ABSTRACT:
A method and a device for introducing reinforcing strands into a vertical mold through the open upper end thereof. An array of strand material is positioned to extend across the open end of a mold and an insertion device is lowered into the mold. The insertion device engages the strand material during its downward motion and draws an appropriate amount of such material from a continuous supply thereof to give a strand reinforcement of elongate U-shape within the mold. A reciprocable carriage is provided whereby the leading end of the strand is presented to a clamp at a remote side of the mold opening, the carriage having a selectively operable clamp thereon for engagement with the strand during movement of the carriage toward the clamp.
