High Speed Mechanical Coilers

Sleeper and Hartley has a reputation built on high-speed mechanical coilers. Their revolutionary designs have always made them the choice when throughput and profit were at stake.

Patented noncircular gears provide high-speed feed that accelerates and decelerates for smooth even transitions, providing consistent production quality even at two to three times normally accepted production rates.

Why frustrate yourself trying to produce high production speeds on machines not designed for it? Invest in a Sleeper High-Speed mechanical and get the production rates you need while maintaining the quality your customer demands.
