Abstract:
A ring twisting and winding machine comprising:a) a function programmer having: (i) an electronic control card for controlling working parameters of the unitary production module; (ii) a keyboard for introducing the working parameters; and (iii) a display for displaying the working parameters, said working parameters including feeding speed, speed and sequence of movement of the raing rail unit and the speed and turning direction of said spindle; b) an electric rack comprising electric control elements, said electric control elements including at least one frequency variator; c) a spindle unit for twisting and winding a thread on a bobbin, d) a first electric motor for driving said spindle unit, the first electric motor being connected to a first said frequency variator, such that a first real turning speed is controlled by said function programmer and said first frequency variator; e) an inductive detector of said first electric motor, said inductive detector enabling the function programmer to read said first real turning speed of said first electric motor; f) a ring rail unit for vertically reciprocating a ring holder support and a control ring support; g) a feeding unit to supply thread to said spindle unit at a regular linear speed; h) a module frame comprising a plurality of steel plates, with a bend in the lower parts of the steel plates, to house module supports and module leveling elements; and i) a second electric motor controlled by a second frequency variator, said second electric motor driving the ring rail unit, said second electric motor determining a linear speed and course length of the ring rail unit, said second electric motor having a pulse counter for reading a second real turning speed of the second electric motor and for transmitting the second real turning to the function programmer, the second frequency variator being controlled by the function programmer and receiving function programmer indications from a plurality of inductive detectors about vertical positions of the supports, the ring rail unit further being for guiding the thread for winding the thread onto the bobbin.
