METHOD OF MONO-RINGS MANUFACTURING FOR BAND ROPES AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2017 - IPC B66C1/18 

FIELD: aviation.

SUBSTANCE: device contains two columns, one of which has two rollers and one clamp, and the other has the third roller. The columns are rigidly fixed to the power floor. The distance between the columns is equal to the length of the mono-ring. The roller axes are located in the same plane. The diameters of the rollers are equal to the diameters of the coils. The distance between the tape end securing clamp and the roller nearest to it, as well as the distance between this roller and fixturing point of the other tape end to the cargo, is selected from the condition of providing the necessary length of the power seams. The method of mono-rings manufacturing for band ropes is that the tape is cut under a load equal to 1-2%. After that, the tape is folded to form two loops around the edges. The cutting of the tape is carried out in a device in which one end of the mono-ring is placed in the securing clamp. Then the tape is wrapped around two rollers and the second end of the tape is thrown through the third roller and fixed to a constant weight cargo. Then, a predetermined holding time is provided under the load. After that, fasteners are fixed, which fix the given length of the mono-ring, while the holding value is constant for all mono-rings entering into one band rope. After that, the mono-ring is removed from the device. The free end is pressed and sewn to the tape. Then, in the right place of the mono ring, reinforcement from the tape is installed and sewn to it.

EFFECT: strength of the manufactured band rope consisting of several mono-rings is increased, ensuring a minimum difference in the length of the mono-rings, and the accuracy of the manufactured band rings length is increased.
