edges of the layers is prevented by two foot plates 33 and 34 which are arranged at respectively opposite sides of removal rollers 18 and 19 and which are inclined slightly preferably by an angle of no more than 25 u00b0 with respect to the supporting surface of removal belt 20 these foot plates 33 and 34 shield the layer edges 3 39 and 3 34 against the above mentioned surges of air until they have lost their effect in this connection it has been found to be advantageous for the foot plate 33 which is inclined upwardly toward the left and is located to the side of rollers 18 and 19 which is directed away from card 1 to have in front of it an additional sheet metal piece 35 which is inclined to the supporting surface of removal belt 20 the additional plate 35 here being upwardly inclined toward the center of belt 20 and toward card 1 and having the same direction of inclination of foot plate 34 the minimum vertical distance 40 between each of plates 33 and 34 and the supporting surface of belt 20 is preferably no greater than 60 mm according to a particularly preferred embodiment of the present invention the additional plate 35 is spaced from its associated layering roller 18 by a distance 36 preferably of 10 to 50 mm by suitable selection of the value for the distance 36 between the lower edge of additional plate 35 and the surface of.
