Rollers on adjacent shafts are closely spaced apart and are axially offset relative to one another. Filling bodies are positioned between laterally adjacent rollers. Narrow gaps are provided between the rollers and the support bearing strips, between the filling bodies and the press belts, and between the rollers and the heating plate so that the lubricant can be moved through the gaps from the inlet side to the outlet side of the roller bed.

Abstract: The labeling machine comprises a stationary label hopper, a rotatable turret provided with suction means located adjacent to the leading edge of the terminal label in the article and constructed to enter into the hopper to lift by vacuum the leading edge of the terminal label out of the hopper and then in coaction with a pressure roll to mechanically withdraw the remainder of the label from the hopper and insert such leading label edge into the entry end of a fixed label guideway. Located intermediate the ends of the guideway and clamping the label in the guideway therebetween are a feed roll and a pressure roll spaced from the turret a distance substantially less than the length of the label so that they clamp the label before it moves past the turret and its associated pressure roll. Positioned adjacent to the discharge end of said guideway is a rotatable glue roll onto which the label is directed as it is discharged from said guideway.

Abstract: In an elastic band applicator for diapers using hot melt glue, a longitudinally tensioned moving plastic backing sheet is run over a roll that is parallel to and spaced from a stationary cylinder. A shoe deflects the central region of the sheet away from its plane at a location between the roll and cylinder. This results in the margins of the sheet beyond opposite ends of the shoe becoming loose flaps. Glue stripes are applied by means of nozzles to the sheet near its edges before the sheet encounters the shoe which has passageways for the glue stripes. Elastic bands are fed into the passageways onto the glue stripes. After passing the shoe, the margins encounter plows which turn or fold the margins over the glue stripes and bands and press the sheet against a cylinder to smooth the margin. Means are provided for retracting the sheet away from the hot nozzles if the sheet stops moving.

Abstract: A pair of sheets (46 and 48) are held by vacuum on a pair of spaced drums (30 and 32). A rigid board (51) is moved between the drums (30 and 32) whereafter the drums are moved toward each other to adhesively attach leading edges of the sheets (46 and 48) to opposite sides of a leading edge (50) of the rigid board. As the board (51) is moved away from the drums (30 and 32), the drums are indexed to release successive sections of the sheets (46 and 48) which extends the sheets in a wrinkle-free condition. As the board (51) continues to be moved away from the drums (30 and 32), the successive sections of the sheets (46 and 48) are maintained spacially from the board and in the wrinkle-free condition by various facilities such as a vacuum shoe (52), a shelf (53), a vacuum tensioning tube (56) and vacuum bars (57 and 58). Eventually, the wrinkle-free successive sections of the sheets (46 and 48) are brought into engagement with the board (51) and attached thereto by laminating rollers (59 and 60).

Abstract: A labeling mechanism is provided which utilizes a servo motor driven capstan to rapidly accelerate and decelerate label stock through the mechanism. Rapid acceleration is permitted because a secondary motor is provided to a label stock supply reel to reduce system inertia. Rapid deceleration is possible because a one-way bearing and clutch assembly is provided which prevents reverse motion of the label stock. A label shear is also provided which permits the use of continuous label stock rather than die cut, spaced labels.

Abstract: An apparatus for C-folding a running length of a covering web such as a polyethylene ribbon about a longitudinally flexible article such as a running length of a core web for making disposable diapers or a stream of longitudinally spaced discrete core segments of such a core web; i.e., a stream of absorbent cores for disposable diapers. The apparatus effects folding each longitudinal edge portion of a covering web downwardly and inwardly about an adjacent longitudinal edge region of the article as the web and the article are forwarded through the apparatus. Each longitudinal edge portion is so folded intermediate a transverse turning member which it passes under, and an oblique turning edge disposed downstream therefrom and over which it passes; and the longitudinal edge portions of the running web and the adjacent longitudinal edge regions of the article become juxtaposed upon passing over their respective oblique folding edges.

Abstract: Apparatus for securing a synthetic thermoplastic strap in a band-like form around an object includes a strap support with a clamping device, a stretching device, and a welding device cooperating with the strap support for holding, stretching, welding and cutting the strap. These various devices can be displaced from the surface of the strap support so that the strap can be inserted laterally onto the support. Strap guidance members are provided at the opposite ends of the strap support. One strap guidance member forms a part of the welding device and includes a guide member. The guide member is retractable away from the surface of the strap support during the welding operation so that it does not interfere with the movement of the strap parts being joined together.

Abstract: In acoustic panels employing a layer of perforate metal adhesively bonded to a layer of porous fibrous metal of a different type with the perforations of the perforated layer and the pores of the porous fibrous layers open to communication therethrough and the layers being isolated therebetween. The isolation between the layers is maintained by applying a coating of liquid epoxy resin material to selected locations, curing the epoxy coating, cutting or drilling the layers as required, and recoating the cut or drilled areas with a second coating of liquid epoxy resin.

Abstract: A desired decorative design on packaging such as tubes is made up of a combination of printed matter and a decorative foil such as a metal, pigmented or textured pattern foil. The method involves the steps of first applying the printed matter to the material with an ink treated to prevent adherence of the foil to the printed matter. Thereafter, the foil coated with an adhesive is positioned against the material and heat and/or pressure applied so that a foil transfer will occur onto all areas of the material engaged by the foil that are devoid of the printed matter. The foil is applied with a smooth continuous silicone pad. Exact registration is assured and the use of complicated die designs is wholly avoided.
