DRY PAPER MACHINE

In a dry paper machine, in the step following the forming section, the fiber web has been conducted with the aid of topside and/or underside wires through the machine to the purpose of adding, drying and polymerizing the bonding agent. The unbonded fiber web has low strength and requires careful handling so that it might not break and cause process shut-downs. This circumstance has in modern paper machines resulted in a running speed which is low compared with the theoretical capacity of the machines. It has been found that web breaks tend to occur at the so-called open draws of its carry-through path, where the fiber web is not supported and is allowed to hang free in the air or carried by a wire (2, 3, 9). The object of the invention is to avoid open draws and to convey the web (1) in supported fashion through the entire process. The reliability of the procedure is improved by placing the mechanically drying calendering to be the last treatment step before polymerizing.

Methods of applying bonding materials onto fibrous webs

Methods by which a dry-formed loose fibrous web is bonded by applying to one of its surfaces a low add-on level of a relatively high binder solids concentration bonding material to form a once-bonded web, and to the other side of the web, a greater add-on level of a relatively lower solids concentration bonding material, the first-applied emulsion preferably adding from about 20% to about 40% binder solids by weight, and the second-applied adding the rest of the total binder solids to be included in the fibrous web product. The bonding material can be a solution or emulsion. Preferably, the first and second-applied bonding materials are water-based latex emulsions, the solids concentration of the first-applied emulsion is from about 15% to about 25% by weight, that of the second-applied emulsion is from about 10% to about 20% by weight based on the total binder solids to be included in the fibrous web product, and a vacuum draws the second-applied bonding material into the web.

System and method for producing a facing for a board product with strategocally placed scores

A system and method for producing a board product made from paper products that have a pre-scored facing in addition to a medium (sometimes called fluting). Conventional corrugated board may feature a cross-corrugated medium and one or more facing that have no score lines that are impressed (at least prior to assembly with the corrugated medium). Such a conventional board product may be inferior because any score lines that are impressed will damage the underlying corrugated medium in some manner. A breakdown in the strength of the underlying medium leads to poor precision when the eventual board product is scored, cut, and folded. A lack of precision in folding a board product leads to gap variation and fishtailing as any articulated portion of the board product may not maintain a precise plane of articulation when folded.

Process for increasing the basis weight of sheet materials

Sheet-like products are disclosed containing an additive composition. In accordance with the present disclosure, the additive composition is applied to a creping surface. The additive composition includes at least an aqueous dispersion containing a thermoplastic polymer. A base sheet is then pressed against the creping surface for contact with the additive composition. The base sheet is then creped from the creping surface causing the additive composition to transfer to the base sheet. In particular, the additive composition is transferred to the base sheet in amounts greater than about 1% by weight, such as from about 2% to about 50% by weight. The additive composition may further include a lotion, a debonder, a softener, or mixtures thereof.

Soft tissue

Cloth-like base sheet and method for making the same

An improved cloth-like base web is disclosed. In particular, the base web of the present invention has a cloth-like look and feel and has improved absorbency. The base web is made by first hydroneedling a web containing pulp and/or staple fibers. A bonding material is then applied to at least one side of the web and the web is creped on at least one side. By combining a hydroneedling operation with a creping operation, a base web is produced that is strong, stretchable, very soft and absorbent.
