As the main load-bearing element of equipment for hot rolling and calendering of nonwoven materials, a body made of seamless alloy pipe is used, strengthened by hardening with medium-frequency currents, which has high resistance to compression and fatigue loads, and is not prone to deformation during prolonged operation under high pressure. The shaft body is precision ground, straightness and radial runout are strictly controlled, when installed in pairs, the blade absorbs uniform force, and the deviation of the surface density of the finished product is stable. Internal multi-channel heat-conducting channels provide rapid heating and uniform temperature distribution over the surface of the shaft, eliminating local overheating, which can lead to fiber destruction. The surface can be processed in three ways: mirror polishing, matte surface and pattern engraving, which are respectively suitable for glossy materials, filter fabrics and embossed non-woven materials. The shafts are adapted for high-quality lines of spunbond, meltblown and hydroentangled technologies, are able to withstand long-term operation in conditions of high temperatures and high pressure, have wear resistance and impact strength, are not prone to the formation of dents and defects, which reduces the number of defective products, and are suitable for heat treatment of non-woven materials of all types used in medical devices, industrial filters and automotive interiors.
