A textile machine comprising: a bobbin holding section (54; 110) adapted to hold a yarn supplying bobbin; a drive section adapted to drive the bobbin holding section (54; 110); a drive control section adapted to send a command value to the drive section to control drive of the drive section, the drive section being a stepping motor; an origin sensor adapted to specify an origin position, which is a reference position of the bobbin holding section (54; 110); and a command value measuring section adapted to obtain the command value necessary for moving the bobbin holding section (54; 110) from the origin position to a target position as an actual measurement command value, wherein the command value is the number of pulses transmitted to drive the stepping motor, and the command value measuring section is a number-of-pulse counting section adapted to count the number of pulses, characterized in that it is adapted to be shifted by an operator to a position adjustment mode, wherein the yarn supplying bobbin or the core tube (21 a) are set in the bobbin holding section (54; 110) and the unit input section is operated by the operator to adjust the position of the bobbin holding section (54; 110) and to adjust the position of the yarn supplying bobbin or the core tube (21 a) to coincide the center of the yarn supplying bobbin or the core tube (21 a) and the center of a regulating member, and the position of the bobbin holding section (54; 110) thus aligned is defined as the target position; wherein the number-of-pulse counting section is provided for counting the steps of the stepping motor, which are necessary for the bobbin holding section (54; 110) to move from the target position to the origin position and the drive control section is further adapted to store the number of pulses counted by the number-of-pulse counting section. a bobbin holding section (54; 110) adapted to hold a yarn supplying bobbin; a drive section adapted to drive the bobbin holding section (54; 110); a drive control section adapted to send a command value to the drive section to control drive of the drive section, the drive section being a stepping motor; an origin sensor adapted to specify an origin position, which is a reference position of the bobbin holding section (54; 110); and a command value measuring section adapted to obtain the command value necessary for moving the bobbin holding section (54; 110) from the origin position to a target position as an actual measurement command value, wherein the command value is the number of pulses transmitted to drive the stepping motor, and the command value measuring section is a number-of-pulse counting section adapted to count the number of pulses, characterized in that it is adapted to be shifted by an operator to a position adjustment mode, wherein the yarn supplying bobbin or the core tube (21 a) are set in the bobbin holding section (54; 110) and the unit input section is operated by the operator to adjust the position of the bobbin holding section (54; 110) and to adjust the position of the yarn supplying bobbin or the core tube (21 a) to coincide the center of the yarn supplying bobbin or the core tube (21 a) and the center of a regulating member, and the position of the bobbin holding section (54; 110) thus aligned is defined as the target position; wherein the number-of-pulse counting section is provided for counting the steps of the stepping motor, which are necessary for the bobbin holding section (54; 110) to move from the target position to the origin position and the drive control section is further adapted to store the number of pulses counted by the number-of-pulse counting section.
