Abstract: Automotive trim strips are molded in an open-faced mold cavity by extruding a ribbon of plastic therein and moving a shaping roller thereover to compression mold the viewing surface of the trim strip into conformity with the surface of the mold cavity and to shape the non-viewing with the shaping roller.

Abstract: An improved decorative automotive vehicle trim strip and method and apparatus for forming by reshaping an end of a previously extruded length of thermoplastic material. The surface of the length of thermoplastic material intended for viewing is maintained at a cold temperature, well below the softening point of the thermoplastic material, during the reshaping operation. The length of thermoplastic material is heated during reshaping by a mold section heated 400.degree. to 410.degree. F. pressed against the surface intended to be affixed to the vehicle.

Abstract: A method and apparatus for delivering labels to the blow molds and removing blown containers with the labels thereon from a blow molding apparatus wherein the apparatus precludes access to the upper or lower ends of the molds. A carriage is reciprocated horizontally between a position externally of the blow molds and a position within the blow molds. The carriage supports pick-up heads that pick up labels from magazines, deliver them between the mold halves and deposit them on the mold halves. The carriage also supports container removal devices that engage the blown containers with the labels thereon and remove them from a position between the mold halves.

Abstract: In the forming of an article by blow molding a parison into conformity with a cavity defined by a partible a method and appartus which comprises positioning a label of flexible material on each section of the mold, each label having a width in a circumferential direction such that a portion of one axial edge of each label extends beyond the side edge of the cavity forming portions of the section of the mold and the other axial edge, moving the mold sections toward one another so that they close and define the mold cavity, deflecting the edge of each label radially inwardly before the molds close such that as the molds close the deflected edge will overlap with an adjacent edge of the adjacent label, and blowing the parison into conformity with the cavity such that the edges of the two labels overlap and register to define a continuous label about the article.

Abstract: A process is disclosed for extruding heavy tubular shaped articles from high molecular weight, high density linear ethylene polymers under shearstress conditions such that the exterior surface of the extruded article would undergo melt fracture. Melt fracture is avoided by coextruding a thin layer of a second ethylene polymer in contact with the high molecular weight, high density linear ethylene polymer and the outer lip of the annular die. The second ethylene polymer has melt flow properties such that it does not exhibit melt fracture at the temperature and shear rate employed in extruding the tubular shaped article.

Abstract: A method and apparatus for trimming molded hollow plastic articles having flash and a finish for a closure. Articles are moved in succession through the load, deflashing, facing, inspection, rejection and unload stations of a trimming apparatus by vacuum heads. The articles are picked up by vacuum heads and transferred through the stations by intermittent rotation of a turret carrying the vacuum heads. To ensure proper location, each article is picked up in the load station by a vacuum head and continuously engaged by this vacuum head throughout the deflashing, facing and inspection stations and into the unloading station unless rejected and released in the rejection station.To facilitate loading, unloading and operations in the work stations on the articles, their orientation can be changed from one station to another. To enable variation of the cycle time of the apparatus, the turret and the operating mechanism in the various stations is driven by a common variable speed drive.

Such containers show high resistance to shrinkage and gross deformation in shape upon exposure to high temperatures.

Abstract: A polyester or copolyester container is made with a heat activated high barrier copolyester label applied to the container sidewall. The process for producing the high barrier container that is a hollow polyester or copolyester body with a barrier label effectively applied to its outer sidewall, includes forming the container by an extrusion blow method, injection blow method, orientation-blow method, or orientation blow-heat set method and applying the barrier label via an "in-mold" technique utilizing a heat-activatable high barrier copolyester resin as the adhesive.

Abstract: A plastic bottle delabeling apparatus in which a series of heated rolls that are driven at increasingly greater peripheral velocity engage the plastic bottles to flatten and stretch the bottles. While flattening the bottles, the apparatus heats the plastic bottle surface by the contact with the heated rolls, effectively softening the bond of any label to the bottle. The flattened bottle is then passed through a pair of opposed rotating brush rolls which strip the loosened label from the bottle. The rolls are in vertically opposed sets with the peripheral velocity of the sets of rolls being successively greater in the direction of movement of the bottles therebetween.

Abstract: Disclosed is a process of making an oriented and heat set thermoformed hollow article of poly(ethylene terephthalate) so that the sidewalls of the articles resulting from the process have a density over 1.391 cc./gm. and an onset-of-shrinkage temperature over 105.degree. C. In the process, a sheet preheated to a temperature suitable for orientation is biaxially stretch thermoformed and then while the hollow article walls are still in contact with the mold walls, the article is raised to a higher heat setting temperature in the range of about 220-250.degree. C. thus heat setting the article, and while the article is still under restraint resisting shrinkage, quenching the sidewalls of the article to a temperature that will provide a shrinkage of less than about 5% by volume and the above onset-of-shrinkage temperature of at least about 105.degree. C.
