The pipe sections 26 in contact are laterally held in place by the sections 29 of the side walls 23 and at the longitudinal ends of the device by two closure plates 50. At the longitudinal ends, there are also jumps in the base plate, of which the front projection shown

The © pipe section © 26 are τοπ one? rectangular / thin flexible bsw ₉ "elastic cover plate 33 covers ₉ are preferably bestehtο from a translucent material very suitable sum example folymetbylmetaerylat or Po! vinyl chloride. The plate is so long that its ends overlap the upper lands of the end plates 30; and it is just as wide as the distance between the sections 29 of the two. Side walls 25 *

^A n the two longitudinal edges of the cover plate 33 are below the bearing surfaces 21, two τγογ upward "jumping bead fiandverstärkungen 3 ^ · provided by quite * = angular cross-section as Druckelement® ₉ are bevelled at their front ends _s so that the glass plates 35 easily between Strips 22 and the edge reinforcements 3'4 can be inserted "" After inserting any number of plates, the bellows 25 is inflated with the ball 9 · =

Then the pulp-shaped sorbent is applied in a known manner with the coating device 36. When all the glass plates 35 are provided with a coating, the air is let out of the bellows 25 take the plates 35 ° In addition, there is the possibility _{8 to} pull out the entire cover plate 33 ₉ whereby the glass plates 35 & ηϊ of the cover plate 33 lie like on a conveyor belt, so that the over-eye can be dried outside the plate receiving device ο

If during the coating will swamp some of the pulp between the glass plates 35 ₈ which often can not be avoided is "ao sor ^ t the cover plate 33 for being contaminated that the pipe sections 2S and the bellows 25 nieht" The eand-yerstärkungen 3 ^ · act

In the figures 2 ₉ 3 and 4 EI: ae further execution = - form of the inventive device shown Here too, a rectangular base plate see 40 laid ", but the Seitenwänäe 47 are portions of two mounted on the two Längskanteh the base plate side portions 41, the both as figure 4 showed a rectangular rinnenförmigeas upwardly open cross have = cut "Each side member 41 is at its front = the end in a box 42 above ₉ which is fixed to the side of the base plate 40 and slightly narrower than the side part 41 ₀ Short inclined front panels 45 are arranged on both fasteners 42 between the side walls 47 and the inner walls 46 of the side parts 41 and close off the front sides of the side parts 41 _o

At the rear end of the side parts 41 are connected by a likewise rinnenformiges rope 53 ^ which open side the side parts 41 facing ₉ and which is fixed on the base plate 40 "in that of the side parts 41 and the part 53 formed U-shaped channel» of the Ber.eieh the side parts 41 is open at the top, an inflatable, preferably from

Rubber-made tube 55s which forms the elastic pressure member "In the area of the box 42 lie the two ends of the tube 55 ₉ of which one end © is connected to a tube 43 and the other end of which is a drain valve 44

From Figure 4 it can be seen “that the side walls 4? are higher than the inner walls 46 and have inwardly angled, horizontal strips 48. The lower surfaces of the strips 48 are flat and lie in a common plane 5 they form. Contact surfaces 5O ₈ against which the transverse edges of the glass plates 52 are pressed »

For this purpose, a number of pressure elements a with flat surfaces are provided above the hose 35 in the area of the side parts 41, which are shown as plates 56 for the sake of simplicity Walls 46 and 4? of the side parts 41 fitted so that they 3 ¹ ? are pressed upwards against the lower surfaces of the ¹ strips 48 ο

In use of the device, the glass plates 52 to be coated are successively between the plant = surfaces 50 and the upper edges of the inner walls 46 towards the rearward end of the device

Then the valve 44 is closed, if it is open, and air is blown into the valve 55 via the pipe connection with a pump so that it expands and the platelets 56 close up against the lower surfaces The glass plate 52 presses "The plates 56 are" less than half as wide as the glass plates 52 $ so that each glass plate is pressed evenly by at least three plates 56. Bio coating and the removal of the glass plates then takes place in the above If "manner described porridge awischen the glass plates seep 52, he dropped onto the base plate 40 and can be wiped off easily ₀
