Choose the Right Side 95% of all the industrially produced flat glass today is made using the float glass process. In this process, molten glass is continuously fed into a bath of molten tin. Due to its lower specific weight the molten glass floats on the smooth tin surface, and on a long tin bath forms a uniformly thick and extremely smooth film. The glass side that faces the molten tin is slightly contaminated with tin, which has corresponding effects on subsequent float glass processing steps such as coating of the glass surface. For the further processing of float glass it is therefore important that the surface that is contaminated by the tin bath can be distinguished from the so-called fire side (fire polishing, during float glass production the glass side facing away from the molten tin is heated).. |

Problems With Folds? In the production of oil and air filters for the automobile industry these filters must reach the required throughput rate, which is achieved by folding the filter material so that it provides a large filter surface on a minimum of space. Depending on the filter type there are differences in the fold depth and in the numbers of folds. |

Welding Seam Detection With Edge Detectors For the detection of welding seams, contrast or color sensors would seem to be the proper solution, because in most cases the welding seam optically shows a clear difference from the surrounding product surface. In everyday practice, however, it turns out that these methods involve frequent readjustment and reparameterisation. |

Connected to the Future! Up to now it may have been sufficient for a sensor manufacturer to provide systems with digital outputs, a 0V to +10V analog voltage output, and a 4mA to 20mA analog current output. In the foreseeable future, however, communication between sensors and programmable logic controllers (PLCs) primarily will be performed in digital serial form with a correspondingly high data rate. The future belongs to the so-called Industrial Ethernet. |

Detection of Transparent Edges Conventional detectors particularly reach their limits when they have to detect and count stacked transparent objects such as plastic drinking cups of plastic caps. Especially in the process of packaging, however, it is of great importance to place the exact number of objects in a packaging unit. Such problems now can be solved with the RED series (a RED-110-L was used for this application). |

A Hazy Problem? At first everything seemed to be quite clear, just another measurement task that we surely would manage without any problems with one of our GLOSS series sensors. According to the descriptions provided by the customer it seemed to be gloss grade measuring task, and at the beginning the only question seemed to be at which angle measurement should be performed: 20°, 60° or 85° from the vertical? |

Perfect Copy Counting
When cartons, magazines, or single sheets are packed, it must be ensured that each package has the correct number of items. In most cases such material is transported in shingled form before, as with magazines, newspapers or advertising prints, it is packed by means of a compensating stacker. Depending on the thickness of the individual copies and on their transport speed (up to 10m/s) the shingled stream may have differing heights in this process. ► Press release |

Clear Strategy or Plain Guessing? In the last years the spray nozzles at windscreens have seen quite some development. The jet now comes as a fan jet or spot jet. A homogeneous spray mist application onto the intended angle range is now accurately guaranteed with fan jets, as is the point-shaped jet application on the front cameras by means of exactly directed and hardly diverging spot jets. ► Press release |

INLINE Color Measurement of Paint Through a 15mm Thick Inspection Glass Usually the color checking of color paint during production primarily is done in a laboratory. A paint sample is taken, and the color of this sample is then checked by way of a thin paint layer in dry condition. This process of course takes some time, time in which paint production might run out of the permissible tolerances and thus might require time-consuming and expensive follow-up treatment. ► Press release |

Accurate High-Speed Counting of Stacked Plastic Caps Especially the counting of transparent, stacked plastic caps, as they for example frequently are used in the packing industry, usually is a highly problematic application because on the one hand the edges of individual caps are not always exactly aligned, and on the other hand copy counters that work with the reflected-light principle do not provide a reliable counting result especially with transparent objects.
