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.
Apparatus is provided comprising means for producing continuous lengths of mono filament, a molding plant for receiving mono filament, cutting it into short lengths, and combining it with resin compounds, and then forming batches of fiber-reinforced compound under compression; means for producing resin bonded fiber mats comprising a conveyor belt for receiving mono filament and for depositing resin thereon, for cutting pieces of mat from the mat thereby produced, associating batches of fiber-reinforced compound with pieces of the fiber mat, and delivering the fiber mat pieces together with the synthetic resin compound batches on them to a molding press.
