6.3 CHAIN PATTERNS
“Pattern” chain is a combination of straight and/or offset links arranged in various repetitive sequences. The purpose of a
“pattern” is to meet various conveying, cleaning or damage prevention conditions.
An all straight link pattern creates a flat surface for minimum separation. Use this pattern in loose soil conditions to carry
soil as far as possible up, thereby minimizing potato bruising.
An all down link pattern has the same characteristic as all straight in that it creates a flat surface for minimum separation.
Again it carries the soil further up the chain for potato protection.
