Embodiment Construction

[0019] Such as figure 1 As shown, a draw frame 1 , for example of the Trützschler TD03 type, has a drafting unit 2 , upstream of which is an inlet 3 of the drafting unit 2 and downstream of which is an outlet 4 . The sliver 5 from the can (not shown) is drawn into the sliver guide 6 by take-off rollers 7, 8 and conveyed past the measuring element (distance sensor 9). The drafting mechanism 2 is designed as a 4-up and 3-down drafting mechanism. That is, it includes three bottom rollers I, II, III (output bottom roller I, middle bottom roller II, input bottom roller III) and four top rollers 11, 12, 13, 14. Combination of fiber strands 5 formed from a plurality of fiber strands 5 IV The drafting is carried out in the drafting mechanism 2. The drafting process includes pre-drafting and main drafting. The roller pairs 14 / III and 13 / II constitute the pre-drafting zone and the roller pairs 13 / II and 11, 12 / I constitute the main drafting zone. Fiber strip merged body 5 I Drawin...

Abstract

An apparatus for or on a spinning room preparation machine for correcting a measurement signal relating to the thickness of at least one textile fibre sliver, which signal is obtained from a pair of sensing rolls 7, 8, one of the sensing rolls 7 is arranged in fixed position and the other sensing roll 8 is force-loaded and arranged to be movable away from the fixed sensing roll. A periodic error value caused by non-circularity and / or eccentricity of the pair of sensing rolls 7, 8 is detectable, the pair of sensing rolls being connected to a displacement sensor 64 and a rotational angle transmitter which send their signals to a signal processing means and the output of the processing means delivers the corrected measurement signal. In order that the concentricity error can be detected and corrected simply and quickly, it is possible to establish touching contact between the circumferential surface of the fixed sensing roll 7 and the sensing roll 8 that is movable and the sensing rolls 7, 8 are rotatable while in touching contact.

Description

Technical field: [0001] The invention relates to a device for correcting a measurement signal relating to the thickness of at least one textile fiber sliver, which is used on a spinning room preparation machine, in particular a card, draw frame, comber or roving frame From a pair of sensing rollers, wherein one of the two sensing rollers is arranged in a fixed position and the other sensing roller is loaded with pressure and arranged so as to be movable away from the fixed sensing roller, and it is possible to detect the Periodic error values ​​due to out-of-roundness and / or eccentricity of the pair, the induction roller pair is connected with the electronic signal forming device (displacement sensor) and the angle transmitter that sends the signal to the input of the electronic system and sends the corrected measurement signal The output terminal of the electronic system is connected. Background technique: [0002] It is common practice in production to measure the thickne...
