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.
Claims27
An air permeable continuous conveyor belt for conveying a tobacco rod in a cigarette rod machine, said belt having two opposed longitudinal edges and comprising:
- first thread means including a plurality of parallel synthetic warp threads;
- and
- second thread means including at least one synthetic weft thread extending from one edge of the belt to the other edge of the belt;
- said first and second thread means being woven together to form a plurality of intersecting points between said first and second thread means, a predetermined number of said plurality of intersecting points comprising bonding points;
- wherein at least one of said first and second thread means includes at least one carrier fiber and at least one hot melt fiber, said first and second thread means are bonded together at said bonding points by temporary melting of said at least one hot melt fiber such that said bonding points are separated from one another by regions of said belt where said thread means are not bonded together, each bonding point having a size and thickness determined by the quantity of hot melt fibers in comparison with the quantity of carrier fibers;
- and
- said bonding points are arranged in a linear fashion with respect to the direction of the at least one hot melt fiber.
