SU99535A1 - The method of lining rubber cores of conveyor belts - Google Patents

Description

The methods of rubber coating of cores of conveyor mites are known by passing the core of the upper and dormant layers of rubber between the two rotating rolls of a doubler or calender.

A feature of the described lining method is that both resis layers are fed to a doubler or calender by a four-roll calender along conveyors.

Such an embodiment of the lining method allows an increase in the productivity of the equipment, since it eliminates the need for separate calendering of the casing rubber and its roll-up.

The drawing is a diagram of the implementation of the method.

The core roll is installed in the roll stand 1, for which the upper feed conveyor 2 sections are diluted.

The end of the core is tucked into the gap between the centering rollers 3 and is pulled through to the horizontal portion of the lower feed conveyor 4.

The facing rubber coming from the upper and lower rolls of the four-shaft calender 5 is cut and fed to the upper and lower feed conveyors driven by the calender and having the same rotational speed of the drums.

In section 6, the core is lined with upper and lower layers of lining rubber and the resulting tape is fed into the roll gap of the first backup 7, where the tape is duplicated. Then the edges of the tape are folded, which are rolled up in the second doubler 8.

Next, the tape is powdered in the powder machine 9 and rolled up on the friction sealing strut 10.

Subject invention

The rubber lining method of the cores of conveyor belts, by passing the core of the upper and lower layers of abrasive rubber between two rotating rolls of a doubler or calender, is distinguished by the fact that both rubber layers are fed into a doubler or calender by a four-shaft calender along conveyors.
