FIELD: mechanical engineering.
SUBSTANCE: invention relates to packet making and sealing devices, particularly to such which fasten made packets of strip. Proposed device contains packet making unit, fastening unit which attaches packets made in unit to strip. Fastening unit contains transfer mechanism which directs packets made in unit diagonally downwards, and attachment mechanism which attaches packets to strip after transfer of packets by transfer mechanism. Proposed packet making and sealing device includes also cross welding mechanism to weld vertical ends of packets. Said mechanism contains pair of welding members gripping end of packet and applying heat and pressure to end of packet for welding during downwards movement. Said pair of welding elements releases end of packet in release position which is fixed in said device irrespective to distance through which pair of welding elements travels in downward direction with gripping of packet.
EFFECT: increased capacity of device, reduced height, facilitated adjustment or design of packet attachment mechanism.
