  • Patent number: 5160570
    Abstract: An apparatus and method for high speed placement of labels onto containers by a continuous motion. The label stock is transferred to a rotary vacuum drum, carried by rotation of the vacuum drum to a glue application station and then to a label application station where the glue coated labels are wrapped onto containers. As the containers reach the labeling position they are already rotating so that their surfaces are moving at the same speed as the drum surface. The labeled containers are then discharged onto a conveyor where they are held against rotation and stabilized by a pair of parallel belt drives.Glue is imprinted onto each label by a roller with a patterned surface. The roller picks up glue as it rotates past a glue bar surface which emits glue from a tapered exit. The tapered configuration causes build up of suitable pressure so as to force the glue into the pattern on the glue roller. A downstream edge of the glue bar surface acts as a doctor to spread and wipe off excess glue.

  • Patent number: 5137758
    Abstract: An automated coating apparatus includes a coating unit for applying a curable liquid material to the entire edge-to-edge surface area of one side of a flexible sheet. The sheet is then received on a rotatable drum adjacent the curing device, and moved back and forth next to the curing device to cure the liquid material. The drum includes a plurality of apertures in communication with a regenerative blower for retaining the sheet on the drum during the curing operation without contacting the uncured liquid material on the opposite face of the sheet. The curvature of the drum functions to essentially counteract the tendency of the sheet to curl during the curing operation.

  • Patent number: 5062918
    Abstract: A labelling machine is for bottles, or the like, and includes a rotatable drive shaft. The drive shaft has an axis of rotation and includes at least one radially extending surface which is disposed at a predetermined location axially on the drive shaft. The labelling machine includes at least one glue segment having a curved glue take-up surface. The glue segment includes a hole for receipt of the drive shaft within the hole. The glue segment is for being disposed within the hole receiving the drive shaft and for rotation with the drive shaft. The glue segment includes an axial bore having a longitudinal axis. The hole includes a longitudinal axis. The longitudinal axis of the bore is substantially parallel with the longitudinal axis of the hole and with the axis of the drive shaft when the drive shaft is disposed within the hole. A bushing includes a bases element and a spacing element. The base element of the bushing is for being disposed in the bore of the glue segment.

  • Patent number: 5045140
    Abstract: An apparatus and method for high speed placement of labels onto containers by a continuous motion. The label stock is transferred to a rotary vacuum drum, carried by rotation of the vacuum drum to a glue application station and then to a label application station where the glue coated labels are wrapped onto containers. As the containers reach the labeling position they are already rotating so that their surfaces are moving at the same speed as the drum surface. The labeled containers are then discharged onto a conveyor where they are held against rotation and stabilized by a pair of parallel belt drives.Glue is imprinted onto each label by a roller with a patterned surface. The roller picks up glue as it rotates past a glue bar surface which emits glue from a tapered exit. The tapered configuration causes build up of suitable pressure so as to force the glue into the pattern on the glue roller. A downstream edge of the glue bar surface acts as a doctor to spread and wipe off excess glue.

  • Patent number: 5017261
    Abstract: A labelling machine for bottles or the like includes several stations located behind one another along a track. The stations include an adhesive application station, a label feed station and a label transfer station. There are three extracting elements which are each mounted to rotate on a rotating support to be moved past the stations during each rotation of the support. Each extracting element has an outwardly-curved receptacle surface for the label which rolls along the stations. The drive for each extracting element is a cam drive, which comprises common, stationary double cam discs for all the extracting elements with two cams located on one side in two planes with one above and at some distance from the other. Two sets of followers are mounted on a bearing shaft which is coupled with the rotating support. By means of a form-fit with the two cams, the followers provide positive movement of each extracting element over its entire revolution when the support rotates.

    Abstract: Mounting and drive coupling for the extracting element support of a labelling station for a labelling machine. The mounting of the table which supports the extracting elements is positioned exclusively on the outer edge of the table, while the coupling between the table and the central drive shaft is located in the central space between the transmission and drive mechanisms and above the transmission elements. An alignment marking disc and marking wheel are included to assist in relatively positioning the extracting element with the support shaft.

  • Patent number: 4913081
    Abstract: A device for aspirating coating material, such as paints, from the applicator gap between two applicator rollers provides two suction tubes, which are disposed horizontally displaceably and whose outlet ends communicate with an apparatus for generating a suction pressure as well as with in apparatus for collecting the aspirated coating material. Particularly when a photoresist is applied to a board-like substrate in the manufacture of printed circuit boards, accumulations of the coating material in the region of the edge of the substrate passing through the apparatus can be avoided without mechanically straining the applicator rollers. By means of the suction pressure apparatus, the quantity of coating material accumulating as the boards to be coated pass through the apparatus can be aspirated continuously and returned via a collection tank to the supply of coating material to be used.

  • Patent number: 4781785
    Abstract: In the application of a solvent to a plastic label carried on the surface of a vacuum drum, the solvent for the plastic label is transferred from a gravure roll to the label at finite areas on the label so that the label can adhere to the bottle to be labeled and to itself to form a complete sleeve label. The gravure roll is supplied from a fountain block with a part cylindrical face that engages the gravure roll in face to face contact. The fountain block is retained in a holder with spaced adjustment devices for adjusting the position of the fountain block in the holder.The fountain block holder is pivotally attached to each of a pair of spaced apart plates about a first axis and the pair of spaced apart plates are pivotally attached to a second pair of spaced apart plates about a second axis which is spaced from and extends parallel to the first axis.

  • Patent number: 4772354
    Abstract: A solvent applicating roll, mounted for rotation about its vertical axis for transferring a solvent from etched or gravure areas on the roll surface to plastic labels that are moved into rolling contact with the roll, has its temperature controlled. The roll is formed as a hollow cylinder with heated air fed to the interior thereof to heat the roll to keep the solvent at a working temperature and prevent evaporative cooling of the roll due to solvent evaporating from the surface during operation. The heated air is passed through a distributor that assures the heated air will effectively transfer its heat to the metal roll.
