ABSTRACT:
A concrete and wire placement mechanism mounted for bodily movement relative to a form is provided with a tube for conveying concrete to the form and includes driven elements supported by the tube operative to feed, cut and to throw off discrete cut lengths of reinforcing wire on the order of at least 10 inches in length for embedment in axially aligned and ordered arrays in layers of concrete deposited in the form as the mechanism moves relative to the form. In one embodiment for making utility poles the concrete form is a hollow, elongated substantially-cylindrical member which is axially movable to and fro and which is rotated about its axis during axial movement thereof.
