Claims (13)

AnsprücheExpectations 1. Vakuumniederhaltevorrichtung zum lösbaren Halten eines Blattmaterials, umfassend:1. A vacuum hold-down device for releasably holding a sheet material, comprising: a) einen Träger mit mehreren voneinander beabstandeten Öffnungen; und(a) a carrier having a plurality of spaced-apart openings; and b) eine mit dem Träger verbundene mikroporöse Schutzbeschichtung, die dazu dient, eine nicht zersetzende Trennung von dem Träger zu verhindern, die Öffnungen zu bedecken und eine Bewegung der Beschichtung relativ zu dem Träger zu verhindern, wobei der Träger elastisch verformbar ist und eine gleichmäßige Dichte hat.b) a microporous protective coating bonded to the carrier, serving to prevent non-degradable separation from the carrier, to cover the apertures and to prevent movement of the coating relative to the carrier, the carrier being elastically deformable and having a uniform density. 2. Vakuumniederhaltevorrichtung nach Anspruch 1, wobei der Träger ein Förderband ist.2. Vacuum hold-down device according to claim 1, wherein the carrier is a conveyor belt. 3. Vakuumniederhaltevorrichtung nach Anspruch 1, wobei der Träger feststehend ist.3. Vacuum hold-down device according to claim 1, wherein the carrier is fixed. 4. Vakuumniederhaltevorrichtung nach Anspruch 1, wobei die Beschichtung den Träger zwischen den voneinander beabstandeten Öffnungen bedeckt.4. The vacuum holddown device of claim 1, wherein the coating covers the carrier between the spaced-apart openings. 5. Vakuumniederhaltevorrichtung nach Anspruch 1, wobei die Beschichtung den Träger zwischen den voneinander beabstandeten Öffnungen bedeckt.5. The vacuum holddown device of claim 1, wherein the coating covers the carrier between the spaced-apart openings. 6. Vakuumniederhaltevorrichtung nach Anspruch 1, wobei die Beschichtung den Träger nur in einem lokalen Bereich der Öffnungen bedeckt.6. Vacuum hold-down device according to claim 1, wherein the coating covers the carrier only in a local area of the openings. 7. Vakuumniederhaltevorrichtung nach Anspruch 1, wobei die Beschichtung einen ausreichend gewundenen Strompfad hat, um an den voneinander beabstandeten Öffnungen über einen größeren Bereich als der Bereich der voneinander beabstandeten Öffnungen eine Druckdifferenz zu verteilen.7. The vacuum holddown device of claim 1, wherein the coating has a sufficiently tortuous flow path to distribute a pressure differential at the spaced apart openings over a larger area than the area of the spaced apart openings. 8. Vakuumniederhaltevorrichtung zum Halten eines elastischen Blattmaterials, umfassend:8. A vacuum hold-down device for holding an elastic sheet material, comprising: a) einen Träger mit mehreren voneinander beabstandeten Öffnungen; und(a) a carrier having a plurality of spaced-apart openings; and b) eine mit dem Träger fest verbundene durchlässige Vakuumbeschichtung, die dazu dient, eine nicht zersetzende Trennung der Beschichtung von dem Träger zu verhindern und die Öffnungen zu bedecken, wobei die Beschichtung derart gewählt ist, daß ein Eindringen des Blattmaterials in eine öffnung des Trägers im wesentlichen verhindert wird.b) a permeable vacuum coating firmly bonded to the carrier, which serves to prevent non-decomposable separation of the coating from the carrier and to cover the openings, the coating being selected such that penetration of the sheet material into an opening of the carrier is substantially prevented. 9. Anspruch 9: gestrichen9. Claim 9: deleted 10. Anspruch 10: gestrichen10. Claim 10: deleted 11. Vakuumniederhaltevorrichtung nach Anspruch 8, wobei die Beschichtung zur Verbindung mit dem Träger wahlweise gebondet, haftgebondet, mit diesem verschweißt oder einstückig mit diesem ausgebildet ist.11. Vacuum hold-down device according to claim 8, wherein the coating for connection to the carrier is optionally bonded, adhesively bonded, welded thereto or formed as one piece therewith. 12. Schneidevorrichtung, umfassend:12. Cutting device comprising: a) einen Träger mit mehreren voneinander beabstandeten Öffnungen;(a) a carrier having a plurality of spaced-apart openings; b) ein Schneidrad (Schneidewerkzeug), das mit der Förderfläche translatorisch bewegbar ist, um gegen den Träger gedrückt zu werden; undb) a cutting wheel (cutting tool) which is translationally movable with the conveying surface in order to be pressed against the carrier; and c) eine durchlässige Vakuum-Schutzbeschichtung, die mit dem Träger verbunden ist, um die Öffnungen zu bedecken, wobei die Beschichtung derart hergestellt ist, daß ein Kontakt zwischen dem Schneidrad (Schneidewerkzeug) und dem Träger ermöglicht wird.c) a permeable vacuum protective coating bonded to the carrier to cover the openings, the coating being made to allow contact between the cutting wheel (cutting tool) and the carrier. 13. Schneidevorrichtung zum Schneiden eines elastischen Blattmaterials, umfassend: 13. A cutting device for cutting an elastic sheet material, comprising: a) einen Träger mit mehreren Öffnungen;(a) a carrier with several openings; b) ein Schneidrad (Schneidewerkzeug), das relativ zum Träger translatorisch bewegbar ist, um sich über die Öffnungen hinweg zu bewegen; undb) a cutting wheel (cutting tool) which is translationally movable relative to the carrier in order to move across the openings; and c) eine durchlässige Vakuumbeschichtung, die mit dem Träger verbunden ist, um die Öffnungen zu bedecken, wobei die Beschichtung derart gewählt ist, daß sie das Blattmaterial ausreichend hält, wenn es eine öffnung bedeckt, um ein Schneiden des Blattmaterials zu ermöglichen, wenn sich das Schneidrad (Schneidewerkzeug) über eine öffnung hinweg bewegt.c) a permeable vacuum coating connected to the carrier to cover the apertures, the coating being selected to sufficiently hold the sheet material when covering an aperture to enable cutting of the sheet material as the cutting wheel (cutting tool) moves across an aperture.
