Abstract: Heat resistant separation fabric consisting out of yarns, wherein the yarns comprise metal fibers; wherein the heat resistant fabric comprises boron nitride particles distributed throughout the complete thickness of the fabric; wherein boron nitride particles are present between metal fibers in the yarns; wherein the amount of the boron nitride particles present on the surface of the fabric is not more than the amount of the boron nitride particles present in the bulk of the fabric.

Abstract: The heat resistant separation fabric for use as tool cover in glass processing comprises heat resistant yarns (100). The heat resistant yarns comprise a core (110) and at least one wrap yarn (123, 125). The core is a core yarn. The core yarn is a multifilament glass yarn. The at least one wrap yarns (123, 125) comprises stainless steel fibers. The core yarn is present in the heat resistant yarn without crimp. The at least one wrap yarn is wrapped around the core yarn.

Abstract: A heat resistant separation fabric for use as tool covering in the production of glass products at temperatures over 580° C., wherein the heat resistant separation fabric comprises fiber yarns, and wherein said fiber yarns comprise metal fibers out of first material containing: 18 to 21 weight percent Cr, 23 to 26 weight percent Ni, 5.5 to 7 weight percent Mo, and 40 to 50 weight percent Fe.

Abstract: A warp knitted heat resistant separation fabric is provided, having at least two sets of warp yarns. A first set of warp yarns is positioned over the width of the fabric and formed with pillar stitches; and a second set of warp yarns positioned over the width of the fabric shows in its repeat in the fabric an underlap under at least two pillars that are formed by the first set of warp yarns.

Abstract: A knitted fabric made from yarn comprising fibers. At least part of these are metal fibers. The yarn comprises at least 3 bundles or single yarns. The bundles or single yarns have an equivalent bundle diameter which are equal or differ maximally 40%. The fabric is used as a separation cloth (12) between mold (11) and glass (14), which is utilized in the process of forming glass plates, or for covering of press-on rings or press-rings and the means of transport by which glass plates are moved during the forming process. The use of yarns composed of least 3 bundles which more or less have the same equivalent bundle diameter reduces the risks for markings on the glass.

Abstract: A heat resistant separation fabric including stainless steel fibers. The stainless steel fibers are made out of an alloy comprising more than 12% by weight of chromium. The stainless steel fibers include an oxide skin. The atomic percentage of Cr at 5 nm depth of the oxide skin divided by the sum of the atomic percentages of Cr and Fe at 5 nm depth of the oxide skin, and multiplied with 100 to express as a percentage, is higher than 30%.

Abstract: A fabric (30) is adapted for covering at least partially a ring for quenching glass which has been bent. The fabric (30) comprises at least three strips (32, 34, 36): a strip (32) of a high-density knitted structure for quenching the glass and two strips (34, 36) of a lower density structure for attaching the fabric (30) to the ring.
