Abstract
A device for automatically securing a borderwire on a mattress innerspring comprising a plurality of coils is disclosed. The device comprises a tool for sequentially joining segments of the borderwire to perimeter ones of the coils located along a perimeter of the innerspring, apparatus for advancing the mattress innerspring and borderwire toward the tool, a conductive element for sequentially contacting the perimeter ones of the coils, a sensor for detecting contact of the conductive element with the perimeter ones of the coils, and a control responsive to the sensor for actuating the tool.
Claims8
A device for automatically securing a borderwire on a mattress innerspring, said mattress innerspring comprising a plurality of coils including perimeter coils located along a perimeter of said innerspring the device comprising:
- a tool for sequentially joining segments of said borderwire to said perimeter coils;
- means for advancing said mattress innerspring and borderwire toward said tool;
- an element for sequentially contacting each of said perimeter coils;
- a sensor for detecting contact of said element with said perimeter coils;
- and
- means responsive to said detection for actuating said tool.
A device for automatically securing a borderwire on a mattress innerspring, said mattress innerspring comprising a plurality of coil including perimeter coils located along a perimeter of said innerspring, the device comprising:
- a surface;
- a clip wrapping tool for sequentially joining segments of said borderwire to said perimeter coils;
- means for advancing said mattress innerspring and borderwire along said surface;
- a lever arm pivotally joined below said surface and having a first end and a second end;
- a sensor extending upwardly from said first end of said lever arm for detecting when each of said perimeter coils is located a distance from said tool, said sensor including a contact rod, and means for detecting sequential contact of said contact rod with and each of said perimeter;
- and
- means responsive to said sequential detecting means for sequentially actuating said tool.
