Claim:
1. A CNC machine operable in producing an article of a selected configuration, comprising: a worktable supported on a bed, having a support surface disposed in an x-y plane, disposed in one of a fixed condition on said bed and a displaceable condition along a y-axis; a gantry supported on said bed along an x-axis, disposed in one of a fixed condition on said bed with said worktable displaceable along the y-axis and a displaceable condition along the y-axis on said bed with said worktable disposed in a fixed condition on said bed; a carriage mounted on said gantry, displaceable along an x-axis; a tool carrier mounted on said carriage, displaceable along a z-axis, provided with an extruder for forming a thermoplastic material extrudable through an outlet conduit; a tool holder mounted on said tool carrier, rotatably displaceable about a z-axis; a tool support shaft provided with an axis disposed in an x-y plane, journaled in said tool holder and rotatably displaceable about the axis thereof; a dispenser conduit mounted on said tool support shaft, disposed perpendicularly relative to the axis thereof accommodating an applicator at an outlet end thereof; an extruding mechanism mounted on said dispenser conduit configured to extrude through an outlet thereof a bead of said thermoplastic material; and a flexible hose provided with a first end supported on said tool carrier, forming a rotary union with said outlet conduit of said extruder, and a second end communicating with and attached to an inlet end of said dispenser conduit, wherein said first end of said flexible hose extends through an opening in a carrier bottom wall disposed along said z-axis, is connected to a swivel supported on said carrier bottom wall and rotatable about said z-axis, and connected to said outlet conduit of said extruder via a rotary union disposed along said z-axis; and said second end of said flexible hose includes said dispenser conduit journaled in a bearing disposed in a support conduit mounted on said tool support shaft perpendicularly relative to the axis thereof; and a first servomotor for selectively rotatably displacing said swivel member, imparting a rotational displacement of said first end of said flexible hose within said rotary union with said outlet conduit of said extruder and corresponding rotational displacement of said dispenser conduit disposed on said second end of said flexible hose, journaled in said bearing disposed in said support conduit mounted on said tool support shaft.
