Abstract
Abstract The invention concerns a method of producing a high pile fabric on a multi-feed circular weft knitting machine in which needles are selected by the machine to take loose fibres from slivers fed to card wheels at a card or brushing station. The invention consists of reselecting needles at the card station to take varying amounts of loose fibres from the preselected slivers actually during the carding or brushing operation.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
162 words
A method of producing a high pile fabric simulating an animal pelt or fur on a multi-feed circular weft knitting machine which comprises feeding a plurality of loose fibers in the form of carded slivers to a fiber-collecting station disposed adjacent a needle bed of the multi-feed circular weft knitting machine so that the needles in the bed pass the station during knitting, effecting a needle preselection on the knitting machine to raise selected knitting needles from a first, non-fiber collecting level in which the needles do not collect fibers at said fiber-collecting station to a second, fiber-collecting level in which the selected needles collect fibers from said fiber-collecting station during the passage of said selected needles past said station, permitting said selected needles to collect fiber from said fiber-collecting station, and effecting a needle reselection in predetermined pattern sequence while said preselected needles are collecting fiber from said fiber-collection station so to provide a variation in the needles which collect fiber.
Claim 2
Independent Claim
162 words
A method of producing a high pile fabric simulating an animal pelt or fur on a multi-feed circular weft knitting machine which comprises feeding a plurality of loose fibers in the form of carded slivers to a fiber-collecting station disposed adjacent a needle bed of the multi-feed circular weft knitting machine so that the needles in the bed pass the station during knitting, effecting a needle preselection on the knitting machine to raise selected knitting needles from a first, non-fiber collecting level in which the needles do not collect fibers at said fiber-collecting station to a second, fiber-collecting level in which the selected needles collect fibers from said fiber-collecting station during the passage of said selected needles past said station, permitting said selected needles to collect fiber from said fiber-collecting station, and effecting a needle reselection in predetermined pattern sequence while said preselected needles are collecting fiber from said fiber-collection station so to provide a variation in the needles which collect fiber.
Claim 3
Dependent Claim
37 words
A method as claimed in claim 1 wherein said needle reselection step causes certain of the needles selected during the step of needle preselection to be withdrawn from said fiber-collecting station and to take no further fibers.
Claim 4
Dependent Claim
56 words
A method as claimed in claim 1 wherein said needle preselection step causes some of the needles not selected during the step of needle preselection to be selected in predetermined pattern sequence and raised to said second, fiber-collecting level to collect fibers during the latter part of the passage of the needles past the fiber-collecting station.
Claim 5
Dependent Claim
47 words
A method as set forth in claim 1 wherein the step of needle reselection is performed by a tricked, pattern wheel disposed below said fiber-collecting station and which acts on butts on the needles to selectively raise or lower the needles in accordance with predetermined pattern sequence.
