Abstract

The invention relates to an improvement in spinning pots composed of a cylindrical shell 1 reinforced with a lower bottom and an upper metal flange 2. The pot is characterized by the fact that the collar 2 has a large molding 6 with a rounded vertical section projecting towards the axis of the pot and consequently reducing the inlet section of the latter. Application to improving the filling of pots. (CF DRAWING IN BOPI)

Description

Technical area.

  The present invention relates to an improvement

  spinning pots composed of a lower bottom and an upper metal collar, said pot being intended to receive a wick of textile fiber which stacks in the form of hypocycloids with a diameter slightly less than half the diameter of the pot, leaving a small central chimney, when said pot rests on a turntable and said wick is fed at the output of a combing machine, a carding machine or the like including a loveur debit the wick by rotating it around of a vertical axis, movement in which said wick rubs

  periodically against the collar.

Problem.

  It is a question of putting the maximum of materials, that is to say of lengths of locks, inside a

  spinning pot given to space the manual interventions

  nuelles which are obviously expensive.

  State of the art and disadvantages.

  The trend has been for some time to increase the size of spinning pots. However, the machines are designed for a given pot size

  because the loveur, which is under the dispensing cap

  tion, distributes the wick according to a diameter which corresponds to a small half of the diameter of the pot. In addition, the height of the lover above the turntable is a fixed dimension that also depends on the size of the pot. In other words, each machine has its own pot size and

  it is not possible to increase the capacity of these pots.

  The present invention is intended to remedy

to these disadvantages.

Presentation of the invention.

  The spinning jars of the invention are characterized

  mainly due to the fact that the collar has an important molding with a rounded vertical section projecting towards the axis of the pot and consequently reducing the

entrance section of it.

  More specifically, the upper flange caps the shell and is composed of an outer crimp band and an inner ring shaped in a rounded upper ring and an inner bead with omega section, extended downwards by crimping in the hollow of a small molding of the ferrule associated with a

  corresponding molding of the outer crimping tape.

  In fact, the bead or inner molding projects from about one third to half the height of the flange and that its top is at a distance from the top of the pot equivalent to the prominence of said bead

or molding.

  To be more specific, it has been found that

  interesting results were obtained by giving the fluff

  let or inner molding a projection of 40 to 50 mm.

  Solution to the problem, benefits and industrial result.

  With the device of the invention, we have

  At each turn of the loveur, the wick was placed under the bead and that, given the rotation of the pot, the friction of the wick against the bead pushed it downwards and piled up the coils of wick wrapped in hypocycloids. In practice, it has been found that a spinning pot according to the invention contained

  about 20% more material compared to a pot

  oitional. The invention will be better understood by means of

  the following description which gives a non-limiting example

  practical embodiment and which is illustrated by the drawing Joint.

  Description of an embodiment

  A spinning pot is composed of a ferrule

  cylindrical 1 reinforced bottom bottom (not shown

  tee) and a metal upper flange. This pot is intended to receive a wick of textile fiber 3 which is stacked hypocycloides 4, as seen in Figure 2. This stack is made by rotation of a loveur which distributes the wick 3 and by simultaneous rotation pot that rests on a turntable forming part of the textile machine. During this winding in which the wicks 3 stack in the form of a hypocyclo 4, it is constituted in the center of the pot, a chimney 5. At its entrance

  in the pot, the wick 3 rubs against the collar 2.

  What has just been described is widely known.

  The novelty of the invention lies in the fact of using precisely this friction of the wick 3 against the collar 2 to obtain a compression of the turns

  hypocycloidal 4 in order to increase pot capacity.

  To achieve this, the flange 2 comprises a large molding 6, with a rounded vertical section, projecting towards the axis of the pot. The profile of the molding 6 is clearly apparent in Figure i and especially in Figure 3. We see

  that this molding reduces the inlet section of the pot.

  More precisely, to obtain this molding 6, the collar 2 is formed with an outer crimping band 7 and an inner ring 8. The crown 8 has a rounded upper ring 9 which caps the top

  of the shell 1 and which has, roughly, a circular section.

  The upper band is extended inwards by the molding 6 or bead which has an omega section (in fact this omega is turned 900). On either side of the omega-shaped molding 6 are formed grooves 10 and 11 obtained by rolling and which crush the top of the shell 1 against the crimping strip 7. The lower end of the inner ring 8 ends even following a flare 12, also obtained by rolling, which constitutes a crimping in the hollow of a small molding 13 of the ferrule associated with a corresponding molding of the crimping tape

  7. The molding 13 is also obtained by rolling.

  The top 14 of the crimping tape 7 is also capped

by the Upper Ring 9.

  The protrusion "su of the molding or bead 6 is about one third to half the height" h "of the flange 2. The top 15 of the molding or bead

  6 is at a distance from the top of the pot equivalent to "s".

  It goes without saying that the forms of details, the raw materials and the various arrangements can vary without departing from the scope of the invention and that the essential of this consists in the presence of the molding or wadding 6 which has a suitable size in relation to the diameter of the wick 3 so that it can be pushed downward during the movement to relate said wick with the

rotating pot.
