Abstract: The invention provides that a flexible liner is everted into a passageway to line same using liquid under pressure. The liner is fed through an enclosure before it everts and eversion is achieved by pressurization of the liquid in the enclosure. The feed of the liner through the enclosure is preferably controlled by the drivable feed rollers through a nip of which the liner passes. The rollers preferably have projections which engage the liner positively to engage the liner. The invention has particular applicability to the placement of liners which although flexible and evertible when being installed, set hard when in position lining the passageway.

Abstract: Insulated sheathing, such as a covering for a bundle of flexible tubes which deliver chilled beverages to a dispensing head, may be covered on their outer side by a seamless flexible sheath and similarly on the inner side of the insulation which surrounds the bundle of tubes. Flexible sheathing for the inner sheath is loaded bunched together on the outer surface of a hollow core near its downstream end.

Abstract: An apparatus and method for placing component parts on the ends of flexible tubing which is employed in an I.V. administration set. Flexible tubing is continuously supplied in a rectilinear manner and cut into predetermined lengths. These lengths have the ends thereof moved in a substantially transverse manner with respect to the original direction. Each end is then placed in a solvent-type solution and subsequently into a cavity of a component part. All of the foregoing functions are accomplished continuously and automatically in a device which employs a conveyor system for the cut tubing and a separate conveyor system for the component parts. The conveyors travel over a substantial elliptical pathway and along a horizontal axis. The upper conveyor is positioned with respect to the lower conveyor such that their pathways overlap a substantial distance. The upper conveyor provides a multiplicity of carrier members to which are fed and positioned predetermined cut lengths of flexible tubing.

Abstract: To fill up the ring-shaped gaps between the tubes and fins of a tube and fin type heat exchanger with a corrosion protective hardenable filler, a unit made up of two closing pieces with filler material between them is pushed by means of the tube to be inserted in the stacked fins through the space formed by the collars of the openings in the fins which are stacked together for assembly into a heat exchanger. On passing this unit through the stacked fins the ring-shaped gaps are filled up with the filler material. The remaining thin film on the collars is also forced into the ring-shaped gaps when the tubes are subsequently expanded.A device for carrying out the process comprises a sleeve with a mandrel which slides inside the sleeve and forms a seal with the sleeve and a piston which likewise slides in the sleeve and forms a seal therewith and which lies ahead of the mandrel forming a space which can be varied in size and which accommodates the filler material.

Abstract: An apparatus for forming a smooth, even, substantially encapsulating layer of a heat shrinkable polyolefin plastic on a glass container. The body of the container is substantially greater in diameter compared with the neck. A cylindrical sleeve of polyolefin is telescopically placed along the outer surface of the container and the two are conveyed together into a heating oven for shrinking the sleeve snugly over the container. During heating, the polyolefin initially softens and becomes limp such that the sleeve tends to fold over or upon shrinking creates wavy top margins on the shrunken covering. The apparatus provides controlled rotation of the bottle and sleeve in the oven to apply a centrifugal force to the limp plastic which remains erect and billowed outwardly to give the material time to react with the heat such that the sleeve material shrinks into overall even, snug contact about the contour of the container without folds and wrinkles.

Each diffuser housing is provided with a longitudinally extending slot presenting directional discontinuity at its two end portions. The two end portions of each slot may be horizontal, while the control portion of each slot is sloped in a vertical direction and extends from one end portion of the slot to the other. Provision is made to feed hot air through the slots into a tunnel so as to contact the films on the containers or objects moved by the conveyor.

Abstract: The invention disclosed sets forth a machine for forming a sleeve of a shrinkable, cellular polymeric material from a predecorated web. The web is processed to provide (1) a partial-depth slit along the longitudinal dimension, and (2) cross-dimension pleats. Predecorated shrunken neck labels are formed from the web for overlying the neck and closure of the bottle and including a pilfer-proof feature. Such a label is formed from the processed web by cutting a blank having the cross pleats therein and winding the blank on a mandrel to overlap the ends and seam the overlap to make a sleeve. The sleeve is stripped onto the top neck end and over the closure of a bottle at room temperature to a label position and shrunken to a snug fit, the pleats absorbing wrinkles that occur in shrinking the material onto a "cold" bottle.The disclosure includes a novel machine for making the sleeve from a plastic web and placing it on the bottle.

Abstract: 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.
