The Attachment Chains consists of two parallel strands on live tubular rollers . These chains are made for specific machines to deliver more work compared to normal chains. They are used in machines that may have speed variations or that have immediate stoppage. They provide additional support to the overall system. They can also be placed in slicing or wrapping machines as the attachment works as accumulators. All the attachment are assembled with connecting pins that act as a tie bars These chains have a longer life span and are stronger.
