6.2 Endless zipper device
Function
When the zipper halves are pulled by the transport clamps during the
sewing process, the feed rod 6 is pulled upwards by the zipper getting
shorter.
The feed rod switches the zipper feed on and the drive rollers 7 and 8
go on feeding the zipper until the switch rod drops and switches the
feed off again.
Thus it is made sure that there is always enough zipper material
available for sewing.
