§1What this business is
Natural and synthetic rubber is masticated and compounded with rubber chemicals on mixing mills. Measured amounts of compound are moulded in a multi-daylight hydraulic press; after the first cure the sheets may be cured again under steam in a post-cure chamber, then kept under load while they cool so they do not warp. Sheets are tested and despatched. Buyers are hawai chappal, slipper and sandal makers, and footwear sole cutters.
Capacity: 75,000 sheets of 4 kg each a year.
