According to some embodiments a conveying device for conveying goods includes at least one conveyor belt with an outer contact face against which the goods to be conveyed are held during conveyance. A main negative pressure holding area is provided adjacent to the conveyor belt, the main negative pressure holding area being configured to hold or release the goods to or from the conveyor belt by negative pressure. The conveyor belt includes at least one suction chamber on the outer contact face forming an additional negative pressure holding area, the suction chamber being in fluid communication with negative pressure holding means through at least one opening transversely going through the conveyor belt.

A turning station for metal sheets or metal sheet stacks, having a first support which forms a first support plane for a first side of the metal sheets, and having a second support which forms a second support plane for a second side of the metal sheets. The supports are rotatable about a horizontal rotation axis and provided with a plurality of detents which project beyond longitudinal edges of the metal sheets. The supports are part of a rotary installation with a frame having two end-side rotary bearings on a common rotation axis and a basket which is mounted in the two rotary bearings for motorized rotation about the rotation axis, the basket having end-side linear guides for the two supports. The supports by way of support planes which extend in parallel and are oriented toward one another are held in the basket such that the rotation axis is situated between the two support planes and the two supports in the end-side linear guides are in each case movable in a motorized manner in a movement direction toward and away from the rotation axis. Methods for unpackaging, storing, and turning metal sheet stacks are also provided.

At least one mobile part included in a plate separator is configured movable between a first position and a second position, which is different from the first position. At least one biasing portion biases the at least one mobile part toward the first position. The at least one mobile part includes a contact portion that comes into contact with the top plate when a plate holder lifts the top plate upward. The at least one mobile part is configured to be moved toward the second position as being pushed by the top plate when the top plate in contact with the at least one contact portion is moved further upward, thereby allowing an upward movement of the top plate.

A device for applying coiling-tension to a slit band sheet includes an upper structure that is disposed on the upper side of a band sheet which has been passed through a slitter line and slitted; and a lower structure that is disposed on the lower side of the band sheet and faces the upper structure vertically. In addition, an upper belt is stretched on an outer peripheral surface of the upper structure. A lower belt is stretched on an outer peripheral surface of the lower structure. The upper structure has a first reversing portion, an upper pressing portion, and a second reversing portion. The first reversing portion and the upper pressing portion are integrated with each other. A tension adjusting mechanism is installed on side surfaces of the first reversing portion and the upper pressing portion and a side surface of the second reversing portion.

A conveyance roller for a heating furnace includes: a roller body constituted by a metal tube made of a heat-resistant alloy; at least one holding protrusion provided on an outer circumferential surface of the roller body for holding an object to be heated in the heating furnace, and protruding from the outer circumferential surface of the roller body in a plurality of positions at a given interval in a longitudinal direction of the roller body; and at least one shielding member provided to be adjacent to the at least one the holding protrusion in the longitudinal direction, and covering the outer circumferential surface of the roller body. The at least one shielding member has a thickness not larger than a height of the holding protrusion from the outer circumferential surface of the roller body.

A printing assembly for digital printing on a continuous metal strip, including: a digital printing unit having a printing area and a conveyor belt arranged for advancing the continuous metal strip in a longitudinal direction through the printing area, an inlet guide unit located upstream of the printing unit and configured to guide the continuous metal strip along a path comprising at least one first movable bend which is freely movable in the longitudinal direction, and an outlet guide unit located downstream of the digital printing unit and configured to guide the continuous metal strip along a path comprising at least one second movable bend which is freely movable in the longitudinal direction.

A magnetic device for magnetically coupling to a ferromagnetic body, comprises a housing having a central bore. A plurality of pole sectors arranged within an envelope of the central bore and forming a workpiece contact interface of the magnetic device, each of the plurality of pole sectors comprising a plurality of spaced-apart pole portions arranged at respective distances, wherein a recess of a plurality of recesses separates each pole portion of the plurality of pole portions, wherein a first sector forms a first pole of the magnetic device and a second sector forms a second pole of the magnetic device. A first permanent magnet. A second permanent being moveable relative to the first permanent magnet. And, an actuator operatively coupled to the at least one second permanent magnet to move the at least one second permanent magnet relative to the at least one first permanent magnet.

A method and a vacuum-coating system for coating a band-type material, in particular made of metal. For this, the band-type material is moved, via a conveying section, in a transport direction and is vacuum-coated within a coating chamber, in which a vacuum is applied. A position of the band-type material is adjusted and/or aligned as relates to a center of the conveying section by means of at least one band position control device, which is arranged within the coating chamber.

A method and a vacuum-coating system (10) for coating a strip-shaped material (11), in particular made of metal, are disclosed. Thereby, the strip-shaped material (11) is moved over a conveying section (12) in a transport direction (T) and vacuum-coated within a coating chamber (14) in which a vacuum is applied. When viewed in the transport direction (T) of the strip-shaped material (11), at least one trimming shear (38) is arranged upstream of the coating chamber (14), with which the strip-shaped material (11) is trimmed at at least one strip edge, preferably at both strip edges, in order to produce a constant width for the strip-shaped material (11) over its longitudinal extension.
