Improved mechanism to convert rotary motion to transverse motion comprises a disc journalled to rotate about its axis and provided eccentrically with a journal, a trunnion provided with a journal, a trunnionway supporting the trunnion for transverse movement of the trunnion within the trunnion-way in opposite directions normal to such axis, and a shaft journalled to rotate within the journal provided in the disc. One end of the shaft is provided eccentrically with an axially extending pin journalled to rotate within the journal provided in the trunnion. Thereby, the pin is displaced transversely as the disc is rotated about its axis.

Mechanism to convert rotary motion to transverse motion

In bellows forming with internal and external forming rolls, the external forming roll is rigidly supported, as each convolution is formed in a blank, to permit accurate control of each convolution. The blank is indexed independently of the convolutions.
