PURPOSE:To make a synchronizing device lightweight and as well to cut long length articles into a specified fixed length with a minimum error, by utilizing a synchronizing link device instead of a synchronizing train. CONSTITUTION:A synchronizing link 5 is interposed by means of coupling shafts 19a, 19b between arms 8a, 8b making a certain angle with respect to the bent direction of driven crankshafts 12, 6, 13, which are projected from driven shafts 12, 13. The effect of synchronization becomes maximum at an angle of 90 deg.. With this arrangement which is simple and light weight in comparison with the conventional arrangement having a gear train, long length materials such as, for example, pipes, shape steels, etc. may be cut into a fixed length with a small error. |
