Within a casing (10), on each side of a center plane (A), a feeding channel (26, 28) and a pressure channel (32, 34) are defined. The pressure channels (32, 34) are converging in the direction of a jet arrangement (40). Further, within the casing (10), on each side of the center plane (A), a first and a second rotatably driven feeding roll (42, 44), respectively, are disposed each between one of the feeding channels (26, 28) and the associated pressure channel (32, 34). The feeding rolls (42, 44) have their axes of rotation define a transverse plane (B). Two additional rotatably driven rolls (52, 54), disposed within the casing (10) on one side each of the center plane (A), define together with one each of the feeding rolls (42, 44) a nib (62, 64). On the side of the transverse plane (B) which is remote from the jet arrangement (40), at least a third rotatably driven feeding roll (46) is provided, having assigned to it a third inlet channel (30) and a third pressure channel (36). The third pressure channel (36) runs between the first and second feeding rolls (42, 44) to lead to the jet arrangement (40). Accordingly, the roll-type press is capable of gently processing more than two compositions at the same time for producing a filled or multi-layer strand.
