The thread blocking device consists of 2 moving parts, an upper plastic part and a lower
metal part; both are connected to an axis and tensioned using a spring.
1- Adjusting the shape of the lower thread blocking device.
The shape of the lower thread blocking device is shown on photos 19 et 20. Seen in profile,
it should be at a slight angle to the upper part so that it is its tip which exercises maximum
pressure on the thread. Similarlry, seen from the font, it should be at an angle with the up-
per part in order to ensure that the thread is blocked as close as possible to the eyelet
through which the thread is fed. These adjustments are made using pliers.
2- Adjusting the position of the lower thread blocking device.
The lower thread blocking device must pass, as the pincers close, laterally as close as possi-
ble to the eyelet feeding the thread through (photo 21) and, in height, slightly above the
hole through which the thread passes (photo 22).
Any lateral adjustment should be made using pliers and any height adjustment using the
blade of a screw driver:
a- If the lower thread blocking device passes too high, reshape it backwards (under spring
blade n°20C) by immobilising it with the tip of a screw driver and pressing down on the
front part with one's fingers (photo 23)
b- If it passes too low, push it up by levering it with a screw driver (photo 24).
