    Abstract: This invention relates to rolling of annular workpieces by means of apparatus comprising a pressure roller, a mandrel which squeezes the workpiece against the pressure roller and backing rollers on which the mandrel rolls in line contact. Either the backing rollers or the pressure roller can be formed in two parts which can be adjusted towards and away from each other, either before or during rolling.

    Abstract: This invention relates to a method of forming headed articles such as bolts from round bar. The bar is rotated in the throat between two rollers and has a part extending beyond the roller surface. A stylus is pressed against the face of the projecting end to form an indentation in this face of the rolling bar and as the indentation increases in size a head is formed on the bar. The head can be subjected to further working if necessary.

    Abstract translation: 本发明涉及一种从圆棒形成诸如螺栓的头部制品的方法。 杆在两个辊之间的喉部中旋转,并且具有延伸超过辊表面的部分。 触针压在突出端的表面上,以在滚动条的该表面上形成凹陷,并且随着压痕的尺寸增大,在杆上形成头部。 必要时,头部可以进行进一步的工作。
