A bar-positioning member comprising a long metal wire or wire rod with at least one indentation to receive a metal bar intersectingly disposed relative to the wire. The indentation is formed by bending part of the wire and it has only one opening which opens along the longitudinal direction of the wire. The indentation has a bottom shaped approximately in conformity with the circumference of the bar. An apparatus for making a bar positioning member, as above described, comprising a pendulumlike mold member swingable about the base end thereof. The mold member has a grip to hold an intermediate portion of the wire, and the contour of the base end is shaped in conformity with the shape of the indentation.

A bar-positioning member, such as for positioning metal reinforcing bars which are to be incorporated into a concrete structure, said bar-positioning member comprising: a long metal wire or rod having a least three bar-receiving indentations formed therein at longitudinally spaced intervals for receiving metal bars which are intersectingly disposed relative to said wire, each said indentation being of a substantially U-shaped configuration which defines an opening for permitting the metal bar to be seated within the indentation, the openings defined by all of said indentations opening outwardly in the same direction, which said direction extends substantially parallel with the longitudinal direction of said wire, each said indentation being formed by bending a portion of said wire into a U shape having a pair of legs which define the respective opening therebetween, one of the legs being sidewardly displaced relative to the longitudinally extending centerline of said wire and being formed by a folded part of said wire, the other leg being formed by a nonfolded part of said wire, said other leg being substantially longitudinally aligned with said wire.
