Provided is a transport device including a feeding unit on which a roll-type medium is set and which feeds the medium by rotating the medium, and an endless transport belt that transports the medium in a transport direction by supporting the medium fed out from the feeding unit and rotating. When seen from a support direction in which the transport belt supports the medium, the feeding unit is configured to change the posture thereof so as to incline a rotating shaft of the medium with respect to a width direction that is a direction intersecting the transport direction.

The subject matter of the present invention is a method and a device for producing an adhesive tape (1). First a material web (2) comprising a carrier tape material is supplied from an unwinding unit (3). The supplied material web (2) is subsequently provided on at least one surface with at least one adhesive strip (4) in a coating unit (6). The material web (2) provided with the adhesive strip (4) is then cut into at least two longitudinal strips with the aid of a cutting device (10) and made up into individual adhesive tapes (1). According to the invention, a sensor (8, 9) scanning the material web is used to align the material web (2) and/or the cutting device (10) in the transverse direction (Q) in such a way that a longitudinal cut (S) respectively produced with the aid of the cutting device (10) is introduced in an exact position into the material web (2).

An assembly comprises a device for producing a corrugated board web laminated on one side comprising a fluting device for fluting a first material web and a pressing device for pressing the glued corrugated web and a second material web against one another. The assembly comprises a first transverse position detecting device, upstream the fluting device, for detecting the first material web, a second transverse position detecting device, upstream the pressing device, for detecting the second material web and a signal processing unit, which is capable of actuating a unrolling device for unrolling the second material web so that in the device for producing a corrugated board web it is transversally displaced correspondingly.

An apparatus (20) for steering a web (22), including a web path having at least one steering roller (24) and an exit roller (26), each having a mount; wherein the steering roller(s) (26) each have an axis of rotation and wherein the mounts for the steering roller(s) (26) can pivot those axes with a total of two degrees of freedom. An array (30) comprising a plurality of sensors (30a) for monitoring the position of the web (22) is present connected to a controller so as to determine the position and angular orientation of the web (22). The controller adjusts the pivot(s) of the mount(s) so as to control the angular orientation and the lateral position of the web (22) at a particular point along the web path.

The present application relates to rolled good feeding device and method. Material feeding devices and methods are provided for conveying material from material rolls. The material roll may be adjusted in the longitudinal direction during the feeding process by a rectifying frame to aid in maintaining alignment during the unrolling. Tension of the unrolled material may be monitored and unrolling speeds of the feeding device can be adjusted to maintain tension of the material within a range for that material. Aspects also contemplate elements to feed multiple rolled materials simultaneously for subsequent processing in combination as layered materials.

Unwinder of a thin ply product wound on a roll, of the type with automatic switching of the unwinding roll with a spare roll, said unwinder comprising—a first roll-holder assembly equipped with a first unwinding rod for a respective roll, on which the roll is adapted to be supported, and which has an axis of rotation transversal to the direction of movement of the ply unwound from the roll, —a second roll-holder assembly equipped with a second unwinding rod for a respective roll, on which the roll is adapted to be supported, said second rod being parallel to said first unwinding rod of the first roll-holder assembly, said second roll-holder assembly facing said first roll-holder assembly in an unwinding zone, wherein of said two roll-holder assemblies, one assembly holds the unwinding roll and the other assembly holds the spare roll to be switched, —a ply splicing assembly placed above said first and second facing roll-holder assemblies, —a ply accumulation unit to allow automatic switching between a roll being unwound in one said roll-holder assembly and a spare roll provided in the other roll-holder assembly, —a transversal position correction system for the side edges of the plies on the rolls present in said roll-holder assemblies.

Maintaining a level of tension on material as it is processed in a manufacturing operation assists in the processing of the material. The tension of the material as it is fed through a process station is maintained by a material sag portion, such as an unsupported portion of the material extending between a roll of the material and the process station. The formation of the sag portion and the loading of the material forming the sag portion are automated and adjusted with a system having a material storage retrieval system, a shuttle, a tensioning device, and/or a processing station.

A roll paper steering device includes a guide rail fixed to a main body frame, a guide engaged with the guide rail, a holding shaft fixing member supported by the guide rail via the guide, a roll paper holding unit including a roll shaft and mounted to the holding shaft fixing member, a movable member configured to adjustably mount to the holding shaft fixing member, a nut member that includes an internal thread portion that screws into the external thread portion and that is fixed to the main body frame in a posture where the axis of the external thread portion is parallel with the guide rail, a first adjustment unit configured to adjust the posture of the holding shaft fixing member, and a second adjustment unit configured to adjust the position at which the movable member.

Unwinder of a thin ply product wound on a roll, comprising a first roll-holder assembly equipped with a first unwinding rod for a respective roll, on which the roll is adapted to be supported, and which has an axis of rotation transversal to the direction of movement of the ply unwound from the roll, a second roll-holder assembly equipped with a second unwinding rod of a respective roll, on which the roll is adapted to be supported, said second rod being parallel to said first unwinding rod of the first roll-holder assembly, said second roll-holder assembly facing said first roll-holder assembly in an unwinding zone, a ply splicing assembly placed above said first and second facing roll-holder assemblies, a ply accumulation unit to allow automatic switching between a roll being unwound in one said roll-holder assembly and a spare roll provided in the other roll-holder assembly, a system for the lateral movement of each of said unwinding rods with respect to said unwinding zone, from said unwinding zone to a loading zone wherein said rolls are outside said winding zone to facilitate loading the rolls into the respective roll-holder assemblies, wherein said splicing assembly can be moved from a working position above the two said roll-holder assemblies in said unwinding zone, to a working position above an extracted roll assembly in the loading zone, to allow preparation for splicing of the leading edge of the ply wound on the spare roll.
