Nach oben zu öffnendes Führungslager für einen Scherenmechanismus

摘要

A shear mechanism for shearing discrete gobs from at least one runner of molten glass has a shear assembly which is displaceable back and forth along a pair of guide rails. The assembly has at least one shear supported on an arm which has a bearing at one side which is operatively associated with one of the guide rails. The support bearing has a lower bearing surface which engages the bottom of the guide rail and an upper bearing surface which supports the top surface and the lower bearing surface can be displaced away from the guide rail by operating a release which is located on the top of the bearing.
