A machine for cutting an elongated layup of sheet material has a conveyor table for supporting the material and advancing it while it is being cut. A carriage assembly moves a cutting tool in cutting engagement with the material on the conveyor table in response to signals from a programmable controller. The conveyor table and carriage assembly are connected in one system so that the programmed movements of the cutter are relative to the movement of the conveyor thereby enabling the material to be cut in accordance with a predetermined program while simultaneously advanced by the conveyor table. Another cutting machine which has a rotary drum conveyor for supporting and advancing sheet material has a movable tool carriage coupled to the drum conveyor for movement relative to the conveyor by a ring gear and pinion.
In an apparatus for working on sheet material and having conveying means for supporting and moving sheet material, a carriage assembly, means supporting the carriage assembly for movement relative to the conveyor means and in one and an opposite direction generally parallel to the direction of movement of the conveyor means, instrument means mounted on said carriage assembly for movement with the carriage assembly and in working relation to sheet material supported by the conveyor means, and drive means for moving the carriage assembly relative to the conveyor means to move the instrument in working relation to the sheet material supported by the conveyor means, the improvement wherein said drive means comprises coengaging drive elements including one drive element mounted on the conveyor means to move with the conveyor means and another drive element supported on the carriage assembly to move with the carriage assembly and relative to the conveyor means.
In an apparatus for cutting sheet material and having an endless conveyor, a sheet material supporting surface defined by the conveyor, vacuum means for releasably securing sheet material on the supporting surface, a carriage assembly, means supporting the carriage assembly for movement in one and an opposite direction parallel to the direction of movement of the conveyor, a cutter assembly supported on the carriage assembly and including a reciprocating blade, a drive means for moving the carriage assembly in the one and the opposite direction and relative to the material supporting surface to move the blade in cutting engagement with sheet material supported on the supporting surface, the improvement wherein said drive means comprises coengaging drive elements including gear means carried by and movable with said conveyor, a pinion carried by said carriage assembly to move with said carriage assembly and relative to said conveyor and engaged with said gear means, and a drive motor for rotating said pinion in driving engagement relative to said gear means.
