The present invention relates to a device for treating substrates which device is modular and versatile in use. The device for treating substrates comprises a feeder and one or more first sub-structure modules which each comprise a pressure cylinder with devices for fixing a lift and a sheet-conveying device and one or more second sub-structure modules which respectively have a transport cylinder with openings formed on the cover surface thereof, and having devices for fixing a lift and a sheet conveying device. All of the first or second sub-structure modules have the same intersection point for connecting the sub-structure modules on one of the inlet and the exit side and they all can be equipped with an attachment module.

A transport device transports an individualized sheet-shaped workpiece. The transport device includes: an annular transport belt having a first surface and a second surface opposite to the first surface and having a plurality of suction holes extending between the first surface and the second surface; first and second decompression chambers arranged along a moving direction of the transport belt; and a vacuum degree adjusting mechanism provided in the first decompression chamber and adjusting a vacuum degree in the first decompression chamber. The first and second decompression chambers each abut against the second surface, and each suction the workpiece through at least one of the plurality of suction holes toward the first surface such that the transport belt is capable of transporting the workpiece in the moving direction in a suspended state from the first surface.

An endless conveyer belt is stretched between drive and idle rollers. A carriage is arranged so as to reciprocate along the endless conveyer belt. A suction box is arranged between upper and lower belt portions of the endless conveyer belt and fixed to the carriage. A stopper plate is fixed to the carriage and extends across a conveyer surface and upward from the conveyer surface. A conveyance roller pair is arranged at the upstream end of the conveyer surface. A region of the conveyer surface from a stopper plate to the upstream end u forms a sheet accumulation area. A cover sheet covers a region upstream of the suction box in the sheet accumulation area. The cover sheet is subjected to tension in the longitudinal direction by a winding-type constant force plate spring and continually tensed spaced apart from the endless conveyer belt.

A device for overlapping sheets includes at least one blower box and a supply table. Multiple sheets are guided into a region of the blower box consecutively, in the same transport direction, and are arranged at a distance from one another on the supply table. A blower nozzle is arranged in the blower box, on the side thereof facing the supply table. A blowing direction of the blower nozzle is oriented and parallel to the supply table and against the transport direction of the sheets. The supply table is arranged below the blower box and multiple blower nozzles are arranged in the blower box, one after the other, in the transport direction of the sheets, on the side thereof facing the supply table. A respective blowing direction of the blower nozzles is oriented in parallel to the supply table, and against the transport direction of the sheets.

An apparatus for mounting data carriers onto a carrier web has a supply device, a transfer device and a carrier web positioning device. The supply device has a drive roller, a deflector, and at least one carrying belt running around the drive roller and deflector. A transportation path for the data carriers is hydraulically connected to a suction box such that data carriers are drawn by suction onto the carrying belt. The transfer device has a transfer roller hydraulically connected to a negative pressure source such that data carriers located on the outer casing of the transfer roller are drawn by suction onto the outer casing. The transfer roller has an entry region adjacent to the suction box and an exit region adjacent to the positioning device. At the exit region, a data carrier located on the outer casing of the transfer roller can be transferred onto the carrier web.
