(Cl. 223-60) This invention relates to an apparatus for to a pressing treatment, whilst at the same time treating and shaping hollow or tubular textile the articles are maintained for a suflicient period goods, and more particularly stockings, which, in contact with the pressing elements. for the purpose of carrying out the treatment and A further object is to provide anqapparatus of shaping, are mounted on moving forms, the said this kind which will not be unduly large'as com- 5 treatment including essentially a pressing oppared with the output obtained. eration.

An essential condition for the treatment on continuously moving forms and sub- 15 satisfactory operation of a machine of this known jecting the articles thus mounted to a pressing kind-is that the forms are moved intermittently. treatment by means of pressing elements, such During the pressing operation between the pairs as pairs of plates, which for the actual pressing of plates the forms require to be stationary, whilst operation are moved together with the said forms after the pressing plates have been lifted from through the machine. 20 the forms the latter are again advanced. In the preferred embodiment ofthis invention, Since machines -of this kind are normally comthe pressing plates are carried by two driving elebined with other treating apparatus, such as ments which each traverse the machine over enddrying chambers and the like, it follows that the less tracks and are symmetrically arranged on movement through the additional apparatus must opposite sides of the track followed by the forms.

These disadvantages are form with which they are to engage and the due solely to the intermittent movement of the plates are then pressed against the form. This 30 forms, arrangement is particularly advantageous when Machines have also been proposed for the treatthe articles being treated are made of fine fabric ment of stockings mounted on forms, wherein the such as artificial silk stockings, since it obviates forms are moved continuously and the stockings any strain on, and deformation of,- the fine artimounted thereon are subjected to a pressure ficial silk fabric of the stocking which may be set 35 treatment between pairs of rollers. In this type up even by the smallest movement on the part ofof apparatus the disadvantages arising from an the form in relation to the pressing plates. Likeintermittent movement of the forms are avoided, wisethe pressing plates when leaving the form but on the other hand there is a further disadtrack are first lifted evenly from the form and 40 vantage due to the nature of this type of appathen guided for a certain distance parallel to the 40 ratus. form before ultimately diverging for the return It has been found'in practice that the stockmovement to the initial point of treatment. Prefings or other articles whilst mounted on the forms erably for this purpose the plates are furnished require to be subjected to a pressure treatment at their rear, taken in relation to the direction of for a certain length of time in order to accommovement, with abutments which extend beyond '45 plish the requisite shaping and pressing of the the pressing surface. These abutments move in articles. In passing the forms having the arpairs on to a wedge provided at the outlet end ticles mounted thereon between rollers, the time of the apparatus and merge into a parallel guide of treatment during which the articles are in which causes the parallel movement of the plates contact with the rollers, that is to say, during in spaced relation to the forms as above de- 50 which a pressure is exerted on the fabric is obscribed. viously short. The drive for the moving forms preferably is It is the primary object of the present invention positively coupled with the drive for the plates. to provide means by which textile articles, such The plates are mounted on endless chains, the

as stockings, mounted on forms may be subjected path ofeach of which consists of two lengths as running parallel to each other, the one nearer the forms being shorter than the other, so that the chain sections on the parts of the tracks connecting the two lengths are inclined outwardly away from the form track. This arrangement is obtained by the special disposal of the guide wheels and the fixed guides for the endless chains. It has the object of ensuring under all circumstances that after the lifting of the pressing plates from the forms there will be no further contact with the articles on the forms when the pressing plates are deflected from their straight run through the machine.

The pressing plates are so mounted as to be capable of a rocking movement in relation to their supporting chains and also so as to be capable of a reciprocatory movement across the chains. This arrangement has the advantage of causing each pressing plate to be so adjusted in relation to the form with which it is engaged that during the pressing operation it acts evenly on the article, for example, the stocking, at all points.

Preferably each pressing plate is mounted on its supporting chain mid-way of its width, for example, by means of a pin and slot connection, flat springs being provided which bear against the marginal zones of the plate for the purpose of holding the plate resiliently in a certain neutral position. It is, of course, also possible to employ other constructions for the same purpose.

The invention is illustrated by way of example in the accompanying drawings, in which:--

Figure 1 is an elevational view of one embodi- 'ment of the machine according to the invention.

