Disclosed is a Transport apparatus (1) for supply rolls (8) with packaging material wound thereon. The transport apparatus (1) comprises at least one driverless transport vehicle (2) and at least one adapter (3).

The adapter (3) is preferably connectable to the driverless transport vehicle (2), as well as being separable from the driverless transport vehicle (2).

The adapter (3) is moreover designed to hold at least one supply roll (8).

The invention describes a roll-removal device by means of which a plurality of rolls which have been wound to completion are transported away from a winding shaft having a displacement device for displacing the rolls relative to the winding shaft, in order to withdraw the rolls from the winding shaft, having a receiving device for receiving the rolls, and having a transfer device for transferring the rolls from the displacement device to the receiving device, wherein the rolls can be rolled freely at least in certain regions, the rolls rolling about their rolling axes. By means of this device for changing the position of the rolls axes, the roll axes of two adjacent rolls can be moved to an angle of less than 180 degrees in relation to one another.

The invention relates to a coil-transporting carriage with adjustable retaining arms and to a method for the reliable handling of metal coils of small external diameter, or of sleeves, on a coiler mandrel. The coil-transporting carriage has a vertically displaceable coil saddle for accommodating a coil or a sleeve, also has two retaining arms for stabilizing the coil or the sleeve, the retaining arms being arranged opposite one another on the coil saddle and being pivotable by means of rotary drives, and additionally has a second drive unit for moving the coil-transporting carriage. For pulling off from a coiler mandrel, the coil saddle is positioned against a coil located on the coiler mandrel and the retaining arms are pivoted onto the coil. For pushing onto a coiler mandrel, first a sleeve is placed on the coil saddle of the coil-transporting carriage and is thereby guided by the retaining arms.

A printing apparatus and a conveying apparatus are provided. The printing apparatus is provided with a main body unit including a printing unit configured to print on a medium and legs supporting the printing unit. The printing apparatus includes a pair of holding members configured to hold both ends, in an axial direction, of a roll of media at a position vertically above a floor surface on which the main body unit is placed. The roll of media is formed by winding the medium. A drive unit is configured to rotate the roll of media held by the holding members. A guide member connected to the main body unit is configured to support the holding members moveably in a width direction X. The guide member is disposed at a position horizontally closer to the main body unit than the holding members.

Method and machine for discharging at least one roll of tape from a winding spindle, according to which a cradle for partially housing the roll is fed by means of a motorized cart with wheels rolling on the floor below the roll and is then lifted to bring the roll into engagement with the cradle; during lifting of the cradle, the position of the same cradle with respect to the cart is adjusted in a horizontal plane by the action exerted by the same roll mounted on the winding spindle.

A method for transferring unwinders (36) using a transfer facility (38) comprising a control unit (39) for controlling the unwinders, and at least one autonomous mobile platform (40) is disclosed. The facility comprises measurement means for measuring the quantity of product wound on reels (22) supported by the unwinders and communication means. The method comprises the following successive operations: measuring the quantity of product wound on the reels and communicating the measured data to the control unit; on the basis of the measured data, determining the moment at which to transmit a removal or supply mission instruction to a mobile platform; transmitting to a mobile platform at the previously-determined moment, a mission instruction to remove or to supply a unwinder; and moving the mobile platform in such a way that it becomes positioned under a unwinder.

The invention relates to a system for feeding a coating material from a modular unit to a coating device, said modular unit (40-42) being provided for the storage and provision of preferably roll-type or coil-type coating material units, in particular edge strips (K) for applying to a narrow side of panel-type workpieces (W) and said feed system having: a feed section (20) for holding and transporting the coating material; a cassette unit (25) for guiding the coating material provided by the feed section (20); at least one mobile modular unit (40-42); and a coupling section (30) for coupling the mobile modular unit (40-42) to the feed section (20), the modular unit (40-42) holding coating material units.

The disclosed supply roll (5) comprises a roll core (6); flat material and/or strip material (8) being carried on the roll core (6) in a multitude of windings; and at least one functional marker (2). The at least one functional marker (2) is placed in a specified relative position at an externally arranged free end section (7) of the flat material and/or strip material (8) such that information about the relative position of the free end section (7) is optically identifiable by way of the at least one functional marker (2).

A process for improving the convertability of parent rolls of convolutely wound web materials is disclosed.
