Device for separating one or more strands of molten glass into individual glass items

摘要

A device for separating one or more strands of molten glass into individual posts has a number of pairs of shearing blades corresponding to the number of strands to be separated, one blade of each pair being arranged on a first supporting arm and the other on a second arm and the arms being movable towards and away from each other, and a drive unit for the to and fro movements of the arms. In order to ensure complete simultaneity of the movement of the co-operating components of the device and high positioning precision, the drive unit has a bidirectionally operable crankshaft by which two crank journals mutually staggered by 180 DEG can be moved, the first of which is operationally connected to the first supporting arm via a first connecting rod and the second to the second arm via a second connecting rod.
