Patent number: 4052152Abstract: Cylindrical two-piece cans are decorated with thermally curable inks and coatings and are placed on generally horizontally extending pins of a pin-chain conveyor. The cans are then moved through a flame drying chamber to dry the inks and coatings by direct impingement of flame on the can surface. The cans are thereafter moved through a cooling chamber and then are discharged from the pin-chain conveyor which circulates back to the decorator unit to receive newly decorated cans. The pins of the pin-chain conveyor can be at an angle to the horizontal and the pins can have brushes or the like to grip the internal surface of the can. The flame dryer unit consists of gas and air-fed burner heads disposed in one of several different patterns along the path taken by the cans through the flame dryer housing. Flame impinges directly on the can and the can moves through the tunnel at a speed sufficient to prevent heat damage to the can.Type: GrantFiled: February 18, 1976Date of Patent: October 4, 1977Assignee: Sun Chemical CorporationInventors: Edward J.

Patent number: 4012271Abstract: There is disclosed a water cooled support bar comprised of a pipe within a pipe which assures the axial position of a cylinder-like sleeve of heat shrinkable foam thermoplastic material on a glass container during transport from an assembly station on a turret machine into a tunnel-type oven and until the thermoplastic sleeve shrinks sufficiently snugly onto the container to be held thereby. Polyethylene material, and perhaps other polyolefins, have the tendency to become more pliable and grow or enlarge under heat prior to actually shrinking. It is during this initial heat-up time the invention serves to retain the sleeve form in place on the container. The support pipe includes a Teflon or like lubricious surface layer at least along the side thereof adjacent the plastic sleeve lower edge. The lubricious surface layer combined with water cooling prevents sticking of the plastic on the support bar.Type: GrantFiled: February 17, 1976Date of Patent: March 15, 1977Assignee: Owens-Illinois, Inc.Inventors: Marshall G. Brummett, Russell W. Heckman, George A. Nickey, James E. Taylor

Patent number: 4009298Abstract: In the coating of glass containers with a plastic film, the curing of the applied plastic film to the container is an extremely important phase of the overall process. Generally, the most economical method of achieving cure is to carry a plurality of the bottles through an oven where the curing operation is accomplished, the bottles being carried on a moving belt. In order to allow such containers to be carried on the moving belt, the base must achieve a partial cure, prior to being placed on the conveying means for passage through the oven. In accordance with the present invention, means and a method are disclosed for providing a sufficient cure of the coated container base to allow for final curing in the oven.Type: GrantFiled: March 6, 1975Date of Patent: February 22, 1977Assignee: Midland Glass Company, Inc.Inventor: Joseph C.

Patent number: 3977091Abstract: A device for tempering and/or sterilizing objects which must be kept free of contamination by foreign particles, such as for example, ampules sterilized in pharmaceutical preparations, has a housing and means for supporting the objects in the housing. A pair of gas distribution plates are mounted in the housing in spaced relationship to each other, on either side of the support means, and cooperate with means for supplying conditioned air to produce a laminar flow of the conditioned air downwardly over the objects being treated. The conditioned air has a substantially different temperature than the objects being treated and can be either heated or cooled depending upon whether the device is used for sterilizing or tempering. Because of the maintenance of laminar flow in the housing, the number of contaminating particles per space unit which can come into contact with the objects being treated is decreased.Type: GrantFiled: May 24, 1972Date of Patent: August 31, 1976Assignee: Hoechst AktiengesellschaftInventors: Hans-Peter Hortig, Hans Pfeiffer
