Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
174 words
For use with a facility to manufacture laminar structures a gantry means to traverse a path to be taken in such manufacture, said gantry being comprised of: a frame having ends with side legs with columns connecting said ends to space said ends from one another, said side legs having drive means to provide for movement of said frame; a platform movably mounted to and between said ends, said platform being movable between the ends and within the side legs from one side to the other side of said frame; means to mount a composite tape laying a sizing device on said platform to be movable with and relative to said platform, said composite tape laying and sizing device including a rotatable support from said platform for a housing having a tape feeding roll for a tape with a separator backup, a tape laydown means and a separator take-up reel; and means operatively arranged in at least some of said side legs to operate said drive means to give controllable motion to said gantry.
Claim 2
Dependent Claim
174 words
For use with a facility to manufacture laminar structures a gantry means to traverse a path to be taken in such manufacture, said gantry being comprised of: a frame having ends with side legs with columns connecting said ends to space said ends from one another, said side legs having drive means to provide for movement of said frame; a platform movably mounted to and between said ends, said platform being movable between the ends and within the side legs from one side to the other side of said frame; means to mount a composite tape laying a sizing device on said platform to be movable with and relative to said platform, said composite tape laying and sizing device including a rotatable support from said platform for a housing having a tape feeding roll for a tape with a separator backup, a tape laydown means and a separator take-up reel; and means operatively arranged in at least some of said side legs to operate said drive means to give controllable motion to said gantry.
Claim 3
Dependent Claim
147 words
For use with a facility to manufacture laminar structures a gantry means to traverse a path to be taken in such manufacture, said gantry being comprised of: a frame having ends with side legs with columns connecting said ends to space said ends from one another, said side legs having drive means to provide for movement of said frame; a platform movably mounted to and between said ends, said platform being movable between the ends and within the side legs from one side to the other side of said frame; means to mount a laser operatively associated by means to the platform to provide a cutting laser beam movable with and within the gantry to cut a desired pattern of the laminar structure; and means operatively arranged in at least some of said side legs to operate said drive means to give controllable motion to said gantry.
Claim 4
Dependent Claim
147 words
For use with a facility to manufacture laminar structures a gantry means to traverse a path to be taken in such manufacture, said gantry being comprised of: a frame having ends with side legs with columns connecting said ends to space said ends from one another, said side legs having drive means to provide for movement of said frame; a platform movably mounted to and between said ends, said platform being movable between the ends and within the side legs from one side to the other side of said frame; means to mount a laser operatively associated by means to the platform to provide a cutting laser beam movable with and within the gantry to cut a desired pattern of the laminar structure; and means operatively arranged in at least some of said side legs to operate said drive means to give controllable motion to said gantry.
Claim 5
Dependent Claim
47 words
The apparatus of claim 2 wherein the laser is fixed to the platform and a system of mirrors is used to provide the laser cutting beam to a movable head directing said cutting beam downwardly, said moveable head being slideable along rod means supported by said platform.
