Abstract: A plastic container having a multilayer label applied by in-mold labeling during the blow molding of the plastic container. The label comprises a non-cellular inner layer, an intermediate cellular layer compatible with the inner layer and heat bonded to the inner layer, and an outer non-cellular plastic layer compatible with the intermediate cellular layer and heat bonded thereto. The label is positioned in a mold cavity with the outer layer in contact with the mold. When a hot plastic parison at molding temperature is expanded by fluid pressure against the walls of the mold to form a container, the noncellular inner layer becomes bonded to the outer surface of the container by heat from the container.

Abstract: A labeling machine for successively applying flexible plastic labels to round containers, such labeling machine incorporating equipment to sever labels from a web of indefinite length thereof, to apply a leading edge of each of such labels to the periphery of a rotating vacuum drum, heating the leading and trailing edges of each such label while on the rotating vacuum drum by directing warm air thereagainst to heat such leading and trailing edges to a temperature at which the material therein becomes self-adhesive, and bringing the heated leading edge of the label on the vacuum drum into contact with a container rolling along a curved surface at a label transfer station to cause the label to transfer to the container and to eventually wind itself around the rolling container, thereby causing the heated leading and trailing edges of the label to adhere to the container or, in the case of a label whose length exceeds the circumference of the container, to cause the trailing edge of the label to adhere to the ov

Abstract: A cathode ray tube faceplate press having an indexing table rotatable around a column normal to the table and having circular array of female molds concentric with the column. Index speed of the table is optimized by a barrel cam drive cut to provide smooth acceleration and deceleration which can be tolerated by the molten glass in the molds. A cam dwell precisely registers the table work stations avoiding the need for register pins and the delays they introduce. Acceleration and deceleration peak at about the one-eighth and seven-eighths position of the drive cycle following a generally sinusodial form.

Abstract: Apparatus and method for inspecting the finish of transparent containers, particularly glass containers, which include facility for directing diffused light energy laterally through the container finish as the container is rotated about its central axis. A camera includes a plurality of light sensitive elements disposed in a linear array angulated with respect to the container axis to view the external and internal finish wall surfaces, the latter through the open container mouth. Individual elements of the camera linear array are sampled by an information processor at increments of container rotation, and corresponding data indicative of light intensity at each element is stored in an array memory as a combined function of element number and scan increment. Such data is compared following completion of container rotation to standard data indicative of acceptable container finish, and a reject signal is generated if such comparison exceeds an operator adjustable threshold.

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 that is held against the roll under a spring force. The fountain is in the form of a plastic block which has a face that has several undercut channels in one of which the solvent is supplied and with the others acting as doctor channels to carry away any excess solvent from the roll surface.The fountain block is held by a vertical support plate that, in turn, is held to the surface of a vertical mounting plate by a quick release toggle clamp.

Abstract: A completely automated system for inspection and sorting of molded containers, such as glass bottles, as a function of mold cavity of container origin. In a first system section, finished containers are one hundred percent inspected for defects, and a cavity identification device is controlled to reject all containers from cavities associated with defective containers. The cavity identification device is also coupled to feed sampled containers from selected cavities to an automatic sampling indexer wherein the sampled containers are fed to one or more stations for testing physical container properties, such as rupture pressure, wall thickness and internal volume. The cavity identification device and the automatic sampling indexer are controlled by a hierarchy of interconnected computers which receive cavity and test information from the various sections and stations of the system and control the sampling and sorting process based upon predetermined quality standards.

Abstract: A cylindrical vacuum drum for carrying a label held to its surface by vacuum past an adhesive applying roll to a position where the label will touch a container and the container will be rolled along the drum surface to thereby apply the label about the container. The drum is formed of metal and is mounted for rotation about its vertical axis. The drum has a rubberlike covering thereover with at least two raised areas in the cover, which underlie the leading and trailing edge of a label that is at a greater radius than the rest of the surface. These are the areas which serve to press the label against the adhesive roll or solvent applying gravure roll. These areas have very slightly depressed zones forming slight steps just in advance thereof with a row of vacuum ports extending through the cover at the base of said steps to effectively hold the leading edge of the label down and allow the trailing edge to bend upwardly away from the outer surface of the drum.
