Description

467 971 10 15 20 25 30 35 uppfinningen kan placeras också i begränsade utrymmen. Besparingar i fråga om konstruktionsmaterial är också avsevärda jämfört med kända uppfinningar, eftersom lyftmanöverorganens ram bildar själva super- kalandern. Konstruktionen enligt uppfinningen håller alltid skarv- ningshuvudaggregatet vinkelrätt mot upprullningsvalsen oberoende av upprullningsvalsens diameter, varför en dyrbar skarvningsvals med stora dimensioner för att få en tillfredsställande skarvning kan undvaras. 467 971 10 15 20 25 30 35 the invention can also be placed in limited spaces. Savings in terms of construction materials are also considerable compared with known inventions, since the frame of the lifting actuators forms the supercalender itself. The construction according to the invention always holds the splicing head assembly perpendicular to the winding roller regardless of the diameter of the winding roller, so that an expensive splicing roller with large dimensions to obtain a satisfactory splicing can be dispensed with.

I det följande skall uppfinningen beskrivas mer i detalj med hjälp av exemplifierande utföringsformer, med hänvisning till bifogade ritningar, varvid: Fig. 1 visar en delvis schematisk sidovy av ett kontinuerligt gående avrullningsverk i enlighet med föreliggande uppfinning, innan pappersbanan huggs av och en skarvning med en ny rulle äger rum.In the following, the invention will be described in more detail by means of exemplary embodiments, with reference to the accompanying drawings, in which: Fig. 1 shows a partially schematic side view of a continuous rolling machine in accordance with the present invention, before the paper web is cut off and a joint with a new roll takes place.

Fig. 2 visar avrullningsverket i Fig. 1 framifrån och delvis genom strecklinjer.Fig. 2 shows the unwinding plant in Fig. 1 from the front and partly through dashed lines.

Fig. 3 är en planvy av avrullningsverket i Fig. 1, delvis genom strecklinjer.Fig. 3 is a plan view of the unrolling plant of Fig. 1, partly through dashed lines.

Fig. 4 är en sidovy av en annan utföringsform av ett kontinuerligt gående avrullningsverk i enlighet med uppfinningen.Fig. 4 is a side view of another embodiment of a continuous rolling mill in accordance with the invention.

Avrullningsverket enligt Fig. 1-3 fungerar på följande sätt: En pappersbana 12 matas från en avrullande rulle på upprullningsvalsen 2 via flera hårda valsar 15 och mjuka valsar 17 hos en superkalander 5 till ett återupprullningsverk (ej visat). Medan den avrullande rullen töms ut på upprullningsvalsen 2, som bärs upp av vagnar 4, rullas en ny rulle på upprullningsvalsen 8 medelst en hävarm 14 längs skenor 13 i ett avrullningsblock 3, som är anordnat i ett underrede ll under den uttömmande upprullningsvalsen och placerat i avrullningsenheten 1.The unrolling machine according to Figs. 1-3 works as follows: A paper web 12 is fed from a unrolling roll on the winding roller 2 via several hard rollers 15 and soft rollers 17 of a supercalender 5 to a rewinding machine (not shown). While the unrolling roller is unloaded on the winding roller 2, which is carried by carriages 4, a new roller is rolled on the winding roller 8 by means of a lever 14 along rails 13 in a unrolling block 3, which is arranged in a chassis 11 under the exhausting winding roller and placed in unrolling unit 1.

Hastígheten hos den nya rullen på upprullningsvalsen 8 synkroniseras 10 15 20 25 30 35 467 971 med pappersbanan 12, vilken pappersbana 12 sedan pressas mot en dubbelsidig bindemedelstejpremsa på den nya rullens yta medelst en borste hos ett skarvningshuvudaggregat 9. Den uttömmande pappersbanan huggs av och den tomma upprullningsvalsen 2 stoppas och lyfts bort.The speed of the new roll on the take-up roll 8 is synchronized with the paper web 12, which paper web 12 is then pressed against a double-sided adhesive tape strip on the surface of the new roll by means of a brush of a splicing head assembly 9. The exhaust and paper web is chopped. the empty take-up roller 2 is stopped and lifted off.

Under den nya rullens avrullning lyfts dess upprullningsvals 8 upp medelst av hydrauliska cylindrar styrda kedjor 7 längs vertikala gejdrar 6, som är monterade på superkalanderns 5 ram, med uppåt styrda vagnar 4, för att ge plats åt nästa nya rulle.During the unrolling of the new roll, its winding roller 8 is lifted up by means of hydraulic cylinders guided chains 7 along vertical guides 6, which are mounted on the frame of the supercalender 5, with upwardly guided carriages 4, to make room for the next new roll.

Upplyftningen av den uttömmande rullens upprullningsvals kan också åstadkommas genom att använda en skruvdomkraft eller, i enlighet med Fig. 4, medelst vridbart lagrade hävarmar 10 och hydrauliska cylindrar 15, som är monterade på superkalanderns 5 ram.The lifting of the winding roller of the exhaust roller can also be effected by using a screw jack or, in accordance with Fig. 4, by means of rotatably mounted levers 10 and hydraulic cylinders 15, which are mounted on the frame of the supercalender 5.
