Abstract A flexible track of modular construction for mounting a tool holding carriage on to a structure or workpiece. The track is preferably fabricated from a flexible plastic material such as a fiber-resin composition to permit its being contoured into conformity with the particular configuration of the structure upon which it is to be mounted for purposes of conducting welding or machining operations. Vacuum cavities in the track base provide holding means for securing the track to the structure by application of vacuum pressure. The carriage is mounted on the flexible track by engagement of its rollers with rails extending laterally from the track base. A rack gear extending along the length of the track module is engaged by the drive gear of the carriage whereby movement of the carriage along the track is achieved and maintained under positive control.
A track for supporting a tool holding carriage onto a workpiece comprising: a base having front, back and side surfaces, rail means having front, back and side surfaces, said rail means projecting laterally from said side surfaces of said base, said base having a vacuum chamber integral therewith for securing said track onto a workpiece, passageways in said base in communication with said vacuum chamber for connection with an evacuation means, and said track being of flexible material whereby said track may be configured to conform to the configuration of said workpiece.
