Abstract: The invention relates to a method for the ultrasonic welding of a strip consisting of a plastic material for the production of cigarette products, in which method the strip has two free ends which are heated in a connection region by means of ultrasound and joined together to form a closed strip. Ultrasound at a frequency of more than 22 kHz is used.

Abstract: The invention relates to a suction belt for transporting tobacco and/or filter material in the production of cigarettes. The suction belt has a flat belt material that is formed into a ring and has a plurality of openings that are disposed so as to be distributed across the surface of the belt material. The suction belt is characterized in that at least 75% of all openings have an available extent of 0.3 mm or less.

Abstract: A suction belt (1) for transporting tobacco in the manufacture of cigarettes has a fabric (5) comprising warp threads (6) and weft threads (7), the ends (2,3) of which suction belt are connected in a connecting region (4) to form a continuous suction belt (1). The weft threads (7) and/or the warp threads (6), at least in the connecting region (4), have a light-absorbing material (8). The continuous suction belt (1) is laser welded in the connecting region (4).

Abstract: A garniture tape for forming cigarettes and/or filters. The garniture tape having at least one warp thread and having a plurality of weft threads. The at least one warp thread has at least one liquid crystal polymer thread and at least one further thread which has greater roughness than the liquid crystal polymer thread.

Abstract: An endless flat band has a spirally placed, straight pulling element in the form of a thread or a wire extending in the direction of movement. A transverse connection is generated by loops and at least partially by a binding agent, wherein at least one spiral of the pulling element is inserted into a tubular fabric in the knitting machine. Because the spiral is inserted already straightened into a right/right transfer construction between loops or loops and tuck loops, it is achieved that a symmetrical fabric is made which increases the service life of the flat band and improves the useful properties.

Abstract: To permit a woven tape to be used to form cigarettes and filters in cigarette-making machines at least one strand of line fibers and at least one aramid strand, which is made of multifilament aramid fibres, have been twisted together to form a warp thread. This design permits an improvement to tapes for use as a heavy-duty garniture tape, which will meet even very high requirements while for filling the requirements for economical mass production.
