A knife assembly for cutting an elongated web into belt loop strips for a belt loop sewing or tacker machine. The knife assembly has a blade configuration including a plurality of knife blades diverging in opposite directions along the feed path of the web. For each cutting operation, not only is the web of belt loop material severed to form a leading piece and a trailing portion, but the laterally opposite corner portions of the trailing end of the leading piece and the leading end of the trailing portion are trimmed, prior to the formation of a belt loop from each successive leading piece of belt loop material.
