MACHINE FORrIDRESSING OB FINISHING SILK STUIFS.

Application filed June 12, 1914. Serial No. 844,820.

'1 '0 all whom it may concern:

Be it known that I, EMIL SCHNEEBELI, a citizen of the Republic of Switzerland, residing at Afl'oltern-on-the-Albis, in the Canton of Zurich, Republic of Switzerland, have invented certain new and useful lmprovements in Machines for Dressing or Finishing Silk Stuii's; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention has for its object to provide an improved machine for'dressing or finishing silk stuffs which machine preserves the freshness, the feel and the luster or gloss of the fabrics treated, shortens the time required for the finishing process, and further renders possible the employment of different methods of treatment. For the purpose of attaining this object the fabric is caused to pass through two superposed devices for spraying two different compositions on the fabric, which latter then passes through a drying box, in which its two sides are exposed to the drying action of a current of air flowing in a direction opposite to that of the travel of the fabric, and finally during the same travel of the fabric through the machine, the said fabric passes through the finishing elements, such as breaking rollers and calenders.

The separate devices which the improved dressing or finishing machine comprises, such as the rollers and the nozzles for applying the dressing or the like, the drying box, the breaking rollers and the calender rollers, are of the usual design commonly adopted in the art. Whereas, however, it was necessary hitherto that the fabric should traverse several machines, for the purpose of receiving-a complete finish, the fabric according to this invention need traverse the improved machine, in which the separate devices. are arranged and combined in a suitable manner, only once for the purpose of receiving a complete finish. By employing the improved machine it is therefore possible to efiect a considerable saving in for the finishing pr0cess,.the working expenses, the attendance and the space required by the machine. As the fabric need Specification of Letters Patent.

pass through the machine only once'fthe same retains its freshness, its feel and its I or for moistening and calendering. The

superposing of the spraying devices renders possible to spray simultaneously different dressing compositions on the fabric, which compositions cannot be mixed together, the application of which, however, is necessary for insuring a perfect finish. By means of the current of drying air accurately following the zigzag course taken by the fabric to be dried, but moving in opposite direc-' tion thereto, and uniformly passing over the two sides of the fabric, a drying effect of any desired degree may be obtained, and thus the fabric may be allowed to issue from the drying box at any desired rate which is required by the succeeding calender. This effect cannot be obtained with the existing drying contrivances working with or without the use of the counter-current principle.

The improved machine may be employed Further the dressing composition may be applied without artificial heating and cold air may also be used for drying.

One form of carrying the invention into effect is shown diagrammatically in the accompanying drawing, by way of example.

In carrying the invention into effect as shown in the drawing, the fabric 2 passes from an unwinding/roller 1 over a supporting roller 3, and over a wire netting, which is not shown in the drawing and which serves for preventing the fabric, when torn, from dropping down into the gear, to a guide roiler 4, at the opposite end of the machine. At this roller 4, the direction of travel of the fabric web is changed from horizontal to vertical. In this vertical direction of travel the fabric traverses two 'sprayingchambers 5- and 6, in-which the dressing composition is sucked up in a known manner by spraying nozzles 7 and 8, and is applied to the fabric 2, The object of these two spraying chambers is to enable one to apply to the fabric two different compositions which cannot be used togetherin one solution, and which are necessary for imparting certain properties to the fabric. From the spraying chambers, the fabric passes over a guide roller 9 into a drying chamber 12 of ordinary design, and provided with partitions or baffles 10 and 11,; in which drying chamber a considerable length of the fabric is exposed to the action of a current of air moving in counter-direction to the travel of the fabric and heatedto suit the particular requirements of each case. Of the guide rollers lid-23, the roller 14 is connected to the counter shaft 27 by means of a belt drive 24, 25, 26, which counter shaft 27 is driven. from the shaft 28.

Into the right handend of thedrying chamber 12 there opens a pipe 29 through which hot air to be used for drying is supplied, which air leaves the drying chamber at the opposite end through a pipe' 30.

Owing to thefact that the fabric traversing the drying chamber encounters a hot current of air moving in-the opposite direction to the travel of the fabric, a rapid drying is the result. The current of drying air accurately following the zigzag shaped course taken by the fabric\to be dried, but moving in an opposite direction thereto and uniformly passing over both sides of the fabric,

.renders-possibleiany desired degree of drymg, so thatthe fabric may be allowed to leave the drying box at any desired speed which may be required by the succeeding calenden From the. drying chamber, the

fabric passes over a. guide roller 31 to the roller 33 which is driven from the roller 14 by means ofLa-belt32, and fromthere to a 45 esign,.-'.which latter may be moved if reair' of-breaking rollers 34, 35of ordinary quired. Thereafter'the fabric 2 passes over a guide roller 36 to two calender rollers '37, 38, which are of usual design and of which the upper roller is pressed against the lower roller by the action of its own weight and the pressure exerted by the adjustable weight 39, the said roller, however, may be relieved of .the pressure exerted by the weight 39, in a known manner. by means of the hand operated lever 40,-t he cam 41,

and intermediate connecting rods. From the calender rollers which impart to the fabric any desired degree of luster or gloss, the fabric passes over aknown drawing roller 44 mounted on levers 42 and moved upward by a weight 43, and fromthereto a Winding up roller 46, driven by" means of belts 45-, from the shaft 27, and arranged above the unwinding roller 1. If necessary the fabric, before being wound up, may be passed over a second pair of breaking rollers 47,48.

If the fabric is only to be moistened, it is allowed to pass from the guide roller 9 over five guide rollers 49, 50, 51, 52 and 48 to I the drawing roller 44, thus by-passing the drying chamber 12.

The calender rollers are driven by a toothed gear wheel train 53, 54,, 55, 56 and 57. 1

If required, the fabric may be sprayed with dressing on both sides, for which purpose two spraying nozzles are arranged. in

each chamber 5 and 6. Further the fabric,

before entering the spraying chambers 5 and 6, may pass over rollers 58, 59 and 60, and

be provided with dressing liquor by means,

of a roller 61 or by means of brushes.
