ABSTRACT:
A machine for forming hollow articles of vitreous material includes at least one forming station provided with at least one forming means and for each forming means a neck ring means carrying a parison and including a pair of neck ring halves and a guide ring coaxially carried by the neck ring halves and rotatable relative thereto. The guide ring which engages the parison at its mouth is rotated to thereby impart to the parison a rotary motion relative to the remainder of its forming means which may comprise a split mold to thereby avoid formation of seams or fins on the finished hollow article and to improve the surface quality thereof.
