摘要： A plastic bag making machine includes a cylindrical drum with a variable diameter. A plurality of seal bars define the circumference of the drum, and are substantially parallel to the drum's rotational axis. The bags are made from a plastic film with registration marks that are detected by a detector disposed near the film. A detector also detects each revolution of the drum and an encoder provides signals indicative of the position of the film. A controller determines the distance phase of the registration marks and the rum size error. The drum diameter is adjusted in response to an output of the controller in such a way as to correct for both the initial drum size error, the initial phase error, and the phase error accumulated while the drum diameter is being corrected.

摘要： The rotary bag making machine of the present invention is adapted to make side seal bags having a plastic drawstring through a hem in the top of the bag. More specifically. The rotary bag machine of the present invention includes a two part, elongate sealing bar having sealing edges, the first part of which is heated to a first temperature for sealing two layers of plastic bag material and the second part of which is heated to a second higher temperature for sealing the six layers which are present when hems are formed with inserted drawstrings. The second part of the seal bar is not only designed to form the seal but to heat weld together the drawstring plastic so that it will not separate or tear apart when the bag is gathered and subsequently tied with the drawstring.

摘要： A winder for making coreless rolls of pliable sheet material, such as plastic, cloth or paper, includes a cut-off section for severing a continuous strip of feed material to the desired length and a conveyor system downstream thereof. A portion of the conveyor is pivotable between a first and second position to feed spaced-apart winding rod assemblies. The rod assemblies each include a pair of elongate, spaced-apart rods and a mechanism for rotating the pair of rods to wrap the feed material into a coreless roll. The rod assemblies also include a system for collapsing one of the two rods toward the other when the winding of the roll is completed and it is desired to dispense the coreless roll. A finger mechanism is also provided for properly orienting the pair of rods to receive the leading end of the pliable material. By employing multiple winding assemblies and the pivotable conveyor system, the speed of the winder can be substantially increased. The present invention is especially suitable for the winding of rolls of dropcloth or other cover-sheet materials.

摘要： This invention pertains to draw tape equipment, and methods for incorporating draw tapes into plastic and like bags. In general, a continuous plastic web is slit at a slitting station to form layers, and respective free edges. The web then passes to a hole forming station where holes are punched in the top and bottom layers adjacent the free edges. After the holes are punched, edge regions of the top and bottom layers are separated from each other, followed by forming of hems in the separated layers at hem forming stations arranged in parallel with each other. Concurrent with forming of the hems, continuous draw tapes are fed to the hem forming stations and the hems are formed about the draw tapes. The formed hems, with the draw tapes incorporated therein, optionally pass through first temperature control stations where the temperature of the plastic web is controlled to a desired temperature before hem sealing. The formed hems are then sealed to the main bodies of the respective top and bottom layers. Narrow pressure wheels apply pressure to the hot seals to improve seal quality. The sealed hems optionally pass through second temperature control stations to cool the web. The edge regions of the layers are then rejoined, in face-to-face relationship with each other.

摘要： A method and apparatus for winding film includes guiding a strip of the film through a winding machine to a rotating spindle. At least one deflector and/or at least one source of air, such as a nozzle, is moved to the path of the film downstream from the spindle, and an airhorn is moved to the spindle. The leading edge of the strip is directed into the airhorn by the deflector and/or air from the nozzle, and then directed by air within the airhorn into its own nip. Finally, the strip is wound about the spindle.

摘要： A method and apparatus for registration of a seal and perforation on a plastic bag include a drum for forming a seal on a continuous plastic film with respect to a registration mark on the film and a perforator/cutting station for forming a perforation on the film with respect to the location of the seal. This method and apparatus is used in a plastic bag making machine to produce bags of different lengths. A detector locates the registration mark printed on the film and the drum diameter may be adjusted to form the seal at a desired location on the film with respect to the registration mark. A seal detecting station locates the seal and a controller adjusts the speed of the perforator/cutting station to properly locate the perforation with respect to the seal and to maintain a desired skirt length.
