A method of increasing the density and reducing the bulk of multi-ply paper products allowing one to reduce the roll size or increase the roll content, while minimizing the destruction of favorable product attributes.

A creasing device includes a frame with a substantially horizontal support surface for supporting an article to be creased; a movable tool; and a stationary tool, the latter comprising a stationary member and at least one displaceable member whose height relative to the stationary member can be adjusted. A first actuator moves the movable tool toward the stationary tool and interacts with opposite faces of the article, and a second actuator translates the displaceable member between a first end position in which interacts with the movable tool and a second end position in which it cannot interact with the movable tool. Guide means associated with the stationary tool guides the displaceable member between the first end position and the second end position. The guide means are have a curvilinear path contained in a plane substantially perpendicular to the support surface.

In an apparatus for raising chickens from hatchlings including a barn having a floor and walls there is provided a plurality of rows of feed stations arranged at spaced positions across the floor each with a feed supply line connected along the row for dispensing feed to each of the feed stations and a plurality of rows of water supply stations each with a water supply line connected along the row for dispensing water to each of the water supply stations where rows of stations are connected to a lift system for raising the stations from the floor. A first strip of biodegradable paper sheet is unrolled along the floor of the barn underneath the row of feed stations and a second strip of biodegradable paper sheet unrolled along the floor of the barn underneath the row of water supply stations where the biodegradable paper is colored with a color selected to be attractive to hatchlings, typically red.

A method of increasing the density and reducing the bulk of multi-ply paper products allowing one to reduce the roll size or increase the roll content, while minimizing the destruction of favorable product attributes.

The embossing device includesa first path for a first ply of web material; along the first path, a first embossing roller provided with embossing protrusions; a first heating device associated with the first embossing roller to heat the surface of the first embossing roller; at least a first functional roller adapted to perform an action on a ply of web material. The first functional roller is provided with a rotation arrangement, adapted to keep the first functional roller in rotation during a temporary stoppage of the embossing device, with the first functional roller spaced from the first embossing roller and with the first ply of web material stationary in the first path.

A method of increasing the density and reducing the bulk of multi-ply paper products allowing one to reduce the roll size or increase the roll content, while minimizing the destruction of favorable product attributes.

A machine for embossing, including at least one pair of embossing nips for plies of paper, at least one laminating nip to bond the plies of paper, a pair of embossing cylinders, each having on its surface a respective plurality of embossing protrusions, each defining a wrap angle for the at least one ply of paper, and defining therebetween a transfer nip, a pair of pressure cylinders, each associated with a respective one of the embossing cylinder, the embossing nip being defined between each pair formed of embossing cylinder and pressure cylinder, a laminating device for bonding the plies delivered from the transfer nip, at least one distribution device of material to facilitate ply-bonding arranged upstream of the laminating device, and at least one heating device for at least one of the embossing cylinders.

The embosser includes two load-bearing structures that are mutually movable to approach and move away from each other. The first load-bearing structure supports a plurality of first embossing rollers that can be selectively brought to an operating position, in which they cooperate with a first pressure roller. The second load-bearing structure supports one or more second embossing rollers cooperating with a second pressure roller. The two support structures can be moved away from each other to allow the selection movement of the first embossing rollers.

Disclosed are embossed, multi-ply tissue products having consumer preferred physical properties and an aesthetically pleasing appearance. The products may have a first ply embossed with a first pattern comprising line emboss elements and a second ply embossed with a second embossing pattern comprising dot emboss elements. In addition to having plies with different embossing patterns, the plies may have different tensile strength, such as a first ply having a geometric mean tensile (GMT) strength greater than 500 g/3 and a second ply having a GMT less than 500 g/3. Preferably the difference in the GMT between the first and second plies is at least about 20 percent, such as from about 20 to about 50 percent.

According to an aspect of the invention, a binding device includes a first rotary member including a first serrated portion on its circumferential surface, a second rotary member including, on its circumferential surface, a second serrated portion to be engaged with the first serrated portion at an engaging position and configured to perform a binding process by rotating together with the first rotary member with a bundle of sheets pinched therebetween to form serrations in the sheet bundle in thickness direction and bring the sheets into engagement with each other while relatively moving the sheet bundle in a predetermined moving direction, and a clamping unit configured to, when the binding process is performed, clamp the sheet bundle at a clamping position upstream of the engaging position to apply a predetermined pulling force acting in a direction opposite to the moving direction to the sheet bundle.
