Problems solved by technology

[0005] According to the device described in WO00 / 12974, comprising: a temperature measurement sensor to compensate for a temperature fluctuation generated by the processor, however, said design has the disadvantage that the temperature compensation affects the overall measurement result , so this is not an optimal solution, since it is expensive on the one hand, and it is based on the necessary empirical calculation method

Embodiment Construction

[0037] A kind of adjustment principle of drafting device 1 will pass through next figure 1 The examples shown are explained. Inserted fiber sliver 2, here is 6 fiber slivers 2 The thickness of the fiber sliver is detected by a microwave sensor 3 at the entrance of drafting device 1, and this microwave sensor works according to the principle of cavity resonance device (microwave generator is shown in Fig. not marked). The funnel 18 is a compression device used to compress the fiber sliver 2, which is connected to the front end of the cavity resonator. After passing the microwave sensor 3, the fiber slivers 2 are output in the form of wool entering the drafting device 1 (triangularly extended towards the drafting device 1). In this embodiment, the drafting device 1 is composed of a pair of entrance rollers, a pair of intermediate rollers and a pair of supply rollers (only the descending roller pairs 20, 21 and 22 are shown in the figure). The drafting of the fiber sliver 2 is...

Abstract

The invention relates to a spinner preparation machine with a drawing gear (1a), for drawing at least one fibre web (2), in particular, a carding, drawing (1), or combing machine with at least one microwave sensor (3; 30; 300; 3000) at the inlet or the outlet from the drawing gear (1a), for measuring the web thickness of the at least one fibre web (2). The microwave sensor (3; 30; 300; 3000) comprises at least one cavity resonator, through which the at least one fibre web (2) is to be run during the measurement. According to the invention, the spinner preparation machine has means (14; 15; 45) for the prevention of temperature-dependent deformations of the resonator walls (302, 306) of the microwave sensor (3; 30; 300; 3000) during the measurements. A cavity resonator for such a microwave sensor is also disclosed.

Description

technical field [0001] The invention relates to a spinning preparation machine with a drafting device for drawing at least one fiber sliver, in particular a carding machine, drafting machine or combing machine with at least one microwave sensor, provided At the inlet and / or outlet of the drafting device for measuring the thickness of at least one fiber sliver, the microwave sensor comprises at least one cavity resonator through which at least one fiber sliver is drawn during the measurement . The invention also includes such a cavity resonator device. Background technique [0002] In the spinning industry, a fibrous structure such as wool is first produced, which after a series of process steps becomes a bent yarn as the final product. Such spinning machines, such as carding machines, drafting machines or combing machines, are arranged counter to the production direction of the yarn and have the effect of balancing the mass fluctuations of one or more fiber slivers. For t...
