2. Description of the Related Art A known device (D) disposed in front of a card is used.
In E-OS3413595), the feed roller exists above the opening roller located above the feed box. The feed roller is supplied with the fiber mass by a dish plate consisting of closely arranged dish plate sections. Each dish plate section is rotatable about an axis parallel to the rollers. The individual dish plate sections are rotated by the fiber mass by an amount corresponding to the mass of fiber mass loaded on the dish plate section. Each dish plate section is connected to an electromagnet, which is connected to the control device via a conductor. The dish plate section acts as sensors, which operate the controller.
The air permeable wall of the reserve box is closed by a series of slides. These slides can be individually raised and lowered by electromagnets connected to the control device via wires.

The disadvantage of this device is that it has an air outlet which can be raised and lowered as an adjusting member, and that the conveying air flow and the compressed air flow for the fiber mass fluctuate due to the expansion or contraction of the air outlet surface. It is. A further disadvantage is that it delays the setting of the fiber mass fleece on an unfavorable scale, especially for thickness variations. In this known device, the height of the fiber mass column in the box is lowered in the region of the narrow box wall on the side. Since the height of the walls of the fiber mass columns in the box is not uniform over the width of the machine, it is not possible, in particular, for use in wide card feeders, for example, 3 m or more in width.
