The present invention relates to a machine for the production of a component for an aerosol generating article, the machine including: a buffer station, the buffer station including: # fixed sheet guides; # movable sheet guides which are movable in a reciprocating manner in a direction towards the fixed sheet guides and in a direction away from the sheet fixed guides; # an actuator for moving the movable sheet guides, wherein the fixed and movable sheet guides together define a zig-zag trajectory for the sheet having a variable length for varying the total length of the sheet of material in the buffer station; # supports for the sheet, the supports being arranged so that, when the movable sheet guides are moved towards the fixed sheet guides, at least one of the movable sheets guides is interposed between two different supports of the plurality; # an air system; # wherein the each of the supports defines an outer surface, at least one of the outer surfaces having a first portion in which a sucking action is exerted by the air system to attract the sheet towards the outer surface and a second portion in which a blowing action is exerted by the air system to push the sheet away from the outer surface.

A web handling system is disclosed. The web handling system includes first dancer rollers coupled to engage and move a web of a print medium in a forward and backward direction upon stopping a printing operation and allow forward motion during the printing operation.

The present invention relates to a web film movement compensating device for a web film movement compensation between continuous forward movement section and intermittent forward movement section comprising two guide rollers (1, 2) rotating freely in stationary positions between a continuous driving device (5) and an intermittent driving device (6), two compensation rollers (3, 4) rotating freely on two respective pivoting arms (7, 8) oscillating about pivot shafts (11, 12), an elastic element (9) connected to one of the pivoting arms to actuate the corresponding compensation roller to move away from the guide rollers, and a movement transmission mechanism including lever arms and transmission rods (13, 14, 15) transmitting an oscillating movement from one of the pivoting arms (7, 8) to the other. A web film (50) moved by the driving devices is supported on the guide rollers (1, 2) and on the compensation rollers (3, 4) forming a meander.

A web handling system is disclosed. The web handling system includes first dancer rollers coupled to engage and move a web of a print medium in a forward and backward direction upon stopping a printing operation and allow forward motion during the printing operation.

The splicing device for splicing a trailing edge of a first web material to a leading edge of a second web material includes members defining a feed path of the web material. The device also includes a first cutting member and a second cutting member, cooperating with the first cutting member. One of the two cutting members is provided with a movement transverse to the feed path of the web material, to move the cutting member from an operating position, in which it is in front of the other cutting member, to an idle position, withdrawn with respect to the feed path of the web material.

Disclosed is a festooner and a method for buffering a strip, the festooner having a first set of buffer rollers and a second set of buffer rollers, wherein the first set of buffer rollers and the second set of buffer rollers define a meandering first buffer path between them, wherein the festooner further includes a first endless drive element for driving the first set of buffer rollers and the second set of buffer rollers. The festooner further includes a third set of buffer rollers and a fourth set of buffer rollers coaxial to the first set of buffer rollers and the second set of buffer rollers, respectively, defining a meandering second buffer path between them. The festooner further includes a second endless drive element for driving the third set of buffer rollers and the fourth set of buffer rollers.

Disclosed is a festooner and a method for buffering a strip, wherein the festooner includes a first holder and a second holder which are oppositely movable towards and away from each other in a buffer direction to vary a buffer capacity of the festooner, and a first set of buffer rollers and a second set of buffer rollers held by the first holder and the second holder, respectively, wherein the first set of buffer rollers and the second set of buffer rollers define a meandering buffer path between them. The festooner further includes an endless drive element for driving each buffer roller, wherein the festooner further includes an overlength collector for collecting and paying out an overlength of the endless drive element.

The present invention relates to a method of stacking individual sheets and a stacking machine for handling individual sheets, the stacking machine comprising a frame assembly including support columns (711) for supporting the delivery station (70), the transfer station (80) and the elevation station (82). The delivery station has a delivery table (71) and the transfer station including a handling arm (85) is movable from a first position above the delivery table to a second position above the elevation station. The handling arm includes a holding member (86) for contacting the sheets individually and transferring the sheets individually from the delivery table to the elevation station and releasing the sheets individually at the elevation station. The elevation station has a platform for collecting the individual sheets and the platform is moved vertically from a first level to a second level for allowing the sheets to be stacked on top of the one another.

Time required for initial operation and operation immediately after wound body replacement is shortened. A packaging device packages an object to be packaged using a wound body. An elongated sheet-shaped packaging material is wound into the wound body. The wound body includes a recording medium that stores information. The information recorded in the recording medium includes remaining amount information indicating a remaining amount of the packaging material in the wound body. The packaging device includes a drive unit that generates driving force in order to rotate the wound body, an information reader that reads the remaining amount information stored in the recording medium, and a controller that controls the packaging device. The controller sets a rotation speed of the wound body based on the remaining amount information read by the information reader.

A device for splicing and continuously providing an outgoing film web includes a splicing unit for splicing a first or a second incoming film web to the outgoing film web, and a clamping unit and an intermediate film storage for the outgoing film web. The splicing unit includes a first sealing jaw with a first holding device for the outgoing film web, and a first cutting device for severing the outgoing film web in the region of the first sealing jaw. The splicing unit includes a second sealing jaw with a second holding device alternately for the first or the second incoming film web, and a second cutting device for severing this incoming film web. The sealing jaws with their respective holding devices can be displaced relative to one another out of the region of action of their first and second cutting devices into their mutual region of action.
