An apparatus and a method for making pipes made of a plurality of axially juxtaposed discarded vehicle tires wherein several batches of vehicle tires are sequentially compressed against one-another for forming long pipes of discarded tires. In one aspect of the apparatus of the present invention, there is provided a telescopic mandrel having a first and second spaced apart compactor plates mounted thereon for compacting a batch of vehicle tires therebetween. A plurality of grabbing jaws mounted on the telescopic mandrel at an intermediate position between the compactor plates grabs and retains the batch of tires in a compressed mode against the second compactor plate, while the telescopic mandrel is extended for loading a second or subsequent batch of vehicle tires thereon. In another aspect of the invention, there is provided several spacer strips on the telescopic mandrel for holding vehicle tires of thesame rim size in alignment with the telescopic mandrel. There is further provided a plurality of spearheaded plungers mounted on the second compactor plate for puncturing holes through the sidewalls of all tires in a batch of compressed tires and for pulling tie rods or strapping bands back through these holes. The apparatus of the present invention also comprises a band saw mounted thereon for slabbing pipes made of vehicle tires or for making square logs of discarded vehicle tires.
