WRAPPING DEVICE WITH ELECTRIC DRIVE Russian patent published in 2014 - IPC B65B13/02 B65B13/18 B65B13/32 

FIELD: electricity.

SUBSTANCE: mobile device comprises a tightening accessory for tightening of a wrapping tape loop, a connecting accessory for connection of two loop zones lying on each other and a charged accumulator of energy for release of energy that drives with the help of a motor at least an accessory for friction welding and the tightening accessory. At the same time the drive of at least the tightening accessory and the accessory for friction welding is a brushless DC motor. The method to wrap a packed load with a wrapping tape is carried out using a mobile wrapping device that works from an accumulator battery. In the method the loop of the wrapping tape is laid around the load, then with the help of the tightening accessory tension is applied to the loop, and with the help of the connecting accessory they create a connection of two loop zones lying on each other. At the same time with the help of a brushless DC motor they provide for driving movements for the first tightening process depending on the number of rotations, and the second tightening process is carried out with the speed of the tape reverse reduced in comparison to the first one.

EFFECT: increased reliability and convenience of use.
