In a method for external lubrication of the press rolls (2 or 2.1) of a roller compaction device (1) by means of a continuous coating of said press rolls (2 or 2.1), a thin layer of a lubricant and/or an anti-adhesive are continuously provided to coat the press rolls (2 or 2.1). This coating preferably contains magnesium stearate or a mixture containing magnesium stearate. To carry out the method, at least one coating device (13, 14, 15 or 13.1, 14.1, 15.1) is arranged in a housing in which the press rolls (2 and 2.1) are arranged, by means of which coating device at least one press roll is provided with a thin coating of a lubricant and/or an anti-adhesive, preferably with magnesium stearate or a mixture containing magnesium stearate. The method is used for the manufacture of dry granules in the pharmaceutical and food industries.

Methods for creating multi-layered incrementally-stretched and incrementally-laminated bags with increased or maintained strength are described herein. An increased level of strength is achieved by bonding adjacent layers of a multi-layer film together in a manner that the bond strength of the laminated layers is less than a strength of a weakest tear resistance of the individual first and second film layers. The inventors have surprisingly found that such a configuration of light bonding provides increased and unexpected strength properties to the multi-layer film as compared to a monolayer film of equal thickness or a multi-layer film in which the plurality of layers are tightly bonded together.

Systems and methods for texturing substrates (e.g., glass, metal, and the like) and the textured substrates produced using such systems and methods are disclosed. An exemplary system for texturing a substrate includes a first roller and a second roller. The first roller has a first textured surface. The first textured surface has a root mean square roughness between 40 to 1000 microns and an autocorrelation function greater than 0.5 for distances less than 50 microns.
