The firs one is mainly used to produce camelbacks for the hot retreading of vehicle and 4WD tyres. This line is made up of a 8” cold-supplied extruder, type “PIN LOAD”.
There are then two other 8” and 10” hot-supplied extruders connected with a 75 lit. banbury mixer “BT5-MACCHINE MODERNE”, and a series of 3 open mills: these are designed to produce camelbacks for the hot retreading of giant tyres, earthmovers tyres, quarry trucks tyres, industrial Non-Pneumatic tyres, endless stripes and any kind of extruded compounds for technical articles.
Last but not least you will find here a series of machines for the production of calendered material: a set of open mills to plasticize and heat the compound, a thermostatic “COMERIO ERCOLE” calender with 3 rollers of 1200mm which can form 1100mm wide calendered sheets with a variable thickness between 6/10 of a mm and 80/10 of a mm (according to the type of compound); these sheets are coupled with a polytene sheet and then rolled up on a cardboard beam.
The calendered rolls can then be cut in different sizes, accordind to the customer’s request, from a minimum width of 70mm to a maximum width of 1100 mm.
