The suction chamber 38 is connected to a suction line 41, which leads to a suction air station, not shown.
Das die Papierbahn 12 fördernde Obertrum 21 der Saugbänder 26; 27 ist auf seiner die Papierbahn 12 fördernden Seite und in papierleitkammernähe blasluftbeaufschlagbar ausgebildet. Dies geschieht durch eine in der Nähe der Papierleitkammer 15, d. h. über dem Ende des Bahnzufuhr-Saugtisches 13 bzw. des Anfanges des Bahnabfuhr-Saugtisches 16 über dem Saugband 26; 27 befindlichen Blaskammern 42; 43. Dabei befindet sich ein mit Löchern 40 versehenes Blaskammerblech 45; 50 in einem Abstand g über dem Saugband 26; 27. Die Blaskammern 42; 43 sind jeweils mit flexiblen Blasluftleitungen 44; 46 verbunden.The upper run 21 of the suction belts 26; 27 is formed on its side that conveys the paper web 12 and in the vicinity of the paper guide chamber can be subjected to blowing air. This is done by a near the paper guide chamber 15, ie above the end of the web feed suction table 13 or the beginning of the Web removal suction table 16 above the suction belt 26; 27 located blow chambers 42; 43. There is a blow chamber plate 45 provided with holes 40; 50 at a distance g above the suction belt 26; 27. The blow chambers 42; 43 are each with flexible blown air lines 44; 46 connected.
Die Blaskammern 42; 43 können jeweils durch eine Verlängerung der Zwischenwand 36 sowie des rinnenförmigen Gehäuses 39 gebildet sein, wobei zwischen der Saugkammer 38 und dem Blaskammern 42; 43 eine Trennwand 47; 48 eingesetzt ist.The blow chambers 42; 43 can each be formed by an extension of the intermediate wall 36 and the channel-shaped housing 39, with between the suction chamber 38 and the blowing chambers 42; 43 a partition 47; 48 is used.
Die Vorrichtungen zum Wenden einer Bahn funktioniert wie folgt: Die nach Fig. 1 und 3 in die Wendeeinheit 01 einlaufende Spitze der Papierbahn 12 wird von den angetriebenen Saugbändern 26 des Bahnzufuhr-Saugtisches 13 übernommen und dem von der Blaskammer 42 beblasenem Eingang der Papierleitkammer 15 zugeführt. Die beblasene Wendestange 14 lenkt den Anfang der Papierbahn 12 zu dem von der Blaskammer 43 beblasenen Ausgang der Papierleitkammer 15 und übergibt den Anfang der Papierbahn 12 nachfolgend den Saugbändern 27 des Bahnabfuhr-Saugtisches 16 zur Weitergabe an die Wendeeinheit 02.The devices for turning a web function as follows: The tip of the paper web 12 entering the turning unit 01 according to FIGS. 1 and 3 is taken over by the driven suction belts 26 of the web feed suction table 13 and fed to the entrance of the paper guiding chamber 15 blown by the blowing chamber 42 , The blown turning bar 14 directs the beginning of the paper web 12 to the outlet of the paper guiding chamber 15 blown by the blowing chamber 43 and subsequently passes the beginning of the paper web 12 to the suction belts 27 of the web removal suction table 16 for forwarding to the turning unit 02.
Dort wird die Papierbahn 12 in gleicherweise gefördert, so dass diese um 180° gewendet und bahnbreitenversetzt die Wendeeinheiten 01; 02 verlassen kann.There, the paper web 12 is conveyed in the same way, so that it is turned by 180 ° and the web units 01; 02 can leave.
Außerhalb des Papierbahneinzugsvorganges, d. h. während der Produktion kann die Saugkammer 38 in Betrieb genommen werden, so dass der anfallende Papierstaub abgesaugt werden kann.Outside the paper web feeding process, i.e. H. During production, the suction chamber 38 can be put into operation, so that the paper dust which arises can be suctioned off.
Nach einem anderen Ausführungsbeispiel ist die in Fig. 4 und 5 gezeigte einteilige Papierleitkammer 15 sowie die Saugkammer 38 zweiteilig ausgebildet. Es sind zwei halblange, d. h. jeweils 90° getrennt die Wendestange 14 oder 20 umgebende Zwischenwände 49; 51 vorgesehen, so dass zwei Saugkammern 52; 53 entstehen, die jeweils von zwei äußeren Gehäusen 54; 56 begrenzt werden. Somit ist für jede Saugkammer 52; 53 eine separate Saugleitung 57; 58 erforderlich.According to another embodiment, the one-piece paper guide chamber 15 shown in FIGS. 4 and 5 and the suction chamber 38 are formed in two parts. There are two half-length, ie each 90 ° separated the turning bar 14 or 20 surrounding partition walls 49; 51 is provided so that two suction chambers 52; 53 arise that each of two outer housings 54; 56 can be limited. Thus, for each suction chamber 52; 53 a separate suction line 57; 58 required.
Mittels eines Schanieres 59 und eines nicht dargestellten Antriebes, z. B. mittels eines Arbeitszylinders oder von Hand ist eine der beiden Saugkammern 52; 53 in einem Winkel α von 180° in eine wendestangenferne Ruhestellung H verschwenkbar.By means of a hinge 59 and a drive, not shown, for. B. by means of a working cylinder or by hand is one of the two suction chambers 52; 53 can be pivoted at an angle α of 180 ° into a rest position H remote from the turning rod.
