Abstract (en)

A fiber bundle condensing device (10) of a spinning machine (100) includes a condensing unit, a plurality of countershafts (20), a countershaft driving motor (103), and a shaft coupling (70). The shaft coupling (70) couples the countershafts (20) with a bolt (80). The fiber bundle condensing device (10) further includes a detected portion, a rotational position detector (30), a controller (40), and an operation unit (41). An operational range is defined as a range where a rotational position of the shaft coupling (70) is located and the bolt (80) used for a coupling main body (73) is operable from a front of the fiber bundle condensing device (10). The controller (40), when the stop command is input, controls the driving of the countershaft driving motor (103) such that the shaft coupling (70) is located in the operation range at a time when the countershafts (20) stop rotating.
