Abstract
An apparatus (25) for transporting pre-measured quantities of fibers in a plurality of containers (13), separated by a plurality of webs (14), joining the containers together at spaced intervals, to a mixer (22) for cementitious materials, the apparatus comprising a conveying assembly (26), the containers therethrough; a counter assembly (28); a web slitting assembly (29); and a process controller (30), which activates the web slitting assembly in response to input from the counter assembly, in order to sever a determined number of the containers from the webs for conveyance into the mixer. A method for conveying pre-measured quantities of fibers suitable for the reinforcement of cementitious materials to a mixing apparatus is also provided as well as a train for providing pre-measured quantities of fiber comprising a plurality of containers containing the fibers; and a plurality of webs, joining the containers together at spaced intervals.
