The “Hercules” Steel Rule Cutter.
The Multiform Rule Bender is an excellent device for bending steel rule. It is made by the J. A. Richards Co., of Kalamazoo, Mich. This concern also makes steel rule cutters, combination rule benders, box maker’s special saws, etc.
The “Eureka” Steel Rule Bender.
The “Eureka” Rule Press, or steel rule bender, is another great time-saving device for any folding box factory. This machine is made by J. F. Helmold & Brother, of Chicago. This Rule Press, with its equipment of molds, is capable of bending steel rule to any of the odd shapes required in steel rule dies for folding boxes or cartons.
Some die-makers do all of the steel rule bending with the aid of a powerful vise and pliers of various sizes. The steel cutting rule is heated by means of a gas flame so that the rule may be bent more easily. When working with the heated rule the die-maker wears heavy canvas gloves to protect his hands from the hot rule. After the heated rule has been bent to the wanted shape, heat the rule again and immerse in cod oil. This re-tempers the rule.
