The invention relates to a fabric coupling machine and, more particularly, to a machine suitable for. the coupling from a fabric to a reinforcement intermediate lining, preferably to be carried out by a collar and its intermediate reinforcing material.

V.'ie known it is necessary in the manufacture of shirt collars and collars for garments in general the base fabric a rigid interlining material used for reinforcement, preferably consisting of hemp base material or similar canvas, assign.

The above-mentioned assignment has so far been achieved by using machines provided with heated metal plates where the fabric and the hemp canvas were printed after the latter with a thermofusible resin had been coated.

The mentioned heat treatment on the heated metal plates however, it has several disadvantages. Indeed, for example, the coupled fabric obtained is very often excessively large

109885/1187

by the polymerisation of those attached to the reinforcement fabric Resin layer resulting stiffness, mainly because the work is carried out at temperatures that are too high. On the other hand, however, nan when using lower temperatures on the above-mentioned conventional lines, unsuitably coupled fabrics, which can easily detach from each other.

The disadvantages described above can practically not be eliminated because the conventional. Machines do not insure careful control of the heated metal plates. The above-mentioned temperature is not spread further over the various portions of the surface of the nen Uetallplatten evenly.

iin v / eitexer the disadvantage that occurs with the conventional glass liners is that here the metal plates are subject to deformation as a result of the higher temperatures and pressures that they are subjected to heat treatment. For this reason it is not possible to use the referred to as herkömuliehen machines towards each other sufficiently increased pressures to be exerted on the coupling tissue. In addition, it is practically impossible to determine the values of the Set the pressure to which each gear to be coupled or each collar to be coupled is subjected.

Accordingly, the aim of this invention is to use a fabric dome aqhaffen that none of the aforementioned tile parts

10988 5/1167

having.

Another purpose of this invention is to provide a tissue coupling machine that allows both the pressure values and the temperature values to be carefully adjusted and to make the tissues evenly wet according to which whose specific properties are generally subjected should.

These and other purposes of the invention will become apparent from the following detailed description The invention is achieved by using a fabric coupling machine, consisting essentially of: two together working conveyor belts, between which those to be coupled Tissues are printed and fed to the various stages of treatment, one from a source of infrared X-rays existing heating medium and a V / arm air flow, two Pressure rollers on which the said conveyor belts slide, two drive rollers for the said conveyor belts and one coolant. -

The machine according to the invention therefore allows the coupling of fabrics and especially of collars to be effected continuously, whereby the fabrics themselves are held between two endless pieces of mushroom, the sliding speed of which can be appropriately varied within an incoming value gap.

109885/1167

In addition, the heat supply 'is to be treated Tissues and to the adhesive layer enclosed between them by the simultaneous action of the infrared X-rays and insured by the warm air attacking the reinforcement fabric from below. The said warm air comes out at the ends a set of tubes immersed in heating fluid over a sufficiently long cut.

Finally, the machine according to the invention allows the after heat treatment, to subject the coupled fabric to a pressure effect by means of one or more pairs of medium rollers, whose pressure can be varied and adjusted continuously.

It is therefore obvious that in the inventive ! .machine all physical quantities for coupling one Fabric to a reinforcement interlining in general can be used, whereby they are precisely controlled and adjusted independently of each other.

Zs is therefore possible, the drive speed and / or the To change the heating temperature and / or the pressure value depending on the type of tissue to be treated, in order to achieve the best coupling between the tissues themselves.

These and other features of the function and construction of the IIa machine according to the invention can be seen in the following description with reference to the in the at ~ ef i ". - : .y. \ Drawings v." j egg given fi gar en oesner ej '^ ünuea. ·,.: Soaps:

SAD ORIGINAL

The body of the Rolir itself is at the same temperature as the heating fluid.

