The wire is drawn through a die located in an independent die box and is accumulated on the block before being transported through the differential assembly and OTO pulley to the next die. The BB Block features a twist-free design, equipped with a bobbin block for effective accumulation and transfer to the subsequent block, making it ideal for achieving higher speeds and better-quality finishes.

Accumulation-Type Dry Drawing Blocks
