摘要： A method and apparatus for the automatic manufacture of flat bottom bags from a substantially continuous supply of a sealable material whereby the material is formed as a bag having a reinforced sealed flat bottom formed by an interior bag forming assembly that is cooperable with a relatively movable folder assembly that folds the bottom of the bag and removes it from the bag former assembly after a length of the bag is severed from the remainder of the material.

摘要： Flat bottom bags are formed from a supply of substantially endless plastic tubing, gusseted along two sides to form a flat reel. A sleeve of predetermined length is withdrawn from the reel and allowed to hang along a vertical plane between two foraminous plenum chambers which are then moved toward each other to squeeze the length therebetween. Simultaneously a sealing and shearing mechanism forms a transverse seal and cuts the sleeve length from the reel, the gussets being at the same time sealed in the seam. The plenum chambers are then subject to vacuum and are moved apart, causing the sides of the now formed bag to separate opening the same. Upon opening of the bag, a forming mandrel is inserted therein and moved through the length of the bag until it reaches the sealed end. Simultaneously a presser member is moved across the outside surface of the bag folding over the seam, and pressing the gusset portions into flat flaps and in addition forming simultaneously the flat bottom to the bag. The mandrel or the presser plate is provided with heat sealing means sealing the flaps to the sleeve sides.
