• the device shown in these figures 1 to 7 operates as follows, for example:
• doormat 18 is placed on the lower support plate 16 and one end of the same through the slot 17 m the area of the lower conveyor roller 20 led. From this Forderwalze 20, the doormat 18 is assisted by the pinch rollers 22 retracted and moved along the contact surface 34 upwards. Once the doormat 18 in Area of the nozzle head 24 are directed from the at least one nozzle 26 for cleaning jets directed to the mat 18 to clean them and stones, dust, particulate matter and the like. to free. Just above the (water) nozzle 26 at least one nozzle 28 is provided on the nozzle head 24, from which a jet (possibly heated) air exits to dry the doormat 18 again.
• a jet possibly heated
• the nozzle head 24 is reciprocated to carry out the cleaning work and the drying work transversely to the traveling direction of the floor mat 18 to detect the entire width of the floor mat 18.
• the stroke of the nozzle head 24 can be matched transversely to the direction of travel of the floor mat 18 to the width of the floor mat 18 detected, for example, by sensors.
• the front end of the doormat 18 to be cleaned so its already cleaned area detected by the upper transport roller 30 and supported by the pinch rollers 32 associated with this Forderwalze 30, moved out of the upper slot 36 of the housing and passes (FIGS. 4 to 7) onto the upper guide plate 38 and is stored there again rolled up. From there, the cleaned doormat 18 can be removed and placed again at the designated location, for example in the area of the entrance to a building.
• Fig. 8 shows an embodiment of an inventive device is shown, in which instead of the transport rollers 20, 30 and pinch rollers 22, 32 pairs 40, 42 of mutually opposite Forderketten 44, 46 (caterpillar tracks) are provided. It is such that in each case a conveyor chain 44 of each pair 40, 42 is mounted by Forderketten in frame 10 and the other Forderketten 46 in the frame 10 are transversely adjustable, so that the distance of the Forderketten 44, 46 from each other to the thickness of the cleaned Flat structure (doormat 18) can be adjusted.
