Abstract

A drum half of wood destined to form part of a wooden drum for a rotary die cutting machine is disclosed. The cutting pattern (3) of the drum half (1) is produced by means of laser beam cutting, and the laser-beam-cut grooves (6) extending in the circumferential direction of the drum half is formed of chain bridges (8) adjacent to the edges of the drum half. In a method of manufacturing a rotary die cutting machine, laser beam cutting is used to produce the chain bridges in which 4-mm-long wooden bridges (9) alternate with 4-mm-long cuts (10).

Description

505 327 10 15 20 25 30 Uppfinningens ändamål Är att eliminera detta problem. 505 327 10 15 20 25 30 Object of the Invention Is to eliminate this problem.

Uppfinningen Enligt uppfinningen elimineras problemet med hjälp av de i patentkraven och i det följande definierade bryggkedjorna, som ersätter de tidigare kända i omkrets- led löpande spåren invid skarven mellan trumhalvorna.The invention According to the invention, the problem is eliminated by means of the bridge chains defined in the claims and in the following, which replace the previously known circumferential grooves next to the joint between the drum halves.

Utföringsform av uppfinningen En utföringsform illustreras på bifogade ritningar, där fig 1 är en planvy av två trumhalvor, fig 2 är en delvy i perspektiv av en trumhalva delvis försedd med stanslinjer och fig 2A och 2B visar en förstoring av de streckinramade detaljerna i fig 2.Embodiment of the Invention An embodiment is illustrated in the accompanying drawings, in which Fig. 1 is a plan view of two drum halves, Fig. 2 is a partial perspective view of a drum half partially provided with punch lines, and Figs. 2A and 2B show an enlargement of the dashed details of Fig. 2.

I fig 1 visas en trätrumma bestående av två trum- halvor 1. Skarven mellan trumhalvorna har hänvisnings- siffran 2. Trumhalvorna 1 har ett laserskuret spårmönster 3 för stansning av och biglinjeformning i ämnen till två fyrpunktslimmade tråg i wellpapp. Spårmönstret 3 är så gjort att 8 mm långa bryggor 4 kvarblir mellan skären 5.Fig. 1 shows a wooden drum consisting of two drum halves 1. The joint between the drum halves has the reference number 2. The drum halves 1 have a laser-cut groove pattern 3 for punching and bead-line forming in blanks for two four-point glued trays in corrugated cardboard. The groove pattern 3 is made so that 8 mm long bridges 4 remain between the inserts 5.

I dessa spår 6 insätts stansstållinjer, som har urtag- ningar för gränslande av bryggorna 5.In these grooves 6 punch steel lines are inserted, which have recesses for delimiting the bridges 5.

Enligt uppfinningen är de rotativa spår, dvs i om- kretsled löpande spår 6, som ligger intill de skarven 2 avgränsande kanterna av trumhalvorna utformade brutna, dvs som en bryggkedja 8 av 4 mm bryggor 9 omväxlande med 4 mm skär 10 (8 mm cc), varvid en sådan brygga 9 definie- rar kanten.According to the invention, the rotating grooves, i.e. circumferential grooves 6, which lie next to the joints 2 delimiting the edges of the drum halves are designed to be broken, ie as a bridge chain 8 of 4 mm bridges 9 alternating with 4 mm inserts 10 (8 mm cc) , wherein such a bridge 9 defines the edge.

I fig 2A visas i den övre delen en i nämnda spår 6 helt indriven stanslinje 11 och i den undre delen en i spår 6 blott delvis indriven stanslinje 12. Det framgår att stanslinjerna 11, 12 är i sin längdriktning urtagna med jämna avstånd, som är 4 mm, så att den passar i bryggkedjan 8. Urtagningarna är 13 mm djupa för att medge krumning av stanslinjen.Fig. 2A shows in the upper part a punch line 11 which is completely driven into said groove 6 and in the lower part a punch line 12 which is only partially driven into groove 6. It can be seen that the punch lines 11, 12 are recessed in their longitudinal direction 4 mm, so that it fits in the bridge chain 8. The recesses are 13 mm deep to allow curvature of the punch line.
