Embodiment Construction

[0014] in accordance with Figure 1 to Figure 3 In an exemplary embodiment of the device for continuously measuring the adhesive force of a fiber bundle, the draft force is formed in a similar manner to a ring spinning machine. A feeding device 1 comprising a pair of feeding rollers 11, 12 carries the roving 3 in direction x from a supply bale not shown to the drafting zone 4, whereby the driving feeding roller 11 is coupled to a motor driven by a stepper motor or other suitable type. A separate drive 13 composed of a motor.

[0015] In a preferred embodiment the drive supply roller 11 has a grooved or knurled surface and the pressure supply roller 12 against which the drive supply roller abuts in a known, not shown manner is provided with a rubber coating. A drawing mechanism 2 comprising a pair of pulling rollers 21, 22 draws the roving 3 from the drafting zone 4, whereby the driving pulling roller 21 is coupled to a separate drive 23 consisting of a stepper motor or other ...

Abstract

The invention relates to a device for continuously measuring the adhesion between the fibers of rovings or similar fiber bundles, comprising: at least one drafting zone formed between a roving supply device and a roving pulling mechanism, which is driven the rollers are coupled to a separate drive to set and generate a constant draft force of the roving in the drafting zone; and a force sensor, the contact member of which extends to the path of the roving between the feeding device and the drawing mechanism and deflects the roving from the feeding The straight path between the device and the pulling mechanism, therefore, the force sensor is used to measure the force by which the roving acts on the contact member of the force sensor. The contact member of the force sensor is located in the drafting zone and at its starting point, and in the wedge-shaped space between the surfaces of the feed rollers facing the drafting zone, so that the contact member is surrounded by the roving at an angle from 1° to 40° °, preferably in the range from 10° to 20°, the length of the drafting zone is 5 mm to 15 mm greater than the length of the longest fiber in the roving being measured.

Description

technical field [0001] The invention also relates to a device for continuously measuring the adhesion between the fibers of rovings or of similar fiber bundles, the device comprising: at least one drafting zone formed between a supply of rovings and a roving Between the drawing mechanism, the feed device and the driving rollers of the drawing mechanism are coupled to a separate drive to set and generate a constant draft force of the roving in the drafting zone; and a force sensor, the contact member of the force sensor extends to the path of the roving between the feeding device and the drawing mechanism, and causes the roving to deviate from the straight path between the feeding device and the pulling mechanism, whereby a force sensor is used to measure the force by which , the roving acts on the contact member of the force sensor. Background technique [0002] During ring spinning, the roving being fed is first attenuated mechanically and then twisted. In order to produc...
