Abstract
The present invention relates to a method for portion-packing of an oral pouched snuff product (1′, 1″). The method comprises a) supplying and advancing a tubular web (19, 19′, 19″) of packaging material enveloping a continuous feed (23, 23′, 23a″, 23b″) of filling material in a direction of travel (L), b) forming transverse seals (39) in the tubular web across the continuous feed of filling material by means of ultrasonic welding, the transverse seals extending in a transverse direction (T) being perpendicular to the direction of travel. The present invention further relates to an arrangement (17, 17′, 17″) for portion-packing of an oral pouched snuff product.
Claims21
A method for portion-packing of an oral pouched snuff product, said method comprises:
- a) supplying and advancing a tubular web of packaging material enveloping a continuous feed of filling material in a direction of travel,
- b) forming transverse seals in said tubular web across said continuous feed of filling material by ultrasonic welding with an ultrasonic welding unit configured to perform simultaneous transverse welding and cutting of said tubular web, said transverse seals extending in a transverse direction perpendicular to said direction of travel,
- c) cutting said tubular web with a cutting edge comprised in said ultrasonic welding unit, wherein:
- said cutting in step c) is performed in a welded area of said transverse seal, while performing step b), and
- said ultrasonic welding unit comprises a single operation surface performing said transverse welding and cutting.
An arrangement for portion-packing of an oral pouched snuff product, said arrangement comprising:
- one or more supply units for supplying and advancing a tubular web of packaging material enveloping a continuous feed of filling material in a direction of travel,
- an ultrasonic welding unit for forming transverse seals in said tubular web across said continuous feed of filling material, wherein said welding unit comprises a cutting edge, and, wherein said welding unit is configured to perform simultaneous transverse welding and cutting of said tubular web, said welding unit comprising a single operation surface performing said transverse welding and cutting.
