Abstract:
A binding processing apparatus includes: a pressure-applying member pair that has multiple projections arranged side-by-side and applies pressure to a sheet stack by pressing the projections against the sheet stack; and an advancing-and-retracting part that causes at least one of the pressure-applying members in the pressure-applying member pair to move toward or away from the other pressure-applying member. A pitch of the projections in each pressure-applying member is from 1.2 mm to 1.5 mm, and a height of the projections is from 0.55 mm to 0.75 mm, and a load per unit area applied from each pressure-applying member to the sheet stack when the pressure-applying member applies pressure to the sheet stack is from 42 N/mm2 to 94 N/mm2.
Abstract:
Deformed web materials are disclosed. The web materials have discrete deformations formed therein. The deformations may be features in the form of portions of a web with apertures therein, protrusions, depressed areas, and combinations thereof. These features may extend out from the surface on one side of the web, or from both of the surfaces of the web. Different features may be intermixed with one another.
Abstract:
An embossing method and apparatus utilizes 3D printing by digitally dispensing\ink jet printing to apply texturing features to a work roll or a sheet that may be fed into a rolling mill to emboss sheet material like aluminum alloy sheet. The printed pattern is highly variable and may be produced quickly and easily allowing low volume embossing. The printed pattern may be removed from a work roll after use to allow the roll to be reused. Alternatively, a sheet receives the printed pattern, is rolled and then the printed material removed from the resultant depression.
Abstract:
A sheet processing apparatus includes a binding portion binding a plurality of sheets stacked on a sheet stacking portion as a bundle by deforming the sheets without a staple. The sheet processing apparatus further includes a moving member moving the sheet bundle bound at a binding position by the binding portion from the binding position and a restricting member restricting the move of the sheet bundle such that a distance between the sheet bundle and the moving member is kept to be less than a predetermined distance in moving the sheet bundle by the moving member.
Abstract:
An apparatus for embossing a web substrate is disclosed. The apparatus has a pattern roll, at least two rolls juxtaposed in an axially parallel relationship with the pattern roll, and a continuous belt disposed about the at least two rolls. The pattern roll has a circumference and an embossing pattern disposed upon a surface thereof. The continuous belt is capable of providing a compressive force to the surface of the pattern roll and has a circumferential axis generally corresponding to the surface of the pattern roll. The continuous belt is disposed proximate to at least a portion of the circumference of the pattern roll and forms a circumferentially elongate nip therebetween. The pattern roll and the continuous belt are adapted to receive the web substrate at the elongate nip.
Abstract:
An apparatus for embossing a web substrate is disclosed. The apparatus has a pattern roll, at least two axially parallel juxtaposed rolls, a continuous belt disposed about the rolls, and a pressure assist device. The pattern roll has a circumference and an embossing pattern disposed upon a surface thereof. The continuous belt has first and second surfaces and circumferential axis and is disposed upon at least a portion of the circumference of the pattern roll forming a circumferentially elongate nip therebetween. The pressure assist device is disposed proximate to the second surface of the continuous belt and is adjustable relative to at least one of the second surface of the continuous belt and the surface of the pattern roll.
Abstract:
An apparatus suitable for use with a web substrate embossing system is disclosed. The apparatus comprises at least two rolls juxtaposed in an axially parallel relationship and a continuous belt capable of providing a compressive force to a corresponding embossing surface. The continuous belt is disposed about the at least two rolls. The at least two rolls and continuous belt have an axis generally corresponding to the corresponding embossing surface. A first surface of the continuous belt is capable of being disposed proximate to at least a portion of the corresponding embossing surface and forming an elongate nip therebetween.
Abstract:
A flexible die is used in an embossing apparatus in which a pair of flexible bases (2a, 2b) are respectively wrapped around a pair of cylindrical rollers disposed opposing each other, and a sheet to be processed (S) is passed through between the pair of rollers, thereby performing embossing. The pair of flexible bases (2a, 2b) are constituted by a female flexible base (2a) and a male flexible base (2b) that are mated with each other, a line-shaped convex portion (3a) corresponding to the contour of an embossing processing pattern is formed in the female flexible base (2a), and the convex portion (3b) is formed in the male flexible base (2b), the convex portion (3b) being fitted within the area encompassed within the line-shaped convex portion (3a) of the female flexible base while leaving an interval from the inner circumferential surface of the line-shaped convex portion (3a). A concave portion (30) is formed in the convex portion (3b).
Abstract:
Sheet-like materials suitable for use in the containment and protection of various items, as well as the preservation of perishable materials such as food items, comprise a sheet of material having a first active side and a second side. The first active side comprises a plurality of three-dimensional non-adherent protrusions extending outwardly from surrounding depressions and a pressure-sensitive adhesive composition coating on at least a portion of the depressions, wherein the adhesive composition coating has a thickness less than the height of the non-adherent protrusions and from about 0.00001 (0.00025 mm) to about 0.0002 inches (0.0051 mm) in thickness.
