Abstract:
A method for embossing products with a rotary embossing device includes controlling the rotation of at least one embossing roller as a function of marks that are present on the products and are detected by sensors. A folder gluer having a rotary embossing device is also provided.
Abstract:
A plant for the production of embossed articles is disclosed. Upstream of the embossing group for the plant and add on a glue dispensing unit and/or a printing unit having a cliché roll for the application of the glue on a web of band or ink on the band is provided. The web or the band moves between the cliché roll and a contrast cylinder. Actuator means are provided for approaching or moving away a portion of the cliché roll from the contrast cylinder. Thus, regardless of the type of paper used, it is possible to obtain a perfect adhesion of the webs without jeopardizing the softness of the paper used. It is also possible to obtain the printing in selected areas of the product being processed.
Abstract:
A sheet processing apparatus includes a binding unit configured to perform binding processing by pressing a sheet bundle, a motor configured to drive the binding unit to press the sheet bundle, a speed detection unit configured to detect a speed of the motor, a voltage detection unit configured to detect a driving voltage of the motor, and a motor control unit configured to determine an upper limit value of a driving current of the motor based on the speed detected by the speed detection unit and the driving voltage detected by the voltage detection unit in a period when the motor is being driven and the binding unit is not pressing the sheet bundle.
Abstract:
The device for embossing and perforating foils for tobacco goods includes: a pair of embossing rolls, one of the embossing rolls having teeth for perforating the foil, the counter roll to the embossing roll with the perforating teeth being a matrix roll which has recesses that correspond to the teeth on the patrix roll, both embossing rolls being arranged in a perforation device, and the device being designed in order to be operated directly or indirectly online in a machine for producing tobacco goods. The use of patrix-matrix embossing rolls allows for a large variety of perforations, the device having a control unit designed to control the exact position, size and arrangement of the perforations on the basis of the quality of the foil to be processed.
Abstract:
Apparatus and method for checking the depth of a crease line in a material comprising a stamping device (4) having stamping portions (8) arranged at a plurality of levels with respect to a surface of said material, the arrangement being such that those portions (8) which contact the material mark the material with an indicator indicative of the depth of the crease line.
Abstract:
A device (1) for embossing a predetermined pattern onto at least one flat material (4) introduced between at least two printing rollers of said device, the movements of the embossing rollers being synchronized and said rollers (2, 3) also comprise at least two embossing tracks (5, 6), wherein the movements of the embossing rollers (2, 3) are synchronized with each other by synchronization means (7, 8) associated with different embossing tracks (5, 6), which mesh with each other and are distributed over the lateral surfaces of the embossing rollers (2, 3) or are electronically and/or electromechanically synchronized together, the different embossing tracks (5, 6) of the associated synchronization means (7, 8) of the same embossing roller (2, 3) being offset in relation to each other.
Abstract:
Method and apparatus for manufacturing a hygiene paper product includes: providing a continuous paper web, moving the continuous web in the direction of its longitudinal extension, applying a repetitive creative structure relative to the longitudinal extension of the web as a first pattern to the web with a first roll, applying a repetitive functional structure relative to the longitudinal extension of the web as a second pattern to the web with a second roll, while enabling the first pattern to be in register with the second pattern by concurrently controlling the repetitive surface speed of continuous web and the phasing between the first roll and the second roll.
Abstract:
A method of embossing an absorbent web with a machine direction undulatory structure is described. The web has a plurality of ridges extending in its machine direction occurring at a frequency, F, across the web and the method includes providing the web to an embossing station where the web is embossed between a first and second embossing roll, each of which rolls may be provided with a plurality of embossing elements configured to define a plurality of embossing nips. At least a portion of the embossing nips are substantially oriented in a cross-machine direction with respect to the web and have a cross direction length, L. The product F×L is from about 0.1 to about 5.
