As for assembly line workers being "too lazy" to throw out the broadcast sheet....Would it not take more effort to put the complete thing behind the seat springs? If it was put there during the sub assembly, and it can't be seen after final assembly then why would it be deemed necessary to remove them and discard them?
The assembly shop doing seat upholstery had no more than 2 minutes assy time per seat to scan the Bsheet, pull the appropriate frame, foam and upholstery into shape and hog ring it together, so rather than stand in a pile of discarded BSheets during the day, the worker threw the BS on the springs, placed the foam over it along with upholstery, hogged it, then racked it for delivery to the line,....the BS was basicaly hidden trash at that point, not the "Holy Grail" it has become
