Systems and methods for pressing a door assembly involve one or more die sections installed in a press, wherein the die sections each have a raised section that contacts and supports a recessed panel portion of a door skin of the assembly during the pressing operation to facilitate crushing of portions of a core of the door assembly that underlie the recessed panel portion of the door skin. The die sections may be made of plastic and readily changed out for different sizes or styles of doors.

A cellulose fiber-based substrate, at least one side of which is coated with an aqueous mixture composed of: a) at least one water-soluble polymer (WSP) containing hydroxyl groups, b) at least one lactone substituted with at least one linear or branched and/or cyclic C.sub.8-C.sub.30 hydrocarbon chain which may contain heteroatoms, c) at least one crosslinking agent. A method of production and use thereof.

A filter medium for filtration of a gaseous medium is provided with a carded nonwoven layer and a filter paper layer arranged as a neighboring filter layer at an outflow side of the carded nonwoven layer. The carded nonwoven layer has a first air permeability and the filter paper layer has a second air permeability, wherein the first air permeability of the carded nonwoven layer is higher than the second air permeability of the filter paper layer. In a filter element with such a filter medium, the filter medium is folded to a folded filter medium with folds with a fold spacing of more than 3.5 mm and a fold height of between 10 mm to 60 mm.

A sheet structure, fabricated from paper and/or paperboard material, provides a thickness dimension ordinarily associated with corrugated paperboard material. The sheet structure is constructed from a first planar linerboard sheet and a second non-planar linerboard sheet, wherein a plurality of projections are cut and folded from the second linerboard sheet and are adhesively coupled to the first linerboard sheet, such that portions of the projections define a standoff between the first and second linerboard sheets.

The cellulose product comprises at least a first ply of embossed cellulose material and a second ply of embossed cellulose material, glued together. The first ply comprises: a first series of embossing protuberances with a first height (H1) and a top surface to which a glue is applied which bonds the first ply and the second ply to one another; a second series of micro-embossing protuberances with a second height (H2) lower than the first height (H1); a third series of micro-embossing protuberances with a third height (H3) lower than the second height (H2). The protuberances of the first series are distributed over areas of the first ply, where the micro-embossing protuberances of the second series and the micro-embossing protuberances of the third series are absent.

There is described a method of creating a transparent polymer window (W) with a field of lenses (L) in a security paper substrate (1), the method comprising the steps of (i) providing a security paper substrate (1), (ii) forming an opening (10) into the security paper substrate (1), (iii) laminating a transparent film (5; 5*) onto a first side (I) of the security paper substrate (1) in such a way as to close the opening (10) at one end, and (iv) filling the opening (10) with transparent polymer material (2). In one embodiment, the transparent film (5) comprises a field of lenses (L) and is laminated onto the first side (I) of the security paper substrate (1) in such a way as to form lenses (L) on the first side (I) of the security paper substrate (1) in register with the opening (10). In another embodiment, the field of lenses (L) is replicated into the transparent polymer material (2) applied in the opening (10) in such a way as to form lenses (L) on a second side (II) of the security paper substrate (1), opposite to the first side (I), in register with the opening (10). Also described is a device designed to fill the opening (10) formed into the security paper substrate (1) with the transparent polymer material (2) and a processing machine comprising the same.

Products having improved ply bonding, moldability and drape and methods for making those products are described. The methods comprise producing a multi-ply adhesively bonded product comprising a pattern of uniformly spaced microembossed elements with a bond area of less than about 0.020 inches/sq. inch.

The present invention relates to a system and method for the production of gypsum board using starch pellets. In accordance with the present disclosure, the starch necessary for board formation is provided in the form of starch pellets. These pellets are mixed with a gypsum slurry in a mixer. The pellets are initially insoluble and do not dissolve. However, during subsequent drying stages, the pellets become soluble and dissolve into the gypsum phase. This both provides the desired starch component and also results in the formation of voids within the set gypsum.
