    摘要: The invention relates to apparatus and method for forming a sheet molding compound. The sheet molding compound is linearly advanced. A moveable upper surface formed by a belt passing around a series of driven rollers is adapted to contact the upper surface of the sheet molding compound. The belt is held in biased relationship to the sheet molding compound. In one arrangement of the invention, the sheet molding compound is caused to undulate vertically while retained in compression to induce one form of shear effect. In still another embodiment, as the molding compound is passed in vertically undulating fashion between compressing mesh belts, one of the belts is driven at a fixed rate, while the opposite is driven at rates oscillating above and below the fixed rate.

    摘要: The invention is disclosed herein in a method and apparatus for manufacturing a glass fiber mat. A fiber collecting surface is moved past a fiber deposition station. Glass fibers are provided, deposited, and processed in a mat-like mass on the collecting surface. Data is processed in a data processing means to obtain values representing the difference between the actual conditions and the desired conditions of the plurality of variables involved in the providing, depositing, and processing of the glass fibers to obtain a finished glass fiber mat with desired characteristics. The data processing means provides an operation change signal for at least one of the variables indicating the change necessary in a final control device for that one variable to eliminate a deviation between an actual and a desired condition for the variable. The operation change signal is stored in a supervisory control for the one variable, enabling more time for processing of data in the data processing means for the other variables being controlled. The operation of the final control device for the one variable is modified an amount dictated by the operation change signal stored in the supervisory control.

    摘要: The specification describes a process for making a sheet molding compound wherein a layer of resin-filler paste that includes a thickening agent and a hardening catalyst is put down upon a first layer of sheet material; a layer of glass fibers that are sized with a material which induces wet out is placed thereon; following which another layer of the resin-filler paste containing the catalyst is placed thereon and covered by a second layer of sheet material. The sandwich thus formed is fed into the bite of rollers which squeeze out air and compress the resinfiller paste around the sized fibers, following which the composite is placed under further compaction that includes a perforating means which forces needle-like members through at least one layer of the sheet material, through the resin-filled paste, and into the layer of fibers for the removal of remaining entrapped air. The glass fibers which are used are sized with a material that includes both a hardening resin, and a nonhardening resin. Specifically, the fibers are coated with an unsaturated polyester resin and a saturated polyester resin which are preferably deposited on the glass fibers as emulsified particles.
