  • Pinch bar and parison separation method
    Patent number: 7384260
    Abstract: A parison pinching and separating system for attaching to first and second mold halves is disclosed. Each mold half has first and second cavities. The system includes a first pinch bar for attaching to the first cavity of the first mold half, a first pinch bar for attaching to the second cavity of the first mold half, a second pinch bar for attaching to the first cavity of the second mold half, and a second pinch bar for attaching to the second cavity of the second mold half. Each pinch bar has a surface and a protrusion that extends from the surface. The protrusions of the pinch bars associated with first cavity are positioned for pinching a parison when the first and second mold halves close. The protrusion associated with the second cavity are positioned for pinching a parison when the first and second mold halves close.