Figure 2 is a plan view of the apparatus shown in Figure 1, partly in section.

Figure 3 illustrates on enlarged scale the method of mounting a pressing plate on its supporting chain.

Figure 4 illustrates on enlarged scale and somewhat diagrammatically the outlet end of the apparatus.

Figure 5 illustrates on enlarged scale the operation which takes place at the leading-in end of the apparatus.

Figure 6 illustrates a machine embodying modified form of pressing plates.

Referring now to the drawings, there is provided on the base I of the apparatus a frame 2 composed of pillars and supports. In this frame there are arranged two gearwheels 3 and l which mesh with each other and are caused to rotate by a suitable drive (not shown). On the shafts of these gear wheels there are fixed sprocket wheels 5 and 6. The sprocket wheel 5 is connected by a driving chain 1 with a sprocket wheel 8, which is rigidly connected with a sprocket wheel 9, over which runs the chain l0 carrying the pressing plates. A similar arrangement is provided on the opposite side of the form'track. Similar reference characters have been employed to denote like parts.

The sprocket wheels 9 are: mounted on vertically disposed shafts H. The forms, which in this embodiment are shown as upright, are mounted on the chain l2 in any suitable manner, and the form track comprising the said chain l2 and the forms I! moves in the direction of the arrow P. I

For the purpose of illustration the forms are shown to consist of flat solid metal. They may, however, also be hollow and, if desired, heated either directly or indirectly in any known manner.

On the chains III, which are disposed symmetrically opposite to each other, there are 10- cated the pressing plates H. The particular method of mounting the pressing plates is illustrated by Figure 3. The pressing plate I4 is provided at its center with an abutment l5 having a slot l6. On the chain Hi there is situated a corresponding bearing member l1 having a pin l8 engaging in the slot IS. A flat spring H, which is bent about the free end of the abutment I5 and two pins 20 in the bearing member, bears with its two free ends against the edges of the plate H for the purpose of holding the latter resiliently in a, neutral or midposition. On either side of the form track there are situated guide faces 2|, along which the chains 10 move.

At the leading-in end of the apparatus, as shown in Figure 5, there is also provided a special guide 22 which lies substantially parallel to but spaced from the guide face 2| at this point. The pressing plates M are provided at or near their leading edges with outstanding lugs 40 having upstanding pins ll which, as the form is about to enter into its effective position, are engaged by the guide 22 to cause the pressing plate to swing round againstthe action of the spring I9 into a position in which it is parallel to the form track. Each presser plate travels for a short distance in this position parallel to the form track before it, as shown in the case of the presser plate on the right hand side of Figure 5, is pressed by its spring I9 against the form and accordingly against the article under treatment, for example, the stocking. I

The endless chains l0 are so mounted (by means of the disposition of the gear wheels 9 and the guides 2|) that the two parallel parts thereof are of unequal length, that part A (see Figures 2 and 5) which is disposed nearer the form track being shorter than the other part B and joining the same through an outwardly diverging part C. It will be apparent from Figure 5 that by reason of this arrangement the pressing plates are able to perform their turning movement at either end of the apparatus without entering into contact with the forms during this part of their movement.

The pressing plates are also provided at their upper ends with abutments 23. As shown in Figures 2 and 4, these abutments are situated at the rear of the pressing plates taken in relation to the direction of movement of the form track. At the outlet end of the machine there is provided a wedge member 24, which merges into a parallel guide 25. As the abutments 23 encounter the wedge member 24, the rear ends of the pressing plates are wedged apart, thereby maintaining the plates H in parallel relation to the forms l3. This arrangement has the advantage of causing the pressing plates I 4 to be lifted from the forms and guided for a certain distance parallel to the forms before they diverge outwardly by reason of the inclined chain section C, as illustrated in Figure 4.

As shown in Figure 6 the pressing plates ll may also be shaped in accordance with the forms, the foot portions 42, when the apparatus is to be used for treating stockings for example, then assuming a position within range ofthe preceding plate.

It will be understood that numerous embodiments of this invention are quite possible within the meaning of the above description and the annexed claims, so that the specific embodiments referred to in the above are intended merely to be illustrative and not in a limiting sense.
