  • Patent number: 7905693
    Abstract: A method and apparatus for loading tube bundles on a railcar includes placing the tube bundles lengthwise on the car and stacked above the car to form packs. These packs are spaced longitudinally one from another on the car. Spacing bags are placed within the longitudinally extending spaces. Plates are displaced one from another by the spacing bags to push against the ends of the packs.

  • Patent number: 7540124
    Abstract: An apparatus and method for wrapping a plurality of tubes which includes a plurality of supporting stations, each of which includes a pair of stanchions upon which pulleys are positioned. An endless belt is threaded along the pulleys and one of the pulleys is driven by a drive motor to move the endless belt to rotate a bundle of tubes positioned on the belt. A roll of stretch wrapping plastic material such as polyethylene is disposed upon a trolley movable along a rail. The polyethylene plastic film engages the exterior of the bundle of tubes and as the bundle rotates, the film is moved from the roll to encompass and wrap the bundle of tubes.

  • Patent number: 7458755
    Abstract: A method for loading tube bundles on a railcar includes placing the tube bundles lengthwise on the car and stacked above the bed of the car to form tube bundle packs. The packs are separated by panels. A spacing block is configured to go within the longitudinally extending remaining space left over after loading a finite number of packs. This spacing block include parallel plates which are rigidly displaced one from another by blocks. Padding is arranged on the outer side of the plates and the panels. Padding is arranged on the bulkheads as well. The panels and spacing block may be tied to the railcar through boards and dunnage.

  • Patent number: 7381021
    Abstract: A method for loading tube bundles on a railcar includes placing the tube bundles lengthwise on the car and stacked above the car to form packs. These packs are spaced longitudinally one from another on the car. Spacing blocks are configured to go within the longitudinally extending spaces. These spacing blocks include parallel plates which are rigidly displaced one from another by blocks. Padding is arranged on the outer side of the plates. One set of blocks extending between the parallel plates is arranged in juxtaposition with the bed of the railcar to receive strapping for retention.

  • Patent number: 6598287
    Abstract: A method and apparatus for sizing a galvanized tube, in which two sizing stations are used. A first sizing station having at least one sizing roll is used for sizing the tube prior to the galvanizing process. A second sizing station is then used, the station having at least one resilient sizing roll which is used for sizing the tube after the galvanizing process. By using a first sizing stand, which does most of the sizing work, the rolls in the second sizing stand need not pull the galvanized tubes with as much force. The advantage of the present invention is that cooler temperatures, faster mill speeds, and less cosmetic flaws in the finished galvanized product are seen, due to the lower force applied by the second sizing stand rolls to the galvanized product.
