The lubrication device delivers a lubricant to the perforating device which provides intermittently spaced cuts to a moving web, also referred to as perforations. The lubrication device includes a retaining member, a plenum, and a comb having a plurality of comb channels. The plenum and the plurality of comb channels are in fluid communication with one another and deliver a lubricant to the perforating device. Lubrication of the perforating device in this manner may improve knife life, perforation quality and web handling.

Perforator lubrication system

The present invention provides a method of producing a decorative tissue product, while controlling tensile degradation in a predicable fashion. The foregoing properties may be achieved using differential depth embossing in conjunction with an embossing pattern having particular characteristics. The use of an engraved roll, such as an embossing roll, having protuberances of differing depths and patterns not only improves the properties and characteristics of the fibrous structure, but may also be used to impart a unique pattern that provides the product with a distinctive look and is appealing to consumers. Generally the unique pattern results from a first set of protuberances having a first height and defining a first pattern and a second set of embossing elements having a second height and defining a second pattern, where the first height is greater than the second height.

Embossed multi-ply tissue product

Rolled tissue product

The present invention provides a perforating station comprising two or more discrete perforating stations, the stations synchronized with one another to cut a line of perforations across a web, such as a web of tissue paper, moving at high speeds. By providing two or more synchronized perforating stations the perforating station may increase the number of impacts per minute compared to prior art perforating devices.

Multilateral cutter

An apparatus for perforating sheet materials is disclosed. The apparatus includes a perforation blade that defines a plurality of teeth for perforating sheet materials, such as tissue products. Each tooth on the perforation blade is defined by a pair of opposing side walls. The teeth are separated along an edge of the perforation blade by a plurality of recesses. In accordance with the present disclosure, the side walls have a non-zero angle with respect to the length direction of the blade. In one embodiment, each recess can have a slanted U-shape such that all of the side walls are parallel. In an alternative embodiment, the recesses can have a V-shape such that adjacent side walls extend in divergent directions. Perforation blades made according to the present disclosure prevent snagging and picking when a material is perforated.

Perforation blade for perforating tissue products

Curvilinear or other complex perforation patterns for paper products, such as paper towels and bath tissue, can be produced using a differential speed perforation nip formed between a rotating pattern roll and a moving anvil surface. The relative speed between the perforation elements on the surface of the pattern roll and the anvil surface shears the web at the perforation points.

Method for perforating tissue sheets

Coreless tissue rolls can be produced without having to use an adhesive to form a hollow center. Instead, moisture can be used to promote light hydrogen bonding between the layers of the tissue web that line the hollow center. The hydrogen bonding provides sufficient structure to maintain the shape of the hollow center without rendering the tissue web surrounding the passageway unusable. Passageways can also be formed in accordance with the present disclosure that are substantially circular so that the rolls will easily spin on a spindle. In an alternative embodiment, moisture is not used in constructing the wound tissue roll.

Coreless tissue rolls and method of making the same

Tissue paper with embossing pattern

Coreless rolls of tissue, such as rolls of bath tissue or paper towels, are produced by winding tissue logs on a mandrel having retractable pins. During winding, the pins extend and penetrate the first several windings of the log as it is initially wound, which prevents slippage. After the winding is complete, the pins retract to allow the tissue log to slide off of the mandrel for subsequent slitting into individual product rolls and packaging. The penetration of the pins into the first several windings of the log tends to mechanically entangle and structurally unify those windings to create a 'soft core'. At the same time, the properties of the tissue sheets within the soft core are the same as the other sheets within the roll and are therefore usable by the consumer.

Coreless tissue rolls

A winder for winding a web to produce a rolled product is provided. The winder includes a web transport apparatus that is used for conveying the web. Also included in one exemplary embodiment is a plurality of independent winding modules. The winding modules are independently positioned to independently engage the web as the web is conveyed by the web transport apparatus. The winding modules may be configured to wind the web to form a rolled product by center winding, surface winding, and combinations of center and surface winding. The winding modules are structurally and operationally independent of one another where if one module is disabled, another may still operate to produce the rolled product without shutting down the winder.

Center/surface rewinder and winder

A system and process for aligning printed images on a rolled product with perforation lines being formed into the product is disclosed. According to the process, the position of printed images are sensed as the images are being printed onto a substrate, such as a tissue strip. The images are printed onto the substrate using a printing device including at least one rotating print roller. In order to maintain the printed images in alignment with perforation lines being formed into the substrate, the speed of the print roller is adjusted in order to adjust the length of the printed images.
