  • Method and an apparatus for cambering the edges of webs of thermoplastic materials on one and both sides using the energy of ultrasonic vibration
    Patent number: 4247273
    Abstract: The invention relates to an apparatus and a method for cambering the edge of webs of thermoplastic materials on one or both sides wherein the edges of the web are continuously guided through stamping units and the edges are provided with stampings. The thermoplastic cambering is made by utilizing the energy of ultrasonic vibration. The stamping unit consists of a stamping wheel with pressure apparatus for the wheel and a stationary ultrasonic head arranged beneath it with a sonotrode. A calibration apparatus can be arranged downstream of the stamping unit.

  • Method of detecting faults in moving webs of materials
    Patent number: 4118127
    Abstract: A web of paper or foil to be investigated is optically scanned line by line transversely to its direction of movement by a stationary scanning device and read off in reflection. The length of scanning line is greater than or equal to the width of the web of material under investigation. At least one time mark is formed electronically within a scanning line, which mark, starting from one end of the scanning range, is shifted forwards by a constant step with each scanning movement until the other end of the scanning range has been reached. The instantaneous value of reflected signal appearing in each case at the time mark is then averaged out over a cycle consisting of several scanning movements. A fault is only indicated if there is a deviation from the average value.

  • Process and apparatus for detecting longitudinal faults on moving webs of material
    Patent number: 3972624
    Abstract: In a process for detecting longitudinally orientated faults on moving webs of paper or film, the web is optically scanned line by line transversely to its direction of movement and read by reflection. The scanning line is moved to and fro across the whole web at constant velocity and during a given number of scanning movements the instantaneous value of the reflected signal is interrogated at two fixed time marks within the scanning line and stored and the average values over a scanning cycle are formed separately for each of the two time marks. The average values ae indicated and recorded as faults only if a value different from the average noise value is obtained from both time marks in succession.
