FIELD: process engineering.
SUBSTANCE: sealing element 15 comprises heater 20, 21 arranged for heat-sealing of packing material at spaced apart transverse sections of pipe 2 so that multiple sealed packages are produced. It includes groove 60 to interact with cutting element 62 arranged at counter-sealing element 16 in cutting. At cutting, sealed package 3 is separated from pipe 2. Sealing element 15 comprises at least one slit 70 extending between groove 60 and first outer wall 53, 54 of sealing element 15.
EFFECT: decreased risks of soldering element and/or cutting element damages, longer life.
