(57) A yarn winding unit (1) is a device for forming a package (205). A cradle (29) includes a winding bobbin clamping section (32a, 32b) for sandwiching and holding the package (205), and a package brake (51) for controlling holding force and brake force application of the winding bobbin clamping section (32a, 32b) according to the supplied air pressure. An actuation air path (40) includes a first air supply path (41) for supplying a first air for supplying a holding force for the package brake (51) to rotatably support the package (205) through the winding bobbin clamping section (32a, 32b) to the package brake (51), and a second air supply path (42) for supplying a second air for the package brake (51) to apply brake force and stop the package (205) through the winding bobbin clamping section (32a, 32b) to the package brake (51).
