Abstract

An abrading machine is disclosed for abrasion of substantially plane items by use of rotating abrading discs (5,5'), which are moved simultaneously forwards and backwards transverse to the item and which preferably has downward extending abrasive lamellae. <??>The machine also preferably comprises one, typically two, opposite rotating abrading cylinders (7,7') fitted with elongated abrasive elements radially mounted on the abrading cylinder and has abrasive lamellae extending outwards from the cylinder. <??>By moving the abrading discs in a reciprocatory movement (4) transverse to the direction of feed (A) of the items it is achieved that traces etc. from the different abrasive properties of the abrading discs are eliminated as well as all parts of milled out areas etc. are evenly abraded, particularly if the abrading device is designed for using abrading discs with abrasive means comprising abrasive lamellae made of abrasive cloth and which extend downwards from the face of the abrading disc. <IMAGE>

Description

Patentkrav 1.

En slibeindretning ifølge krav 1, hvor ophængningsmidleme er indrettet til ophængning af slibeskiver med slibemidler, der strækker sig ud fra slibeskivens flade. 3. En slibeindretning ifølge krav 1 eller 2, der omfatter en flerhed af slibeskiver med underskåme spor til optagelse og fastholdelse af profillister, der udgør en del af langstrakte slibeelementer, der omfatter slibemidler, hvilke spor fortrinsvis strækker sig i hovedsagelig radiær retning på slibeskivens flade. 4. En slibeindretning ifølge et hvilket som helst af kravene 1-3, hvor organerne til at drive rotationen af slibeskiveme er indrettet, således at nabostillede slibeskiver roteres i modsat retning. 5. En slibeindretning ifølge et hvilket som helst af kravene 1-4, hvor slibeskivemes frem- og tilbagegående bevægelse har en slaglængde på 40-100%, fortrinsvis 60-85%, af skivemes diameter. 6. En slibeindretning ifølge et hvilket som helst af kravene 1-5, der omfatter en flerhed af slibeskiver med slibemidler, der omfatter slibelameller af et slibeark, såsom slibelærred, hvis forside har slibende egenskaber, og som strækker sig ud fra slibeskivens flade. 7. En slibeindretning ifølge krav 6, hvor slibemidlerne omfatter et elastisk støtteelement, fortrinsvis støttebørster, der understøtter bagsiden af slibelamelleme, hvilket støtteelement i det væsentlige har knap samme længde som lamellerne. 8. En slibeindretning ifølge krav 6 eller 7, hvor slibemidlerne er arrangeret i langstrakte slibeelementer, der strækker sig i hovedsagelig radiær retning på slibeskivemes flader. 9. En slibeindretning ifølge krav 8, hvor slibeelementeme omfatter profillister, hvori slibemidlerne er fastgjort, og som er optaget i underskåme spor i slibeskiveme. 10. En slibeindretning ifølge krav 8 eller 9, hvor der mellem slibeelementeme er arrangeret modholdselementer. 11. En slibeindretning ifølge krav 10, hvor hvert af modholdselementeme omfatter en modholdsbørste, der udviser en kortere længde end slibeelementeme, og som er monteret i en profilliste, der er optaget i et tilsvarende underskåret spor. 12. En slibeindretning ifølge et hvilket som helst af de foregående krav, der yderligere omfatter mindst én slibecylinder, der er arrangeret til at slibe en side af emnet efterfølgende at den er slebet af slibeskiveme, og som fortrinsvis omfatter slibemidler, der strækker sig i det væsentlige radiært ud fra en langstrakt kerne, hvilken slibecylinder strækker sig på tværs af fremføringsretningen og drives til at rotere om sin langsgående akse.Claim 1.

An abrasive device according to claim 1 or 2, comprising a plurality of abrasive discs with lower sheath grooves for receiving and retaining profile moldings which form part of elongated abrasive elements comprising abrasives, which grooves preferably extend in a substantially radial direction on the surface of the abrasive disc. . A grinding device according to any one of claims 1-3, wherein the means for driving the rotation of the grinding wheels are arranged so that adjacent grinding wheels are rotated in the opposite direction. A grinding device according to any one of claims 1-4, wherein the reciprocating movement of the grinding wheels has a stroke length of 40-100%, preferably 60-85%, of the diameter of the grinding wheels. An abrasive device according to any one of claims 1-5, comprising a plurality of abrasive discs with abrasives comprising abrasive lamellae of a abrasive sheet, such as abrasive cloth, the front of the abrasive having abrasive properties and extending from the surface of the abrasive disc. An abrasive device according to claim 6, wherein the abrasives comprise an elastic support member, preferably support bristles, which support the back of the abrasive slats, which support member is substantially the same length as the slats. An abrasive device according to claim 6 or 7, wherein the abrasive means are arranged in elongated abrasive elements which extend in a substantially radial direction on the surfaces of the abrasive discs. An abrasive device according to claim 8, wherein the abrasive elements comprise profiled moldings in which the abrasive means are secured and which are accommodated in lower-slit grooves in the abrasive discs. A grinding device according to claim 8 or 9, wherein retaining elements are arranged between the grinding elements.
