Abstract
A carding engine having a rotatable hollow carding cylinder (5). The inner surface of the cylinder is formed with a fluid-conveying pathway (18 to 21) in a pattern such that fluid circulated through the pathway will maintain the surface temperature of the cylinder substantially uniform. Means are provided for circulating fluid through the pathway in such a way that during operation the pathway is maintained full of fluid.
Claims14
A carding engine having a hollow carding cylinder, means mounting said cylinder for rotation about a substantially horizontal axis, and bends at each side of the cylinder, in which a fluid-conveying pathway is formed on the inner surface of the cylinder in a pattern such that fluid circulated through the pathway will maintain the surface temperature of the cylinder substantially uniform, the pathway forming at least one continuous fluid path having a discrete inlet and a discrete outlet at opposite extremities thereof.
