Problems solved by technology

If only a few strain gauges are used, the measurement accuracy will be too poor
Installing strain gauges as above would be very expensive
The connection cost between the strain gauges is also relatively high and the workload is heavy. Since these strain gauges are installed on the rotating cover and rotate synchronously with the rotating cover, these strain gauges must be connected to the fixed components that receive the signal for signal transmission.

Embodiment Construction

[0021] Embodiments of the present invention will be described with reference to the accompanying drawings.

[0022] As shown in FIG. 1 , shown in plan: the carding machine perpendicular to the axis of rotation of the carding roller or drum 2 . The cladding surface 8 of the drum 2 is fitted with a set 9 for handling the fibrous material. The adjuster 9 consists of a tensioned toothed wire, wherein the tips of the individual teeth point in the direction of rotation or carding B. The design of such a regulator 9 is well known in the prior art and will not be described further here. It can be seen that the direction indicated by the arrow B is the direction in which the drum 2 rotates clockwise. On the left, the figure has a schematic representation of an open-width roll 10 , which feeds the drum 2 with fibers. The supply unit 4 is connected to the open roll 10, said unit supplying the open roll 10 with fibers. It is also possible to use known open width roll equipment. The p...

Abstract

The invention refers to a card engine or card machine comprising a measuring device for detecting the forces prevailing between the revolving cover and the drum. The device shall be improved in such a manner that the quality of the treated fibres can be influenced in an economical and efficient manner. This is achieved by virtue of the fact that the measuring device comprises a sensor for detecting the power consumption of the drive of the revolving cover. The sensor is arranged on the drive of the revolving cover or acts thereas, thereby facilitating the use of commercially available elements, which in turn is more economical.

Description

technical field [0001] The invention relates to a carding machine comprising a measuring device for detecting the strength present between a rotating cover and a drum. technical background [0002] Carding machines already exist that measure the power state between the rotating cover and the drum. According to the prior art, strain gauges are mounted on the rotating cover to detect the forces generated during the operation of the carding machine. [0003] However, the prior art also reveals some disadvantages. On the one hand, the individual components that play an auxiliary role, the strain gauges, must be mounted on the carding machine. This results in a high cost. On the other hand, it is useless to use only one or a few strain gauges, multiple strain gauges must be used. Only then is the entire width of the swivel cover covered by the strain gauge. If only a few strain gauges are used, the accuracy of the measurement results will be too poor. Installing strain gaug...
