ABSTRACT:
A yarn making machine assembly includes a yarn spinning chamber; a feed table adapted to support a silver thereon; a feed roller having a periphery defining, with the feed table, a clearance through which the sliver is adapted to pass; an rpm-variable motor connected to the feed roller for rotating it to advance the sliver; an opening roller arranged adjacent the clearance to receive the sliver and to break it up into fibers; a sliver thickness sensor including the feed roller and/or the feed table to execute excursions in response to thickness variations in the sliver running through the clearance; a device for generating an electric signal as a function of the excursions; a regulator for receiving the electric signal and for emitting a setting signal as a function of a difference between desired and actual thickness values of the sliver; and a device for applying a signal, representing the setting signal, to the motor for varying the rpm thereof to thus alter the rotational speed of the feed roller, whereby the thickness of the sliver admitted to the opening roller from the clearance is rendered uniform.
