摘要： A device determines the true feed transmitted by a feed device of an industrial sewing machine to the sewn material. The number of threads passing in front of a sensor is counted and the feed is derived from the predetermined thread density. In order to obtain a thread count of maximum precision irrespective of the orientation of the sewn material, a rotating slit diaphragm (7) with at least one parallel-edged radial slit (8) is arranged in front of the photoelectric cell (10) of the sensor. Preferably, a second, stationary slit diaphragm (5) whose angular position can nevertheless be varied comprises a slit (6) which opens over a certain angular range. The rotary slit diaphragm (7) has a larger number of slits (8). The required rotational speed of the rotary slit diaphragm (7) can therefore be reduced. To prevent errors due to the pattern of the fabric, the device can function in the relatively long infrared wavelength range.

摘要： Process and device for measuring the speed and/or length of endless lengths of cloth. A beam of light (10, 10b) is directed onto the length of cloth (15), a first part (10a) of said beam being deflected before it can strike the surface of the length of cloth (5), and the deflected beam of light is passed to an evaluation device (6, 7). The light beams (10c, 10d) reflected from the surface of the length of cloth are directed over a convergent lens (4) and they too are passed to said evaluation device (6, 7), causing the corresponding beams of light (10a, 10c, 10d) to be superimposed. The frequency (fd) of the interference created by the superimposition of the light beams determines the speed (v) and/or length of the length of cloth (5).
