In a bobbin machine a spindle racking mechanism is provided wherein an upper component, which is the part actually racking the spindles, presents, besides a revolving plate and a tapered spider pinion, an intermediate disk acting as a cam and having two diametrically opposed indentations and a rim, curved in this case; while a second component, a carrier of tapered satellite pinions, is formed by a hollow body, having the outer stop housings in a cross design, and divided into two fitted parts holding a support, with arms also in a cross shape, for the inner pinions, a third component being formed by a driving cylindrical gear, not only provided with the last tapered satellite pinion, but also with an eccentric cam in the opposite side, working together with a connecting rod connected to the coupling and driving system of a bushing rotatable parallel to the stationary shaft running through the three basic components above named, the rotatable bushing carrying the pallet fork with two arms at different levels controlling the movements of the entire mechanism in the detention and racking of the bobbins, a locking and driving system being provided with a ratchet device which can be operated either electrically or mechanically by remote control, in the first case by means of an electronic circuit plugged into a programmer- computer; and in the second case, by means of a Jacquard machine attached to the bobbin machine by conventional means. <IMAGE> |
