FIELD: manufacturing technology.
SUBSTANCE: tip assembly of the welding element for the rotary bag-making machine is described, including the tip, the welding zone, which comprises the separating layer that is situated over the mentioned tip, and the filament, which is introduced by means of stitches into the separating layer and into the tip, the tip assembly comprises the means for perforating. Filament can be made of NiCr wire. Softening zone can create the strength reduction line that can be uniform, or can have varying strength. Welding zone may include temperature zones, cartridge heaters, cooling air or heated air, or the source of ultrasonic, microwave or radiation energy.
EFFECT: provision of the improved capability for the perforation location near the welded seams.
