摘要： In a process for manufacturing sacks of sheet material, flat tubes are fed one by one in the direction perpendicular to the discharging direction thereof, while the tubes are overlapped or shingled as offset by a predetermined distance. The tubes are wound one by one on a reel core with the help of a tape, which is connected at one end thereof to the reel core and continuously supplied with the rotation of the reel core. The tubes are secured on the reel core outside pressure supplied by the tape to form a tube wound reel having a desired diameter. After a certain time period and immediately before the susequent bottom-closing process, the tubes are unwound from the reel core by pulling the tape to rotate the reel. The overlapped tubes are then separated from each other and supplied one by one to a bottom-closing station.

摘要： In a composite bag comprising an outer bag and an inner bag which is secured thereto by adhesive, the outer bag is provided with a cross-bottom folded closure at least at one end where no filling valve is provided. Adjacent said one end of the outer bag, the inner bag is closed by a weld seam and folded back on itself and secured in position so that, in a flattened condition of the composite bag when the cross-bottom folded closure lies snug against the bag body, the inner bag extends no further than the centre line of the cross-bottom closure.

摘要： A container is disclosed comprising a first sidewall having a first layer and a second layer. The second layer overlaps a portion of the first layer to define an overlap area. A sealing flange extends from the first layer outward of the overlap area. A second sidewall is connected to the first sidewall along the sealing flange to define an inner chamber therebetween. The second sidewall and the sealing flange define a first layered structure having a first number of layers along the sealing flange. The overlap area and the second sidewall define a second layered structure having a second number of layers. The second number of layers is greater than the first number of layers. The container is sealed by positioning peripheral edges of the first and second sidewalls into registration so that the overlap area is substantially centrally disposed over the second sidewall and applying sealing energy to the first number of layers to define a peripheral seam.

摘要： An apparatus and method for forming a sheet of material into an article, such as a flower pot cover, is provided. The apparatus includes a female die and a male die. A sheet of material is positioned between the male die and the female die. The male and female dies are shaped such that at least a portion of the male die is receivable in the opening of the female die to form the article. The apparatus further includes means for supplying a stream of air between the female die and the formed article to release the formed article from the female die and means for holding the formed article against the male die as the male die and the female die are positioned from a forming position to a discharge position whereby the formed article is removed from the female die.
