Abstract:
An apparatus for sequentially forming a plurality of generally longitudinally extending grooves in the peripheral surface of a filter rod includes a rotatable drum having a plurality of filter rod receiving channels formed in its outer peripheral surface for receiving filter rods to be grooved. The device includes filter rod indexing devices which engage the filter rods in the receiving channels. As the drum rotates about its central axis, the filter rod indexing devices are individually and selectively activated to incrementally rotate selected filter rods about their longitudinal axes through an angle corresponding to the angular spacing between adjacent grooves to be formed in the peripheral surface of the filter rod. A plurality of groove forming rollers are located at selected positions at the periphery of the drum. The rollers each have a plurality of groove forming blades projecting radially outwardly therefrom. A groove forming blade in sequentially positioned rollers sequentially form a groove in the filter rod after the filter rod has been rotated about its longitudinal axes from the position of a previously formed groove by the filter rod indexing device.
Abstract:
A sheet binding device includes a pressurizing unit that pressurizes a sheet bundle to bind the sheet bundle, a pressurizing section that is disposed in the pressurizing unit and configured to be moved from a waiting position separated from the sheet bundle to a pressurizing position at which the pressurizing section pressurizes the sheet bundle, a drive motor that actuates the pressurizing unit, and a controller that controls the drive motor such that the pressurizing section is engaged with the sheet bundle at a predetermined setting velocity.
Abstract:
An embossing system for embossing at least a portion of a web is provided comprising a first embossing roll having male embossing elements, a second embossing roll having male embossing elements, wherein the first and second embossing rolls define a first nip for receiving the web, and a third embossing roll having male embossing elements, wherein the second and third embossing rolls define a second nip for receiving the web, and wherein at least a substantial portion of the embossing elements of at least one of the first, second, and third embossing rolls are substantially oriented in the cross-machine direction.
Abstract:
An embossing system is provided for embossing at least a portion of a web comprising a first roll and at least a second roll. The first roll and second roll may define a first nip for embossing the web. At least one of the first roll and the second roll has elongated embossing elements extending substantially in the machine direction and optionally at least one of the first and second rolls has elongated embossing elements extending substantially in the cross-machine direction. At least one of the first roll and the second roll may also have perforate embossing elements extending substantially in the cross-machine direction that may or may not be elongated. The embossing elements are capable of imparting one or both of a cube embossing pattern or a perforate emboss on the web. The web may be a cellulosic fibrous web, a portion of which is lignin-rich, high coarseness fiber having generally tubular fiber configuration. In addition, the web may be creped with an undulatory creping blade.
Abstract:
In the method for the authentication of identification features that are embossed on a packaging foil together with satin-finishing and the embossing of logos, a number of identification features is embossed on-line as a pattern and read by a suitable apparatus and evaluated by means of an image evaluation method.The embossing device (1) suitable therefor includes at least two embossing rollers (2, 3, 15), a reading unit, and an evaluating unit, one of the embossing rollers (2) being driven by the motor drive mechanism (5) and having individual teeth (8) of which a number of teeth for embossing identification features have a different shape, height, or surface structure while the remaining teeth serve for satin-finishing, and one of the mating rollers (3) being provided with circumferential rings (10).Such a method and such a device allow a relatively simpler embossing device with relatively lower requirements with regard to the embossing quality than in methods of the prior art.
Abstract:
An apparatus for embossing a web substrate is disclosed. The apparatus has a pattern roll having an embossing pattern disposed thereon, an anvil roll juxtaposed in an axially parallel relationship with the pattern roll, and an embossing roll juxtaposed in an axially parallel relationship with said pattern roll. The anvil roll has a hardness of less than about 40 P&J. The embossing roll has a hardness of greater than about 40 P&J.
Abstract:
An apparatus for embossing a web substrate is disclosed. The apparatus has first, second, and third pattern rolls. The first, second, and third patterns rolls each have respective first, second, and third pluralities of raised elements and recesses disposed thereon. A first nip is formed between the first and second pattern rolls and a third nip is formed between the first and third pattern rolls. The raised elements and the recesses of the first pattern roll are matingly engagable with the corresponding plurality of raised elements and recesses of the corresponding second and third pattern rolls. The first and second nips are both adapted to receive the web substrate and emboss the web substrate with the respective and corresponding embossing patterns when the web substrate is disposed within the respective nip.
Abstract:
A process for embossing a web substrate is disclosed. The process comprises the steps of: 1. disposing the web substrate in a circumferentially elongate nip formed between a pattern roll having a circumference and an embossing pattern disposed upon a surface thereof and a continuous belt disposed about at least a portion of the circumference of the pattern roll; 2. providing the continuous belt with a surface speed corresponding to a speed of the web substrate; and, 3. juxtaposing the embossing pattern upon the web substrate while the web substrate is disposed within the elongate nip.
