If I had a clue where the breaker box was located I'd have turned the lights on, not off!
The main difference between a breaker card and a finisher card is that the latter is fitted with finer pins, that it contains two doffing rollers, and that it usually possesses a greater number of pairs of workers and strippers - a full circular finisher card having four sets.
In an ordinary case, the total doublings in jute from the breaker card to the end of the second drawing is ninety-six: 12 X 4 X 2 = 96; and if the slivers were made thinner and more of them used the ultimate result would naturally be improved.
These pins are much finer than those of the breaker and finisher cards, consequently the fibres are more thoroughly separated.
By adjustment of the contact breaker the series of sparks may be made to fit more or less perfectly with the formation of the drops.
