Abstract
Abstract A method and apparatus are provided for forming large wall or shell-like structures such as tanks, vessels, containers and buildings on the site where they are to be used. In a first form, a filament-winding technique involves the use of a preform erected at the location of the shape to be formed, the preform and/or the filament-winding equipment being rotatable so as to dispose a plurality of filaments on the receiving surface in a circular arrangement to define strata of the wall being formed. The preform may comprise a thin sheetlike member erected at the site of use. The sheetlike wall may be self-supporting, supported by a skeletal frame or inflated and supported by air pressure. The filament-winding apparatus may include a base for supporting the preform and the eventual housing to be formed thereof, said base being stationary such as a tarmac formed on the ground or rotatable on a tarmac to rotate the preform while the apparatus for directing material such as fluent material and/or filaments against the surface of the preform moves in a vertical direction to properly dispense same and buildup a suitable wall formation thereof. In another form, the dispensing apparatus is also operative to rotate about the preform on a track or on an overhead conveyor such as a boom or overhead track erected at the site of location of the vessel or shell.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
29 words
Apparatus in accordance with claim 1, said die comprising a sheeting die operative to form said hardenable material into a sheet which is layed on and covers said preform.
Claim 2
Dependent Claim
46 words
Apparatus in accordance with claim 1, said die being shaped to form an oblong structural member, said manipulation means being operative to lay said oblong member against said preform, and a means for securing said oblong member to said preform as it exits from said die.
Claim 3
Dependent Claim
35 words
Apparatus in accordance with claim 1, said die being shaped to form a plurality of oblong structural members thereof, said manipulation means being operative to lay said plurality of oblong structural members onto said preform.
Claim 4
Dependent Claim
40 words
Apparatus in accordance with claim 1, said extrusion means including means for extruding and feeding a plurality of winding filaments from said head and means for controlling rotation of said preform means to permit said filaments to be wound thereon.
Claim 5
Dependent Claim
203 words
Apparatus for forming large hollow bodies comprising: a. a preform having a wall against the outer surface of which layup material may be deposited, b. a track fixedly supported around said preform at the lower end thereof, c. a carriage operative to travel said track, d. a guideway supported at its lower end by said carriage, and extending upwardly therefrom adjacent said preform, e. layup means for material to be disposed against the outer surface of said preform including a working head and means for dispensing material therefrom, f. means for movably supporting and moving said head along said upwardly extending guideway, g. first power operated means for driving said head in both directions on said guideway, h. an upstanding support supported and extending beyond the upper end of said preform and inwardly of the wall of the preform, i. said upstanding support being connected to the upper end of said vertical guideway for supporting said guideway from above, j. second power operated means for driving said carriage around said track to convey said working head around and adjacent to said preform, k. means for feeding material to be deposited to said working head and control means for said material feeding means, and
Claim 6
Dependent Claim
218 words
Apparatus for forming large hollow bodies comprising: a. a preform having a wall against the surface of which layup material may be placed and solidified in situ thereon, b. a manipulator including an upstanding support supported interior of said preform, c. a first arm pivotally supported by said upstanding support, and d. a layup fixture supported at the end of said first arm, e. a working head supported by said layup fixture beyond the outer surface of said preform, f. means for operating said layup fixture to move said working head vertically a distance away from the outer surface of the preform, g. means for feeding material to be deposited on said preform to said working head, and control means for said material feeding means, h. first means for rotating said first arm about said upstanding support to convey said layup fixture around said preform, first control means for said rotating means, i. second control means for said means moving said working head vertically and j. master control means for controlling the operation of said first and second control means and said control means for said means for feeding material to said working head in a preprogrammed cycle whereby said working head is predeterminately conveyed about said preform and said material is predeterminately dispensed therefrom onto said preform.
Claim 7
Dependent Claim
88 words
An apparatus in accordance with claim 7, wherein said layup fixture includes a second arm pivotally supported at the end of the first arm, a third arm pivotally supported at the end of said second arm ands supporting said working head, and means controlled by said master control means for power rotating said second arm on said first arm and said third arm on said second arm to permit predetermined positioning of said working head with respect to the surface of said preform at different height locations thereof.
Claim 8
Dependent Claim
233 words
Apparatus for forming large hollow bodies comprising: a. a preform defining a surface of revolution, b. means for supporting said preform in a substantially vertical attitude, c. a circular track fixedly supported at the lower end of said preform, d. a carriage operative to travel said track, e. a vertical guideway supported by said carriage and operative to travel around said preform as the carriage travels said track in a path whereby said vertical guideway is guided at substantially a constant distance away from the surface of revolution of said preform, f. layup means for material to be disposed against the outer surface of said preform including a working head and means for dispensing material therefrom, g. means for movably supporting and moving said head along said vertical guideway, h. first power operated means for driving said head in both directions on said vertical guideway, i. second power operated means for driving said carriage around said track to convey said working head around and adjacent to the working surface of said preform, j. means for feeding material to be deposited to said working head, and k. control means for controlling operation on said first and second power means and said means feeding material to said working head to cause the head to predeterminately travel said vertical guideway and to be conveyed around said preform so as to predeterminately dispose material against said preform.
Claim 9
Independent Claim
119 words
An apparatus for forming hollow bodies by predeterminately disposing material onto a preform comprising: layup means including a working head, means for supporting said preform adjacent said working head and means for relatively moving said head and said preform to cause the head to predeterminately scan the surface of said preform, means for controllably feeding radiation curable material to said working head, and feeding said material from said head to said preform as the head scans the surface of the preform, and a source of radiation disposed adjacent to said working head and operative to direct radiation against said radiation curable material as it is disposed against said preform so as to cure same in situ on said preform.
Claim 10
Dependent Claim
39 words
