ABSTRACT:
An apparatus for measuring a travelling fiber lap prior to introduction thereof into a fiber processing textile machine. There is provided a thickness measuring device contacting the fiber lap for mechanically detecting thickness fluctuations thereof. A first transducer is connected to the thickness measuring device for converting mechanical signals into electric signals representing the thickness fluctuations, and a computer is connected to the first transducer for receiving the electric signals from the first transducer and a display device connected to an output of the computer. There are further provided a weighing device for continuously determining the weight of the travelling fiber lap; a second transducer connected to the weighing device and to the computer for applying thereto signals representing the momentary weight of the fiber lap passing through the weighing device; a first fiber lap advancing arrangement situated upstream of the weighing device for advancing the fiber lap to the weighing device; and a second fiber lap advancing arrangement situated downstream of the weighing device for withdrawing the fiber lap from the weighing device.
