Heat-sealing device for sheet packages

摘要

A heat-sealing device for sheet packages includes: a pressure heat-sealing part that presses and heat seals a lid unit component placed on a moving bag-forming film; a heat-sealing mechanism having a frame body to support the pressure heat-sealing part; a drive mechanism having a linear motor that serves as a drive source to move the heat-sealing mechanism back and forth; and a link mechanism that links the two mechanisms, wherein the heat-sealing mechanism includes double heat-sealing mechanisms having two units of the heat-sealing mechanism installed side by side in parallel at positions vertical to the moving direction of the bag-forming film.
