Stewarts: How a 150-Year-Old Company Reinvents Precision

From British textile mills to perforating and converting technologies for the Americas, Stewarts of America brings century-old pin technology to the demands of modern sustainable packaging.

An electro-pneumatic punch perforating unit is a converting device used to create precise holes or perforation patterns in moving web materials (such as plastic film, foil, paper, or nonwovens) by combining electronic control systems with pneumatic actuation.

The next time you pull a paper mailer off your doorstep, hold it up to the light. If you look closely, you may notice something surprising: tiny, nearly invisible holes that allow the package to breathe just enough to seal cleanly at high production speeds without trapping air inside. The company behind those holes has been perfecting precision perforation technology since before most of today's packaging machinery builders existed.

20160127 131016StewartsStewarts was founded in the United Kingdom in 1874, originally to develop pinned product technology for the textile industry. Their precision-engineered cylinders and bars—containing hundreds of thousands of pins—replaced traditional wire-wound products, improving fiber handling while reducing breakage of brittle natural bast fibers, like jute, flax, and hemp.

As American textile manufacturing expanded in the 1970s, Stewarts established operations in Simpsonville, South Carolina, then a hub of U.S. textile production. When that industry contracted in the late 1990s and shifted offshore, Stewarts made a strategic pivot: applying its deep expertise in precision pin manufacturing to new industries, including perforating, packaging and converting.

A vertically integrated advantage

The company doesn't simply sell pinned products; it designs and builds complete perforation and converting systems, including auxiliary equipment such as slitters, unwind and rewind systems, and sheeting machinery. Its portfolio spans hot- and cold-pin perforation, slit perforation, inline ez-tear perforation, vertical punch, rotary punch, cross-web, laser, flame, ESD (electrostatic discharge), and vacuum perforation, as well as embossing. This enables customers to trial multiple perforation approaches under one roof.

“This integration allows for tighter control of performance outcomes, faster development cycles, and the ability to tailor systems to highly specific customer requirements,” says Craig Jackson, Managing Director.

Product development at Stewarts is application-driven by design. Ideas originate from direct customer collaboration and long-term relationships. Once a need is identified, the engineering team evaluates solutions based on performance, manufacturability, and scalability. Often, 3D modeling and SolidWorks simulations are used to validate machine fitment within existing production lines before a single piece of steel is cut. Where applicable, systems can be virtually simulated prior to build, identifying integration issues early and ensuring seamless commissioning on installation.

As the packaging industry moves toward greater connectivity and data transparency, Stewarts is evolving alongside it. In more sophisticated machine platforms, the company has begun integrating enhanced data acquisition and communication capabilities within its controls software, positioning those systems for future connectivity with plant-level analytics. At the same time, it recognizes that a significant portion of its portfolio comprises auxiliary and bolt-on equipment, where simplicity and reliability take precedence.
