Thread Puller/T rimmer
On special request, the Pfaff 145 in Models A and B can be equipped with the time-
and cost-saving subcl. -900/06 thread puller/trimmer.
On subcl. -900/02 machines, thread trimming, needle positioning and reverse sewing
are all controlled by operating two treadles.
When the tip of the right treadle is depressed, the sewing speed increases until the
machine runs at its top speed.
At the completion of the sewing action, the needle is positioned down in the material.
Depressing the tips of both treadles switches the machine to reverse sewing.
When you depress the heel of the right treadle, both threads are trimmed and the
needle is raised to facilitate the removal of the work.
The various treadle operations can be seen from the sketch below.
