhesion of the weft threads to the warp threads can prevent the separation of individual fiber particles without reducing the air permeability of the belt.
