The CS1 Cotton Inserter converts cotton or synthetic coil into short lengths, forms these lengths into an inverted U shape and inserts them into bottles. First, the coil is pulled apart into a short length by feeding through two pairs of pinch rollers. This short piece is then folded and inserted up into a tube, forming the inverted U. The tube then moves over the bottle and the piece is inserted down into the bottle. The CS1 boasts several innovations which make it superior to other cottoners, including spring loaded rollers which feed almost any size or grade of cotton or synthetic coil without adjustment, exclusive cotton fingers which center the piece before it is inserted up into the tube, and a stepper-driven four-tube turret for smooth operation.
