Definitions

  • the effect which is achieved byvarying the distance between the guiding rods isthat the less the distance apart is, the greater will be the pressure which is exerted by the belts upon the roving and, at the same time, the greater is the distance through which the belts and roving are in contact, the consequence of which is that the point at which the belts deliver the roving to the drawing cylinders is advanced closer to the cylinders.
  • the greater the distance between the gulding rods 15 the less will be the pressure exerted by the belts and their contact is of less extension, and the roving is consequently delivered at a greater distance from the drawing cylinders.
  • the distance between the guiding rods must be, however, always substantially greater than the thickness of the two belts together, as otherwise, the two rods would stop-the functioning of the belts in a 7 regular manner.
  • the improvement forming the subject matter of this invention permits the variation with great facility of the space or distance between the guide rods according to the class of fibre which is going to be treated without having to change the frame or the drawing mechanism.
  • the improvement forming the subject'matter of this invention consists essentially in arranging'the two guide rods to form one single Ell-shaped piece and mounting this piece in the frame in such a manner that it can be easily changed for another, the rods of which are at the same or at a different distance apart, in suchwise that by merely changing the piece constituting the guide rods, without touching any other element of the drawing mechanism, said mechanism can be adapted to the class of fibres and to the type of work to be carried out at the time.
  • the piece forming the pair of guide rods may be provided with a handle-like por tion so as to facilitate its manipulation.
  • Figure 1 is a lateral elevation of the mechanism, excluding the drawing. cylinders.
  • Figure 2 represents the same mechanism in front elevation, that is to say, the part I where the belts deliver the roving to the drawing? cylinders. i
  • igures 3 and 4 are modifications in the form of the U-shaped element which constitutes the guide rods for the belts
  • I Figure 5 is a diagram on a larger scale showing the influence which the space between the guide rods has upon theconducting of theroving to the drawing cylinders.
  • the drawing mechanism of a type already known, is composed of a frame formed by two lateral plates 1, 2 braced together by means of transverse members 10 and 11, the latter having, furthermore, for its object to guide the roving fibres for its entrance into the drawing mechanism.
  • This frame rests upon rollers 5 and 6 which actuate two endless belts 3 and 4 which conduct the roving to the drawing cylinders, not shown in Figures 1 and 2.
  • the foremost parts of said belts 3 and 4 areguided by two rods or guiding cylinders 8 and 9 which are non-rotary and arranged within the front loops of the belts.
  • the two guide rods 8 and 9 are so made as to form one single U-shaped piece, as shown in Figures 1 and 2, which piece is supported in the frame by its lower rod 9 being located in a notch 13 in the frame, whilst the upper rod 8 is simply placed against theupright part 16 of the same frame.
  • the said belts 3 and 4 hold the piece 8, 9 against the front edge of the frame and the slot 13 thereof prevents A Order also to avoid displacement in a trans- Verse direction of said piece 8, 9 the lower rod 9 has its end 15 bent downwards, thus preventing displacement towards the .left of Figure 2.
  • ter of this invention permits of having an assortment of pieces 8, 9 with different distances between the guide rods and, in each case, of selecting that distance which is most suitable for the .Work to be done, as the apparatus can thus be easily graduated to do a definite class of'work or a determined piece of work, without having to vary to the slightest degree the frame and neither the cylinders nor the belts.
  • FIG 5 there is shown diagrammatically the effect produced in themechanism by varying the distance between the two guide rods 8, 9.
  • the belts 3, 4 each form in the front part a curve of larger radius and the belts separate at the point 20 for example.
  • the belts take up the positions 30, 40 forming curves of smaller radii and they are in contact with each other up to the point 21.
  • a drawing mechanism for textile rovings provided with endless belts, having in combination a frame which guides two belts laterally and two guiding rods supported on said frame which guide internally the front loops of the belts, said two guiding rods being united forming one single U-shaped piece in order that the distance apart of the rods may be invariable and that the rods can be easily retracted from the frame.
  • a drawing mechanism for textile rovings with endless belts having a guiding frame for the belts and two guiding rods forming a single U-shaped guide the front loops of the belts, said U- shaped piece being provided with a handle like element directed upwards to facilitate the catching hold and placing it upon or withdrawing it from the mechanism.
  • a drawing mechanism for textile rovings with endless belts having a guiding frame for the belts and two guiding rods forming a single U-shaped piece to internally guide the front loops of the belts, said U- shaped piece having its lower rod or branch bent at the end in order that when once placed in position the piece cannot loosen itself from the mechanism.
  • side plates having notches therein, rolls carried by said side plates, belts trained about said rolls and a unitary demountable piece composed of two spaced rods adapted to be mounted crosswise of said side frames and through the belts, one of said rods engaging in the notches of the frame and the other of the rods abutting against upright portions of the frames.
