PRODUCT STRUCTURES: take a look inside
COMPLETE ROLLER – ROLLER COVER – ROLLER SLEEVE
With paint roller, we habitually refer to the standard equipment whose length can vary from eighteen to twenty-five centimetres, suitable for medium and large surfaces. Thinking about a roller, we imagine a cylindrical body that rotates on a sinuous frame; this simple shape actually conceals many different structures and thorough technical features to ensure and maintain its functionality.
Let’s take a look at various product types on the market and delve into individual properties for appreciating the advantages and disadvantages of complete rollers, roller covers and sleeves.
COMPLETE ROLLER. It’s the comprehensive tool with fix handle: roller and frame are an inseparable unit and both components shall provide performance and handling. It means that the fibre spoilage or the handle ware due to the use requires the replacement of the whole device aside from the integrity of one of the two parts. It’s the most common structure for GDO products, DIY or single-use items and still has enduring appeal on national market as ready-to-use solution. Usually the cylindrical body is clamped on the frame through a system based on washers and fixators: a metal ring prevents the roller from slide to the steel stem, meanwhile a button or crown fixer seals the handle tip preventing the roller slipping out.
Ergon Line has introduced an alternate mechanic that optimize spin and stability due to synergic interaction between the basic features of roller and handle, avoiding any external addition and minimizing the component count susceptible to degradation. The optimize wire-frame silhouette incorporate steel prominences, calibrated to get stuck in the plastic gear inside the polypropylene roller plug. The cylinder is tight and steady, any horizontal swing caused by residual space between washer and fixator is voided. The plastic gear directs and cushions the rotation: the roller stroke, free from any metal gimmick, flows smooth and controlled both in pressure and direction. The perfect occlusion of the external bung with a central seal prevents infiltration of paint in the roller core. -------------------------------------------------------------------
ROLLER COVER. Cage system roller cover is the most essential structure and the primary way in the American market. The whole rotation mechanism is displaced on the frame and the roller is just a hollow cylinder with a plastic core to put on and off when required. Its minimalism enables versatility and convenience: one single handle can fit multiple roller types, which are cheap and easily replaceable and completely washable, inside and out.
The quality of the handle will be paramount for a well-functioning tool and an effective application. Ergon Line introduced a compact body cage system roller frame, the conventional cage is replaced by two specifically designed plastic components. A special polymer alloy and the particular push-fit shape allow a pliable and elastic insertion: the plugs compress during sliding and spread out to anchor the cover to the support. Design and diameter of the central steel wire frame are calibrated for a weighted stroke which puts an even and efficient pressure on the wall. This pressure is often dissipated by the thin metal joints of a standard cage-system frame, which will tend to lose grip (or jump) during application. The handle is light to avoid weighing down the device and keep it manageable, it’s pierced and single-component for a perfect cleaning and long-life. It fits with pole threaded insert, cone adapter not required. -------------------------------------------------------------------
ROLLER SLEEVE. Extractable roller with in-and-out system: it incorporates the whole spin mechanic for a robust professional item, the easy stick frame removal enables washing and replacement. The elaborate and stable structure accompanied by a solid wire frame with a larger diameter make up a reliable tool for a balanced and controlled roller stroke. Side plugs traction is left to an inner tube that cross the roller core from side to side merging the entire structure. In the centre of the tube is usually placed a tiny plastic cylinder called satellite, which allows the stick frame slide in and out, assures the roller anchoring to the handle stem and a smooth rolling.
Ergon Line has introduced in its sleeves a double pawl structure: the middle satellite is replaced by two cylinders encased in the side plastic gears. The rotation control is located out of the center toward the ends by enhancing stability over the entire tool length for a perfectly oriented and adherent to the wall roller stroke. In addition, the pawls at the inlet and at the top of the sleeve ease and guide the frame sliding where needed, for a quick replacement.
In order to ensure professional results, we design and implement structural components with high-technical and functional value. Our innovative mechanics aim at enhancement of every single product structure, we are constantly looking for horizontal stability and robustness to avoid paint-entry into the roller body. Our plastic components can be customized with silkscreen: a laser printer recently introduced makes it possible to refine the side plugs with a graphic pattern or your company logo, for a distinctive and unique paint roller.
