Carding apparatus for textile materials.

摘要

In a carding apparatus for fibrous material, of the type in which the staple fibres are fed by a feed roller (3) to an introduction roller (4) of a carding machine and are subjected to preliminary opening and impurity removal, at least one carding unit (7,8) is provided along the path between the introduction cylinder and the carding cylinder (10). The carding unit comprises a removal knife (13) at its inlet and a guide blade (17) for the fibres at its exit, a carding surface extending therebetween. The unit is position-adjustable in directions circumferential and radial to the introduction cylinder. The knife and blade can be adjusted independently in a prevalently radial direction to the introduction cylinder. Preferably two individually adjustable carding units (7,8) are provided. Between the carding unit or units and the carding cylinder there is provided a mixing and homogenizing carding cylinder (11).
