Abstract:
An apparatus for applying sealant to a side seam in a container sidewall formed by overlapping portions of the sidewall is provided. The apparatus includes conveying means operable for moving a container into and away from a sealing station. Sensing means is located adjacent the conveying means and is operable for sensing the rotational position of a container sidewall. Drive means is operable for selectively rotating a container to a predetermined rotational position. A sealant dispensing means is positioned adjacent the conveying means at the sealing station and is operable for dispensing sealant onto the seam along substantially the entire length of the seam by a movement of the dispensing means relative to the container. A second sealant dispensing means and station can be provided adjacent the conveying means for applying sealant to a seam between a bottom member and the sidewall of the container.
Abstract:
This relates to a powder applicator for applying a coating stripe in powder form to inside seams of can bodies. The powder applicator is particularly adapted to be utilized in conjunction with welding apparatus for welding the side seams of can bodies and wherein the diameters of the can bodies are too small to permit the provision of the customary excess powder return duct. The powder applicator is located at the 12:00 o'clock position and thus the excess powder will not merely fall out of the applicator. Accordingly, there is provided a channel defined by a porous block having air or gas circulated therethrough and wherein the terminal end of the channel is closed by a deflector block which will deflect any excess powder out of the applicator into an overlying hood which is primarily intended to take away powder overspray which normally occurs between adjacent, but spaced, can bodies.
Abstract:
A pipe interior surface coating device having a spray apparatus for distributing a coating material around an axis of rotation. A carriage supports the spray apparatus and is adapted to be moved longitudinally inside a pipe. A bracket may be used to position the spray apparatus at a chosen distance away from one end of the carriage and the carriage may include apparatus to position the axis of rotation of the spray means concentrically within the pipe.
Abstract:
A container wherein exposed surfaces thereof which are particularly subjected to a chemical reaction, such as corrosion, are protected by the application of a thixotropic lacquer. A typical installation is the application of a band of thixotropic lacquer internally of the container along the longitudinal side seam. A thixotropic lacquer has the characteristic that there is very little flow after its application to a surface, and thus is particularly adapted for covering raw edges and like exposed areas of containers. The thixotropic lacquer is applied preferably in plural closely adjacent streams which unite after the lacquer engages the container surface. Beneficial results are obtained by adjusting the temperature of the container and/or lacquer, and further by heating the applied band of lacquer.
Abstract:
A steel pipe with a thermoplastic cover has the coverage of a welding seam reinforced by hot air heating the cover along the plastic and extruding a strip of similar plastic thereon, followed by cold water spray cooling. The pipe is centered as to the position of the welding seam vis-a-vis the heating and extruding equipment during relative longitudinal movement.
Abstract:
An inner burr cutting, inner face cleaning and inner face painting apparatus for long pressure-welded pipes of medium and small diameters comprises a carriage mounted on a base for reciprocal movement, a supporting tube mounted on the carriage to be inserted into a long pressure-welded pipe of a small or medium diameter, a hollow rotary shaft projecting from the supporting tube, an inner burr cutting device fixed to the rotary shaft, a mechanism for centering the inner burr cutting device in the pressure-welded pipe, a spatter crushing brush, an electromagnet device for attracting spatters and inner burr chips, a spattering prevention device, a paint spraying device disposed ahead of the electromagnet device, and a cooling device surrounding the pressure-welded pipe. After the inner and outer burrs have been removed, the cooling device, spatter crushing device, electromagnet device and paint spraying device are used to clean the inner face of the pressure-welded pipe and paint the portions of the inner face of the pressure-welded pipe from which the inner burrs are removed and which are burnt.
Abstract:
A powder system for electrostatically applying a powder coating to a can body side seam area. The system incorporates a catcher which is positioned and is of a configuration to catch and return substantially all of the powder overspray and stray powder particles. A constant vacuum is maintained in the catcher by way of a vacuum flow transducer.
Abstract:
A fluid delivery system is disclosed utilizing a high pressure cleaning fluid, such as a blast of high pressure water, to remove material from the inside wall of the stator of a relatively large electric motor. In the preferred embodiment of this invention illustrated, the fluid delivery system includes a nozzle carriage having a high pressure nozzle movable along the length of the inside wall of the stator to be cleaned, a rotating carriage frame for rotating the nozzle about the inside wall of the stator to be cleaned, a vertically movable wall upon which the rotating carriage frame is mounted, and a base frame or skid on which the vertically moving wall is mounted. The nozzle can be positioned to move along a desired longitudinal path along the inside of the stator, such as along longitudinal grooves where the material to be removed is located.
Abstract:
Method and apparatus for applying wax to a cardboard box blank formed from board having substantially straight parallel open-ended internal interstices, in which a zone of cascading flow of wax impregnated material is generated and the box blank is passed through the zone with the board interstices open to the wax flow.
Abstract:
Methods and apparatus are disclosed for directing a fluid spray against the interior surfaces of a reaction vessel, without the need for operating personnel to enter the vessel, employing orbiting nozzles connected by a conduit to an annular piston assembly all of which are contained in a cylinder housing mounted externally on the vessel. A hydraulic or pneumatic force is alternately applied to one of the piston surfaces, the rate and direction of movement of the piston, and hence the spray nozzles being controlled by the discharge of fluid from the cylinder housing on the opposite side of the piston. In one embodiment the hydraulic pressure used to drive the piston is provided by the same pressurized fluid which is used in the spraying operation.
