means of compressed air, it is subsequently pulled, together with the web of material secured thereto, through the web guide path and is then removed from it.
The second solution is solved by the features of claim 2.
The sub-claims contain preferred embodiments of a device accordlng to claim 2.
While the feature of claim 3 guarantees that the belt is rellably transported through the web guide path, the feature of clalm 4 makes it possible to reduce the time required for the in-~ertlon since the new supply reel can already be prepared before-hand and during the downtime only the belt must be coupled to the connectlng member secured to the start of the web of material.
~rlef descrlDtlon o the drawina The drawing serves to explain the present invention on the basls of a ~imply illustrated exemplary embodiment.
Figure 1 shows a longitudinal section in the direction of web travel through a winding machine with a ;
web in~ertion device according to the present invention, :
Figure 2 shows an enlarged section of the guide channel.
Wav of carrving out the invention The winding machine, schematically illustrated in Figure 1, is a so-called supporting roller-rolling machine in which the 4'~
web 1 of material, a web of paper or board up to 8 meters in wldth, arriving from an unrolling unit 2 is divided longitudinally lnto lndividual webs that are wound into reels 3. The reels 3, which are arranged alternately on both sides of the vertical line durlng wlnding, lie on a driven supporting roller 4. The web 1 is gulded to the supporting roller 4 from below so that the web is partlally wound around this roller. A longitudinal cutting device 5, which divides the web 1 into individual webs, is located at a di~tance below the supporting roller 4.
When feeding the web 1 to a carrier or supporting roll- ~ ;
er rom below, lt ls necessary that the web 1 be guided at least ln part underfloor so that a free space remains between the un-rolllng unlt 2 and the winding machine for unloading the full reel~ 3. Guide pulleys 6 to lO are used to guide the web, these gulde pulleys first of all deflecting the web 1 downwards into the underfloor area and then approximately horizontally up to the area ;
below the supporting roller 4. There the web is turned approxi- ;~
mately vertically upwards by a guide pulley 11. A deflection ;
pulley 12, whlch follows the vertical path in which the longitud$- ';;
nal cuttlng device S i9 disposed, guides the web approximately tangentially to the supporting roller 4. ~ ~
The elements describ0d herebelow are used to insert a new web 1 into the winding mach1ne, for example after changing the ~upply reel in the unrolling unit 2 or after the web tears. A
guide element, preferably a guide channel 13, for a tow belt lS is arranged approximately centrally to the working width along the i web guide path at a short distance therefrom. The guide channel ; ;
13 has a u-shaped cross-section and is open towards the plane of , :-, "
2~41~7 -, the web guide. It is between 50 mm and 100 mm wide and the leg is approximately 20 mm high. The channel 13 is located below the approximately horizontal section of the web guide path and extends up to the last deflection pulley 11 in front of the longitudinal cuttlng device 5. To avoid crossing the web guide path in an lnterfering manner, the guide channel 13 has openings in the area of the downwardly deflecting guide pulley 8. A curved portion 13.1 of the guide channel 13 that i9 open downwardly is located ~bove the guide pulley 8, whereby spaces towards the channel 13 were left for the web 1 to cross.
The guide channel 13 is interrupted at regular inter-vals, approxlmately every 0.5 - 1 meters. Flat-section nozzles 14 are respectlvely arranged at the openings, said nozzles blowing lamlnarly flowlng compres~ed air into the channel 13 in the direc-tion of web travel, whereby the distance of the blow-off outlets from the bottom of the channel 13 is less than 10 mm, preferably ~;
0.5 mm to 1 mm. The construction of such flat-section nozzles is described ln German patent 24 13 614. In this way compressed air flows through the entire channel 13 approximately parallel and lamlnarly to the base.
Arranged in the vertical area between the guide pulleys 11 and 12 is a channel portion 13.2 that can be raised between the extended knives of the longitudinal cutting device 5 up to the upper guide pulley 12 and can be lowered to below the lower guide pulley 11. A correspondingly curved guide channel member 13.3 is provided in the area of the guide pulley 12 and, because the web 1 crosses the guide channel 13 again at this point, is followed at a , , . . ,. , .. , . . . , . . : . .; ,, . ~ . , , . . . : . . ,. .: .
