DETAILED DESCRIPTION OF THE EMBODIMENTS
(23) FIG. 1a illustrates an embodiment of a manufacturing method 100 in accordance with the present invention. Armor elements 102, such as ceramic tiles, are arranged in connection with a metal profile extrusion arrangement 104. The armor elements 102 are aligned after the die 106 of the metal profile extrusion arrangement 104. The metal profile extruder comprises a mandrel 108 and a mandrel holder 110.
(24) The armor elements 102 are supported with guides 112 and a stopper 114. The metal profile from the metal profile extrusion arrangement pushes the guides 112 forward. The stopper 114 keeps the armor elements 102 in place such that the metal profile settles around the armor elements 102 such that the armor elements remain inside the metal profile.
(25) FIG. 1b illustrates an embodiment of a manufacturing method 100b in accordance with the present invention. The arrows 103b represent the malleable material compressed flow. A tongue 105b divides the material flow. The metal profile extrusion arrangement 104b comprises a weld chamber 107b and a bearing 109b that forms the extruded metal profile 111b. The extruded metal profile 111b pushes the guides 112b forward. Rollers 115b are arranged on both sides of the armor elements to compress the extruded metal profile 111b around the armor elements. The rollers 115b may also straighten and/or press forward the metal profile 111b. The armor elements are supported with a stopper 114b.
(26) Metal profile extrusion materials may be e.g. aluminium, brass, copper, lead, tin, magnesium, zinc, steel and/or titanium.
(27) Ceramic elements may comprise for example aluminium oxide, silicon carbide, boron carbide and/or any other ceramic material suitable for ballistic armor and/or suitable for other structural purposes of the present invention.
(28) FIG. 2 illustrates an embodiment of a manufacturing method 200 in accordance with the present invention. Armor elements 202 are aligned after a direct extrusion arrangement 204. The armor elements 202 may be arranged directly after the die 206. The billet 216 is driven by a punch 218 with a dummy block 220. The billet 216 is inside a billet chamber 222. The billet 216 is pushed through a die 206. The die 206 forms the billet to a metal profile that is guided around the armor elements 202 such that the armor elements remain inside the metal profile. There may be intermediate elements 224a, 224b between the armor elements 202. Such intermediate elements 224a, 224b may be produced from a material that distinguishes from the material of the armor elements 202. The intermediate elements may be manufactured from similar material as the billet for the metal profile, or other material suitable for cutting and machining with standard tools. The intermediate elements may be utilized later on to cut the armor structure on the location of the intermediate elements, for example. Additionally, alternatively, the ballistic armor may be attached to another surface by utilizing the intermediate elements, for example by screwing through the intermediate elements. The armor elements and/or intermediate elements may be supported with guides 212 and a stopper 214. The guides 212 may be pushed forward by the extruded profile.
