A circular sliver knitting machine comprising an air supply unit for supplying air to the circular sliver knitting machine. A first air nozzle unit cooperating with a card unit for directing air along a path generally radially outward toward the knitting needles and a second air nozzle unit cooperating with the card unit for directing air along a path generally radially inward toward the needles. An air distributing unit is provided for distributing air received from the air supply unit to at least one of the first air nozzle unit and the second air nozzle unit.
摘要:
An apparatus and method for knitting sliver fabric on a circular sliver knitting machine. An air blowing unit is attached to the machine so as to be oriented radially inward from the knitting cylinder and a card unit so as to blow air radially outwardly toward the needles. The air blowing unit blows air along generally horizontal longitudinal path toward the needles so as to turn free ends of the sliver fibers once the medial portions thereof have been knit into the fabric. A modified latched guard cooperates with air blowing unit for guiding free ends of the sliver fibers onto sinkers in a uniform and controlled manner to enable the free ends sliver fibers to be knit a second time by the adjacent needles.

There is disclosed an elongate piece of card clothing (10) which is rectangular as seen in plan, and which is capable of being wrapped around a carrier roll (11) having a slot (12) in its outer periphery with the free ends (18) of the card clothing (10) being received by said slot. The card clothing (10) comprises an elongate strip of resilient material (14) having opposed ends (15) which abut one another in the region of the slot (12), wire carding teeth (16) carried by the strip of resilient material (14), and an elongate carrier web (17, 17a) secured to the elongate strip of resilient material (14) and having opposed ends (18) which each project longitudinally beyond a respective end (15) of the strip (14) so as to form a gripping portion which is taken inwardly through the slot (12) to be engaged by gripping means (19) which apply tension to the web (17, 17a) in order to secure the piece of card clothing in position on the outer periphery of the roll (11).
摘要:
Apparatus and method for removing excess fibers from the doffer of a sliver high pile fabric knitting machine and returning the fibers to the main cylinder for refeeding to the doffer. Upon the return of the fibers to the main cylinder, they are combed and aligned into a uniform layer of parallel fibers for uniform redistribution on the main cylinder and uniform mixture with fresh, incoming fibers fed by the sliver feed elements. The invention includes pneumatic suction for drawing fibers from the doffer into a substantially closed suction chamber, a rotatable filter roll within the chamber, which separates the air and the fibers and discharges the fibers from the chamber, and a sealing roll permitting the fibers to be discharged from the chamber without impairing the integrity of the vacuum therein. Fiber feeding elements composed of a rotatable wire-covered fiber return feed roll and a cooperating fiber feed plate return the recovered fibers to the main cylinder.
摘要:
A wire-covered doffer for feeding fibers to the needles of a sliver high pile fabric knitting machine, in which the card clothing is of generally rectangular configuration and envelops the doffer roll so that the longitudinally spaced ends of the segment are disposed in tight abutting relationship to each other on the roll. A pair of circumferentially spaced clamps mounted on the doffer roll tightly secure the segment of card clothing to the periphery of the roll, stretching the segment slightly to impart a slight tension thereto. Each clamp supports a row of spaced points for impalement and retention of the segment of card clothing. Each row of points extends transversely relative to the periphery of the doffer roll, and penetrates the segment of card clothing at a location spaced a short distance inwardly from one of the two abutting ends of the segment. Threaded connectors affix the clamps to the doffer roll.
摘要:
Circular knitting machine for the manufacture of knit wares of hosiery with combed-in fibers, having at least one needle bed possessing knitting needles and having at least one carding machine which possesses a feed apparatus for a band of fibers, a combing-in zone, through which the knitting needles pass, for the contact less insertions of fibers into the knitting needles, and a separating apparatus for separating the band of fibers into individual fibers. The separating device comprises a separating drum that can be driven at high peripheral speed and is provided with a fitting (card wires) for which a drive mechanism is provided that is independent of the knitting machine drive mechanism. Opposite the peripheral surface of the separating drum is a cover which possesses an entrance opening for the band of fibers brought by the feed device and an exit opening for the separated fibers that opens into the combing-in zone, and which encloses the fitting, (card wires) in a separating and accelerating section disposed in the direction of rotation between the entrance opening and the exit opening, so closely that a detachment of the fibers in this separating and accelerating section is prevented.
摘要:
Improvement in sliver feeding devices for use with circular knitting machines to make sliver knitted fabric, wherein the device has comber and doffer drums each of which is covered with spirally extending wrappings of card wire cloths, wherein the wrappings on the doffer drum comprises a single individual card wire cloth extending in a single spiral, and wherein the wrappings on the comber drum comprise a plurality of individual card wire cloths extending in a plural spiral.
摘要:
A machine for producing a knitted fabric having a knitted ground material of a ground thread and a pile or loop-pile surface from additional pile threads or fibers, the machine having a plurality of individually selectable knitting elements and at least two knitting systems, each with a feeding position for the ground thread and the pile thread or a fiber web. A patterning mechanism is provided at each knitting system for selecting the particular knitting element which is to process the pile threads or fibers in that system and each knitting element having a knitting cam segment to produce the stitches.
