Abstract

A laminating machine comprises at least one material source, configured as a sheet feeder, for sheets of a material to be laminated. The laminating machine further comprises at least one laminating unit. The laminating machine also comprises at least two lamination sources, each for at least one web-type laminating material. The laminating machine additionally comprises at least one laminating unit for producing a material web, which is laminated on both sides, from the sheets and the respective at least one laminating material. At least one lamination control device is disposed downstream of a laminating region of the laminating unit, along a transportation path provided for the transporting of the laminated material web. The control device monitors a control region, lying outside a transport region that is occupied by the transportation path provided for the laminated material web.

First claim

The invention claimed is:

1. A laminating machine, wherein the laminating machine has at least one material source for sheets of a material to be laminated and being configured as a sheet feeder, wherein the laminating machine has at least one laminating unit, wherein the laminating machine has at least one shingling unit which is usable for placing non-laminated sheets in a shingled arrangement relative to one another, wherein the laminating machine has at least two lamination sources, each of the at least two lamination sources being adapted to supply at least one web-type laminating material, wherein the at least one laminating unit is usable for producing a material web that is laminated, on both sides, from the sheets and from the at least one web-type laminating material supplied by the at least two lamination sources, wherein, downstream of a lamination zone of the laminating unit and along a transport path provided for transporting the laminated material web, at least one lamination monitoring device is arranged, and wherein the at least one lamination monitoring device monitors a monitoring zone, the monitoring zone lying outside a transport zone, the transport zone including at least one transport zone curved section adjacent the at least one lamination monitoring device, the transport zone being occupied by the transport path provided for the laminated material web.

2. The laminating machine according to claim 1 , wherein the at least one lamination monitoring device has at least one first monitoring element configured as a detector, and wherein the at least one lamination monitoring device has at least one second monitoring element configured as a transmitting device, wherein, in the at least one lamination monitoring device, the at least one first monitoring element is configured as a detector for electromagnetic radiation and, wherein, in the at least one lamination monitoring device, the at least one second monitoring element is configured as a transmitting device for electromagnetic radiation.

3. The laminating machine according to claim 2 , wherein a rectilinear subsection of a beam path between the first monitoring element, configured as a transmitting device, and the second monitoring element, configured as a detector, passes a lateral surface of a web deflecting roller in the transport zone curved section at a minimum monitoring distance, and wherein the minimum monitoring distance is one of less than 20 mm and is greater than zero and is shorter than an overlap length of adjacent ones of the sheets within the laminated material web.

4. The laminating machine according to claim 3 , wherein the overlap length of adjacent ones of the sheets is a length, measured along the transport path of the material web, over which adjacent ones of the sheets are in mutual contact within the laminated material web.

5. The laminating machine according to claim 2 , wherein the at least one second monitoring element, configured as a transmitting device, forms a single structural unit with the at least one first monitoring element configured as a detector.

6. The laminating machine according to claim 1 , wherein at least part of the monitoring zone is located at a minimum monitoring distance from a web deflecting roller in the at least one transport zone curved section, and wherein the minimum monitoring distance is one of less than 20 mm and is greater than zero and is shorter than an overlap length of adjacent ones of the sheets within the laminated material web.

7. The laminating machine according to claim 1 , wherein the laminating machine has at least two of the lamination monitoring devices, wherein, of the at least two of the lamination monitoring devices, a first one of the at least two lamination monitoring devices is arranged on a first side of the transport path provided for the laminated material web, and wherein a second one of the at least two lamination monitoring devices is arranged on a second side of the transport path provided for the laminated material web, opposite the first side of the transport path provided for the laminated material web.

8. The laminating machine according to claim 1 , wherein the laminating machine has at least one separating device which is usable for separating sections from the laminated material web, and wherein the at least one lamination monitoring device is located downstream of the lamination zone of the laminating unit and upstream of the at least one separating device along the transport path provided for transporting the laminated material web.

9. The laminating machine according to claim 8 , wherein the at least one separating device has at least one first stretching element and wherein, by moving at least the at least one first stretching element between at least one first traversing position and at least one first separating position, the at least one separating device can be switched between at least one traversing mode and at least one separating mode, and wherein at least one separation sensor device is provided for use in detecting a gap between the material web and a section of the material web most recently separated from the material web.

10. The laminating machine according to claim 8 , wherein the at least one separating device has at least one forward clamping device having at least one forward clamping point, and wherein the at least one separating device has at least one rear clamping device having at least one rear clamping point, and further wherein the at least one separating device has at least one first stretching element, and wherein, by moving at least the at least one first stretching element between at least one first traversing position and at least one first separation position, the at least one separating device can be switched between at least one traversing mode and at least one separation mode.

11. The laminating machine according to claim 8 , wherein at least one separation sensor device is provided for detecting a gap between the material web and the section most recently separated from the laminated material web.

12. The laminating machine according to claim 1 , wherein one of at least one ultrasonic sensor and at least one capacitive sensor is provided as the at least one lamination monitoring device which monitors the monitoring zone.

13. The laminating machine according to claim 1 , wherein downstream of the at least one laminating unit along the transport path provided for the laminated material web, at least one thickness monitoring device is provided, a monitoring zone of the at least one thickness monitoring device overlapping, at least partially, with the transport path provided for the laminated material web.

14. The laminating machine according to claim 1 , wherein at least one webbing-up means that is movable along at least one webbing-up path, for webbing up the laminating material, is provided, and wherein the at least one webbing-up means one of is and can be arranged, at least intermittently, at least within the laminating unit.
