The invention relates to a paper making machine (1) comprising a forming section (2) in which a fibrous web (W) can be formed, a drying section (5) in which a formed fibrous web (W) can be dried; and a reel-up (11) on which a dried fibrous web (W) can be wound into a roll (12). The paper making machine (1) is arranged to carry a fibrous web (W) in the machine direction (MD) along a predetermined path (P) and the paper making machine (1) has at least one water jet cutting device (17, 18, 19) arranged to cut the fibrous web (W) that is moving in the machine direction (MD) such that the fibrous web (W) is divided into at least one waste part (23a, 23b, 30) and a remaining part (24, 29). The paper making machine (1) is arranged to direct the at least one waste part (23a, 23b, 30) away from the predetermined path (P) and to convey the remaining part (24, 29) further in the machine direction (MD) along the predetermined path (P). The paper making machine (1) further comprises a blowing device (20, 21, 22) arranged to blow gas or air against the water jet cutting device (17, 18, 19) in a direction toward the remaining part of the fibrous web (24, 29) such that fiber particles that have been released by the cutting action of the water jet cutting device (17, 18, 19) are blown onto the surface (25) of the remaining part (24, 29) of the fibrous web (W) and follow the remaining part (24, 29) of the fibrous web along the predetermined path (P). The invention also relates to a method in which gas or air is blown in a direction toward the remaining part of the web such that fiber particles that have been released by the cutting action of the water jet cutting device (17, 18, 19) are blown onto the surface (25) of the remaining part (24, 29) of the fibrous web (W). The stream of air or gas is given a shape which is circular cylindrical or conical and expanding in the direction in which the stream moves.

A processing system (10) and corresponding method (158) are provided for processing workpieces (WP), including food items, to cut and remove undesirable components from the food items and/or portion the food items while being conveyed on a conveyor system (12). An X-ray scanning station (14) is located on an upstream conveyor section (20) to ascertain size and/or shape parameters of the food items as well as the location of any undesirable components of the food items, such as bones, fat or cartilage. Thereafter the food items are transferred to a downstream conveyor (20) at which is located an optical scanner (102) to ascertain the size and/or shape parameters of the food items. The results of the X-ray and optical scanning are transmitted to a processor (18) to confirm that the food item scanned by the optical scanner is the same as that previously scanned by the X-ray scanner. Once this identity is confirmed, if required, the data from the X-ray scanner is translated or transformed onto the data from the optical scanner. Such translation may include one or more of the shifting of the food items in the X and/or Y direction, rotation of the food item, scaling of the size of the food item, and sheer distortion of the food item. Next, the location of the undesirable material within the food item is mapped from the X-ray scanning data onto the optical scanning data. Thereafter, the undesirable material is removed by a cutter(s) (28). The food item may also (or alternatively) been portioned by the cutter(s) (28).

A method for perforating a film of plastic material in which the film is perforated whilst it is slid through a perforating device by a plurality of pressurised hot gas jets having a temperature above the melting temperature of the main film, in which the hot gas jets are correlated with the sliding speed of the main film, and in which reinforcing bands obtained from an auxiliary film of plastic material are connected to the perforated main film, making the reinforcing bands adhere between parallel rows of base holes. During perforating, the main film of plastic material is pressed against a perforating template, making the main film of plastic material instantaneously penetrate openings of the perforating template by said hot gas jets. A hot gas perforating device and a suitable apparatus for perforating and stretching a film of plastic material are also provided.

A processing system (10) and a corresponding method are provided for processing work products (WP), including food items, to locate and quantify voids, undercuts and similar anomalies in the work products. The work products are conveyed past an X-ray scanner (14) by a conveyance device (12). Data from the X-ray scanning is transmitted to control system (18). Simultaneously with the X-ray scanning of the work product, the work product is optically scanned at the same location on the work product where X-ray scanning is occurring. The data from the optical scanner is also transmitted to the control system. Such data is analyzed to develop or generate the thickness profile of the work product. From the differences in the thickness profiles generated from the X-ray scanning data versus the optical scanning data, the location of voids, undercuts and similar anomalies can be determined by the control system. This information is used by the processing system (10) to process the work product as desired, including adjusting for the locations and sizes of voids, undercuts and similar anomalies present in the work product.

A method, apparatus, and system are provided to monitor and characterize the dynamics of a phase change region (PCR) created during laser welding, specifically keyhole welding, and other material modification processes, using low-coherence interferometry. By directing a measurement beam to multiple locations within and overlapping with the PCR, the system, apparatus, and method are used to determine, in real time, spatial and temporal characteristics of the weld such as keyhole depth, length, width, shape and whether the keyhole is unstable, closes or collapses. This information is important in determining the quality and material properties of a completed finished weld. It can also be used with feedback to modify the material modification process in real time.

In some aspects, methods for measuring a level of usage of one or more replaceable consumable components within a material processing system can include detecting a type of consumable component in use within a processing device of the material processing system; determining, using a computing system, if the type of consumable component in use is a specific type of consumable component; and determining, using the computing system, a usage ratio of the specific type of consumable component used relative to other types of consumable components used within the processing device during a cumulative time period of use of the material processing system.
