A carding machine for forming a fibrous web from textile fibers comprises at least three carding cylinders arranged in succession with worker means for working fibers progressively from cylinder to cylinder, means for rotating the cylinders at successively increasing peripheral speeds in the direction of travel of the fibers, a doffer in working relationship with the last cylinder for receiving the fibers, a means for rotating the doffer at a peripheral speed less than the peripheral speed of the last carding cylinder, the last carding cylinder being rotatable at such a peripheral speed that fibers are projected from the last carding cylinder to the doffer and the doffer being placed sufficiently close to the penultimate carding cylinder without being in working relationship thereto that air flow between the penultimate carding cylinder and the doffer is restricted so that in operation a stream of air flowing with the fibers from the last carding cylinder towards the doffer meets with resistance.
A carding machine for forming a fibrous web from textile fibres comprising at least three carding cylinders arranged in succession, worker means associated with the carding cylinders for working fibres progressively from cylinder to cylinder, means for rotating the cylinders at successively increasing peripheral speeds in the direction of travel of the fibres and for rotating each successive cylinder in an opposite direction to the preceding cylinder, a doffer in working relationship with the last cylinder for receiving the fibres, means for rotating the doffer at a peripheral speed less than the peripheral speed of the last carding cylinder, and means for removing the fibres from the doffer in the form of a fibrous web, the doffer being mounted with its peripheral surface spaced from the peripheral surface of the penultimate carding cylinder by a distance between 0.017 and 0.50 inches to receive fibres projected from the last carding cylinder to the doffer through a confined space defined between the doffer, the penultimate carding cylinder and the last carding cylinder.
A process for forming a fibrous web comprising feeding textile fibres to the feed end of a carding machine including at least three carding cylinders arranged in succession and rotated at incrementally increased peripheral speeds and successively in oposite directions, working the fibres from carding cylinder to carding cylinder towards a web delivery end of the machine, rotating the last carding cylinder at such a peripheral speed that fibres carried by it are projected to a doffer, rotating the doffer at a peripheral speed less than the peripheral speed of the last carding cylinder, maintaining the doffer in a position with its peripheral surface spaced from the peripheral surface of the penultimate carding cylinder by a distance between 0.017 and 0.50 inches so as to define a confined space between the doffer, the penultimate carding cylinder and the last carding cylinder through which the fibres are projected between the last carding cylinder and the doffer, and removing the fibres from the doffer in the form of a fibrous web.
