Embossing/calendering rollers are employed in the non-wovens industry for the bonding of non-wovens. We supply the most diverse of calender roller types (peripherally drilled or centre-bore with displacer). We also undertake complete re(finishing) of calender rollers, whether new or already engraved, and also surface-hardening (nitrogen case-hardening, induction hardening) and precision grinding at room or operating temperature. An exclusive technique patented by Wetzel is employed for engraving. The technique causes no additional stresses on the roller surface.
Our speciality are geometric shapes such as squares, rectangles, ovals and rhombuses.The technique achieves the best possible surface roughness at the profile edges, which reduces the incidence of fibres adhering or catching. Some engraving profiles can be applied directly to induction-hardened surfaces.
Rollers for thermal, chemical and ultrasonic bonding of non-wovens, Chemical bonding: foam impregnation rollers, Thermal bonding: thermobonding rollers, Ultrasonic bonding: ultrasonic rollers
