Definitions

  • the invention is based on an already known method (EP 0 428 826 A1) in which the roving machine is stopped in one position or runs out in a position in which the press fingers are just below the upper reversal point of the last layer of turns on the coil, i.e.
  • the coil bank is lowered into an area in which the press fingers are above the cylindrical regions of the bobbins, then the bobbins are rotated forward by at least half a turn and, depending on the nature of the material to be processed, the fuses between the drafting system and the pressing fingers are loosened and the non-rotating wings and bobbins are moved axially relative to one another for the final separation process that the pressing fingers are guided downwards, the fuses being separated at the level of the cylindrical regions of the coils.
  • the bobbin bank is lowered into the doffing position after the fuses have been separated, the roving bobbins being rotated forward by an angle of rotation of at least 5 ° during the lowering.
  • the fusible material is “heaped” in the next method step. This means that the drafting systems 13 are switched to delivery (arrow 23) for a short time, as indicated in FIG. 4. The other machine components stand still at this moment.
  • the pre-spinning machine which enables the use of the above-described method, either has separate drives for the drafting systems, the spindles and the wings, or it is equipped with coupling devices which enable the individual machine components to be selectively switched on.

Claims (2)

  1. Procédé pour sectionner les mèches de bobines de mèche (6) produites sur des bancs à broches (1), qui conduit à des bobines de mèche, dans lesquelles les extrémités libres des mèches reposent au moins partiellement sur les cônes de bobinage (16) et dans lequel le banc à broches (1) est immobilisé dans une position ou ralentit dans une position, dans laquelle les doigts presseurs (5) s'appuient contre les zones cylindriques (18) des bobines de mèche (6); puis le banc de bobines (8) est abaissé jusqu'à une zone dans laquelle les doigts presseurs (5) se trouvent au-dessus des zones cylindriques (18) des bobines de mèche, les bobines de mèche (6) étant simultanément tournées en arrière d'un angle de rotation qui suffit pour dérouler la longueur de mèche nécessaire lors du mouvement d'abaissement (22) du banc de bobines (8); ensuite, les bobines de mèche (6) sont tournées vers l'avant d'au moins un demi-tour; en mettant en marche le banc d'étirage (13), une quantité prédéterminée de matière de mèche est accumulée et à la suite de quoi le banc de bobines (8) est levé et ainsi les mèches (15) sont sectionnées à hauteur de la zone cylindrique (18) des bobines de mèche (6).
  2. Procédé selon la revendication 1, caractérisé en ce que le banc de bobines (8) est abaissé après le sectionnement des mèches (15) dans la position d'enlèvement et ainsi les bobines de mèche (6) sont tournées vers l'avant d'un angle de rotation d'au moins 5°.
