The Ringbuilder 3000 is a building machine designed by Marangoni Retreading Systems for large retreaders, and is able to produce at least 200 RINGTREAD tyres in an 8 hour shift.
Wile at the same time occupying a small space and featuring a high level of automation that guarantees outstanding productivity, savings in labour and faster processing times.
The RB 3000 makes it possible, with just one fully automated machine, to extrude the cushion gum directly onto the casing, fill the craters, apply and suitably roll the ring, thus creating a tyre that is ready to be cured.
The machine is capable of producing up to 80 tyres per eight hour shift, and its’ easy to use operating system allows the user to apply a thin, overlapping strip of extruded cushion gum during multiple rotations on to the crown and shoulder of a tyre-casing. This strip size cushion, while is not totally eliminating the need to fill larger craters, permits a reduced and precise application of the right quantity of cushion-gum.
