  • Patent number: 4978415
    Abstract: The invention provides a method for applying labels to articles moved one by one past an application station. The labels are cut from a web which is fed through the machine, the web having adhesive applied to one side thereof which is pressure sensitive immediately before application to the articles. The machine includes cutting rollers which cuts through the adhesive side of the web in order to sever the labels therefrom, and the cutting edges of the cutting roller are kept clean by applying thereto liquid silicone or the like release composition. The liquid silicone is preferably applied by means of sleeves impregnated with the liquid silicone, such sleeves being rotatable on a spindle which is parallel to the axis of rotation of the cutting roller.The machine also has gearing coupling a device for feeding the web of materials to the cutting location. The cut labels are held by a vacuum drum before being applied to the articles and the gearing is also coupled to said vacuum drum.

  • Patent number: 4886680
    Abstract: The invention provides a coating method and machine for applying pressure sensitive adhesive to one side of a web and release material in the form of a silicone coating to the other side of the web. The web is printed in rows of labels and is cut into the rows before being wound up after the coating process. The machine can also be used for transfer coating the adhesive onto the web by passing a release web through the adhesive applicator. Also, the machine can be used for making laminated webs. The machine has novel constructions of adhesive and silicone aplicators and curing devices.

  • Patent number: 4798648
    Abstract: An article feeding device is disclosed which comprises a straight scroll for feeding articles held between the scroll flights one by one along a straight path. A star wheel having peripheral pockets is arranged so that the wheel lies approximately tangentially to the scroll and rotates as the scroll turns. By this means, the articles are engaged in the star wheel pockets and are moved slightly away from the scroll at which point labels are applied thereto, and then the articles are returned to the scroll and released from the star wheel for continued feeding by the scroll.

  • Patent number: 4793891
    Abstract: The invention provides that labels are applied to containers. The labels have a pressure sensitive side and they are applied by a machine so as to lie tangentially to the bottle necks. The bottles then move through the machine and as they so move, a camming means which moves with the bottle engages the label and wraps it round the bottle neck. The camming means comprises a pair of arms which operate scissor like but in sequence as the bottles move through the machine.

  • Patent number: 4786046
    Abstract: The invention provides that a vacuum drum with rows of vacuum ports over its surface is used to transport self adhesive labels from a first location at which the labels are applied (adhesive surface outwards) to the drum to a second location at which the labels are detached from the drum. The labels are held to the drum during the transport by applying vacuum to the ports until the label reaches the second location, when the first and second rows of ports at the leading edge of the label are applied with air under pressure, the pressure of the air supplied to the second row of ports being less than that supplied to the first row and slightly in advance in the time sequence, so that the edge of the label is slightly inwardly of the adjacent label extremity, initially lifted from the drum and then the extremity is blown sharply away from the drum providing effective, positive and reliable detachment of the labels from the drum.
