Genernal Description

Design and Operation Features

Tube curing presses require a drive enabling the mould halves to close within the shortest possible time in order to avoid premature curing of non-vulcanized and relatively thin material in the hot mould and to launch the curing process under internal pressure as quickly as possible. Great importance, therefore, is given to the construction of the drive on tube curing presses. Even with the largest press of this model, the drive does not take more than 5.5 seconds to close the mould halves.

Another important feature is revealed by opening and closing movement of this press. In opening, the lower part of the press goes down by simultaneously tilting forward while the upper part remains fixed, thus providing a desk like loading and unloading position which is particularly advantageous in view of the flabby tubes having a relatively large diameter.

The presses are delivered with or without curing platen. However, in the case of larger tubes, mould with a steam jacket is generally used to obtain uniform curing. As the curing platen serves as mould fixation also, the upper curing platen is replaced by a special mould retaining plate in mould with a steam jacket, while the lower mould half is fixed to the table. A central adjustment installation on the upper part of the press enables quick and uniform adjustment to the various mould heights.
