Abstract: A process is provided for manufacturing blanks comprising the production of a batch of fiber-reinforced synthetic resin compound, the production of a piece of fiber mat, depositing the batch of compound onto the piece of fiber mat, and conveying them together into a press for molding them together. In such a process, the initial step of producing the fiber-reinforced synthetic resin compounds and in producing the fiber mat is the production of a running length of fiber, which is then either cut and combined with resin compounds for the production of the noted batches, or placed on a conveyor and combined with additional compound; the process includes operating the fiber producing apparatus and delivering the fibers produced to a cutting means of the equipment for producing the fiber-reinforced synthetic resin compounds for a first period of time and then delivering the fiber to the conveyor for the production of a fiber mat for a second period of time.
