A band spooling machine (1) including a small arbor (19) with protrusions (21) that rotate with the arbor. In an embodiment, the machine includes a table (3) having side rails (7) and a single rotating arbor (19) carrying two spaced-apart pins (21) having blocks (23) that rotate freely on the pins. The arbor is preferably mounted close to one end of the machine and substantially closer to one of the side rails than to the other. The blocks prevent the blade from kinking. The machine forms the band into a pretzel having a circle part (C) divided by a central reach (R) into two lobes, and a teardrop shaped tail (T).

A deployable structure comprises: a support, a tape spring fixed to the support, able to pass from a wound configuration wound about an axis Z, to a deployed configuration, and a mobile arm able to rotate with respect to the support about the Z-axis, able to form a first contact with the tape spring so as to control the deployment of the tape spring.
