Whether you are manufacturing base layers, swimwear, or high-end T-shirts, an Industrial Coverstitch Machine (also known as an Interlock Machine) is essential for professional, stretchy hems. At DH Sewing Machines, we understand that timing is everything for coverstitch reliability. Every machine we sell undergoes a rigorous technical inspection and is sewn-off by our technicians before shipping. Your machine arrives fully assembled and tested on a pallet, with the head securely boxed and the stand laid down to ensure it reaches your shop in perfect timing.
