摘要： A cross flow knife coater includes a coating station through which a surface passes and a trough which extends transversely across the desired width of the coating. The trough has an opening through which coating fluid exits onto the surface without using a slot, and first and second transverse ends. The coating fluid is fed directly into the trough at a first transverse end, and is moved from the first transverse end of the trough, across the trough, and toward the second transverse end to cause the coating fluid to flow across the width of the trough while coating fluid exits the opening. The coater creates a spiral flow of coating fluid across the width of the trough which carries debris, bubbles, and other undesirables across the trough to a second traverse end where they can be vented. The perpendicular distance between the trough opening and the surface, and likewise between the knife and the surface, can be adjusted.

摘要： A coating insert used within a coating assembly for defining at least one edge of coating fluid as it is applied to a substrate moving past the coating assembly is disclosed. The coating assembly includes a trough having first and second transverse ends. At least one coating insert is inserted within the trough to define an edge of coated fluid on a substrate. The coating insert, having one or two edge-defining surfaces, is positioned within the trough. The first end of the edge-defining surface is closer to the adjacent transverse end of the trough than the second end of the edge-defining surface. The top face of the coating insert may also include a second edge-defining surface having first and second ends that may define another edge of coated fluid on a substrate.

摘要： Screen-printable acrylate pressure-sensitive adhesive composition suitable for adhesive products having simultaneously, and independently from temperature, high values of adhesion, peel strength and shear strength as well as a high water and humidity resistance, comprising(A) about 25 to 225 parts by weight of at least one dissolved inherently tacky pressure-sensitive adhesive selected from non-crosslinked (meth)acrylic ester/(meth)acrylic acid copolymers having an average molecular weight corresponding to an inherent viscosity of not more than 1.0 dl/g; and(B) 100 parts by weight of an organic solvent or solvent mixture having a low partial vapor pressure of less than about 3 kPa (30 mbar) at 20.degree. C. and a dipole amount of at least 1.0 Debye. The acrylate copolymer preferably has structural units of the formula ##STR1## wherein R.sup.1 and R.sup.2 independently are hydrogen or lower alkyl having 1 to 4 carbon atoms; R.sup.3 is hydrogen, a lower alkyl group having 1 to 4 carbon atoms and a cyano group; and R.sup.4 is hydrogen or an alkyl group having 1 to 14 carbon atoms, n is the average degree of polymerization, subject to R.sup.4 being a hydrogen atom in at least 5 weight % of the total monomer units, one of groups R.sup.1 and R.sup.2 optionally being carboxyl of the formula --C(.dbd.O)--OR.sup.4 and R.sup.3 optionally being a methylene carboxyl group having the formula --CH.sub.2 --C(.dbd.O)--OR.sup.4.
