ABSTRACT:
An adjustable shear plate for blow molding equipment wherein the shear steels or plates for cutting off the neck of the blown product, usually a bottle, may be adjustable with respect to each other to compensate for wear and achieve a sharp definitive severance. The adjustable components include a shear plate holder movably mounted upon a top plate or block support, and a slide selectively positionable upon the top plate support is operated by a rotatable cam to position the shear plate holder as desired. Rotation of the cam displaces the slide to engage and adjustably position the shear plate holder and shear plates mounted thereon.
