Online laser system for cigarette makers
Laser perforation frontend for cigarette machines
The tobacco industry uses MLT laser systems and modules to perforate cigarettes and heat-not-burn (HNB) tobacco products, also called tobacco heating products, THP within the cigarette maker (online).
The laser perforation of the cigarettes or the acetate hollow tube -"stick"- achieves a modified ventilation during the burning phase or during the heating of the tobacco rod. The aim is to precisely control the composition of the tobacco smoke with fresh air or to positively influence the volume flow of the smoke gases. Ultimately, the aim is to achieve a consistently high level of tobacco enjoyment for the consumer, while precisely adhering to legal limits.
MLT has developed various online laser perforation solutions for this process, which are used by many different tobacco producers worldwide. Depending on the cigarette manufacturer and the machine speed, the laser perforation can be easily adapted to the required parameters and performance.
Typically, the MLT laser modules consist of one or two laser sources, each with a front end. Usually 1 or 2 rows are perforated on the cigarette. The number of perforation rows can be switched between 1 or 2 rows. The perforation density is variable and can be adapted to the cigarette circumference. This allows typical ventilation rates of between 6% and 88% to be achieved. By means of our patented polygon technology, circular holes and up to 6 rows per cigarette can be produced in the so-called laser multiplex process.
Especially "tobacco heating products" (HNB, THP, etc.) are very innovative solutions to produce less harmful tobacco products. The laser technology and the products are in constant development.
The main areas of application for the MLVent-inline laser perforation systems are:
