{"product_id":"desenrollador-de-rodillos-para-geomembrana","title":"Roller unwinder","description":"\u003cp\u003eRolling out heavy HDPE geomembrane rolls over prepared ground —without the liner scratching against the soil, stones or the trench edge, and without wearing out the crew dragging the material by sheer force— calls for a rolling support point that reduces friction during deployment. This roller unwinder —also called a \u003cstrong\u003eroll feeder\u003c\/strong\u003e or deployment guide roller— is a \u003cstrong\u003emotor-free\u003c\/strong\u003e piece of KORWINS equipment, with a 710 × 540 mm aluminum frame and 450 mm rollers (two polyurethane and two stainless steel), designed to lay geomembrane, geotextile, geocomposite and drainage sheets with less effort and without damaging the liner surface.\u003c\/p\u003e\n\n\u003ch3\u003eKey benefits\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLess effort for the crew:\u003c\/strong\u003e the rollers spin freely and the liner advances with minimal push, avoiding the brute-force dragging that tires the crew and throws the layout off.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProtects the liner against abrasion:\u003c\/strong\u003e the material passes over smooth rollers instead of rubbing on soil, gravel or the trench edge, eliminating scratches and micro-perforations that compromise watertightness.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePolyurethane and stainless steel rollers:\u003c\/strong\u003e they combine a soft grip that doesn't mark the membrane with the rigidity of stainless steel, and withstand jobsite weather.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSturdy aluminum structure:\u003c\/strong\u003e a light but rigid frame, easy to reposition along the installation front, with good behavior against water and dust.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNo motor, no maintenance:\u003c\/strong\u003e it needs no electricity or fuel; zero consumables and ready to use in the open field.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eApplications and typical uses\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eLaying HDPE\/LLDPE geomembrane in ponds, reservoirs, landfills and canals.\u003c\/li\u003e\n  \u003cli\u003eDeploying geotextile, drainage geocomposite and protection sheets.\u003c\/li\u003e\n  \u003cli\u003eFeeding the liner toward the wedge or extrusion welding area.\u003c\/li\u003e\n  \u003cli\u003eControlled movement of heavy rolls on slopes and the floors of hydraulic works.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eQuality and durability\u003c\/h3\u003e\n\u003cp\u003eA cheap roll feeder fails when the frame flexes under the weight of the roll, when the bearings seize up with dust, or when the roller coating peels off and starts marking the liner. This equipment is built with a reinforced aluminum frame, thick-walled rollers with smooth spin and a water- and dust-resistant finish, conditions to withstand repeated jobsite use without becoming a disposable consumable.
