摘要

An apparatus for feeding and weighing textile fibers includes a weighing scale container having an open end chargeable with fiber material; an upper feed chute having an upper end chargeable with fiber material and a lower end; a withdrawing roll obturating the lower end; a first drive for slowly rotating the withdrawing roll; a feed tray cooperating with the withdrawing roll and defining a nip into which fiber material is drawn from the upper feed chute and from which the fiber material is discharged; an opening roll arranged immediately at the nip for receiving the fiber material discharged from the nip; a second drive for rapidly rotating the opening roll for tearing fiber material from the nip and for opening and discharging the fiber material; a lower feed chute having an upper end receiving fiber material discharged from the opening roll and a lower end; a movable shutoff gate situated at the lower end of the lower feed chute for opening and closing the lower feed chute; and a third drive for moving the shutoff gate.
