Definitions

  • the object of the present invention is a spindle tape drive spinning machine of a spinning line for obtaining bobbins of yarn from spools of roving, which usually originate from a roving frame.
  • a spinning machine is able to operate spools of roving in order to obtain yarn bobbins therefrom after having drawn and twisted the roving.
  • the spinning machine consists of a portal that extends along a longitudinal axis, on which the roving spools are hung, a drawing device arrangement beneath the portal and formed by a set of cylinders having a longitudinal extension, between which the roving passes in order to be drawn, and two opposite banks, each supporting the spindles, in a row along the longitudinal axis, which rotate about their vertical axis, on which the drawn and twisted yarn is wound.
  • a handling device which comprises a main shaft that extends along the entire machine and is provided with a plurality of pulleys that are longitudinally spaced apart. Each pulley supports a belt (or tape), which engages with four spindles, two for each bank (the Anglo- Saxon name for this type of spinning machine is, in fact, "four-spindle spinning machine") .
  • the handling device then comprises an electric motor, which is housed in the tail of the spinning machine, for rotating the main shaft .
  • the object of the present invention is to design a spindle tape drive spinning machine that meets the needs of the sector and overcomes the disadvantages mentioned with reference to the prior art.
  • Fig. 2 is a schematic lateral view of the spindle tape drive spinning machine in Fig. 1;
