from the web 14 or a wide angle setting can be used on the camera in order to record the entire web width at one time the camera 15 can also be pivotable in order to record images across the working width of the draw frame the web guide hinged members 7 e 7 f are transparent so that recordings of the web 14 are produced with the web guide 7 closed the recordings are made of reflected light and transmitted light for that purpose leds are located on the camera side and on the draw frame side respectively it is possible to record images of the web at delivery speed and when accelerating and decelerating advantageously recordings are made in the middle region of the web in order to examine the web for uneven patches the cause for this can include poor short fibre guidance poor gripping of the web wrong drafting system settings furthermore recordings of this web area can be used to analyse the degree of parallelization of the fibres the number and size of neps the structure influence of the material and dust formation that occurs using all these influences the quality of the drafting process can be determined preferably recordings are also made specifically of the edge region in order to be able to analyse the guidance of the edge fibres in the drafting process closed or incomplete web structure at the edges it is thus possible when removing the web to determine whether there will be striations along the fibres across the working width.
