Abstract (en)
[origin: EP0500467A1] The subject of the present invention is a procedure and a machine for continuously controlling an endless web. <??>This machine essentially comprises a frame 1 supporting two cylinders 2,3 which are capable of rotationally driving an endless web B to be controlled, and carrying, above the web B, two systems 10,11 for injecting a dye (colouring agent) and two cameras 12,13 connected to a computer O, while an encoder 8 is mechanically connected to the shaft of a motor 7 for rotatably driving one 2 of the two cylinders and is electrically connected to the injection systems 10,11 and to the cameras 12,13. <??>The procedure and the machine of the invention enable the misalignment (frame misregistration) of the coloured patterns on a fabric to be assessed with high accuracy and the mean position of the neutral fibre in an endless web to be measured very accurately. <IMAGE>
