To align two webs, which are joined together to form a multilayered web and of which one web exhibits a certain elasticity, this web is held under a stress, which elongates elasticly said web. The tension is increased or decreased in conformity with the deviation of the scanned marks of the web from the desired values so that by suitable elongation or shortening the web is aligned with respect to the other.

A form-stable panel element, such as an automobile ceiling headliner, includes two layers of pyramid frustum-shaped cups that are intermeshed with each other, and two cover layers that close and seal hollow chambers in each of the cups. Each chamber is filled with a filler material that may be a loose mixed granulate of waste or recycled polymer. All of the layers are thermally fused and laminated integrally together. The panel element may be molded into a three-dimensional contour. The panel element is strong, lightweight, stiff against bending, incorporates waste or recycled materials, and provides good noise damping.

Methods and apparatuses for inserting flexible bags and other liners into open packaging containers. One or more engagement heads engage and position the flexible liners in preparation for their insertion into open containers using an insertion assembly. One or more of the engagement heads are preferably made with vacuum heads that are movable to open the liner for the insertion assembly. A cuffing assembly can be included for cuffing the open end of the liners over the top edges of the open containers. Clamping assemblies can be included on the cuffing assembly to facilitate holding the liners during insertion and cuffing. The use of an engagement assembly, insertion assembly, and cuffing assembly which are independently driven helps to provide greater speed and operational flexibility.

A gabled, gussetted resealable lined container having an outer carton with foldable closure flaps and a liner within the carton. The upper inner surfaces of the liner are releasably sealed together after filling with product and at least one of the liner upper outer edges adhered to the closure flaps on the carton, whereby when the closure flaps are opened, the inner liner is pulled opened and when the closure flaps are closed, the inner liner is resealed to maintain product freshness.

A bag capable of displaying and protecting an item during shipping, transportation, handling and/or display. The bag is fabricated from at least one sheet of material which is formed into a tubular sheath having a heat-sealable bonding material disposed solely on portions of the tubular sheath of material so as to bondingly hold the tubular sheath of material in a bag-like configuration. The portions of the tubular sheath having the heat-sealable bonding material thereon may be configured as either lap or fin seals or combinations thereof. There is also provided methods for producing such a bag and methods for its use.

Flaps, tucks, panels, tabs, walls and analogous parts of paper or cardboard blanks which are to be converted into packets, cartons or otherwise configurated receptacles for smokers' products are bonded to each other by patches, strips or otherwise configurated films or layers of adhesive which is applied to a surface of a first part and is to bond the first part to a second part of a blank. In order to accelerate the setting of adhesive, the movement of one of the first and second parts into engagement with the other of such parts is effected by at least one ultrasonic atomizer for the adhesive. The atomizer can be stationary if the blank is advanced relative to the atomizer by a conveyor and/or vice versa.

Methods and apparatuses for inserting flexible bags into open containers, and cuffing an open end of the flexible bags about a top edge of the open containers. The method and apparatus include a vacuum assembly having at least one movable vacuum head for engaging and positioning the flexible bags in preparation for their insertion into the open containers. An insertion assembly having a mandrel inserts the flexible bags into the open containers. A cuffing assembly can be included for cuffing the open end of the flexible bags over the top edges of the open containers. The vacuum assembly may engage a flexible bag from a bag dispenser while the mandrel is in an extended position within the container. The method and apparatus also facilitate the use of a vacuum assembly, insertion assembly, and cuffing assembly which are independently driven to provide greater speed and flexibility to the bag opening, insertion and cuffing processes.

A method for making a cigarette container wherein a hollow container body is constructed having an open end which includes a step portion defining a surrounding rim and interior abutments. A plug is prepared which is sized to be received between the rim of the body and to abut the abutments. The plug includes a main plate, a metal layer attached to the main plate, and a heat activated adhesive located adjacent the metal layer and positioned to be immediately adjacent the step portion. An induction heating device is then located adjacent the open end of the body, and activated to heat the metal layer and hence to heat the adjacent adhesive so that after cooling the plug is bonded to the body by the adhesive and the plug thus permanently closes the open end of the body.

A substantially planar packaging device including printed indicia and defining a closed cavity being suitable for containing at least one product. The substantially planar packaging device including a first sheet forming the closed cavity, and a second sheet at least partially detachably coupled to the first sheet to allow the second sheet to be at least partially detached from the first sheet to view at least a portion of the indicia and reattached to the first sheet.

The invention is a method of forming Bliss-type boxes by combining containerboard body blanks with end panel or box liner blanks. A Bliss box former is used in direct association with a slitter scorer. The slitter scorer is supplied with containerboard sheets having a width which is equal to the length of the box liner blanks. The sheets have a length which is equal to a whole number multiple of the width of the box liner blanks. Box liners are severed and scored one-by-one as needed by the Bliss box former. This reduces the need for maintaining multiple sizes of box liner blanks in inventory and greatly simplifies setup when boxes are being made that differ only in width.
