On plate S1111, the bridges are 121mm (approximately 4 1/2 inches) apart.  The bridges repeat about every 5 1/2 stamps.
Click on the above photo for a larger scan.  The scans have been digitally altered to make the bridges clearer.
The above scans (left side) illustrate the bridges between the coil rows that hold them together. The right scan shows the vertical die cutting.  Click on the photos for a larger, more detailed scan.
These stamps are being supplied to post offices in a stick of 5 and 10 coils.  There are connecting bridges between each row to hold the coils together inside the stick. 

The bridges are also on the leader strips on some coils.   I have not been able to determine a pattern as to the placement of the bridges in various rows in relation to bridges on other rows.

I'm not familiar with the process used to create these bridges.  It's possible that the coils were slit with a wheel that had a break in it to allow for the bridge.  It would be interesting to know how they created the bridges.

Because of the bridges, it is possible to create a block of attached vertical coils as I have done above.   Depending on the placement of the bridge, vertical pairs or blocks of 4 can easily be created.  Click on the above scan for more detail.
