D06f 71 /08; D06c 15/00 ABSTRACT OF THE DISCLOSURE This invention provides an apparatus for pressing knitwear goods. The apparatus includes a plurality of planar supports which move sequentially through at least three different stations for loading, pressing and unloading the said knitwear goods. Thin forms corresponding to the contours of the knitwear goods are placed on the said supports. As the supports carrying the forms pass through the pressing station, planar pressing plates located on either side of the supports move together to press the knitwear goods.

SUMMARY OF THE INVENTION The object of the present invention is to propose a pressing device which is particularly adapted for the pressing of knitwear and which is easily controllable and of simple operation, taking into account that knitwear to be pressed is usually fitted on appropriate forms on which the pressing operation is effected, thereby to ensure high efficiency in operation and good quality of the pressed knitwear.

To attain this object the present invention provides a device of the initially specified type, which comprises a plurality of separate supports for the goods to be pressed, which supports are radially outwardly inclined towards the service side and arranged in a circle for rotation about a common centre, a plurality of forms mounted in said supports and adapted to receive knitwear to be pressed, and a stationary pressing station including relatively approachable upper and lower pressing plates each inclined according to said supports, adapted to be lifted and lowered individually and adapted to be sequentially fed with the supports carrying the goods to be pressed.

Consequently, the invention provides a plurality of supports for the goods to be pressed which are arranged in a circle and for rotation about a common centre and to be sequentially indexed to a plurality of treatment stations at which such goods are applied to the supports, prepared for pressing, pressed, and removed from the supports after pressing, respectively. The radially outwardly inclined supports afford simple and effortless handling. High efficiency in operation is achieved due to the fact that a plurality of supports is provided, which enables different treatment of the goods on the individual supports to be effected at the same time.

The two pressing plates at the pressing stations are arranged at the same inclination as the supports and so that they can be lifted and lowered individually, thereby to ensure that the pressing plates will clear both sides of the goods after pressing. Heat and moisture thus can rapidly dissipate from both sides of the goods so that these will maintain the finish obtained.

BRIEF DESCRIPTION OF THE DRAWING An embodiment of the invention will now be described ice by way of example and with reference to the accompanying drawing, in which:

FIG. 1 is a schematic side elevational view of a pressing device constructed as a revolving unit according to the invention;

FIG. 2 is a schematic plan view of the device of FIG. 1, and

FIG. 3 is a part sectional view of a detail of the device of FIGS. 1 and 2.

DESCRIPTION OF SPECIFIC EMBODIMENTS Referring to the drawing, the pressing device proposed by the invention is particularly adapted to, and provided for, the pressing of knitwear. For pressing, knitwear is usually fitted on thin-walled forms 10 by which the goods are pressed into the desired shape. The forms 10 suitably may be of split construction. In the illustrated embodiment the form 10 comprises a body member 10a and two loosely attached arm members 10b, as shown in FIG. 2.

The pressing device proposed by the invention comprises a plurality of supports 11, 12, and 13, for the goods to be pressed. The supports 11, 12 and 13 are arranged for rotation about a common centre and include substantially trapezoidal frames 14 provided with a covering 15 of suitable textile fabric. The article to be pressed is placed with the form 10 on this covering 15 (FIG. 2). The frames 14 of the supports 11, 12 and 13 are secured to a triangular supporting strut frame 16 connected to a central revolving rim 17 mounted for rotation on stationarily supported rollers 18.

The revolving pressing device thus formed is intermittently rotatable by a motor 19 for sequentially indexing the supports 11, 12 and 13 into different treatment locations. A revolving rim 17 is mounted for rotational movement on rollers 18. The motor 19 drives the rim 17 through the use of any conventional driving means shown schematically and unnumbered.

The frames 14 and thus the supports 11, 12 and 13 are arranged at a radial outward inclination of preferably 15 degrees (FIGS. 1 and 3), which provides for easy and effortless handling. Particularly the arm and neck portions of the goods to be pressed can be easily dressed on the supports 11,12 and 13.

The mounting of the forms 10 in the pressing device is likewise designed for easy and effortless handling of the goods to be pressed. To this end the forms 10 are provided with preferably U-shaped holding frames 20 each including a web portion 21 insertable in snap mountings 22 on the supporting strut frame 16. Such snap mountings 22 comprise a leaf spring 23 fixed at one end and covering a groove 24 provided in a holding block 25 secured to the supporting strut frame 16, as shown in FIG. 3. Each of the struts of the supporting strut frame 16 is provided with two snap mountings 22 for securing one holding frame 20 of the form 10. To facilitate operation the snap mountings 22 are designed to permit pivotal movement of the holding frames 20 and thus of the forms 10.

The rotary pressing device proposed by the invention is provided with a stationary pressing station comprising two pressing plates 26 and 27 disposed respectively above and below the supports 11, 12 and 13. As shown in FIG. 1, the pressing plates 26 and 27 are arranged at the same inclination as the supports 11, 12 and 13. Moreover, each of the pressing plates 26, 27 is mounted to permit individual lifting and lowering thereof so that at the end of each pressing operation both pressing plates 26, 27 can be removed simultaneously from the supports 11, 12 and 13 and thus from both sides of the pressed goods on the latter, thereby to ensure rapid dissipation of heat and moisture. The pressing plates 26 and 27 are provided in a known manner with means for steaming the goods to be pressed and with steam extractor means. These means are operated in a known manner before, during and after the pressing operation. Especially for steaming prior to and after pressing the pressing plates 26 and 27 will be arrested temporarily at a distance of 10 mm. from each other. For fixing, the pressing plates then are completely moved away from each other so that air is allowed to get at the goods from all sides, hence also through the supports which are permeable to air.

The upper pressing plate 26 is secured to a swinging arm 28 anchored in the centre of the rotary pressing device. In this manner it is achieved that the pressing device is completely free outwardly, that is, also in the region of the pressing station.

In the region of the sector-shaped supports 11, 12 and 13 stationary guard bows 29 are provided to prevent the operators from stepping into the path of rotation of the pressing device.

The illustrated pressing device permits a plurality of operations to be effected at the same time. For example, while a pressing operation is effected on a first support, e.g. 12, it is possible, at the same time, to dress and prepare goods to be pressed on a second support, e.g. 11, following the first one in the direction of rotation, and to remove the pressed goods from a third support, e.g. 13.

The invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiment is therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
