Embodiment Construction

[0021] figure 1 shows generally a plant for the production of expanded material, in which sheet metal 1 is supplied in the direction of arrow 3 to a cutting device indicated generally at 4 by means of a feed device, for example constituted by a conveyor device 2 . For further processing or processing, after passing through the cutting device 4 , the expanded material 1 processed with cuts or slits or perforations in the cutting device 4 is wound up in a subsequent stretching and / or winding device 5 .

[0022] Such as figure 1 As shown, cutting device 1 comprises a roll 6, is provided with the blade or cutter 7 that is substantially equidistant from each other schematically shown in many figures on the whole circumference of roll 6, and roll 6 can rotate around axis 8 along the direction of arrow 9, In order to make a plurality of cuts or slits or perforations in the sheet metal or raw material 1 as it passes through the material by means of blades or cutters 7 protruding from...

Abstract

The present invention relates to a device which uses metal sheet for producing extensible material. The device comprises a feeding device which is used for carrying in metal sheet, a cutting device which is used for forming a notch or through hole in the metal sheet, and a post-positioned extending and / or coiling device. The cutting device (4) is composed of a roller (6) which is provided with a plurality of cutters or blades (7) projected from a surface (10) and rotates around an axis (8) that is basically perpendicular with the input direction (3) of metal sheet (1), wherein at least the surface (12) of the opposite roller is made of elastic material. An effect that the opposite roller leans against the surface (10) of roller (6) which is provided with the cutters or blades (7) is basically obtained in the cutting process at the state of forming the passing clearance of metal sheet (1). Thereby the notches of different patterns can be manufactured in the metal sheet (1) with an extraordinary small thickness with a simple device.

Description

technical field [0001] The invention relates to a plant for the production of expanded material from sheet metal, comprising a supply device for feeding the sheet metal, a cutting device for forming cuts or perforations in the sheet, and a subsequent spreading and / or winding device . Background technique [0002] Such expanded materials made of sheet metal are used, for example, for containers filled with, in particular, flammable liquids or gases, in order to prevent the explosion or explosive combustion of the objects contained in such containers. Such expanded material is especially made of thin metal foil, with which the expanded material produced with many cuts or slits and wound into shaped bodies should be able to retain its shape for a long time, where In this case they displace relatively little fluid or liquid, but should substantially completely fill a container to be filled with it, in order to provide the desired, especially explosion-proof protection. In orde...
