was adapting the FOOT thats the thing that holds the fabric down a zipper foot is very narrow 1/8″ wide
you sew down the left side and up the right side ..an 18 inch zipper sewer could do 80 doz a day…the zipper was the second thing done ..before it was assembled (NOT the LAST) thing done…most home workers try to do it last ,that makes it almost impossible to do right,and fast….
The key was to add the small parts first before the Garment got too big to handle set the pockets first,even button holes were done first thing then as the Garment got assembled it got slower to handle.Buttons were done last .Lots of prep like hemming sleeves and putting elastic on sleeves,making collars were done before anything was assembled .The preparation before assembly was key to speed. .
It was my job to plan how it was assembled ,and who did what and train everyone …Our employees were happy ,some worked twenty years for my Father,then asked to come back to work for me after they raised their family .NO Union, we always treated them respectfully even when you had to criticize their WORK ,NEVER do a personal criticism .I loved that business ..but the Government gave the JOBS away because it required lots of employees .They made deals that allowed them into a developing country where they would get into the BANKING and Insurance business if we gave them the business that employed lots more people . IT had LITTLE to do with LOW wages as most people think today ,it was Government that SOLD US OUT so they could get into Banking and Insurance in exchange .TRUMP understands it very well ,how it worked…..He’s trying to undo some of it..
