Abstract
A monitoring process is provided for a method for producing a nonwoven product. Properties of a nonwoven pre-product (3), in particular the humidity, the electric charge, the weight distribution, the fiber orientation, the fiber mixing ratio and/or the fiber opening degree of an unprocessed fiber web, are detected by a detection unit (41) having one or more sensors (410).
Claims28
A monitoring process for a process for producing a nonwoven pre-product, the monitoring process comprising:
- detecting properties of a nonwoven pre-product, including one or more of weight per unit area, fiber orientation, fiber-blending ratio fiber opening degree, moisture content, temperature and electrical charge, with a detection unit in a detection zone;
- processing detection results in a data processing unit, wherein the nonwoven pre-product in the detection zone is still an unprocessed fiber web and the properties of the nonwoven pre-product are detected over the width of the nonwoven pre-product across a production direction;
- and
- generating actuation commands fora nonwoven pre-production plant comprising a fiber processing device or a web forming device or both a fiber processing device and a web forming device.

A monitoring unit for a nonwoven fabrication plant, the monitoring unit comprising:
- a detection unit configured to detect properties of a nonwoven pre-product in a detection zone, wherein the detection unit comprises one or more of an infrared sensor, a radioactive radiation sensor and an X-ray sensor, wherein the detection unit is configured to detect properties of an unprocessed nonwoven pre-product over a width of the nonwoven pre-product across a production direction;
- and
- a data processing unit configured to generate actuation commands for a nonwoven pre-production plant comprising a fiber processing device or a web forming device or both a fiber processign device or a web forming device.

A nonwoven pre-production plant comprising
- a fiber processing device;
- a web forming device cooperating with the fiber processing device for forming a nonwoven pre-product;
- and
- a monitoring unit comprising:
- a detection unit configured to detect properties of the nonwoven pre-product in a detection zone, wherein the detection unit comprises one or more of an infrared sensor, a radioactive radiation sensor and an X-ray sensor, wherein the detection unit is configured to detect properties of an unprocessed nonwoven pre-product over a width of the nonwoven pre-product across a production direction;
- and
- a data processing unit configured to generate actuation commands for a nonwoven pre-production plant comprising a fiber processing device or a web forming device or both a fiber processing device or a web forming device.
