Abstract

Abstract A feed assembly and method for a carding machine is disclosed which includes a series of individual presser levers 22 pivotably carried adjacently above of a feed roll 16 on a carding machine frame 10 to which a lap 14 of fibers is fed via a feed plate 12. The presser levers incrementally apply an even pressure to the lap so that control of the fibers on the feed roll is maintained as they are grabbed off by a licker-in 18.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 176 words
Apparatus for feeding a lap of fibers to a carding machine of the type which includes a feed roll which feeds fibers to a licker-in roll and a feed plate over which a layer of said fibers are conveyed to the feed roll, said apparatus comprising: a plurality of individual segmented presser means carried adjacent said feed roll; and means mounting said presser means to be individually movable towards and away from said feed roll; said individual segmented presser means being arranged generally side-by-side continuously without interruption across the entire length of said feed roll for applying an even uniform pressure segmentally to segments of the lap of fibers continuously across the width of the lap for retaining control of fibers at the nip of said rolls should a fiber lump raise one of the presser means above the other presser means; and biasing means urging said presser means individually toward said feed roll exerting an even pressure against said lap of fibers along said feed roll regardless of the thickness of said layer of fibers.
Claim 2
Dependent Claim 176 words
Apparatus for feeding a lap of fibers to a carding machine of the type which includes a feed roll which feeds fibers to a licker-in roll and a feed plate over which a layer of said fibers are conveyed to the feed roll, said apparatus comprising: a plurality of individual segmented presser means carried adjacent said feed roll; and means mounting said presser means to be individually movable towards and away from said feed roll; said individual segmented presser means being arranged generally side-by-side continuously without interruption across the entire length of said feed roll for applying an even uniform pressure segmentally to segments of the lap of fibers continuously across the width of the lap for retaining control of fibers at the nip of said rolls should a fiber lump raise one of the presser means above the other presser means; and biasing means urging said presser means individually toward said feed roll exerting an even pressure against said lap of fibers along said feed roll regardless of the thickness of said layer of fibers.
Claim 3
Dependent Claim 52 words
The apparatus of claim 1 wherein each said presser means includes a presser lever having a concave feeder surface carried adjacently above said feeder roll to define a gap therebetween including a nose portion terminating closely adjacent a point of transfer of said fibers from said feed roll to the licker-in roll.
Claim 4
Dependent Claim 18 words
The apparatus of claim 2 including stop means limiting movement of said presser lever toward said feed roll.
