Abstract: The invention provides an aqueous binder for granular and/or fibrous substrates, said binder comprising, as active constituents, a polyamine and a saccharide compound.

Abstract: Aqueous binder composition for granular and/or fibrous substrates, where the binder contains i) a copolymer constructed from ethylenically unsaturated monomers; and ii) lignin.

Abstract: A device is provided to shape a spine of a book casing positioned horizontally spread out flat and oriented to be distributed evenly over a spine of a book block. Two fold-shaping rails are arranged extending in a direction parallel to one another. A movable, shaping tool is arranged to face the inside of the book casing spine to shape a web on the book casing spine with the aid of the two fold-shaping rails. The shaping tool includes two spaced-apart support bars that extend parallel to the fold-shaping rails and are arranged to be adjustable so that together they adjust the web width of the book casing spine in a direction transverse to the direction of extension of the fold-shaping rails.

Abstract: A device for forming the outstretched, horizontally positioned spine of the case of a book, which is extended uniformly over, and aligned with, the spine of a book block, and which possibly has an inlay such as schrenz paper. The device includes a forming tool, which can be moved toward the inside surface of the spine of the case, i.e., the surface which faces the spine of the book block, lifts the case spine up between two lateral, opposing creasing rails, and produces at least a rounded or flat web on the spine between the book covers of the case. The forming tool is mounted on a rotatable frame having an axis of rotation which is parallel to the creasing rails.

Abstract: A device for deforming a book back cover aligned approximately uniformly distributed on a book back, possibly a book cover back having a back insert of a horizontally stretched out positionable book cover, composed of a deforming saddle which can be pushed forward onto the downwardly directed inner side of the book cover, wherein the book cover back is producing a rounded portion of the round cover back located opposite the folding rails between two laterally opposing fold shaping rails which produce a rounded portion of the book cover back, wherein the deforming saddle is formed by two laterally downwardly directed saddle blades formed by the saddle blades which lift the book cover back during the deformation, wherein for adjusting the rounding of the book cover back the saddle blades are together pivotably constructed about an axis extending parallel to the book cover back.

Abstract: A ply has a base weight of not more than 45 g/m2 for use in a ceiling element and includes a fiber blend in a proportion of not more than 30 g/m2 a flame retardant in a proportion of not more than 10 g/m2.

Abstract: A layer, in particular for use as a separator in galvanic cells, including fibers having at least one first substance which renders possible the chemical and/or physical binding of ammonia or ammonia compounds. A galvanic cell having a low self-discharging rate over its entire life cycle having a layer wherein a first substance is present in volumetric regions of the fibers whose surface areas are at least partially covered by a second substance.

Abstract: A nonwoven fabric, in particular for use as a separator in batteries or galvanic cells, having functional fibers made of at least one fibrous material which intrinsically contains at least one substance that is chemically active or activatable in an alkaline medium. The substance is incorporated surface-actively exclusively in volumetric regions of the functional fibers whose surface areas are able to be acted upon by the medium. A fiber is made from the mentioned fibrous material. A galvanic cell contains this nonwoven fabric as a separator.

Abstract: A nonwoven fabric for manufacturing repeatedly re-usable clean-room protective clothing, made of super microfilaments having a titer of less the 0.2 dtex that are produced by water jet splitting multicomponent multisegment filaments having a titer of less than 2 dtex, the primary filaments being spun from the melt, aerodynamically stretched, laid to form a nonwoven fabric, and subjected to water-jet prebonding prior to splitting.
