Abstract
A substantially funnel-shaped constricting fiber chute or shaft possesses at its lower portion blade springs forming a diaphragm or the like. These blade springs extend at an acute angle with respect to the lengthwise axis of the fiber chute. At their free ends these blade springs delimit an exit or outlet opening, by means of which the fiber chute opens into a container, such as a bag or sack or the like which is exchangeably secured at such fiber chute. A driveable plunger arranged coaxially with respect to the fiber chute possesses a plunger head which tapers in the outlet direction. The plunger head possesses a toothed or serrated band. Upon penetration of the plunger into the fiber chute or shaft the plunger head compacts fibers which have collected in the fiber chute and expresses such, while further compacting the same, into the sack. The equipment is particularly suitable for use at a fiber separator at which the fibers separated from a transport air current or stream drop into the fiber chute.
