1. the guipure of bar or the brake equipment of band chuck are organized in a queuing, it is characterized in that the following fact:

  • it is formed by a single piece (1) shaping, manufacture a monomeric form, preferable by one for example the flexible material that slightly is of rubber make, has an ellipsoid core (2), center at described ellipsoid core (2), it is equipped with two symmetrical openings that are used to be coupled (3) and has two rods (4), described rod has a circular polished surface, thereby two carriages (5) are shaped to the circumference circular arc in its end, and between described two rods (4) and described core (2), be configured with two openings (6), described opening (6) is determined a displacement region of described rod (4), it determines that mode is that the described single piece (1) and a headstock (A) of locating to be arranged at the base portion office of described reel (C) at described opening (3) are coupled, make the inwall and the registration of described two carriages (5) and described reel (C) pedestal, be when described guipure or band unwinding, there is not the intervention of described drg effect, because described single piece (1) does not produce a big area of contact, thereby can reduce the friction between the described inwall of described single piece (1) and described reel (C) pedestal, because the elastic deformation of described single piece (1) can make described rod (4) shrink and thereby described carriage (5) is shunk, thereby bipartite described friction is minimized and when the withdrawal of described guipure or band, described reel (C) provides the inverse motion of the described single piece (1) that produces elastic deformation, thereby make described rod (4) reach thereby make described carriage (5) displacement, it is stood and the described inwall of described reel (C) pedestal between a friction, thereby increase the area of contact between described and make described guipure or the speed of band displacement significantly descends;

    In order to make described guipure or band have the required speed of retraction, between the described inwall of described single piece (1) and described reel (C) pedestal, provide use to a lubricated key element.
