ABSTRACT:
A card feed is disclosed in which, in order to prevent machine stoppages from causing the formation of permanent impressions in a fiber web delivered from a feed chute, a displaceable delivery roller is movable on the occasion of a machine stoppage by means of a pressure-operated reciprocating actuator from an operative position, in which the fiber web is being compressed between a pair of delivery rollers, into another position in which the fiber web is no longer compressed to an extent such that a permanent impression would be produced in it during the period of machine stoppage.
