ABSTRACT:
An improved method for the automatic packing of articles in which bag sections are successively made of tubular plastics bag material which is intermittently conveyed. Goods are charged into a bag section formed at the leading end of the bag material. Thereafter the goods-charged bag section is heat-sealed at an opening portion thereof and separated from a subsequent bag section of the bag material. In accordance with the invention, before charging the bag section with goods, a piece of reinforcing sheet is inserted in and secured to the foremost bag section to form a reinforced handle portion having an opening for suspension of the finished bag.
