Description: |
| Straightening machines pass metal bar stock between a pair of rollers to remove irregularities such as bends and wrinkles. The pressure required normally leads to the use of larger diameter rolls, but larger rolls are less effective at removing short bends or wrinkles. In this patent, Mergenthaler proposes smaller-diameter roles with substantially journalling (bearing surfaces) to minimize deflection.Mergenthaler invented the linotype machine, and this particular patent is one of a series granted just a couple of weeks after the inventor's death from tuberculosis. Presumably this metal straightening machine is in some way relevant to the linotype process, perhaps for the processing of brass bar stock that will be turned into "matrices", the strips of brass that each have the female image of a character on one end and that are assembled by the linotype machine into lines used to cast a line of type. |
