ABSTRACT:
Apparatus for measuring the length of textile material wound onto a lap beam and in particular, onto a dyeing beam, having (a) a pressure roll bearing upon the beam lap and mechanically connected with a displacement detecting transducer that emits measurement impulses, (b) a beam-driven shaft encoder that emits a predetermined number of calculation impulses for each revolution of the beam, and (c) a computer that calculates the partial lengths of the laps (lt) from the measurement impulses and the calculation impulses. The displacement detecting transducer is movably or slidingly interengaged with an elongated linear member in the form of a toothed rack hinged so that a projection of one end always intersects the longitudinal axis of the lap beam. A correction read-out is calculated from the diameter of the axle of the lap beam and the position of the point of interengagement of the elongated linear member with the displacement detecting transducer through the pressure point of the pressure roll bearing upon material wound upon the lap beam and the number of rotations of the lap beam.
