Abstract: An apparatus for dispensing fibers for use in the making of fibrous concrete is disclosed in which the fibers are dispensed from an elongated web which has been coiled with the fibers placed within the layers of the coils. The individual concrete reinforcing fibers are deposited in a uniform layer on an elongated web, which is then coiled to form a package. The dispensing device supports a spindle on which the coiled package is placed. The end of the coil of the package is wound around a second spindle which is driven by a rotary motor, and as the web is progressively uncoiled and wound around this second spindle, the fibers are discharged from between the convolutions of the coil.

Abstract: High modulus asperities are incorporated into a fluoroelastomer matrix to provide a material which, when cured, exhibits high, stable coefficients of friction over a wide temperature range.

Abstract: Disclosed is a method of mixing fiber reinforced concrete without the formation of fiber balls therein. The method includes the steps of depositing a uniform layer of substantially individual concrete reinforcing fibers on an elongated web, coiling the web to contain the fibers, locating the coiled web in proximity to a concrete mixing device, and progressively uncoiling the web at a predetermined rate to discharge the layer of fibers therefrom into the mixer. Also disclosed is a unique package for concrete reinforcing fibers for use in connection with the above method.
