Abstract: A method and apparatus for feeding resiliently compressed articles into a form/fill/seal machine. The method includes steps of receiving horizontally compressed articles into an infeed end of a pair of conveyor belts, continuously conveying the compressed articles to a discharge end, continuously forming a plastic film around the pair of cantilevered conveyor belts without the stack of articles exerting expansion force against the plastic film, forming and sealing a closed tube, and releasing the stack of compressed articles into the closed tube only after the seal has sufficient strength to maintain the stack of articles compressed. The pair of conveyor belts has rigid conveyor backing members and cantilevered ends with a discharge pulley mounted at each cantilevered end. At least one tie bar connects the backing members near the cantilevered ends in order to resist the expansion force of one or more stacks of resiliently compressed articles between the conveyor belts.

Abstract: An apparatus for enveloping successive groups of items in a plastic film as the items traverse a linear path. Items are gathered in a group, and the group of items is then inserted in a tubular packaging film as the items and the film are conveyed at the same linear velocity. After the items are completely enveloped in the film, the film is severed and sealed to fully encapsulate them in the film. A vacuum is used to eliminate excess air generated within the tube, and also, in one form of the invention, form side gussets as sealing dies are closed. A tight package made at speeds results, with no need for any holes in the film to relieve internal air pressure.

Abstract: A continuous web of wrapping material for catamenial tampons or other commodities is advanced lengthwise first through a station where it is acted upon by a perforating knife to weaken longitudinally spaced-apart portions of the web transversely of the direction of advancement. The web is thereupon converted into a continuous tubular body and the leader of the tubular body is engaged by a pair of rolls which pull the leader in the direction of lengthwise advancement of the web in order to break the material of the web along successive weakened portions. The thus obtained discrete tubular envelopes are moved sideways, one end portion of each envelope is closed, a commodity is introduced through the other end portion, and the other end portion is closed to confine the commodity at both ends. Such mode of making tubular envelopes ensures that the material of the web is not wasted at all and that the envelopes need not be stored prior to reception of commodities.

Abstract: The present invention relates to machines used to wrap objects or articles using a film sheet obtained from a reel. This machine uses a mechanism that adjusts to and fro movement of a connecting rod thereby limiting the length of the film to be used for wrapping the article or product. This mechanism includes a connecting rod (6) capable of to and fro movement in response to the swinging movement of a lever (1) that is set off by a cam (2). The connecting rod (6) has a lateral part (8) with a pulley wheel (9) that runs along a groove (10) within a guide (11). The guide has an articulation (12) that is jointed to the chassis (13) of the machine, in such a way that an adjustment in a swinging position of the guide (11) limits the to and fro movement of the connecting rod (6) and thus the mechanism connected to the connecting rod will carry on the drive and sectioning of the film to be used as a wrapper.

Abstract: A product required to be kept in a clean environment is packaged by removing outer layers of a multi-layer film and immediately thereafter introducing its inner core sheet inside a clean room. A bag with an opening is produced inside the clean room by superposing and sealing together two of such core sheets, by splitting one core sheet into two sub-layers and superposing and sealing together these two sub-layers or by folding one core sheet and superposing and sealing together its folded parts. The product may be packaged in such a bag either by using the same apparatus which makes the bag or by using another apparatus. The bag is made of a multi-layered material, and its outer layer is peeled off immediately before it is put inside a clean room to be torn apart and to have the produce taken out.

Abstract: A form fill packaging and sealing apparatus comprises a film dispenser and a film forming plow which, together with a roller guide, forms the film to be sealed into a tube with the free edges at the side. The object to be packaged is inserted into the film tube. The free edges of the film are longitudinally sealed together at the side of the package by a rotary heat sealer and immediately cooled to approximate impulse sealing. The quality and width of the longitudinal seal can be adjusted by changing the amount that the film is preheated before sealing. A cross seal is made at the front and back of the object to be packaged. The excess gas in the package is pressed out by a presser before the back cross seal is made.

Abstract: Due to variations in the thickness of the film used in wrapping packaged product and various other reasons, the wrapping film such as polyethylene, polypropylene, etc., occasionally causes uneven pulling on the film with resultant turning around or twisting of the film on the packaged product, which causes a breakdown in the wrapping operation. Such breakdowns are avoided by placing on each side of the film wrapping apparatus, a film tracking, preferably electrostatic, probe appropriately spaced from the film so as to position an electrostatic charge thereon. If the film tries to creep sideways, one side of the film is exposed much more to the static generating cone on that side and less on the other. The resultant static friction forces built up on one side of the film and less on the opposite side cause the film to creep towards the side with less static friction build up until the static forces on both sides become equal and cure or avoid the twisting procedure.

Abstract: A thermal shrink film is continuously pulled out and is shaped into a tubular form. Individual items to be wrapped are fed into the tubular film sequentially and overlapping marginal portions of the tubular film extending lengthwise are sealed.

Then the tubular film is sealed and cut transversely of each item at the rear end thereof to form an intermediate package. The film of the intermediate package is shrunk by heating to thus shrink-wrap the item.
