| Curing Presses for Tyres |
Use of the machine
Curing presses type Bag-O-Matic are determined for simultaneous moulding and curing of two bias ply tyres or radial tyres either in two-parts moulds or in segment moulds.
The curing press is designed as a double eccentric press with the main drive by means of an electric brake motor. The secondary drives are electric, pneumatic and hydraulic ones. The curing presses are designed with the plate heating or with the chamber heating. The shaping is carried out with the aid of a bladder.
The press is fitted with extensometres on the pull rods for measuring the closing force, with safety manostats to secure the safety. Further, curing presses are fitted with a valve battery for the distribution of agenses such as for heating, pressure and control agenses, central lubrication system, electric installation on the press and with an switchboard (electric cabinet)with the control system. A loader in mechanical or pneumatic execution is designed for the handling with green tyres. The unloading is assured by an unloading device.
