up between the different pairs of rollers in one At an angle of about 35 ° to the horizontal. Bas towel would come from a washing device (of the kind described in US Pat. No. Kr. 3,526,106 shown) coming in the direction of the gate and would After rinsing in the device according to the invention, move on to a drying device o Bas towel is moved forward by the rotation of orphans 14 to 17

Between the uppermost W & lzsnpaas & i6, 22 and 17 »23 is a water sprayer 46 placed "from the clean." Rinse water is transferred to the top of the towel wandering between the pairs of rollers. This represents the final rinse of the towel, so clean Y / aseer must be used. Collecting troughs 47 are arranged below the two pairs of rollers and, while eioh Moving the towel up, the water that is on

The towel is sprayed, either carried upward clutch

and / the rollers 17 and 23 removed or it will flow downwards under the influence of gravity and duroh the Rollers 16 and 22 are removed ο In both cases the water removed by the rollers from the towel is collected in the troughs 47, the water collected in this way migrates then along the channels 32 and 33 which extend from the troughs 47 extend around the towel strip passing through between the rollers 15, 21 and 16, 22 and then becomes from these channels poured onto the towel strip to rinse it. The channels are at a very low level Angle inclined to the horizontal to ensure uci that no water collects in troughs 47. Bas from channels 32 and 33 on the towel incoming water causes deooen last rinsing with

again some water is transported up, bit to the rollers 16 and 22 * while an endex amount of water flows near the bottom and through the rollers 15 and. The water removed on the upper pair of rollers 16, 22 is of course fed back into the circuit, while the water removed on the lower rollers 15, 21 is collected through a further trough 47 and used to move the towel between the rollers , 19 and 15, 21 to rinse. The process here is the same as just described, and finally the water removed on rollers 14 and 19 is collected in the lowest 'frog 47 and passed through channels 48 and 49 to pre-rinse the hand towel 18 before the first set of rollers achieved »The portion of this pre-rinse water that is transported upwards is fed back into the circuit, while the water flowing down under the influence of gravity moves further down the towel and reaches the washing device, where it is used Washing the dirty towels is used ₀

It can therefore be seen that the handtuoh is flushed four times, which is achieved in a very economical way, because Irish water is only added in the last rinse stage will. The pure water supplied by the spray device 46 is only used for this final rinse, while the water is used for the previous rinses, at least for the next one Rinse has already been used, so the water used for the pre-rinse is already quite dirty. Duroh the arrangement inclined at an angle of 35 ° the device ensures that the either duxoh the spray device 46 or through the various

Channels on the towel, distributed water, so that part of the water runs downwards hu lower set of rollers, while another of the water is carried through the towel to a higher bolionsate in this path If the angle of inclination of the device is too steep, all the water would run down and there would be no separate soaking effect from the water carried up by the towel, and the water would also pass through the device much faster otoon be transported, which for example means that by the troughs 32 and 33 on the towel total water again lssen to the W & yacl 16 and 22 would then be constantly recurring collected by the same B ^s? i% e. Bas would suggest that the lower spill stages would ksift water e ^ iwiltea and that moreover the water transferred by the spray device would possibly cause an overflow of the troughs 32 and 33, so that the water would run down axa frame 11 without any Exert rinsing action. The device is also economical in that the pre-rinse water runs directly into the washing machine by running down the towel, instead of having to be collected and recirculated as was the case with known devices, in fact also for washing in earlier devices only rinse water has been used. It will be understood that the 35 ° angle is not invariable, but where the towel is being passed through the device at high speed the angle should be steeper and where the towel is being passed at slower speed the angle should be shallower
