Definitions

  • the invention relates to a turning bar for deflecting a web according to the preamble of claim 1.
  • Rotary printing presses after printing using one or more longitudinal chords in two or more partial paper webs.
  • Such partial paper webs are laid over by turning bars with or without turning over and in a changeable order to form a strand.
  • the turning bars are usually arranged horizontally in a side frame at an angle of 45 °.
  • the part paper web runs along a narrow path, instead of feeding the part paper web through the left frame side, the part paper web is fed through the right gesture 11 side, e.g. B. for mixing paper webs / so it is in the above-mentioned turning bar arrangement nachtei lig that the turning bar must either be converted or replaced so that between the turning bar and Tei lpapierbahn jewei ls an air cushion is available.
  • DE 41 30 678 A1 is a turning bar known, which has a spiral groove arranged next to the guide region of the partial paper web for guiding a pull-in belt.
  • the disadvantage here is that the pull-in belt has to overcome a large frictional resistance when driving around this turning bar. As a result of the high tensile forces that occur in the pull-in belt, they can tear the same.
  • the object of the invention is to create a turning bar that can be bypassed from "two sides".
  • the Vortei le achievable with the invention are that the turning bar on both sides, ie from a left side or half (Fig. 2) or from a right side or half (Fig. 3) can be avoided.
  • the half facing the paper web has air openings which can be changed with little effort by half a turn of the tube.
  • a conversion or exchange of turning bars can be avoided in particular if Te 1 Ipapi e rbahnen in so-called mixing towers are mixed in at a different location, ie in another level of the mixing tower.
  • a holder of the turning bar according to the invention is provided with a helical, compressed air guide groove for smooth guidance for a pull-in belt.
  • Fig. 1 is a front view of an inventive
  • Fig. 2 shows a cross section through an inventive
  • FIG. 3 shows a cross section analogous to FIG. 2, but with a guide tube rotated through 180 ° in the end position B;
  • Fig. 4 is an enlarged view of a
  • a turning bar 1 consists of a pipe with air openings ri tt openings 2 z. B. Guide tube 3.
  • the guide tube 3 is at both ends via bushings 4; 6 in the side view of holders 7; 8 at an angle of 45 ° to the paper web direction, z. B. by means of ni chtdargest l Iter clamps if necessary, also on beengestel Ifesten trusses, arranged.
  • the air outlet openings 2 are on the circumference of the guide tube 3 at an angle alpha less than 165 ° and distributed over a length which is a paper web width minus an amount, for. B. corresponds to 30 mm for a protrusion.
  • Both brackets 7; 8 are through a connec tion tube 9, which both brackets 7; 8 keeps at a distance, firmly connected.
  • the connecting pipe 9 has air outlet openings 11 distributed over its entire length and circumference.
  • the Verbl ndungs tube 9 is at one end with a connector 10 located in the right bracket 8 for low-pressure air with an air pressure of z. B. 0.3 connected up to 0.6 bar.
  • the guide tube 3 can be rotated from a first end position A (FIGS. 1 and 2) through 180 ° about its axis of rotation 5 into a second end position B (FIG. 3)
  • the guide tube 3 is in its respective end position A; B stored fixable. That can e.g. B. can be achieved in that on one end of the guide tube 3 two diametrically opposite circumferential semicircular recesses 12; 13 are arranged, with either a recess 13 acting against a locking handle 14 movable in the radial direction of the guide tube 3.
  • the locking handle 14 is moved against the force of a spring 15, which is supported between the head of a ha ition-resistant threaded bolt 31 and a collar 32 of the locking handle 14.
  • the bearing bushes 4; 6 can consist of plastic and on the bracket 7; 8 be pressed on. Sealing rings 16 are used to seal the low-pressure compressed air against leakage through the gaps in the slide bearing; 17 set.
  • a holder 7 of the guide tube 3 has a helical guide groove 18 for receiving a feed belt (not shown) for a web.
  • On the groove base or the bottom surface 19 of the groove there are air outlet openings 21 to 25 which are designed as radial bores and into an axial one central bore 27 of the left bracket 7 open.
  • air outlet openings 21 to 25 which are designed as radial bores and into an axial one central bore 27 of the left bracket 7 open.
  • Air outlet opening 21 to 25 in the bottom surface 19 of the groove 18 each have a known ball seat valve 33 arranged so that the passage of the feed belt opens the ball Is 1 tzvent i les 33 (Fig. 4).
  • the axial bore 27 is with a connection 28 located on or in the holder 7 for
  • Hochdruc k-B read air with an air pressure of z. B. 1.5 to 4 bar in connection.
  • the helical guide groove 18 makes a half turn on the circumference of the left bracket 7, so that it becomes possible to use a pull-in tape for a web, e.g. B. to run a paper web 29 smoothly over the turning bar 1.
  • the turning bar 1 it is also advantageous if at least one, for. B. the left bracket 7 has a second guide groove 34 arranged in the opposite direction to the first guide groove 18.
  • This guide groove 34 is formed in the same way as the guide groove 18 described above and is equipped with non-specific air outlet openings. It is also possible to design the right holder 8 with a guide groove 18 or with a second guide groove 34. It is also possible on both brackets 7; 8 of the turning bar 1 to introduce a guide groove, the guide grooves should then run in opposite directions to each other. In this case there is also a separate connection for high pressure blow air.

Abstract

L'invention concerne une barre de retournement pouvant être sollicitée par de l'air de soufflage, sur laquelle aucune opération de modification ou de suspension ne devrait intervenir lorsque la bande de papier change de direction. A cet effet, la barre de retournement comporte un tube de guidage muni d'orifices d'évacuation d'air d'un côté, c.-à-d. sur le côté faisant face à la bande de papier, ledit tube étant monté aux deux extrémités, de façon solidaire du bâti latéral, dans des éléments de fixation. Au moins un élément de fixation comporte une rainure de guidage prévue pour une bande d'entrée et pouvant être sollicitée par de l'air de soufflage. Le tube de guidage peut être monté de manière à pouvoir tourner à 180° autour de son axe de rotation pour passer de manière facultative d'une position finale dans une seconde position finale.
