Помогите пож-та перевести словосочет [rolling pin]. Здесь это не скалка, а деталь бумагоделательной машины на целлюлозно-бумажном комбинате, но как она точно наз-ся? Контекст:
Much of the material at the mill was salvaged to be recycled. Most of the steel and about one million pounds of copper wire would be recycled and 200 tons of concrete would be crushed into smaller pieces for reuse. And 200 tons of debris would go to landfills. Work continued smoothly until Staton ran into a slight problem—actually a big problem; namely how to dispose of four solid cast iron [rolling pins], each measuring 20 feet long and 40 inches in diameter. These [rollings pins] had been used to press the pulp into paper. Each pin had an outer shell casing 2 to 3 inches thick which measured 80 to 90 on the Rockwell scale of hardness. Each pin weighed approximately 100,000 pounds or 50 tons.
