Flat Transmission Rubber Beltings

Company Profile:

Gilson Industries is a reputed name in the field of conveyor belt & transmission rubber

belts and has been working with a young & dynamic Technical Team under the able

guidance of its founder who has got experience of 3 decades of rubber belts.

For the promotion of productivity there is a growing need for mechanical handling of bulk

material to considerable distances even where significant differences in height and in

most cases CONVEYOR BELTS are found to be the right answer.

The objective of the company is to develop, manufacture & market conveyor belts

according to the specific requirements of an esteemed customer being in with exactly of

reliability built into item and in the modern plant of GI conveyor belts, almost all types

are manufactured confirming to IS: 1891/International standard under strict supervision

of engineers and technologist who have rich experience in this field. GI conveyor belts

are standard quality products and have been accepted extensively by innumerable

projects and industries throughout India.

We have always believed that our customer is our teacher who tells us about our

shortcomings & guide us for the future. This is the only factor by which a company grew

from strength to strength and rose to its leading position today.

Rubber Conveyor Belts: The rubber cover should be selected by taking into account the type of material to be handled and the operating condition of the belt. Conveyor belting is available in the following grades and ranging from 150 mm to 1500 mm with Moulded edge “ME” construction for Cotton belts and Cut edge construction “CE” for Nylon & EP belts in open or endless lengths.

Grade OR Recommended for carrying parts and components coated with machine oil & other oily materials. Conforming as per International Standards. Reinforcement Material NN, EP.

6) Rough Top Conveyor Belts

Grade RT These belts are specially designed with a Rough Top / Pimpled or Ribbed / Cleated carrying surface to prevent slippage. Ideally suited to carry packaged materials on gradients of more than 20º. Low friction co-efficient with bare back bottom. Two or three plies of synthetic fabrics provide high strength & flexibility.

7) Food Grade Conveyor Belts (Hygienic)

Food Grade These belts with white rubber covers do not impart odour and do not stain the materials to be conveyed and thus are particularly suitable for food processing and pharmaceuticals industries. These belts are manufactured with FDA approved polymers and are available in high abrasion resistant / antistatic / oil resistant cover grades. Conforming as per International Standards.

The Essential Characteristics of GI Conveyor Belts are: -

� High tensile resistance with low elongation.

� Good troughing and impact resistance.

� High flexibility of the carcass fabric to prevent bucking while wrapping on pulleys.

� Available up to 1500 mm width and any number of plies. s

� Good interface adhesion of components for better flex life.

� Better load carrying over long haulage.

� Available in moulded rubber or tough slit edge finish.

� Resistance to environmental operating conditions.

� Resistance to heat and to high environmental temperatures.

� Resistance to chemical products such as acid, oxidizing agents even at significant concentrations.

� Good surface electrical conductivity, good resistance to fire and flame propagations.

Flat Transmission Rubber Beltings: -

The Transmission Belts are manufactured from the best raw-materials duly tested in our Modern Laboratory. These belts are fabricated with multiple plies of specially woven fabrics with sufficient tensile strength both in wrap & weft directions. The cotton ducks (fabrics) are completely impregnated with specially formulated rubber compounds to get the best ply adhesion & excellent flex life in actual; service. The edges of belts are sealed with special binding solution to prevent ingress of moisture and fraying of the edges. Samples from finished belts are tested for quality control before being shipped. The belts are made in a wide range viz. type of fabrics, number of plies and widths to meet customer’s needs and service requirements. Fabric Types & General Specifications: -

Pulley Diameters: - Load transmission capacity of belt is directly proportional to its speed. Large diameter pulleys with increased surface speed and consequently high load capacity (of the belts), gives a greater safety to the outer plies of the belts from the effect of excessive stress and also help to regulate the load throughout the cross section of the belt.

Width Of Pulley Belt Width in MM Pulley Width in MM

Up to 125 MM Belt Width + 13 MM 125 MM to 250 MM Belt Width + 25 MM

Installation / Inspection & Care of Transmission Belts: -

1. For getting correct initial tension the length of the belt is cut shorter than the actual steel tape measurement around the pulleys on the following basis:

a) Belts upto 3 plies - 1.5% or 15 MM / Mtr. b) Belts with 4. 5 & 6 plies - 1.0% or 10 MM / Mtr. c) Belts upto 7 plies - 0.5% or 5 MM / Mtr.

2. Both ends of the belts should be square cut at the right angles to the edges and should not have ragged cotton ends.

3. Let the belt run for few minutes and read just the tension, if necessary.
