Debarking chain with passing links

A debarking chain configured for attachment to a debarking drum, the debarking chain comprising:

• a plurality of interconnected chain links including two end links and a plurality of intermediate links that interconnect with each other and the respective end links so that each of the end links are interconnected only with a single intermediate link, each chain link being a continuous strand of chain material defining a central opening through which the continuous strand of any adjacent, interconnected chain links pass, the plurality of intermediate links including at least one passing link;
• wherein an inner perimeter of each at least one passing link includes four arcuate sections, each arcuate section separated from the other by non-arcuate sections, such that the inner perimeter is less than substantially round;
• wherein the plurality of interconnected chain links include at least one drum attachment chain link, the at least one drum attachment chain link being an end link constructed and arranged to be securable to the debarking drum;
• wherein the interconnected links include a series of five interconnected passing links;
• and the interconnected links include a series of three non-passing links, one of which is the drum attachment link.
