Abstract
A machine for blending, matting, shortening or sizing natural or artificial fibers, in which the work is performed by groups or trains of three rollers. A first working stage has a single head delivering two slivers and in which the twin bearing rollers are of large size, the two slivers emerging from the single head being fed axially or perpendicularly by directional and juxtaposing members towards a second working stage in a single lap, the width of which is at least 50% less than the width of an individual sliver. The second working stage has a reducing head which comprises a plurality of trains with twin lower retaining and traction rollers, respectively, mounted overhung on frames, adjustably spaced from one another.
Claims24
A machine for blending, matting, shortening or sizing natural or artificial fibers, comprising
- a first and second working stage, each of said stages comprising a plurality of trains of rollers adapted to perform work, each of said trains consisting of three rollers including an upper presser roller and two twin carrier rollers under said presser roller,
- said plurality of trains including, at least one single head and including said twin carrier rollers of large size constituting said first working stage, and said second working stage sequentially operatively arranged relative to said first working stage, said single head comprising means for delivering at least two separated webs of slivers of fibers therethrough,
- means for forming a narrow thick lap constituting directional juxtaposing members for feeding the two separated webs emerging from said single head along a horizontal plane towards said second working stage in a combined single lap having a width at least 50% less than the width of an individual of said two separated webs,
- said second working stage including a reducer head comprising a number of said trains, including frames and a twin lower supporting roller and control roller, respectively, overhangingly mounted on said frames, adjustably spaced from each other.
