locating a wood frame on the base, the wood frame including a plurality of spaced apart, generally parallel frame sections; locating a plurality of modules arranged in a plurality of rows on the frame, each row including a plurality of modules formed from a continuous metal wire with each module having a top portion spaced apart from the frame, first and second side portions extending downwardly from the top portion, and a bottom portion connecting the first and second side portions, the bottom portion being positioned on one of the frame sections and the first and second side portions of the module being spaced apart to define an open access area above the bottom portion; locating a fastening tool above the base; providing a module alignment device; moving the module with the module alignment device; moving the fastening tool without the use of a vision guidance system in a direction generally perpendicular relative to the base and through the open access area of a module until the fastening tool is located at a target fastening location; and securing the bottom portion of the module to the frame at the target fastening location with the fastening tool. ### Claim 2 (depends on 1) The method of claim 1, wherein the module alignment device is located on the fastening tool so that the two moving steps are performed simultaneously. ### Claim 3 (depends on 1) The method of claim 1, wherein engagement of the module alignment device with the module during the step of moving the module with the module alignment device causes relative movement between the module and the wood frame. ### Claim 4 (depends on 1) The method of claim 1, wherein the module alignment device is an alignment tool separate from the fastening tool, the alignment tool being movable to position the modules relative to the frame. ### Claim 5 (depends on 4) The method of claim 4, wherein the alignment tool is located below the base. ### Claim 6 (depends on 1) The method of claim 1, wherein the fastening tool is one of a stapler, a nailer, and a glue dispenser. ### Claim 7 (depends on 1) The method of claim 1, wherein the step of moving the module with the module alignment device occurs if the module is misaligned relative to at least one of the frame and the fastening tool. ### Claim 8 A method of forming a portion of a box spring or mattress foundation, the method comprising: providing a base; locating a wood frame on the base, the wood frame including a plurality of frame sections; locating a plurality of spring modules above the frame, each module having a bottom portion positioned on one of the frame sections; locating a fastening tool above the base, the fastening tool being initially spaced apart from the plurality of spring modules and the frame; providing a module alignment device; moving the module with the module alignment device to compensate for misalignment of the module relative to at least one of the frame section and the fastening tool; moving the fastening tool relative to the base, the plurality of spring modules and the frame without the use of a vision guidance system until the fastening tool is located at a target fastening location; and securing the bottom portion of the module to the frame at the target fastening location with the fastening tool. ### Claim 9 (depends on 8) The method of claim 8, wherein the module alignment device is located on the fastening tool so that the two moving steps are performed simultaneously. ### Claim 10 (depends on 8) The method of claim 8, wherein the module alignment device is an alignment tool separate from the fastening tool, the alignment tool being movable to position the modules relative to the frame. ### Claim 11 (depends on 8) The method of claim 8, wherein the fastening tool is one of a stapler, a nailer, and a glue dispenser. ### Claim 12 (depends on 8) The method of claim 8, wherein the step of locating a plurality of spring modules above the frame includes locating a plurality of modules arranged in a plurality of rows on the frame, each row including a plurality of modules formed from a continuous metal wire with each module having a top portion spaced apart from the frame, first and second side portions extending downwardly from the top portion, and a bottom portion connecting the first and second side portions, the first and second side portions of the module being spaced apart to define an open access area above the bottom portion. ### Claim 13 An apparatus for securing a plurality of modules to a frame to form a portion of a box spring or mattress foundation, each module including first and second side portions and a bottom portion coupled to the first and second side portions, the bottom portion being located on the frame, the first and second side portions of the module being spaced apart to define an open access area above the bottom portion, the apparatus comprising: a base configured to support the frame and the plurality of modules; a fastening tool located above the base and initially spaced apart from the plurality of modules and the frame, the fastening tool being configured to secure the bottom portion of a module to the frame; a module alignment device configured to engage the module to move the module to compensate for misalignment of the module relative to at least one of the frame section and the fastening tool; and a drive mechanism configured to move the fastening tool relative to the base, the plurality of spring modules and the frame in a direction generally perpendicular to the base without the use of a vision guidance system, the fastening tool moving through the open access area of a module to a target fastening location to permit the fastening tool to secure the bottom portion of the module to the frame at the target fastening location. ### Claim 14 (depends on 13) The apparatus of claim 13, wherein the module alignment device is a mechanical guide configured to engage the module as the mechanical guide moves relative to the module, engagement of the mechanical guide with the module causing relative movement between the fastening tool and the module so that the fastening tool and the module are aligned at a target fastening location to permit the fastening tool to secure the bottom portion of the module to the frame at the target fastening location. ### Claim 15 (depends on 14) The apparatus of claim 14, wherein the mechanical guide is located on the fastening tool. ### Claim 16 (depends on 13) The apparatus of claim 13, wherein the module alignment device is an alignment tool separate from the fastening tool, the alignment tool being movable to position the modules relative to the frame. ### Claim 17 (depends on 16) The apparatus of claim 16, wherein the alignment tool is located below the base. ### Claim 18 (depends on 13) The apparatus of claim 13, further comprising a controller configured to guide movement of the fastening tool relative to the base, the frame and modules located on the base. ### Claim 19 (depends on 18) The apparatus of claim 18, wherein the controller includes a memory for storing a plurality of standard positions for each of the modules on the frame and means for guiding the fastening tool to the plurality of stored standard positions. ### Claim 20 (depends on 18) The apparatus of claim 18, further comprising a magnetic sensor configured to locate the module, the magnetic sensor providing a control signal used by the controller to position the fastening tool relative to a module. ### Claim 21 (depends on 13) The apparatus of claim 13, wherein the fastening tool is pivotably coupled to a support. ### Claim 22 (depends on 13) The apparatus of claim 13, wherein the fastening tool is one of a stapler, a nailer, and a glue dispenser.
