  • Patent number: 5201979
    Abstract: Method and apparatus for manufacturing a sheet-prepreg reinforced with fibers wherein a sheet of fibers such as warp or woven fibers such as fabrics is conveyed between a pair of band belts one of which is coated with a film of thermoplastic resin which has been heated higher than its softening point to enhance resin-impregnating efficiency and prevent the impregnated resin from contacting air. Further, when the sheet of fibers or woven fibers is conveyed in this manner, the molten resin is not maintained on the manufacturing line, thereby preventing it from being deteriorated by heat. The apparatus can be thus kept under operation for a long time and the sheet-prepreg reinforced with the fibers can be made much higher in quality and the deterioration of the impregnated resin can be further delayed.

    Abstract: A restraining device is used in a dry kiln with a load of green lumber in order to reduce warpage during drying and cooling. A single restraint device is comprised of a pair of inverted leaf springs joined together at their centers and having a strap extending from one end of the top spring about the load of lumber and terminating at the other end of the top spring together with a tensioning device for the strap. Before the load of lumber is placed in the dry kiln, the tensioning device will draw down both the bottom and top leaf springs close to the load where the tensioning device will lock them in place. During drying, as the load shrinks, the top spring will be relaxed while the bottom spring will maintain a force across the width of the load, thereby substantially reducing warp.
