Filed:

Jul 19, 1984

Appl. No.:

6/632377

Inventors:

James W. Hodnett - Columbia LA

Assignee:

Ouachita Machine Works, Inc. - West Monroe LA

International Classification:

B65B 6102
B65B 5102
B65B 5118

US Classification:

53128

Abstract:

A novel bag machine and method for sealing a novel bag is disclosed. The bag is formed by positioning adjacent end surfaces of the bag tightly together and forming a plurality of tab structures on the ends of the bag which are turned against at least one of the end surfaces of the bag to lie flush therewith. Adhesive is applied to the area of the end surfaces and the tab structures and reinforcing tape is positioned over the adhesive and over the adjacent end surfaces to cover the turned tabs. The novel machine comprises a conveyor and a perforator assembly for conveying the bag and perforating the plurality of tab structures in combination with a tab turner to turn the tabs against one of the ends of the bag. Adhesive and reinforcing tape then are introduced into the sequence after which a cut-off and a pressure group complete the sequential operation of the machine. The method for applying adhesive to both sides of adjacent surfaces on a bag or similar material is also disclosed.

Quachita Machine Works, Inc. - West Monroe LA

International Classification:

B65B 1104
B65B 1304

US Classification:

53399

Abstract:

For enveloping a composite group of items in a stretchable film, a pair of initially spaced wrapping cage assemblies are moved inwardly toward each other so as to form a wrapping cage for supporting the composite group of items to be wrapped and for capturing a part of an elongated stretchable film between parts of the wrapping cage and of the composite group of items, rotating the wrapping cage assemblies so as to cause the stretchable film to envelop the composite group of items, withdrawing the wrapping cage assemblies outwardly so as to disengage the film and the composite group of items about which the stretchable film is wrapped and finally severing the stretchable film.

US Classification:

Abstract:

An improved in-feed method for, for example, the final closing stage of a bag filling machine of the type wherein a plurality of open bags with pre-formed gusseted tops are filled with a load of loose material and the gusseted tops reformed in a rapid sequence, and the bags are subsequently sealed closed. In the inventive method one bag pushes off the preceding bag in face-to-face engagement therewith along their front and rear sides, respectively, whereby the following or pushing bag being fed in is constrained on all four sides before it begins its infeeding movement. The four-sided constraint is provided by a multiple-finger pusher in the rear, opposing guides on the sides, and the presence of the preceding bag in front in face-to-face engagement therewith. Such frontal engagement prevents the load in the intermediate, following bag from shifting forwardly under the forward force of the pusher and opening the reformed gusseted bag top. The novel in-feed method takes place at the entrance to the bag closing station and is used in combination with an in-feed mechanism having a pivoted, movable inlet portion which initially presents open, tapered contact surfaces (FIG.

International Classification:

B65B 104

US Classification:

141 10

Abstract:

An improved filling machine of the type having an expanding fill spout comprising at least two split sleeves pivotally mounted around a circular filling spout. The improved filling machine also contains new and novel automatic means for holding the bag on the fill spout and means for detecting the presence or absence of a bag on the fill spout. The split sleeves and the means for holding the bag on the fill spout are interconnected by means of levers and other mechanical connections for unit operation by at least one power cylinder or other power means. .
