Abstract
An apparatus for removing puncture-resistant tubes from tires includes two symmetrical squeezing plates, a jack located between these two plates, in a plane parallel to the lengthwise direction thereof and a base plate disposed transversely with respect to the squeezing plates, which base plate furnishes support for the squeezing plates and for a tire which is to have its associated puncture-resistant tube removed. An accommodation for the tire whose tube is to be removed, is delimited by the aforesaid squeezing plates, jack and base plate. A method of removing puncture-resistant tubes involves subjecting a tire containing a puncture-resistant tube simultaneously to a lateral squeezing action on two diametrically opposite zones thereof in a given plane, and to a first thrusting action on a zone thereof in a plane, perpendicular to the given plane, and then to a thrusting action on a zone opposite to the zone which was subjected to the first thrusting action.
