Abstract: Apparatus for blending, paralleling and cleaning fibers such as cotton and synthetics. The apparatus comprises a work roll having its surface covered with metallic wire and an arcuate, metallic wire section cooperating with a portion of the periphery of the work roll. The fiber is fed between the roll and arcuate surface, accomplishing the improved results noted in the accompanying specification.

Abstract: A drive for a textile carding machine is illustrated wherein a direct current motor is provided for returning the doffer to operating or production speed, following a run at slow speed as for putting an end up, independently of the other driven card components which is de-energized after the doffer has attained operating speed. A drive connection provided between the licker-in and the barrow pulley thereafter drives the doffer at operating speed. The method thus contemplates driving the doffer from slow to operating speed independently of the usual driving components of the card and then when the doffer is at operating speed, utilizing the usual driving components of the card to drive the doffer after discontinuing independent driving of the doffer.

Abstract: By combination and interaction of aerodynamic and mechanical forces, textile fibers are removed from a single source, transported, collected, blended, subdivided, and distributed in equal amounts to multiple remote locations, whereby the fibers are continuously assembled into uniform ribbons for subsequent textile processing or supplied directly to open-end spinning units.

Abstract: A variable speed drive system for a carding machine employs a variable pitch pulley assembly that rotates the feed cylinder and doffer cylinder at a constant slow speed as the sliver is made up to the coiler can, and after a predetermined time lapse the speed of the feed cylinder and doffer automatically and progressively increase at a fixed speed ratio from the slow speed condition to a constant high speed condition. If the sliver is not made up properly within the time lapse, the operation of the feed cylinder and doffer cylinder is automatically terminated.

Abstract: A method and apparatus whereby a carded web is removed from a rotating member carrying the web by passing the web through a mouth constituted by a nip between a rotating element such as a stripping roller which may have a non-circular cross-section and a stationary element such as a blade-like member that may be oscillated toward and away from the rotating element, the mouth continuously opening and closing in a plane radial of the rotating element.

Abstract: By combination and interaction of mechanical and aerodynamic forces, textile fibers are doffed from a processing cylinder, purged of foreign matter, subdivided and directed into a network of conveying tubes, and distributed to a multiplicity of fiber by-passing condensers wherein fibers are continuously assembled into a uniform ribbon for subsequent textile processing. The invention encompasses unique means for by-passing excess fibers for collection and reprocessing.

Abstract: The invention is employed to convey and break spin fibers and involves a single cylindrical opening means which separates a fibrous bat into individual fibers. A suitable feeding means is operably associated with the opening means and serves to feed the fiber bat to the opening means. A plurality of conduits open adjacent to the peripheral surface of the cylindrical opening means and each conduit extends to a discrete location remote from the opening means. Fibers are drawn from the peripheral surface of the opening means into and along the length of the conduits by a suction introduced through a vacuum manifold opening into the conduit. Connected to each of the conduits remote from the opening means is a break spinner which spins into yarn fibers conducted from the opening means.

Abstract: In apparatus for stripping a fibrous web from the doffer of a carding machine, provision is made for pneumatically assisting the dragging rollers to remove web from the stripping roller. This is achieved by directing air impulses towards a dragging roller from within the stripping roller. An air chamber within the stripping roller is arranged such that the impulses are directed in a predetermined direction, as apertures in the stripping roller register therewith. Carding cloth covering the stripping roller has appropriately, toothed, stepped windings.

Abstract: 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.

Abstract: A high production textile card system is provided with an automatic variable speed drive system for driving the doffing cylinder from the main cylinder at a slow speed during system start-up and then progressively increasing the speed of the doffing cylinder after start-up. A variable speed belt drive system and clutch system are responsive to the sliver detector switch at the coiler can to control the rotation of the doffing cylinder after the system startup time has elapsed, to either terminate the rotation of the doffing cylinder if the sliver has not been properly threaded through the coiler head, or to increase the speed of rotation of the doffing cylinder with respect to the speed of rotation of the main cylinder.

Abstract: A textile card crush roll operating system is driven by a two-speed electric motor completely independent of the main card cylinder driving motor and is provided with starting control means for operating the crush roll motor at slow speed for a pre-determined time according to automatically operable timing means during which interval sliver from the crush rolls is manually fed into an associated coiler and arranged in such a way that tension of the sliver is applied to stop control means which stops operation of the two-speed crush roll motor after the motor is accelerated to its high speed condition under the control of operating control means. Thus if sliver tension is substantially reduced, the crush roll system is automatically shut down.
