Description
Filed May 24, 1933 LNVGN TOR Patented Aug. 4, 1936 UNITED STATES CARDING MACHINE Narciso Serra, Cornella (Barcelona), Spain, as-
signor to Compafiia A116 Spain nima Static, Barcelona,
Application May 24, 1933, Serial No. 672,705 In Spain August 18, 1932 3 Claims. (01. 19-98) The present invention relates to an improvement in carding machines and its object is to provide means for preventing the fibres and foreign bodies from collecting in the covering or carding of the main cylinder of such machines.
It is known that in carding machines for the preparation of textile fibres before spinning, textile fibres and foreign bodies collect between the points of the covering or carding of the main cylinder while the machine is working. These fibres and foreign bodies collect so rapidly and in such quantities that it is necessary to clean the main cylinder very frequently. This operation is at present effected either by means of rollers or hand wheels or by a current of air of suitable intensity and direction.
These methods of operation are open to many practical objections one of which is that they are not suitable for the object in View. Moreover, these systems consume energy and produce dust and require special care to ensure their normal and good working, since any neglect may result in very serious damage to the covering or carding of the cylinder.
These objections are removed by the improve- ;nent forming the subject of the present invenion.
This improvement resides in providing means which consume no energy, are subjected to no wear and require no maintenance or lubrication. Moreover, as no dust is produced, this improvement is not detrimental to the health of the operative in charge of the machine in question.
This device is also extremely simple and cheap to construct, so that it can be fitted to all known types of carding machines in a very simple manner and at very little cost. Finally, it costs nothing to maintain.
Moreover, the carding machine to which the improvement forming the subject of the present invention is fitted gives working advantages. One of these advantages consists in a considerably increased production with an improvement in the quality of the latter, while a perfect uniformity is obtained in view of the fact that the cylinder is at all times completely clean. For this same reason the Waste from the machine is considerably reduced since no fibre adheres to the covering or carding of the cylinder. At the same time, the covering or carding has a longer life; the ribbon for the cleaning devices is saved, and the current of air produced around the cylinder when it revolves is opposed, thereby reducing the amount of fibre detached, a fact which is proved by the small quantity of fluff that is formed beneath the comb.
The essential feature of the improvement in question consists in the fact that one or more frames of suitable size, made of a material which is preferably a bad conductor of electricity, are arranged in the transverse direction of the card and at a suitable point of the latter. This frame which follows the contour of the cylinder is covered with a pad of cloth, plush, silk, wool, cotton, rubber or bristle, and in general with any other analogous material. This device is placed at a suitable distance from the points of the metallic covering or carding of the main cylinder, and the whole operation takes place as though the said points become electrified and with them the textile fibres, which have a tendency to remain held in the extremity of the points as if they were pushed out by the pins of the covering or carding.
All details which do not relate to the essential feature of the device according to the invention may be varied; the form of construction, the pad which is the basis of the improvement and the frame which carries the pad; and also the manner in which the device is installed and the nature of the materials covering the frames. The said frame will be made of iron, wood, fibre, white metal or other material. With regard to the material covering the frames, the varieties that may be employed have already been indicated. This arrangement may, if desired, be insulated electrically from the machine and any means maybe provided, if it is thought necessary, for regulating its distance from the cylinder.
The position it occupies with respect to the cylinder will be that which is found most suitable; either below the comb, or above it, or at any other convenient position.
The size of the pad will be that which is found convenient, although practice has shown that if this pad has a width equal to 1/22 of the circumference of the drum, it is already sufiicient for the object in view. Naturally, this width will depend upon the kind of material covering the plates.
In order to make the invention more clear, a drawing is attached in which one embodiment of the said improvement is indicated diagrammatically.
In the single figure of this drawing, l is a part of the main cylinder, 2 a corresponding comb, 3 the plate which is the device effecting the improvement in question; 4 is the frame carrying the pad, and 5 the material covering the frames.
As already stated, in practice the device may vary and the type of machine to which it is fitted may also vary.
In general, any modifications may be made which do not alter the essential nature of the invention.
What I claim is:
1. The improvement in carding machines comprising a carding cylinder, consisting in mounting in spaced relation with said cylinder a plate composed of a frame which is preferably a bad conductor of electricity and covered with:adi-- electric material such as a textile fabric, the said plate being curved and arranged concentrically with said cylinder.
:the said plate being curved and arranged concentrically with the said cylinder, the plate being made of a material which is a bad conductor of electricity and covered with a di-electric material.
NARCISO SERRA.
