Manufacture of Backing For Bows
In the early 'thirties, I had invented a method of making silk backing
for bows. The silk was thrown in threads, without twist, and wound on
large spools. I ran these threads through a glue bath and laid it on
two-foot diameter drums. A guide, traveling across the drum laid it on.
I used two and three layers of the silk. After it had dried over night,
I cut the sheet at a split in the drum and pealed off a sheet that was
twelve inches wide and six feet long. I sold these sheets to tackle
makers all over the United States.
During the period starting in 1939, and up until the supply of silk was
cut off due to the war with Japan, I manufactured 1,700 of these sheets.
This was enough to back 11,900 bows. I had eight of the drums and could
make up that many sheets in one evening. I did this work in our apartment
My wife took care of the shipments and billing.
At the close of the war, I had found that Fortisan was a better material
for this purpose than the silk and beginning in 1946, I manufactured
Fortisan sheets. I continued this until the war in Korea, when the U.S.
Government took all the Fortisan that was being manufactured. During
this period, I made 4,351 of these sheets, enough to back 30,457 bows.
The total number of silk and Fortisan sheets was 6,051 or enough to back
