Abstract
Abstract A device for packaging goods, such as in a supermarket and the like, is arranged to pack the goods in a flexible bag-like member held in an open position at a loading station and, after the loading operation is completed, the bag-like member is sealed and delivered to a pick-up station in an automatically performed operation. Belts convey the bag-like members individually to the loading station where the members are opened for carrying out the packing operation. Other belts convey the packed bag from the loading station to the pick-up station and at a point between the loading station and the pick-up station the mouth of the bag is sealed. A belt conveyor can be used to support the packed baglike member from the loading station to the pick-up station. The bag-like members are withdrawn from a supply roll containing a continuous strip of interconnected bag-like members which have a reinforced mouth and the bag-like members are formed from a folded over longitudinally extending strip of flexible film material welded together at spaced positions to form the individual bag-like member.
