Abstract

An apparatus for forming an article out of superimposed heat-sealable panels comprises a conveyor for moving a pair of superimposed webs along a path and into a cutting and sealing station whereat the panels are cut out of the webs and simultaneously heat-sealed together. The simultaneous cutting and sealing steps are effected by a unitary die having a cutting die that is heated to a predetermined cutting temperature and a sealing die that is heated to a predetermined sealing temperature that is substantially lower than the cutting temperature. The apparatus also includes steering means for automatically shifting a belt of the conveyor to maintain it in proper alignment and a scrap removal station for removing the web after the cutting and sealing operation.
