A diagram showing how rubber sheet, fabric, linings, etc., are let off through tensioning devices into calenders, spreading machines, etc., and finally taken up on box rollers. Direction of travel and position of rubber nips are usually included in such diagrams. 

An alternative method to that of using a spreading machine or a calender for the initial preparation of fabrics for application of rubber (for composite product assembly) can be by the use of dip coaters. Application of rubber compound by this method ensures a better penetration of the fabric interstices than can be achieved by conventional frictioning techniques using calenders. More delicate fabrics which would not be strong enough for calender application can also be treated with rubber by this technique. 

The spreading machine used by the rubber industry consists of a means of applying a thin layer of rubber dough to a fabric, which then passes over a heated chest to remove solvent.

Multiply spreading is performed by a spreading machine that provides fabric feeding and transportation over the spreading table and ensures tension-free spreading (see Figure 9.2). Spreading machines can work with materials of varied types and quality, as well as with woven, nonwoven or knitted materials. Fabrics can be kept folded and rolled. 

Spreading machines are designed to work with fabrics of differing weight and are categorised according to the maximum weight of the spread fabric roll ... 

Rolls of 100—200 kg — spreading machines for medium heavy fabrics (roll diameter 500—700 mm). 

Rolls of mote than 200 kg — spreading machines for heavy fabrics (roU diameter more than 700 mm). 

The automated spreading process is performed on special tables. The main parts of a spreading machine are a fabric spreader tmck, a fabric feed system, an automatic cutting device, an end-catchCT, an operator stand panel, an encoder system, and a control panel.
