Ritningssammandrag I det följande kommer uppfinningen att beskrivas i ytterligare detalj med referens till bifogade ritningar i vilka Fig. 1A - lC illustrerar rörelse hos en stödvals relativt en rotationslcniv hos en ro- terbar skåranordning; 10 20 25 30 527 748 3 Fig. 2 illustrerar en spindel ansluten till stödvalsen för utförande av stödvalsens rö- relse visadi Fig. lA - IC.Drawing Summary In the following, the invention will be described in further detail with reference to the accompanying drawings in which Figs. 1A - 1C illustrate movement of a support roller relative to a rotational blade of a rotatable notch device; Fig. 2 illustrates a spindle connected to the support roller for performing the movement of the support roller shown in Figs. 1A - 1C.
Fig. 3 illustrerar en krafikälla för möjliggörande av stödvalsens rörelse visad i Fig. 1A - lC. l Fig. 4 visar ett kontrollmedel för att kontrollera stödvalsens rörelse visad i Fig. 1A - IC.Fig. 3 illustrates a collar source for enabling the movement of the support roller shown in Figs. 1A - 1C. Fig. 4 shows a control means for controlling the movement of the support roller shown in Fig. 1A - IC.
Detaljbeshivning Fig. 1A visar en roterbar skäranordrring 2 innefattande en rotationskniv 4 och en stödvals 6 med parallella axlar i deras axiella utsträckning. Rotationskniven 4 inne- fattar en axel 8 och en integrerad trumma 10 försedd med anliggningsdelar 12 och knivdelar 14. Även stödvalsen 6 innefattar en axel 16 och en integrerad tumma 18 med första och andra ändar 19a, 19b och en yta 20 av ett material som är mjukare än knivdelens 14 material. Anliggningsdelarna 12 anligger mot ytan 20 och knivdelar- na 14 utför en skâroperation tillsammans med ytan hos den väv som skall producera Lex. sanítetsbindor eller blöjor.Detailed description Fig. 1A shows a rotatable cutting arrangement 2 comprising a rotating knife 4 and a support roller 6 with parallel axes in their axial extent. The rotating knife 4 comprises a shaft 8 and an integrated drum 10 provided with abutment parts 12 and knife parts 14. The support roller 6 also comprises a shaft 16 and an integrated drum 18 with first and second ends 19a, 19b and a surface 20 of a material which is softer than the material of the knife part 14. The abutment parts 12 abut against the surface 20 and the knife parts 14 perform a cutting operation together with the surface of the fabric which is to produce Lex. sanitary napkins or diapers.
Det bör dock noteras att en hylsa kan vara anordnad på en stödvalstrumma varvid hylsan innefattar nämnda yta 20. Likaledes kan en hylsa innefattande anliggningsde- larna 12 och knivdelarna 14 vara anordnade på rotationsknivtrumman 10.It should be noted, however, that a sleeve may be arranged on a support roll drum, the sleeve comprising said surface 20. Likewise, a sleeve comprising the abutment parts 12 and the knife parts 14 may be arranged on the rotating knife drum 10.
Stödvalsmnnman 18 har en större axiell utsträckning än rotationslnrivüumman 10. I Fig. 1A utförs skäroperationen vid den första axiella änden 19a hos trumman 18.The support roller selector 18 has a larger axial extent than the rotary thruster 10. In Fig. 1A, the cutting operation is performed at the first axial end 19a of the drum 18.
I Fig. IB har stödvalsmnnman 18 förflyttats till rotafionsknivsmunmans 10 axiella centrum.In Fig. 1B, the support roller nozzle 18 has been moved to the axial center of the rotary knife nozzle 10.
I Fig. IC har stödvalstrurnman 18 förflyttats till rotationsknivsmimmans 10 andra axíella ände 19b. 20 25 527 748 Vid skäroperafionen enligt Fig. 1A kornmer knivdelamas 14 axiella utsträckning att orsaka nötning av ytan 20 med en area motsvarande nämnda axiella utsträckning på grund av det hårdare materialet hos knivdelarna och nötning härstammande från va- ven. Genom att röra stödvalsen relativt rotationslcnivtrumman såsom visas i Fig. 1A och IB är det möjligt att förstora den nötta arean.In Fig. 1C, the support roller frame 18 has been moved to the second axial end 19b of the rotary knife mesh 10. 527 748 In the cutting operation according to Fig. 1A, the axial extent of the knife parts 14 causes abrasion of the surface 20 by an area corresponding to said axial extent due to the harder material of the knife parts and abrasion originating from the web. By moving the support roller relative to the rotary blade drum as shown in Figs. 1A and 1B, it is possible to enlarge the worn area.
I Fig. 2 visas schematiskt en spindel 22 som är fast ansluten till stödvalsens 6 axel 16. Spindeln 22 är försett med en mutter ansluten till en ej visad ram. Genom att vrida muttern 22 kommer stödvalsen 6 att röra sig axiellt in i stödvalsens axiella ut- sträckning och parallellt med rotatinnsknivens 4 axiella utsträckning I Fig. 3 visas en krafikälla 26 orsakande rotation av stödvalsens 6 axel 16. Givetvis kan krafikällan vara konstruerad att rotera spindeln 22 i muttern 24 såsom visad i Fig. 2.Fig. 2 schematically shows a spindle 22 which is fixedly connected to the shaft 16 of the support roller 6. The spindle 22 is provided with a nut connected to a frame (not shown). By turning the nut 22, the support roller 6 will move axially into the axial extent of the support roller and parallel to the axial extent of the rotary knife 4. 22 in the nut 24 as shown in Fig. 2.
I Fig. 4 är lcrafilcällan visad i Fig. 3 försedd med kontrollmedel 28 såsom en kon- trollpanel eller en dator.In Fig. 4, the lcra source shown in Fig. 3 is provided with control means 28 such as a control panel or a computer.
Rotation av stödvalsen 6 genom manuellt vridande av spindeln eller via en krañkäl- la kan kontrolleras att orsaka en intennittent rörelse hos stödvalsen relativt rota- tionslcnivtrumman 10. Den intermittenta rörelsen kan vara mer eller mindre kontinu- erligt även fast den samtidigt är intermittent.Rotation of the support roller 6 by manually rotating the spindle or via a crane source can be controlled to cause an intense movement of the support roller relative to the rotary blade drum 10. The intermittent movement can be more or less continuous even though it is simultaneously intermittent.
Altemativt kan rörelse vara kontinuerlig, antingen fiån ena sidan till den andra, eller oscillerande.Alternatively, movement can be continuous, either from one side to the other, or oscillating.
Rörelsen kan vara snabb eller långsam. 527 748 5 Givetvis kan rotationsuumman i stället röras relativt stödvalsen. Dessutom kan både ' rotationslcnivtrurnman och stödvalstrumman vara rörliga relativt varandra.The movement can be fast or slow. 527 748 Of course, the rotary bucket can instead be moved relative to the support roller. In addition, both the rotary level tube and the support roller drum may be movable relative to each other.
