    Abstract: In the process for producing a leaf spring which, at least in essential springy sections, is composed of a fiber-reinforced plastic material, a continuous web (9) is formed comprised of reinforcing fibers, appropriately in the form of fiber rovings or fibrous tissues, with the reinforcing fibers being appropriately impacted or impregnated with a hardenable plastic substance, whereupon intermediate layer pieces (37) are appropriately put on the continuous web (9). The continuous web (9) is then wound up in several layers (36) on a rotating pick-up device (27) into a continuous reel (35), with the intermediate layer pieces (37) arranging themselves in the continuous reel (35) between contiguous superposed continuous web layers (36); the continuous reel (35) is then placed in a mold in such a manner that it adjoins along its entire periphery the barrel-shaped contact area of the mold chamber.
