My invention refers to a machine for dryin fabric and similar, lengthy web material by means of a single drying drum and brings about certain advantages over horizontal or vertical machines of the multi-drum type by providing an important economy in the consumption of steam.
More particularly, the drying machine according to the present invention is characterized by the combination of a heated drying drum performing a rotary movement, with a series of nozzles for blowing hot air and arranged concentrically with respect to said drum, the openings of said nozzles being provided at a small distance from the periphery of the drum, and means for causing the material to be dried to move into contacting relationship with the drum; a compartment or casing being further provided to enclose said drum, said nozzles and other operative parts of the drier.
Preferably the air blowing nozzles are of the extensible or telescopic type as disclosed in my prior French Patent No. 856,315 whereby it is possible to modify the nozzle lengths and to arrange the same in accordance with the width of the fabric undergoing treatment.
By way of example the accompanying drawings show a preferred form of a drier with a single drum executed in accordance with my invention.
Fig. l is an elevational view of the drying machine, the front wall of the compartment being removed to allow the inside to be seen.
Fig. 2 is a vertical cross sectional view.
In the drawings, I designates the drum formed by a steam heated cylinder; 2 and 3 designate the admission and exhaust pipes for the heating steam; 4 designates the pulley controlling the drum and actuated by the electric motor 5.
A heat insulating compartment 6 encloses cylinder I and the fabric I passes into said compartment through a suitable slot to engage the surface of the drum or cylinder I and moves thereafter out of the compartment through another slot. A selvage guider is shown at 8 while 9, I0, H, I2 designate the guide rollers for the fabric to lead the same at the inlet and at the outlet of the machine. Numeral I3 designates a mechanical folding arrangement.
Round the drum I and coaxially therewith are grouped nozzles I4 placed to extend in the direction of the width of the fabric 7, the air blowing ends of said nozzles being open in proximity with the outer surface of the fabric which remains with its inner surface in contact with the drum and receives the heat of the latter through direct contact while it is submitted simultaneously to the action of the hot air forced through the ends of the nozzles.
I5 designates a blowing fan, and I6 an aerothermic device for heating the air as it enters the nozzles, said device being arranged, for instance, coaxially with or substantially encompassing the nozzles and the drum.
As disclosed hereinabove, the nozzles I 4 may be of the telescopic type. As shown in Fig. 2, [4a illustrates the central and circular-shaped stationary conduit or part, the length of which corresponds to the minimum width of the fabrics or approximately one half of the width of said drum, while Mb designates each of the lateral sliding conduits or portions carrying nozzles which in the outermost or extreme positions correspond to the total width of the drum (see Fig. 2)
The air laden with moisture is removed from the compartment 6 through a chimney (not illustrated) which includes an adjusting damper.
Obviously it is possible without widening the scope of the invention to imagine various modifications and improvements to the above apparatus.
Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent is:
A machine for drying lengthy web material, comprising a rotary, hollow drum body adapted for the passage of steam therethrough, whereby the outer circumference of said drum body is heated from therewithin, a plurality of nozzles arranged in side by side relation to each other on the outside of and coaxially with said drum 'body, said nozzles being provided with respective discharge ends spaced from the circumference of said drum body, stationary circular-shaped conduit means including heating means substantial- 1y encompassing said nozzles and said drum body, whereby hot air is supplied to said nozzles for impingement on the outer surface of said web material when the latter is in contact with said drum circumference, roller means adjacent said drum body for guiding the inner surface of said 3 web material in contact with substantiall the entire circumference of said drum body and facilitating discharge of said web material from said drum body, telescoping conduit means extending to at least one side of said circular-shaped con- 5 duit means and telescoping with respect to said circular conduit means for adjusting the position of said nozzles with respect to the width of said drum body, and a heat insulating housing surrounding said drum and supporting said roller 10 means.
