## Abstract

An apparatus for laying fiber tapes includes a deflection guide for the fiber tapes made up of pressure plates for the deflection of the tapes, which pressure plates are arranged adjacent to one another perpendicularly to the deflection axis and are resiliently supported in the pressing direction, and a frame, which is displaceable in the laying direction, for accommodating the pressure plates. The pressure rollers form grooved pulleys which engage in circumferential bearing receivers, are axially guided on each other and between lateral guide stops, and are held in bearing engagement with the bearing receivers by elastic endless belts which are guided about a bearing roller mounted in lateral retainers. The bearing receivers are resiliently supported independently from each other in the pressing direction on an abutment provided between the lateral retainers.

## Claims

### Claim 1

An apparatus for laying fiber tapes (2), comprising a deflection guide (1) for the fiber tapes (2) comprising pressure plates for deflection of the tapes, which pressure plates are arranged adjacent to one another perpendicularly to a deflection axis and are resiliently supported in a pressing direction, and comprising a frame (16), which is displaceable in a laying direction, for accommodating the pressure plates, wherein pressure rollers form grooved pulleys (6) which engage in circumferential bearing receivers (8), are axially guided on each other and between lateral guide stops (7) and are held in bearing engagement with the bearing receivers (8) by means of elastic endless belts (10) which are guided about a bearing roller (11) mounted in lateral retainers (12), and wherein the bearing receivers (8) are resiliently supported independently from each other in the pressing direction on an abutment (13) provided between the lateral retainers (12).

### Claim 2 (depends on 1)

The apparatus according to claim 1, wherein the bearing receivers (8) comprise rolling bodies (9) engaging in the grooved pulleys (6).

### Claim 3 (depends on 1)

The apparatus according to claim 1, wherein the grooved pulleys (6) are combined into individual pressure elements (15) between the pressure plates (17), which comprise a sliding surface (19) for belt deflection which is curved according to the grooved pulleys (6) and form the lateral guide stops (7), and wherein the retainers (12) arranged laterally on the pressure elements (15) displaceably engage in the pressing direction in recesses (18) of the pressure plates (17).

### Claim 4 (depends on 3)

The apparatus according to claim 3, wherein the pressure plates (17) form sliding shoes (23) which are resilient in the pressing direction and are separated from the remaining plate body by resilient webs (24).

### Claim 5 (depends on 4)

The apparatus according to claim 4, wherein the sliding shoes (23) of the pressure plates (17) are subdivided into sliding segments which are parallel to the plane of the plate and are independently resilient from each other.

### Claim 6 (depends on 1)

The apparatus according to claim 1, wherein the bearing roller (11) for the endless belts (10) can be driven by a shaft (26).
