directly on the mill floor if necessary also the turn rolls 7 u2032 7 u2033 can be rotated by means of an operating switch of the turn rolls the operating switch being arranged in connection with the maintenance bridge in fig3 the extraction device 1 u2032 is shown also in a standing position in which case the device 1 u2032 is turned out from the inside of the dryer in the example of the figure the swinging arm 16 u2032 of the extraction device 1 u2032 is in its standing position locked in an essentially vertical position whereby the maintenance platform 2 can be shifted up or down along the end wall 5 of the pulp dryer when using an extraction device 1 u2032 1 u2033 according to the example of the figure the operator 20 has enough space to move on the maintenance platform 2 as the pulp web 8 does not travel through or over the maintenance platform one of the advantages of an extraction device 1 u2032 1 u2033 according to the example is that the pulp web 8 needs not to be manually extracted from the dryer 4 as the backing roll 17 of the device 1 u2032 1 u2033 is set inside the dryer 4 against the turn roll 7 u2033 fig3 shows the roof 90 of the pulp dryer and schematically one nozzle level 91 the maintenance platform 2 is arranged on such a long rail means that it can be guided even higher than the level presented in the figure beyond the roof 90 in fig4 a pulp web extraction.
