?bers and more especially medium length ?bers
of various kinds such as wool, ?ax, hemp, silk
waste, etc.
The invention has for its object the provision of ‘a novel machine of the indicated class which

The novel comber comprises a supporting frame
I5 of suitable type and dimensions on which the
mechanical elements of the machine are mounted.
At its inlet end the comber is provided‘ with feed- '