JDa part of the exiting through the holes (48) of the box (50) Warm air is deflected as a result of the impact against the carpet and irc with regard to the poor thermal conductivity of the fabrics and the adhesive layer inserted in between, the latter does not could be heated evenly, so is the invention i.-as chine equipped with a source of infrared X-rays, which is denoted by (53) in the drawings. The said source of infrared X-rays is in turn within one on the hot air generator (50) on the same and contained within the band (45) arranged box »Inside the band (44) immediately after the pressure rollers (36) and (37) on its downward sloping portion a fan (54) admitting cooling air is arranged. This fan has such a sufficient width that the outflowing air is allowed to hit the entire portion of the carpet sliding on it.

The function of the machine according to the invention is very easy to understand the the continuous coupling of G-eweaving and in particular from linings with reinforcement lining Collar insured, in which all phases are controlled and can be adjusted.

1098Ü5 / J1Ö7

The Jetriebsmethode of the machine according to the invention sees the the following operations: the coupling of the tissue to be treated to one. Hemp base or on a storage layer, the latter being provided with a layer of suitable quality, then introducing the double layer thus obtained between the carpets (44) and (45) and the automatic start of the continuous coupling process.

As can be seen from the figures, the band (44) has a section that is not coupled to the upper band (45), and this ULi to arrange the tissues before tying the two together cooperating ribbons (44) and (45) are printed.

The fabric coupled to the hemp base or bearing layer is then inserted between the two belts of the machine and fed to the box (50), wherein it is supplied by a V / arm air flow has occurred.

At the same time, the radiator arranged on the upper part and on the box (50) compensates for any infrared rays in between The temperature difference between the two layers to be coupled to one another consists of the heat acting on the layers is broadcast even over the carpet (45).

The fabrics are then between the pressure rollers (36) and (37) taken after being at the most suitable temperature have been heated so that the adhesive layer between them performs the best bonding.

10 9 8 8 5/1167

The fabric coupling machine according to the invention can also one or more pairs of opposite ones on the base plate (1) fixed and preceding the pair of rollers (36) and (37) rollers (55), (56) and (57). The couples mentioned Roles have the task of promoting the coupling of the treated tissue.

By sliding between the inclined portions of the bands (44) and (45) then the coupled and glued together ground Tissue by a flow of cooling air from the fan (54) encountered the one between the said ligaments inserted adhesive layer solidifies.

The process mentioned and that of the belts on their end portions assumed inclination are very important when coupling the collar to the reinforcement fabric.

Indeed, the glue layer would be at the exit of the machine If not completely cooled, the collars would have a tendency to bend as this would cause a calendering effect were subjected.

To avoid such bending, make the last cut of the tape sloped downward to compensate for any possible opposing bend.

When making collars, it also allows those made of rubber or Teflon, the surface of the two rollers (36) and (37) covering layer, one on the entire surface

109 885/1167

the collar itself exert almost even pressure, i.e.

both with the portions, where the collar consists of two layers as well as with the portions, where the collar consists of three layers, which leads to regularity and evenness contributes to its structure.

Finally, it should be emphasized here that the machine according to the invention is equipped with a table (58) which serves to ^{control the ZLU 1} and to set all the physical quantities that are of interest to the tissue coupling work.

Any degradation or polymerisation of the adhesive layer is therefore excluded.

In the event of such circumstances occurring, there would be negative consequences on the quality of the treated tissue, such as the complete waterproofing, or an excessive stiff hex the same, affect.

The fabric coupling machine according to the present invention also allows the fabric and the interlining to be coupled together because of the heating of the adhesive layer and the pressure on the fabric are adjusted to suit the type of fabric used and the adhesive turn out most suitable.

From the foregoing as well as from the various in the, The figures reproduced in the accompanying drawings clearly show that the fabric coupling machine according to this invention

109885/1167

is characterized by better function and practical use.

It goes without saying that several variants and changes to the shape, construction and arrangement are accepted the machine according to the invention in their implementation can be introduced without in any way departing from the scope of protection of the invention itself.
