A printing system and a method for printing a plurality of images on a first web and on a second web are disclosed. The printing system includes a print head, a feed unit for feeding both the first web and the second web simultaneously to the print head in a feed direction relative the print head, a wrap up unit for wrapping up both the first web and the second web simultaneously to form a first output roll and a second output roll respectively, a user interface configured to set a printing arrangement of the plurality of images on the first web and the second web and to input the print head, the feed unit and the wrap up unit for performing printing according to the printing arrangement by ejecting marking material on the respective webs. The printing system includes a prediction module for predicting a first diameter of the first output roll and a second diameter of the second output roll based on the printing arrangement. The prediction module is configured to establish a difference of the predicted first diameter and the predicted second diameter, and to provide to the user interface a warning when the established difference is larger than a predetermined diameter difference threshold.

Methods and apparatus for supporting a paper roll in a paper bucket of a printer are provided. The paper bucket may comprise a curved base portion for accepting paper rolls of varying widths, two oppositely disposed side walls movably mounted to the curved base portion, and a two-part spring-loaded spindle assembly extending through each of the side walls and adapted to support a paper roll therebetween. Each spindle assembly may comprise a first spring loaded spindle part and a second spring loaded spindle part movably connected to one another.

A sheet product dispenser for dispensing sheet product from a roll of sheet product is provided. An example sheet product dispenser includes a housing defining an interior space for receiving a first roll of sheet product therein, a mandrel positioned within the interior space, and a spindle positioned over at least a portion of the mandrel and configured to support the first roll of sheet product for rotation about the mandrel. The spindle comprises a base portion and a nose portion configured to translate relative to one another along a longitudinal axis of the mandrel. At least a portion of the spindle is configured to translate relative to the mandrel from a first configuration to a second configuration to cause a remainder of the first roll of sheet product to deform and enable movement of a dispensing door to enable access to a second roll of sheet product.

A system for feeding a coating material from at least one movable modular unit to a coating device is provided, the at least one movable modular unit being provided for the storage and provision of roll-type or coil-type coating material units including edge strips for applying to a narrow side of panel-type workpieces. A feed section holds and transports the coating material. A cassette unit guides the coating material provided by the feed section. A coupling section couples the at least one movable modular unit to the feed section, the at least one movable modular unit holding coating material units.

A method for arranging elongated elements in a process for building tyres for vehicle wheels, including: simultaneously winding a first elongated element and a second elongated element respectively on a first winding support in a first axial position and on a second winding support in a first axial position; simultaneously winding a third elongated element and a fourth elongated element respectively on the first winding support in a second axial position different from the first axial position and on the second winding support in a second axial position different from the first axial position, in which the elongated elements of the second type are the same as each other and different from the elongated elements of the first type.

A method for arranging elongated elements in a process for building tyres for vehicle wheels, including: arranging a first winding support with a first elongated element of a first type wound on the first winding support; arranging a second winding support with a second elongated element of a second type different from the elongated element of the first type wound on the second winding support; arranging a coupling device including a first coupling body and a second coupling body rotatable with respect to one another about a rotation axis; and arranging the first winding support on the first coupling body and the second winding support on the second coupling body.

A label dispenser coupled to product-transporting carts at retail facilities includes a label roll support arm supporting multiple label rolls thereon, a label guide arm including openings that permit a leading portion of the backing substrate of a label roll to pass therethrough, and a side wall interconnecting the label roll support arm and the label guide arm. The label guide arm also includes an upper portion located above the openings and configured to support the backing substrates of the label rolls thereon. The label guide arm further includes an edge configured to facilitate separation of a leading peelable label from the backing substrate in response to a force applied by the user when pulling the leading portion of the backing substrate of the label roll through the opening of the label guide arm.

The present invention relates to a device (20) for winding a longitudinally cut material web having multiple longitudinal strips (12) on a plurality of winding tubes (16) to form in each case a wound roll. The device comprises an axle (24) and, mounted on the axle, a plurality of ring-shaped winding drives (22) that are individually controllable in their operating position. Each winding drive (22) forms an external-rotor electric motor and comprises a static interior tube (40) and a rotatable external tube (50). The external tube (50) that is rotatable on the rolling bearings (48) bears, on its interior, a device for providing an excitation magnetic field (52) that forms the external rotor of the electric motor.
