Description

FIELD OF THE INVENTION The invention relates to the textile industry and relates to a device for rubbing fabrics.

The aim of the invention is to improve the measurement accuracy of the abradable tissue sample by maintaining the tension of the tissue sample constant.

FIG. 1 shows a device for the abrasion of a tissue sample, a general view, in FIG. 2 shows a hollow disk, cross section; FIG. 3 - swivel drum with rods.

The device for abrasion of the fabric sample contains a carriage mounted on the housing 1 with the possibility of reciprocating movement of the carriage, carrier disks 2 and 3 with holders 4 for the ends of the fabric sample 5 located between the presser 6 and the support rollers 7, two cylinders of abrasive material 8 and means for sampling a tissue sample, including two overrunning clutches 9 and 10, located inside the hollow disk 3, and a sleeve 11 mounted loosely on the axis 12 of the hollow disk 3 and rigidly connected to the stop 13, which interacts with spring-loaded w eye 1A SET copulating in the rotary cup 15 of the housing 1.

The outer race 16 and 17 of the sleeves 9 and 10 are rigidly mounted on the hollow disk 3, and the inner sleeves 18 and 19 of the sleeves 9 and 10 are rigidly mounted one (18) on the sleeve 11, and the other (19) on the fixed axis 12 of the hollow disk 3

Couplings sleeves are connected with the sleeve 11 to the axis 12 and the hollow disk 3 through the corresponding keys 20-23. I

The device works as follows.

After fixing the ends of the sample of fabric 5 on the disks 2 and 3 with the help of holders 4, the carriage drive is activated, which performs a reciprocating movement. At the point of contact of the stretched tissue sample with the abrasive material moving the wasps along the support roller 7 from one cylinder 8 to another, abrasion of the tissue sample occurs.

In the abrasion process, the fabric is lengthened. During the reciprocating movement of the carriage with disks 2 and 3 to the extreme right position, the stop 13 interacts with the spring-loaded rod 14 and rotates around the fixed axis 12 of the hollow disk 3.

In this case, together with the abutment, the sleeve 11 is rotated, which, by means of the pins 20 and 22 and the overrunning clutch 9, rotates the hollow disk 3. By rotating the hollow disk on which the end of the sample is fixed, the residual length of the fabric sample is sampled. The outer 1Q per sleeve 17 of the sleeve 10 then rotates with the hollow disk 3.

However, the same overrunning clutch 10 by means of a key 21 connecting the inner race 19 of the clutch 10 with a non-movable axle 12 prevents rotation of the hollow disk in the opposite direction caused by the tension from the tissue sample between the two disks.

Thus, such an implementation 21) of the proposed device allows sampling of residual sample elongation for each cycle of abrasion and keeps the sample tension during the abrasion process 5 constant, which significantly increases the measurement accuracy, increases the reliability of operation (eliminates fabric sample meetings) and reduces test time.
