An apparatus for measuring the thickness of a plurality of side-by-side running slivers includes a supporting surface guiding the side-by-side running slivers thereon in a single plane; a holding member; and a plurality of sensor elements movably secured to the holding member to be movable in a direction transverse to the plane. Each sliver is contacted by a separate sensor element for causing excursions thereof by thickness fluctuations of the running sliver. Each sensor element is yieldingly pressed against a respective sliver, and each sensor element cooperates with the supporting surface for pressing the running slivers against the supporting surface. An adding device adds the excursions of the sensor elements, and a transducer converts the excursion values into electric pulses.

A control and regulating device is connected to the measuring elements for receiving the signals therefrom. Movable wall elements are arranged side-by-side parallel to the reserve chute width and form part of at least one of the reserve chute walls. Setting members are connected to the wall elements for moving the wall elements in sections in a direction parallel to the reserve chute depth for varying the size thereof.

A feeding device for advancing fiber material includes a driven feed roll; a support element immovably held during operation and extending spaced from and generally parallel to the feed roll; and a feed tray assembly composed of a plurality of side-by-side positioned feed tray segments. Each feed tray segment is of a resilient material and has a first portion (end portion) immovably affixed to the support element and a movable, second portion having a surface oriented toward the feed roll and cooperating therewith for advancing the fiber material passing through a nip defined between the feed roll and each feed tray segment. The second portion of each feed tray segment is displaceable toward and away from the feed roll.
