ABSTRACT:
A fastening apparatus which includes a supporting column with a working station installed on one side at the lower end thereof. Upper and lower annular rails are supported on and coaxially surround the upper portion of the column with a portion of the annular rails being vertically movable. Plural multi-spindle fastening heads are supported on the rails and movable circularly there around. An indexing device is mounted on the upper portion of the column for selectively engaging in moving a desired one of the heads to a position above the working station where the vertically movable portion of the annular rails is provided. A connecting head supported by the upper portion of the column is engageable with the fastening head that is positioned over the working station for supplying power thereto from a separate power source. The movable portion of the annular rails raises and lowers the selected fastening head to perform the fastening operations on the work piece at the working station.
