Abstract

Improvements in a tire wrapper, essentially characterized by the fact of understanding: a bedframe with structure where the mechanical elements constitutive of receiver-transmitter systems of the turning movement originated by a driven motor are mounted; whose systems transmit the movement to a ring-wrapper and to a tire respectively, and serve in turn to support said ring and said tire, because the system transmitter of the movement to the ring-wrapper is integrated by a pulley which by means of a belt takes the movement of a driving pulley coupled to the motor rotor shaft, and because said first pulley transmits the movement through its axis to another pulley, located at the end of the profile shaft, operatively arranged so that it supports the above mentioned pulley. Wrapping ring, and also because said ring is supported on two idler pulleys, one of them coupled to an articulated arm that presses by effects of a spring to said pulley against the ring, which lends a rigidity in its seats, and for presenting the referred ring a removable sector to allow the entrance of the tire; further comprising the ring-wrapper a roller provided with a band whose roller rotates next to the ring and braked around itself, that is, around the envelope of the tire that drags it during the wrapping.
