ROTOSTEAM is a modern Continuous Yarn Shrinking and Bulking Machine with independent heads suitable to shrink and bulk a very wide range of hand-knitting yarns with counts from Nm 1 to 7. The new ROTOSTEAM is designed to be linked with all type of semiautomatic and automatic ball-winding machines (especially to our Fc34-NX) or cone or cake winders (spirowaps) according to the customer’s choice.

The yarn is layed on the woven belt and then conveyed into the steaming chamber. Here the steam acts on the yarn by shrinking and bulking it. The steam is injected under pressure in the steaming chamber; when the preselected temperature is reached, the electric-valve closes the immission of the steam. The bulked yarn pass through the cooling zone and then is ready to be wound in balls, in cones or in cakes (spirowaps). A set of photocells sincronizes our ROTOSTEAM to theball-winding machines or to the cone or cake (spirowaps) winders.
