| A trifold side seamed film produce bag includes a front wall and a back wall, first and second side edges sealed together and a seamless bag bottom. The bag is joined at the side edges to additional bags by a perforation. The bag is corona treated on at least one wall and promotional material is printed on the treated surface. The bags are folded to one third of their height to fit compact bag roll dispensers. The bags are folded in a Z-fold or C-fold configuration. The method includes manufacturing the bags and winding them onto cores or forming the bags into coreless rolls. An apparatus for forming the side seamed bags includes an extruder, a tubing flattener, a perforator, a sealer, a corona treater, a printer and a slitter. The treated, printed bags may be stored on rolls for later slitting into two bag streams and folding into thirds. | ||||||

| Reclosable bags, plastic film for making the bags, and a method and apparatus for making the bags are disclosed. The bag has a reclosable fastener (26) connected to a single wall of the bag, and the film (55) has a reclosable fastener (26) connected to one side thereof which does not require attachment to any other portion of the film (55) when making a bag. The fastener (26) has a tamper-proof member attached thereto to indicate if the bag has been previously opened. The film (55) can be wound into a roll (54) suitable for use on conventional bag making machines including form, fill, and seal machines or a chain of coilable reclosable bags can be produced therefrom since the fasteners (26) are connected to the web preferably transversely to the bags longitudinal formation axis. The method and apparatus for making the film (55) includes supplying a continuous web of bag making material, feeding from a coil of continuous fastener material enough fastener material to make a single fastener, (26) positioning, cutting, and attaching the fastener (26) to the film (55), with a plurality of fasteners (26) attached thereon. | ||||||

| A multi-ply plastic bag from a continuous strip of bags on a roll is supplied to a user with the top of the bag partially opened. A tear line between the bottom of a leading bag and a top of a subsequent bag separates the individual bags. A broad slit centrally located in the tear line passes through all but one ply of the strip of bags. The bag dispenser has an upwardly projecting tongue which engages the slit in the tear line when a user draws a bag from the dispenser. The tongue impedes the subsequent bag from moving forward. The adjacent bags separate along the tear line. The ply which does not have a slit rides over the tongue and pulls apart the plies at the opening of the subsequent bag before the leading bag completely separates from the subsequent bag. | ||||||

| A coil of an interconnected chain of open bags is provided in which the coil has a center opening having a diameter at least as great as the transverse dimension of the bags. A dispenser is provided on which a coil of bags is mounted. An end of the chain is pulled from the center opening and fed around a tapered mandrel and thence over a feed control mandrel oriented in angular relationship with the tapered mandrel. The web is then fed to a bagging machine for dispensing, loading and closing of the bags. The table on which the coil is mounted is rotatable so that the orientation of a span of bags running from the coil to the tapered mandrel remains substantially constant as the web is fed. | ||||||

| 11 | Apparatus for detaching pieces of tube provided with transverse weld seams from a web and for stacking the same | US982662 | 1992-11-25 | US5312317A | 1994-05-17 | Hans-Ludwig Voss; Andreas Schroedter; Uwe Koehn |
| An apparatus for providing transverse weld seams and transverse detaching cuts or for providing detaching weld seams on a tubular or semi-tubular web of thermoplastic synthetic resin, and for stacking the detached sections includes a transverse welding and transverse detaching station for detaching sections having bottom weld seams and any leading head weld seams from the web and a stacking station for retaining or fixing the supplied sections. The web is moved intermittently. To cool the trailing weld seams of the sections without causing the sections to stick together adjacent to the bottom weld seams during stacking, a drum is provided which rotates about a transverse axis between the transverse welding and transverse detaching station and the stacking station. The wall of the drum includes at least two wall parts. The drum is adapted to be driven in step with the welding process by rotating the drum through an angular increment related to the number of wall parts of the drum in each revolution. In synchronization with stacking the cut sections at the stacking station, a path is formed for allowing the web to be pushed through gaps between the wall parts of the drum between the transverse welding and the transverse detaching station and the stacking station. | ||||||

| The invention relates to a method for making bags preferably provided with side folds or other flat workpieces, which have a slip extending beyond their boundary. In accordance with the invention partly prefabricated bags are laterally supplied to a conveyor belt driven in a timed manner, and are seized there by grippers and fixed. By means of a glue applicator a glue strip is applied to the bag in its bottom region during the timed feeding movement of the conveyor belt. Finally, in a slip application station a slip is supplied each laterally to the conveyor belt and is placed onto the glue surface. The invention furthermore relates to an apparatus for carrying out the aforementioned method. | ||||||

| Disclosed is a bag including a front wall and a rear wall and having an open mouth portion in which the front wall and rear wall are joined by pleated portions or gussets. The bag is manufactured so that a longitudinal, thermally welded seam is placed inside a portion of at least one of the gussets at a point other than the central fold. The bag preferably includes handles which are integral extensions of the front and rear walls and the gussets. The bag manufactured according to the principles of the present invention thus eliminates or minimizes failure of thermally welded seams.Also disclosed is a method for manufacturing the bags and an apparatus for manufacturing the bags. | ||||||
| 16 | Apparatus for making bags or sacks from a preferably gusseted continuous tubular film of thermoplastic plastic | US190442 | 1988-05-05 | US4913765A | 1990-04-03 | Konrad Tetenborg; Helmut Huwelmann |
| An apparatus is disclosed for making bags or sacks from a continuous tubular film of thermoplastic material. The continuous tubular film is moved intermittently in a downward direction to a welding device, a cutter below the welding device, and a turret-like rotary conveyor below the cutter. A bag length is received by grippers on the rotary conveyor before it is welded and cut. When thus received the bag length is welded and cut, and the conveyor indexed by one step to present succeeding grippers to the tube. The tube is then advanced another bag length so that the succeeding bag is received in the succeeding pair of grippers. The process is repeated with succeeding bags. The bags on the conveyor are successively delivered to a transfer station where the grippers are opened to release the bags. | ||||||
| 17 | Apparatus for manufacturing bags made of plastic material | US221203 | 1988-07-19 | US4871346A | 1989-10-03 | Louis Colin |
| The apparatus for manufacturing bags in plastic material comprises a welding assembly having a pair of fixed jaws and a jaw which is movable therebetween for clamping respective alternately advancing tubular bands made of plastic material. A cutting element, carried by a flexible belt rotatable on the movable jaw, is adapted to cut the bands upon clamping the movable jaw on the fixed jaws. An assembly for extracting and accumulating the bags is provided with a plurality of needles at each fixed jaw and actuated with reciprocating motion in the direction of sliding of the movable jaw so as to penetrate a bag clamped between the jaws. The apparatus also comprises a fork for placing the bag adjacent to the previously produced bags supported on the needles, and a slider for unloading a pack of manufactured bags. | ||||||
