Notes from the Past

Interrupted Perfs

Designed to give added strength to 'coil' stamps for use in stamp-vending machines.  One or more of the transverse punches are removed, giving a broken line of perforation between each stamp, and thus leaving one or more 'bridges' of unbroken paper to take the strain of operating the mechanism.  Thus in the Netherlands 1924-6 series the perforation has one punch missing at either end and two in the centre, leaving two groups of four holes.  Interrupted perfs, are also found in the experimental coils of the U.S.A.  The 1862 stamps of Peru were printed 'on the reel' on a Lecocq machine and were often rouletted with an interrupted series of cuts -- sometimes known as 'syncopated' perfs.

Lecocq Machine

This ingenious French machine printed the embossed and other issues of Peru in a continuous strip or ribbon, the stamps being either cut up or issues in lengths after being rouletted or pierced by three cuts between each pair of stamps.
