Claims priority, application Belgium March 6, 1950 6 Claims. (Cl. 242-118) Conical or cylindrical perforated dye tubes made of metal or specially impregnated paper adapted for winding textile threads, intended for bleaching, dyeing and the like yarnsin package are used since a long time.

Nowadays, the thread spools or cheese are executed in such a manner that fthe two ends o the `tube remain free for instance over about l cm., because in order to avoid the risk of some threads projecting beyond the base of the conical tube and being damaged during subsequent handling.

When it is desired to bleach or dye conical cheeses they are fitted over a carrier of the treating machine. Such carriers include a three or four rib spindle or a perforated dye tube allowing the passage of liquids through the superposed package system thus formed. This cheese system or upright column communicates with the openings provided in the double bottom of the circulation machine.

It is, however, necessary to insert between the successive conical cheeses an intermediary spacer or inset acting as a packing between said cheese. 'Ihis spacer is for instance a round corrugated plate provided in its center with an opening adapted to be fitted on the spindle in the same manner as the cheeses over the machine carrier. The corrugations of the inset washer match through one surface the small diameter of a conical dye tube and through its outer surface the larger diameter of such a tube. Without such spacers, the Wider end of one conical dye tube would engage the cotton threads on the next and risk cutting the latter or staining them through such a localized pressure.

The use of insets leads, however, to a supplementary operation and implies the drawback that the workman or the apprentice may inadvertently lay said insets upside down. On the other hand. as the ends of said conical tubes may become damaged through Wear, this results also in a lack of iluidtightness between the tubes and the insets.

The present invention has for its object to make such insets unnecessary while avoiding the above mentioned drawbacks. To this end, the larger base of the perforated conical type is provided With an outer thicker sectional ange which allows winding the treads up to the extreme end of the tube without any risk of the threads projecting beyond the base of the perforated tube.

This thickened wall section or ange may be constituted by a ring welded over the outside of the cone along the periphery o its larger base but it could also be made through other means e. g. by folding the end of the cone outwardly.

A further important feature consists in providing, in addition to the outer extra thickness of the tube, an inner ring-shaped flange. which may be shaped through stamping to form a ring engaging' the outwardly folded end oi the perforated conical dye tube.

Accompanying drawings show by way of example .and by no means in a limiting sense how the invention may be practically executed.

In said drawings,

Fig. l is a perspective View of a conical dye tube according to our invention.

Figs. 2 and 3 are a perspective view and a partly torn-01T sectional View of a modification.

Fig. i diagrammatically shows two supcrposed improved cones.

Fig. 5 relates to a further modification.

Fig. 6 illustrates means for winding thread on the improved conical tubes.

In Fig. 1, l designates a perforated metal body forming a conical dye tube that is provided, according to the invention, with a flange, ring or extra thickness 2 along its lower edge defining the larger base of the cone.

This ange may be constituted by a ring welded to the edge of the cone although any other suitable means may be used. This ange or extra thickness thus provides means for winding the thread down to the lower limit of the perforated body of the conical tube without any risk of some threads sliding oir the cone and it is, therefore, possible to superpose the conical cheeses over one another in the treating machine Without an inset being required between them.

In the embodiment disclosed in ligs. 2 and 3, fthe lower edge 'l of the tube I l is bent outwardly and is provided with a flange 2 that is tted over the bent edge through stamping so as to form the desired extra thickness.

As illustrated in the drawing, the outer ange 2 may be in one with an inner ring or annulus 8 forming an annular ilange along the edge of the conical tube.

Said latter ring 8 should have preferably a breadth of live to ten mm. but it is necessary in all cases that it allow the tubular cones to fit, to a suihcient extent, inside one another when the spools or cheese are superposed inside the treating machine. Furthermore, this ring 8 is provided advantageously with small apertures 9, the number of which is for instance six, said openings being adapted to further the passage.

upper edge of the perforated 'conical rtube inwardly, as shown at ll in Fig. 5, in ordertovr prevent the formation of a cuttingedge and to increase the resistance of the Stube.

By reason of the presence ofithelinnerL-.at .ring or annulus 8, the larger end of the cone extends through a much lesser length over the end of the underlying cone. lesser risk of obtaining undyed partsand .there is also a lesser deformation of the upper end l'.oi the cheese on which an overlying cone rests directly and uniformly while a more intimate contact is provided between the superposed cheese positioned f inside the` machine in :column formation.

Furthermore, .the resistance of Lthemetal conical tubes is `increased .through vthis rvstructure which :forms an important f advantage, f especially if` one considers that such articles are oftentaken little fcare of and easlyallowed tozdrop Lto 'the ground.

Finally, the outer ilangefatthe larger end of the .conical tube by no means impedes thereplacement of the-latter by a'wooden-or cardboard cone, once -the package vhas vbeen dried, `before delivering the dried package lto the customer, when themetal conesfare` once-more, takeninto the operating cycle.

When it is desired -to wind yarn over such perforatedconical tubes, there'is positionedinside thev cone a mandrel of lwood or the like suit- Vable material made of two parts f3 land yIl. -as
