FIELD: process engineering.
SUBSTANCE: sealing clamp 1 to make packs from packing material sleeve 2 has structural case 11 and first working surface 27 interacting with second working surface 29 on opposite clamp 2 to grip material to be sealed and perform sealing. One 1 of clamps 1, 2 makes support 9 anile another clamp 2 makes heater 8. Clamp 1 has connector 30 to attach first surface 27 to structural case 11. Connector 30 makes curved third and curved fourth surfaces 31, 31 mage of stiff material to interact jointly to cause vibrations of first surface 27 relative to structural case 11 in gripping packing material before sealing.
EFFECT: controlled and repeater vibration of clamp bearing surface relative to second clamp support parallel with ultrasound radiator.
